[DEV] Modified Skype app with Video

Hi,
I modified the recently leaked skype w/ video app for the HTC Thunderbolt. Let me document my changes and progress so far:
Here is the original app:http://www.droid-life.com/2011/04/11/download-skype-with-video-on-android/
1) if you try to install the app unmodified on a non HTC thunderbolt phone, you will get an "installation failed" message. I decompiled the app using these instructions: http://jack-mannino.blogspot.com/2010/09/reversing-android-apps-101.html
2) I modified the AndroidManifest.xml to remove this line:
<uses-library android:name="com.htc.device" />
3) I then recompiled and resigned the app( http://www.addictivetips.com/mac-os/auto-sign-tool-for-android-developers-on-mac/).
4) The apk now installed on my Nexus S but I get this error when I opened it:
"Sorry, your phone is not able to use this version of Skype. To find out more about Skype on mobile, visit www.skype.com"
5) I looked through the code and found the offending text in com.skype.ui.SplashScreenActivity.class:
protected void onResume()
{
super.onResume();
if (!f.a())
{
Toast.makeText(this, "Sorry, your phone is not able to use this version of Skype. To find out more about Skype on mobile, visit www.skype.com", 1).show();
finish();
}
.....
I commented out the toast and finish() line and then recompiled and resigned.
6) The apk installs but crashes when I try to open it:

This is my progress so far and here is my modified apk:http://www.mediafire.com/?l6xddlun3u52ung

Does this enable the use of the back camera instead of the front?
For my wife's fascinate
Sent from my ADR6400L using XDA Premium App

@eyeburn : Thanks for the investigation.
Could you try to remove the " if statement " instead ?
I guess the shared library is not only for security, but we will see that later.

More updates. I looked at the SplashScreenActivity.smali code and removed this line:
invoke-virtual {p0}, Lcom/skype/merlin_mecha/ui/SplashScreenActivity;->finish()V
this basically disables the the exiting(the finish() in the code below) of the program during the verizon phone check.
Now the phone doesn't crash but just stays at the "skype mobile" splash screen with the skype background.
I'll look at this again tomorrow. Gonna sleep now.
Updated apk as of midnight Apr 12: http://www.mediafire.com/?eqgr111a7agg3qv
My current thinking is the app is stuck in this while loop:
protected void onResume()
{
super.onResume();
if (!f.a())
{
Toast.makeText(this, "Sorry, your phone is not able to use this version of Skype. To find out more about Skype on mobile, visit www.skype.com", 1).show();
finish();
}
while (true)
{
return;
Intent localIntent1 = new Intent(this, SignInActivity.class);
boolean bool1 = getIntent().getBooleanExtra("LaunchedBySyncAdapter", 0);
Intent localIntent2 = localIntent1.putExtra("LaunchedBySyncAdapter", bool1);
int i = getIntent().getIntExtra("PostLoginCommand", 0);
Intent localIntent3 = localIntent1.putExtra("PostLoginCommand", i);
String str = getIntent().getStringExtra("PostLoginDataUri");
Intent localIntent4 = localIntent1.putExtra("PostLoginDataUri", str);
ac localac = new ac(this, localIntent1);
monitorenter;
try
{
this.a = localac;
Handler localHandler = this.b;
Runnable localRunnable = this.a;
boolean bool2 = localHandler.postDelayed(localRunnable, 1500L);
monitorexit;
continue;
}
finally
{
localObject = finally;
monitorexit;
}
}
throw localObject;
}
}
I keep getting this messages on my logcat:

More likely, that you killed the login intent, which supposed to invoke login activity. You already have 'return' as the first statement of the while loop. The code in it's current state doesn't make sense to me. It should be an exist condition from the loop, otherwise the only way to exit the loop is via exception, which will effectively kill the application.

same conclusion here, but I assume this part of code is badly decompiled. There are several other while->true->return in this code.

This is what is happening now.

Keep up the good work, a LOT of people will love you if you can get this to work on other phones like the Galaxy S.

Agreed keep up the good work....and Thanks

speaking as someone with a G Tablet, I really want this to work, so please take all the encouragement i can offer!

Keep up the good work.

Oh thank you.
Seriously, I posted about how somebody should modify this to work on all phones yesterday.
As for me, I'm getting "Sorry1, your phone is not able to use this version of skype"
(Wonder why it says "Sorry1")
I'm using a mytouch 4g with cm7 stable

Working on the same thing here on my EVO. I tried your APK but I don't get to the sign-in screen. I removed the same line from the AndroidManifest.xml file that you did so that it would install. I took a different approach and modified the VerizonNetwork and VerizonMerlin check to return 0x1 instead of 0x0 so that it gets by the Toast successfully and I get the sign-in screen. Now after I sign-in, the service crashes.

daryel - i tried it and the same happened to me, but there was nothing that said the app force-closed. it simply closed itself and that was that.
it looks like real headway is being made here. I will faithfully watch this until it is finished

oh the sorry1 was a debugging thing hehe.
so it is now crashing in com.skype.merlin_mecha.service.a
Looks to be failing some fingerprint checking. I guess this is where it verifies the phone.

I wonder which file this line is coming from:
I/StartSkypeKitOperation(17177): REMOVE THIS ONCE VERIFIED: appToken = KdXVSo6qB9
New Edit:
Ok the verification is done in com.skype.merlin_mecha.startup.SignInActivity.
I am speculating, the check and crash is in:
protected void onCreate(Bundle paramBundle)

Thanks guys, it looks like you are pretty close to the solution.
Finger crossed

Sorry but where is this Verizon check?

There are 2 .so missing.
if you look in a/a/a.smali you will find a ref to
/data/data/com.skype.merlin_mecha/lib/libskype_jni.so
And com\skype\a\c.smali has a ref to /data/data/com.test.java_surface/lib/libskype_jni.so
that means there is more to this

[Q] What is wrong with my project?

Hi all, I'm fairly new to Java and my overall coding skills are not as advanced as I'd like them to be but I really would appreciate it if someone could help me with this problem.
My first goal is to code an application for Android which measures the acceleration (X, Y, Z directions) and displays the values in a TextView.
There will be other user configurable options like unit conversion or limits with audio warnings etc. later on.
Right now I only have a few lines of code and the application already force closes right after starting.
I am posting my MainActivity.java, my activity_main.xml and the sensoractivity2 Manifest. Please point me in the right direction!
MainActivity.java:
Code:
package com.example.sensoractivity2;
import android.app.Activity;
import android.hardware.Sensor;
import android.hardware.SensorEvent;
import android.hardware.SensorEventListener;
import android.hardware.SensorManager;
import android.os.Bundle;
import android.widget.TextView;
public class MainActivity extends Activity implements SensorEventListener{
private SensorManager sensorManager;
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
sensorManager=(SensorManager) getSystemService(SENSOR_SERVICE);
sensorManager.registerListener(this, sensorManager.getDefaultSensor(Sensor.TYPE_ACCELEROMETER), SensorManager.SENSOR_DELAY_NORMAL);
}
public void onSensorChanged(SensorEvent event) {
float x, y, z = 0;
if (event.sensor.getType()==Sensor.TYPE_ACCELEROMETER) {
x=event.values[0];
y=event.values[1];
z=event.values[2];
TextView tx = (TextView) findViewById(R.id.textView1);
tx.setText((int) x);
TextView ty = (TextView) findViewById(R.id.textView2);
ty.setText((int) y);
TextView tz = (TextView) findViewById(R.id.textView3);
tz.setText((int) z);
}
}
[user=439709]@override[/user]
public void onAccuracyChanged(Sensor arg0, int arg1) {
// TODO Auto-generated method stub
}
}
activity_main.xml
Code:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"

android:layout_width="match_parent"
android:layout_height="match_parent"

<TextView

<TextView
android:id="@+id/textView3"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:text="Z-Wert" />
</LinearLayout>
sensoractivity2 Manifest:
Code:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"

</application>
</manifest>

First thing I see is that you are not setting your view in your activity classes "oncreate" method. Can you post your logcat output when the app force closes? That will help the most.

Could you please post a logcat?
Just the lines of your app. Get it using the logcat view in Eclipse.

Look at the bold for changes that will help you. When you are working with view objects, you shouldn't create the object in a listener or something that is called over and over. You will be creating a memory leak.
Code:
package com.example.sensoractivity2;
import android.app.Activity;
import android.hardware.Sensor;
import android.hardware.SensorEvent;
import android.hardware.SensorEventListener;
import android.hardware.SensorManager;
import android.os.Bundle;
import android.widget.TextView;
public class MainActivity extends Activity implements SensorEventListener{
private SensorManager sensorManager;
[B]TextView tx = null;
TextView ty = null;
TextView tz = null;[/B]
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
sensorManager=(SensorManager) getSystemService(SENSOR_SERVICE);
[B] setContentView(R.layout.activity_main);[/B]
sensorManager.registerListener(this, sensorManager.getDefaultSensor(Sensor.TYPE_ACCELEROMETER), SensorManager.SENSOR_DELAY_NORMAL);
[B]tx = (TextView) findViewById(R.id.textView1);
ty = (TextView) findViewById(R.id.textView2);
tz = (TextView) findViewById(R.id.textView3);[/B]
}
public void onSensorChanged(SensorEvent event) {
float x, y, z = 0;
if (event.sensor.getType()==Sensor.TYPE_ACCELEROMETER) {
x=event.values[0];
y=event.values[1];
z=event.values[2];
[B]tx.setText((int) x);
ty.setText((int) y);
tz.setText((int) z);[/B]
}
}
[user=439709]@override[/user]
public void onAccuracyChanged(Sensor arg0, int arg1) {
// TODO Auto-generated method stub
}
}

Here is the part of the catlog which I believe to be relevant when the crash occurs:

Thanks for your hints, zalez! Going to try that now.

The logcat states a nullpointer error. I believe my corrections will fix at least that error.

It needs to be
Code:
tx.setText(String.valueOf(x));
ty.setText(String.valueOf(y));
tz.setText(String.valueOf(z));
If you pass an int, the TextView thinks that it is a resource id. That is why you need to convert it to a String first.

I over looked the bold part. When setting text for a Textview, it has to be in string format. There is no implied conversion.
Code:
package com.example.sensoractivity2;
import android.app.Activity;
import android.hardware.Sensor;
import android.hardware.SensorEvent;
import android.hardware.SensorEventListener;
import android.hardware.SensorManager;
import android.os.Bundle;
import android.widget.TextView;
public class MainActivity extends Activity implements SensorEventListener{
private SensorManager sensorManager;
TextView tx = null;
TextView ty = null;
TextView tz = null;
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
sensorManager=(SensorManager) getSystemService(SENSOR_SERVICE);
setContentView(R.layout.activity_main);
sensorManager.registerListener(this, sensorManager.getDefaultSensor(Sensor.TYPE_ACCELEROMETER), SensorManager.SENSOR_DELAY_NORMAL);
tx = (TextView) findViewById(R.id.textView1);
ty = (TextView) findViewById(R.id.textView2);
tz = (TextView) findViewById(R.id.textView3);
}
public void onSensorChanged(SensorEvent event) {
float x, y, z = 0;
if (event.sensor.getType()==Sensor.TYPE_ACCELEROMETER) {
x=event.values[0];
y=event.values[1];
z=event.values[2];
tx.setText[B](Integer.toString(x)[/B]);
ty.setText([B]Integer.toString(y)[/B]);
tz.setText([B]Integer.toString(z)[/B]);
}

Yes! That did the trick! Now my next problem is that I only see one value instead of three, from there on I will try to move on by myself.

Sorry, I'm not sure if this is relevant, but you aren't overriding your onCreate method? Could that have anything to do with it?

He just did not wrote the @override annotation before that. As far as i know, you do not have to use it.
EDIT: Yep, it does not matter. See this: http://stackoverflow.com/questions/94361/when-do-you-use-javas-override-annotation-and-why
It says that it is just for ensuring that you are overriding the right method and for making the code easier to read.

Hi all, I am a bit further with my project since I found some time to work on it again.
//edit, force closes on starting fixed!
Here is what it is supposed to be doing: It reads the x, y and z values for acceleration from the LINEAR_ACCELERATION sensor. If a certain value is exceeded a timer will be started. If the amount of seconds the timer counts is higher than a defined threshold, it will play the default notifcation sound.
If the value from the sensor is below the threshold, it will stop the timer. The whole timer thing isn't working, the notification is played as soon as the normal acceleration threshold is passed and the time is ignored.
Please review my code below and tell me what I'm not seeing here, note that I'm still a noob.
Also I'm interested in a method to capture the maximum values read from the sensor and put it in a textview, can you help me?

Yay German code (live there, too) xD Initialise your seconds in your onCreate, it's much nicer and probably the problem. A method gets the highest value the sensor measured would be a simple
Code:
double savedVal=0; //or any other type
private void updateMaxVal(){
double currentVal =// get the value from the specific sensor
if(savedVal<currentVal) {
savedVal = currentVal;
// maybe save the time as well
}
You'd have to put that method in the onsensorchanged so it will be called often. Then update your text View with the new saved value

Hey fellow German!
If I initialise the seconds variable in the onCreate part it says that the variable is not being used (yellow marking) and in the code below I get an error obviously stating that the variable is unknown. ^^
I have three different values, how can I link the x, y and z variables in the method and how can I make sure the variables are known inside of the method? (Same problem as above)

Since I don't know how to do it with a method I just wrote the following code in my onsensorchanged part, the problem is that the max value textviews always show the same as the current value textviews:
float savedValX = 0;
float savedValY = 0;
float savedValZ = 0;
float currentValX = event.values[0];
float currentValY = event.values[1];
float currentValZ = event.values[2];
if (savedValX < currentValX) {
savedValX = currentValX;
xM.setText("X max: "+(Math.abs(Math.round(currentValX * 1000) / 1000.0)));
}
if (savedValY < currentValY) {
savedValY = currentValY;
yM.setText("Y max: "+(Math.abs(Math.round(currentValY * 1000) / 1000.0)));
}
if (savedValZ < currentValZ) {
savedValZ = currentValZ;
zM.setText("Z max: "+(Math.abs(Math.round(currentValZ * 1000) / 1000.0)));
}
Also I still have the problem that my seconds interval is being ignored.
//edit, fixed it! Now I only need the max value method.

OK so I now understand what you are trying to do with your Chronometer, the problem is that you reinitialize it every time the onSensorChanged is called so if you then ask for the seconds it has just started. To fix this, you could set an onChronometerTickListener and set your textViews in that method. To avoid recreating the Chrono use
Code:
if(chrono==null){
chrono = new Chronometer();
chrono.start();
}
If u don't want the tick listener or it doesn't work ( haven't used it yet) you can put your if(seconds<...)in the else {}of above method. But remember that the onSensorChanged is called EVERYTIME the sensor registers a change, this might be very often or just sometimes, so there is no guarantee that the text views will be updated if the else clause in that method is used
PS forget about the initializing of the seconds, I don't know what I was thinking yesterday, but I guess it was too late ...
/*edit:
What I meant with
Code:
double savedVal=0; //or any other type
private void updateMaxVal(){
is that you save your value in your class ("globally"), so that it is accessible to the whole class.
and to do it nicely you can do it like this:
Code:
float savedValX = 0;
float savedValY = 0;
float savedValZ = 0;
boolean change = false;
private void updateMaxVals(SensorEvent event){ // call this method in your onSensorChanged
change = false;
savedValX = getMax(event.values[0], savedValX);
if(change){
xM.setText("X max: "+(Math.abs(Math.round(savedValX * 1000) / 1000.0)));
}
savedValY = getMax(event.values[1], savedValY);
if(change){
yM.setText("Y max: "+(Math.abs(Math.round(savedValY * 1000) / 1000.0)));
}
savedValZ = getMax(event.values[2], savedValZ);
if(change){
yM.setText("Z max: "+(Math.abs(Math.round(savedValZ * 1000) / 1000.0)));
}
}
private float getMax(float currentVal, float savedVal){
if(currentVal > savedVal){
change = true;
return currentVal;
}else{
change = false;
return savedVal;
}
}

[CODE][Q] Pass extra twice(image to mms), or use lastIndexOf() to get file?

Ok so this may get sort of complicated, but I'll try to explain it simply.
I have a mainActivity(viewpager). i take a screenshot of this from ABS options menu. This gets saved to sdcard . WORKS FINE
Code:
this is selecting from the actionbar menu
else if (item.getTitle().toString().equalsIgnoreCase("Take Screengrab")) {
View v1 = R1.getRootView();
v1.setDrawingCacheEnabled(true);
Bitmap bm = v1.getDrawingCache();
Util.saveBitmap(bm, "folder", "screenshot");
//the above are the folder I chose to name, and the screenshotname{without additional numbering}
BitmapDrawable bitmapDrawable = new BitmapDrawable(bm);
image = (ImageView) findViewById(R.id.image4);
//imageview is above. second ativity is below
Intent intent = new Intent(this, Screenshots.class);
intent.putExtra("image", bm);
//"image" is my extra
startActivity(intent);
I send that while its saving, to an ImageView in a second(normal) activity. WORKS FINE
Code:
[user=439709]@override[/user]
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.screenshots);
//The ImageView where the screenshot goes
ImageView image=(ImageView)findViewById(R.id.image4);
//This "imageId" isnt used, but for some reason the Imageview wont set without it
Intent intent = getIntent();
int imageId = intent.getIntExtra("imageId", -1); // -1 would be a default value//
//this gets my extra
Bitmap bm = (Bitmap)this.getIntent().getParcelableExtra("image");
image.setImageBitmap(bm);
I have a button to share it, it opens with picture attached. SORT OF WORKING
The thing is, I want to automatically pass this same extra Bitmap and attach it to the message.
i can open a message with a known file attached.
Code:
{
Uri smsUri = Uri.parse("tel:0000000");
Intent intent = new Intent(Intent.ACTION_SEND, smsUri);
intent.setType("image/*");
intent.putExtra(Intent.EXTRA_STREAM, Uri.parse("file:///sdcard/folder/screenshot.png"));
intent.putExtra(Intent.EXTRA_TEXT,"Today");
startActivity(intent);
i tried the working in putExtra to the message, but I get a toast from the messaging app "Sorry, cannot attach this image". NO STACK ERRORS. nothign in the logs I can use.
Code:
Uri smsUri = Uri.parse("tel:0000000");
Intent intent = new Intent(Intent.ACTION_SEND, smsUri);
intent.setType("image/*");
intent.putExtra(Intent.EXTRA_STREAM, Uri.parse("image"));
intent.putExtra(Intent.EXTRA_TEXT,"Today");
startActivity(intent);
and other stuff like that that.
I currently am loading a known file into the message and it works perfect. Problem is, I wont know the name of the file, because my screenshots get saved as image1, image2, etc. So it will be different in every case.
So im wondering if its even possible to pass and extra through twice like that, or if I should look into return the latest image in that sdcard folder with like lastIndexOf(), or something similar.
basically, is there a way to simply query find and attach the highest numbered file? without a GUI(i can do select from gallery, but am trying to make it more automated).
any thoughts would be appreciated.
P.S. i know about the lint errors and things, and somewhat sloppy self taught java, but its working. only worried about the image passing.

image.setImageBitmap(bm);
I have a button to share it, it opens with picture attached. SORT OF WORKING
The thing is, I want to automatically pass this same extra Bitmap and attach it to the message.
i can open a message with a known file attached.
Code:
{
Uri smsUri = Uri.parse("tel:0000000");
Intent intent = new Intent(Intent.ACTION_SEND, smsUri);
intent.setType("image/*");
intent.putExtra(Intent.EXTRA_STREAM, Uri.parse("file:///sdcard/folder/screenshot.png"));
intent.putExtra(Intent.EXTRA_TEXT,"Today");
startActivity(intent);
i tried the working in putExtra to the message, but I get a toast from the messaging app "Sorry, cannot attach this image". NO STACK ERRORS. nothign in the logs I can use.
Code:
Uri smsUri = Uri.parse("tel:0000000");
Intent intent = new Intent(Intent.ACTION_SEND, smsUri);
intent.setType("image/*");
intent.putExtra(Intent.EXTRA_STREAM, Uri.parse("image"));
intent.putExtra(Intent.EXTRA_TEXT,"Today");
startActivity(intent);
and other stuff like that that.
I currently am loading a known file into the message and it works perfect. Problem is, I wont know the name of the file, because my screenshots get saved as image1, image2, etc. So it will be different in every case.
So im wondering if its even possible to pass and extra through twice like that, or if I should look into return the latest image in that sdcard folder with like lastIndexOf(), or something similar.
basically, is there a way to simply query find and attach the highest numbered file? without a GUI(i can do select from gallery, but am trying to make it more automated).
any thoughts would be appreciated.
P.S. i know about the lint errors and things, and somewhat sloppy self taught java, but its working. only worried about the image passing.

I would just pass the filename to the share intent. In your saving method return the file name and pass it to the Uri.
lastIndexOf is a bad idea. What will you do if somebody saves a file called "xyz" in the same directory? The app will send this every time. So store the filename and pass it to the Uri.

Yeah I had originally tried going about it that, with like getFileStreamPath and things like that, tried about a dozen different things but couldnt get them working. best i can get is that "sorry cant add..." message from the messaging app, which tells me that its passing the image, but it cant attach for some unknown reason(too large doesn't seem right, cuz i can do it with the known file name).
im a dum dum a probably should put this util class
Code:
static String saveBitmap(Bitmap bitmap, String dir, String baseName) {
try {
File sdcard = Environment.getExternalStorageDirectory();
File pictureDir = new File(sdcard, dir);
pictureDir.mkdirs();
File f = null;
for (int i = 1; i < 200; ++i) {
String name = baseName + i + ".png";
f = new File(pictureDir, name);
if (!f.exists()) {
break;
}
}
if (!f.exists()) {
String name = f.getAbsolutePath();
FileOutputStream fos = new FileOutputStream(name);
bitmap.compress(Bitmap.CompressFormat.PNG, 100, fos);
fos.flush();
fos.close();
//how to get "name" in third activity
return name;
}
} catch (Exception e) {
} finally {
/*
if (fos != null) {
fos.close();
}
*/
}
return null;
}
So I have the name there, but just cant get it over to the messaging. I'm wondering if I should take the pic and automaticaaly pin it to the MMS, and skip the imageview part?

First: Please get a logcat.
Second: This should be working if you use the right path:
Code:
Uri smsUri = Uri.parse("tel:0000000");
Intent intent = new Intent(Intent.ACTION_SEND, smsUri);
intent.setType("image/*");
intent.putExtra(Intent.EXTRA_STREAM, Uri.parse("<path here>"));
intent.putExtra(Intent.EXTRA_TEXT,"Today");
startActivity(intent);
(got it from your first post)

1. This is a for instance situtation of if i try sliding the extra or something else into Uri.parse()
E/Mms/compose( 1063): DRM error in onActivityResult()!
E/Mms/media( 1063): IOException caught while opening or reading stream
E/Mms/media( 1063): java.io.FileNotFoundException: No content provider: image
But the content of image makes it into the ImageView(as "getParcelableExtra("image"), just not in the MMS, so I don't know.
2. Yeah it works Perfect when I hardcode in a file( sdcard/folder/image1.png). attaches and sends perfect.
The problem is basically I have a loose understanding of how I should be doing this, and just cant figure out how I should properly be getting it to load.
Banging my head against the wall on this one. lol. :fingers-crossed:

The problem is that you do not pass the right file name. So it cannot find the file.
---------- Post added at 07:55 PM ---------- Previous post was at 07:48 PM ----------
Change it to this and tell us the log output:
Code:
static String saveBitmap(Bitmap bitmap, String dir, String baseName) {
try {
File sdcard = Environment.getExternalStorageDirectory();
File pictureDir = new File(sdcard, dir);
pictureDir.mkdirs();
File f = null;
for (int i = 1; i < 200; ++i) {
String name = baseName + i + ".png";
f = new File(pictureDir, name);
if (!f.exists()) {
break;
}
}
if (!f.exists()) {
Log.d("file", "file does not exist");
String name = f.getAbsolutePath();
FileOutputStream fos = new FileOutputStream(name);
bitmap.compress(Bitmap.CompressFormat.PNG, 100, fos);
fos.flush();
fos.close();
//how to get "name" in third activity
if (name != null) {
Log.d("return", name);
} else {
Log.d("return", "name = null");
}
return name;
} else {
Log.d("file", "file exists");
}
} catch (Exception e) {
e.printStackTrace();
} finally {
/*
if (fos != null) {
fos.close();
}
*/
}
Log.d("return", "null");
return null;
}
I just inserted some debugging things. Check the logcat (and post it).
Did you add this to your manifest?
Code:
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

i know! I just need a way to get what my Util class returns as name. then open that attached to Message. It seems like it should be a lot easier than I am making it.
i added your logs, but the only match back I get is here (I put in some extra stuff)

Yeah, I took 162 screenshots so far trying to get this. lol.
And yeah I declared the right permissions and everything. It takes the screenshot, saves it, and passes it to an ImageView in a different activity perfectly.
I can open Messaging, or FB,picassa, etc. It appends the text, but no image. BUT, i can simply hit attach from the opened message, and add in whatever picture I want.
I thought about just sending people into the gallery to pick, but the android numbering convention doesn't load images in sequential order, but a sort of numerical alphabetical( it saves likes 1, 10, 11,12,13,14,15,16,17,18,19,2,20,21,22,etc). At least this is with quickpic.
So they really get jumbled up, especially with 100+ in there(1, 10,100,11,12). And the point of this segment of the app is to share the most recent image.
i also dont want to just use the currentsystem time, because a ton of numbers is too confusing if they want to find a different one.
Thanks a lot for the help.

Let's try:
Code:
[COLOR="Red"]String path = Utils.saveBitmap(bitmap, dir, baseName);[/COLOR] //replace Utils by your class name
Uri smsUri = Uri.parse("tel:0000000");
Intent intent = new Intent(Intent.ACTION_SEND, smsUri);
intent.setType("image/*");
intent.putExtra(Intent.EXTRA_STREAM, Uri.[COLOR="Red"]fromFile(path)[/COLOR]);
intent.putExtra(Intent.EXTRA_TEXT,"Today");
[COLOR="Red"]intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_EXCLUDE_FROM_RECENTS);[/COLOR]
startActivity(intent);

Took awhile to get Eclipse to accept it, but now I get

Post your code. We cannot help you if you just say "I changed this line."
It is not getFile but fromFile.

HaHa I know, im not trying to throw puzzles out at people randomly.
But the errors in the log were from those new lines(in red)
the string path
and fromFile path ones
I may be getting somewhere with this though, i found a little section on stackoverflow that i hadn't seen in the other 30 questions about images or screenshots. :fingers-crossed:
Plus i glad I always have about 5 other projects on can work on when I get stuck.

The problem occurs in the saveBitmap method. For that reason the path is null and then a NPE is thrown. Check your code to save the bitmap.

[Q] what the correct way to use ShowcaseView?

when I try to use ShowcaseView I get error
Code:
@override
public void onActivityCreated(Bundle savedInstanceState) {
super.onActivityCreated(savedInstanceState);
final ImageButton saveButton = (ImageButton) view.findViewById(R.id.button_Save);
ViewTarget viewTarget = new ViewTarget(saveButton);
showcaseView = new ShowcaseView.Builder(getActivity())

}
when I tried to do the same thing in my fragmentactivity and didn't work, but when I did the same thing but took a view that declared in the fragmentactivity and not in the fragment it worked.

I understand what the error said but how can I fix it?

[Q] New Dev trying to figure out what is probably a simple problem

I am getting a NullPointerException after the build but once my phone tries to launch the app. I do not understand where the problem is. Im just learning to code and this app is simply supposed to make a toast pop up Long if the checkbox is clicked and short if it isnt.
Code:
package universaltruth.toastee;
import android.support.v7.app.ActionBarActivity;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuItem;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.CheckBox;
import android.widget.EditText;
import android.widget.Toast;
public class MainActivity extends ActionBarActivity {
public CheckBox longToast = (CheckBox) findViewById(R.id.checkbox);
public EditText editText = (EditText) findViewById(R.id.toastText);
public int toastLength = 0;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
addListenerOnlongToast();
}
public void addListenerOnlongToast(){
longToast.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View view) {
if(((CheckBox) view).isChecked()){
toastLength = '1';
}
}
});
}
public void toastMessage(View view){
String message = editText.getText().toString();
Toast.makeText(getApplicationContext(),message, (toastLength == 0) ? Toast.LENGTH_SHORT : Toast.LENGTH_LONG).show();
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.menu_main, menu);
return true;
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle action bar item clicks here. The action bar will
// automatically handle clicks on the Home/Up button, so long
// as you specify a parent activity in AndroidManifest.xml.
int id = item.getItemId();
//noinspection SimplifiableIfStatement
if (id == R.id.action_settings) {
return true;
}
return super.onOptionsItemSelected(item);
}
}

Forgive me if I am not posting this correctly. This is my first time. I am open to any and all feedback. Thank you.

Your problem is that you initialize the longToast checkbox outside of a method. But findViewById only returns a result if called after a call to setContentView(...), which is done in onCreate. So: put your initialization code into onCreate, after setContentView and it will work fine

Hey Masrepus,
Thanks a bunch for answering me.
I have moved the initializations to the on create after the setContentView. I am still getting the null pointer exception. Do you have any further advice?
