Hi guys,
First of all i`m completly noob on this so don`t be much hard with me
ok. i`m trying to develop a simple app just to run 4 simple command to install another app but for now the only thing that i can get to work was asking for su permissions...
can someone help me with this?
Thks a lot
HTML:
try {
runtime.exec("su -c busybox mount -o rw,remount /system");
runtime.exec("cp /sdcard/gscript/xrecovery.sh /data/local/tmp/xrecovery.sh");
runtime.exec("chmod 777 /data/local/tmp/xrecovery.sh");
runtime.exec("/data/local/tmp/xrecovery.sh");
runtime.exec("reboot");
}
catch (IOException e) {
e.printStackTrace();
do not think anyone has the knowledge to help me: .- (
My intention is to create a simple program that installs a file which is in sh sdcard,
"sdcard / gscript / xrecovery.sh"
until now could only be granted access to the root but do not know where and what command should I put to run that sh file...
is that no one can / want help?

You should be able to execute a .sh file by using:
Code:
sh xrecovery.sh

Without sdcard path! ?
And where should i put?

Of course you need to specify the path (it cannot guess where your script is, unless you add it to your PATH). So I guess the following should work for you:
Code:
Runtime.getRuntime().exec("sh /sdcard/gscript/xrecovery.sh");
Unfortunely i cant make this work UK sure that im putting the command Sony the wrong place. I've allready try put Sony a different pplaces but never work: (

So in my toolkit, id like to design an activity where I could point it towards certain lines in the build.prop to allow a user to easily toggle, for instance this line
qemu.hw.mainkeys=0
So, in the layout xml, lets say it had "Enable Nav Bar" and a "Toggle Button" for on/off
Where would i start in developing such a feature?
You create a ToggleButton and whenever it is clicked, you change the line.
What is your problem?

My concerns are wouldnt I need to add ro permissions on the prop before toggling and a reboot action to apply
I think your device needs to be rooted to be able to write to the build.prop file. You do not need root access to read it though
I'm from mobile and i can't post some code but i will give you some hints
To edit build.prop programmatically first you ne ed to be rooted then you can use the shell command "sed" to exchange values. Take a look at AOKP settings source on github and look for density changer class
If you want to import various build properties you can use fileinputstream and read the file line by line then let the app create listview custom items for every line in the file (you need a custom adapter) .
Sorry if this post it's not really useful but i will edit this when at PC

I Wrote something up but I keep getting force closes "Not a java code monkey yet, still learning" and Ill post here what I have when I get to my pc later. Maybe you can see what Im missing or did wrong. What I did is I have a preference screen similiar to AOKP density changer class. What Im going for is a PreferenceList that you click and your values are Enable or Disabled and another preference to reboot to apply settings. Im wanting to allow the user to enable and disable the Navigation Bar by toggling it through the build.prop. If this works, I want to add more toggles custom values like change your phone model, Screen Density, build number, ect; but figured Id start with something simpler first and see if it works.

this is the method you need:
Code:
private void setLcdDensity(int newDensity) {
Helpers.getMount("rw");
new CMDProcessor().su.runWaitFor("busybox sed -i 's|ro.sf.lcd_density=.*|"
+ "ro.sf.lcd_density" + "=" + newDensity + "|' " + "/system/build.prop");
Helpers.getMount("ro");
}
( method took from here : https://github.com/TeamBAKED/packag...aked/romcontrol/fragments/DensityChanger.java )
newDensity is the int/string you let the user set ( you can use a seekbar or a dialog or what you prefer)
you have also CMDProcessor().su.runWaitFor : just use the classes you can find here : https://github.com/TeamBAKED/packag...11bca71808c9143/src/com/baked/romcontrol/util
just add these classes in your project ( these are to simplify your life when you need to use android terminal [ remember to give credits on your app! ] )
Now, you can use various types of views and methods to show to the user all the available props:
- manually add every view for every line in your build.prop ( this will probably limit the compatibility with other devices and make your app "laggy" due to "gazilions" views )
- use a blank linearLayout and inflate a "row view" for every line in build.prop:
read file line by line and import every line in an ArrayList:
Code:
ArrayList<String> Tokens = new ArrayList<String>();
try {
// Open the file that is the first
// command line parameter
FileInputStream fstream = new FileInputStream("/system/build.prop");
// Get the object of DataInputStream
DataInputStream in = new DataInputStream(fstream);
BufferedReader br = new BufferedReader(new InputStreamReader(in));
String strLine;
// Read File Line By Line
while ((strLine = br.readLine()) != null) {
strLine = strLine.trim();
if ((strLine.length()!=0)) {
String[] names = strLine.split("\\s+");
Tokens.add(names[0]);
}
}
for (String s : Tokens) {
//System.out.println(s);
//Log.d("NNNNNNNNNNNNNNNNNN", s);
}
// Close the input stream
in.close();
} catch (Exception e) {// Catch exception if any
System.err.println("Error: " + e.getMessage());
}
names = new String[Tokens.size()-1];
names = Tokens.toArray(names);
ArrayList<String> value = new ArrayList<String>();
try {
// Open the file that is the first
// command line parameter
FileInputStream fstream = new FileInputStream("/sys/devices/system/cpu/cpu0/cpufreq/UV_mV_table");
// Get the object of DataInputStream
DataInputStream in = new DataInputStream(fstream);
BufferedReader br = new BufferedReader(new InputStreamReader(in));
String strLine;
// Read File Line By Line
while ((strLine = br.readLine()) != null) {
strLine = strLine.trim();
if ((strLine.length()!=0)) {
String[] val = strLine.split("\\s+");
value.add(val[1]);
}
}
for (String s : value) {
//System.out.println(s);
//Log.d("NNNNNNNNNNNNNNNNNN", s);
}
// Close the input stream
in.close();
} catch (Exception e) {// Catch exception if any
System.err.println("Error: " + e.getMessage());
}
values = new String[value.size()-1];
values = value.toArray(values);
LineNumberReader lnr = null;
try {
lnr = new LineNumberReader(new FileReader(new File("/sys/devices/system/cpu/cpu0/cpufreq/UV_mV_table")));
} catch (FileNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
try {
lnr.skip(Long.MAX_VALUE);
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
int num = lnr.getLineNumber();
Log.d("LINES", ""+num);
int i = 0;
//now inflate a specific view for every line
// you can also filter every item for example by reading the string and inflating a different layout using an if statement
for (String s : names) {
LayoutInflater inflater = (LayoutInflater)this.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
final View v = inflater.inflate(R.layout.uvrow, null, true);
TextView text0 = (TextView) v.findViewById(R.id.text0);
ImageButton back0 = (ImageButton) v.findViewById(R.id.back0);
final EditText edit0 = (EditText) v.findViewById(R.id.edit0);
ImageButton fwd0 = (ImageButton) v.findViewById(R.id.fwd0);
text0.setText(s);
parentGroup.addView(v);
edit0.setText(values[i]);
/*
* if you need to set listeners and actions insert them inside this loop!
*/
}

please post the Log you get on Eclipse !
the log will tell you exactly where the error is
Currently, i'm making an application that involves using GestureOverlayView. I've already created some default gestures using the GestureBuilder and have copied them into my res/raw folder in my application. My application also does customization, meaning that the user can create his or her own gestures and save them. I've read that it's impossible for me to just save the additionally made gestures from the users to the res/raw folder. I was told that i have some optionals: ExternalStorage (to SD card), InternalStorage, and SharedPreferences. Which method is probably the more optimal choice?
I've tried using these codes:
gestureLib.addGesture(scName.getText().toString(), gesture);
gestureLib.save();
setResult(RESULT_OK);
in an attempt to save them. Even though the gestures do save, but when i restart the application, they're gone. Please help! Thanks so much!

I haven't used gestures so far but for the saving:
In your SharedPreferences you can only save the standard types like int or string. I'm guessing you don't want to convert the gesture to string and backwards, so I'd say external storage in a folder with the name of your app(so the user can manually delete it) but you could also save the file in your app directory.
Look at This question , he uses the gesture library and saves it to the file with
Code:
GestureLibrary store = GestureLibraries.fromFile(mStoreFile);
store.addGesture("Gesture Password", mGesture);
store.save();
My application successfully saves now, but there's still a consistent problem. When i restart the application, the saved gestures are gone. Why is that?

When you restart your app, everything in its ram will be gone, so you always need to load the saved file and then import the gestures to the library again probably.
You'd want to do that in the onCreate() or onRestart().
In the above example,
Code:
store.load();
Is used to do that
It works now. Thanks a lot. I'm assuming that these gestures are being saved in the application itself, since that i can't find them in the SD card. Thanks for your time, by the way.

BUMP! I've been struggling with a problem that i newly encountered. What i want to do is, i want to create a folder in the external directory and save ALL the gestures that the user creates. But the thing is, every time i save the gesture, it overwrites the existing one. How do i create a folder and put the new ones in it? Any help or hints would be nice

You've got to use a different string for every gesture in that line:
Code:
store.addGesture("this should be a different string every time", mGesture);
Then you should be able to put them into one file.

As you can see, i have every gesture named after its own unique scName (EditText).
What's happening right now is that i successfully creates a folder name "com.epicunlock.rx24race" inside Android/data, but nothing is ever saved in it

As far as I know the file you save it to mustn't be a directory, but a file.
Try that:
Code:
mStoreFile = new File(Environment.getExternalStorageDirectory().getAbsolutePath() + "/Android/data/com.epicunlock.rx24race");
if (!mStoreFile.exists()) {
mStoreFile.mkdirs();
}
[COLOR="Red"]File gestureFile = new File(mStoreFile, "gestures");
lib = GestureLibraries.fromFile(gestureFile);[/COLOR]
lib.load();
and
Code:
if (!found) {
Log.v("TAG", "Gesture has been saved");
Toast.makeText(this, "Saved", Toast.LENGTH_SHORT).show();
[COLOR="Red"]File gestureFile = new File(mStoreFile, "gestures");
lib = GestureLibraries.fromFile(gestureFile);[/COLOR]
lib.addGesture(scName.getText().toString(), gesture);
lib.save();
setResult(RESULT_OK);
}

I've tried something similar to this before too, but the same problem still exists. it keeps overwriting the previous one. It's never able to save multiple gestures.
What i have:
Code:
package com.epicunlock.rx24race;
import java.io.File;
import java.util.ArrayList;
import android.app.Activity;
import android.gesture.Gesture;
import android.gesture.GestureLibraries;
import android.gesture.GestureLibrary;
import android.gesture.GestureOverlayView;
import android.gesture.GestureOverlayView.OnGesturePerformedListener;
import android.gesture.Prediction;
import android.os.Bundle;
import android.os.Environment;
import android.util.Log;
import android.widget.EditText;
import android.widget.Toast;
public class createShortcut extends Activity implements
OnGesturePerformedListener {
boolean found = false;
EditText scName;
GestureOverlayView gestures;
GestureLibrary lib, storage;
File path;
[user=439709]@override[/user]
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.createshortcutlayout);
scName = (EditText) findViewById(R.id.etName);
gestures = (GestureOverlayView) findViewById(R.id.gestures);
gestures.addOnGesturePerformedListener(this);
path = new File(Environment.getExternalStorageDirectory() + "/Android/data/com.epicunlock.rx24race/");
if (!path.exists()) {
path.mkdirs();
}
File gestureFile = new File(path, "gestures");
lib = GestureLibraries.fromFile(gestureFile);
lib.load();
}
[user=439709]@override[/user]
public void onGesturePerformed(GestureOverlayView overlay, Gesture gesture) {
// TODO Auto-generated method stub
found = false;
ArrayList<Prediction> predictions = lib.recognize(gesture);
for (String s : lib.getGestureEntries()) {
Log.v("GESTURE", s);
}
Log.v("TAG", "Gesture has been detected");
for (Prediction p : predictions) {
Log.v("TAG", p.toString());
Log.v("^ Score", "" + p.score);
}
for (Prediction p : predictions) {
if (p.score > 2.0) {
Toast.makeText(this, p.name, Toast.LENGTH_SHORT).show();
found = true;
}
}
if (!found) {
Log.v("TAG", "Gesture has been saved");
Toast.makeText(this, "Saved", Toast.LENGTH_SHORT).show();
File gestureFile = new File(path, "gestures");
lib = GestureLibraries.fromFile(gestureFile);
lib.addGesture(scName.getText().toString(), gesture);
lib.save();
setResult(RESULT_OK);
}
}
}
I just fixed the problem: "Can't save multiple gestures."
This is how i fixed it. But can anyone tell me what difference it made?
Code:
[user=439709]@override[/user]
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.createshortcutlayout);
scName = (EditText) findViewById(R.id.etName);
gestures = (GestureOverlayView) findViewById(R.id.gestures);
gestures.addOnGesturePerformedListener(this);
path = new File(Environment.getExternalStorageDirectory() + "/Android/data/com.epicunlock.rx24race/");
if (!path.exists()) {
path.mkdirs();
}
[B]if (lib == null) {
gestureFile = new File(path, "gestures");
lib = GestureLibraries.fromFile(gestureFile);
}[/B]
lib.load();
}
Moderators... It says I am breaking the rules by asking a question and to ask in the Q&A... But the title of this is "Coding Discussion, Q&A, and Educational Resources" I am not breaking the rules intentionally, I just don't know where else to put this. This is a Coding Question, not a General Question that I would think would get buried and or lost in the General Q&A forum. Please move if you feel I am incorrect.
Hello All, I was hoping someone could help me.
I am trying to create an app that will hide pictures. I want to be able to Pick my App from the Share (Send To) menu from the Users Gallery and have it copy the file to a Directory I have created on my SDCard and then ultimately delete the file from the current location.
Here is what I have so far, but when I pick my app from the Share menu, it crashes the Gallery app. So... I can't even see any errors in my LogCat to even try and troubleshoot my issue.
Can someone point me to a working example of how to do this (I have searched the internet until I am blue in the face) or... I hate to say it... Fix my Code?
Any Help would be appreciated... Thanks!!

What's the gallery log output?
Btw, you're not breaking the rules. This is the right forum for Java Q&A.

How would I get the Logs for the Gallery? I am using and HTC ONE and it's the standard Gallery. Nothing shows up in LogCat so I'm stuck

Do you view the logs on your computer?
There should be an error message in the logs.

Which Logs?? As I said before. LogCat does not give any errors.
I'm trying to make an app that displays and image which will be downloaded in background in an IntentService class. When the IntentService finishes to download it sends the intent to be catched by a BroadcastReceiver in the MainActivity but I'm getting this error:

What am I doing wrong?
Code:

tells you there, you are asking an object that is of type "x" that is NULL to do something on line 74
Why not just use the picasso library or similar to download the image asynchronously in the background?

I'm a beginner in Android application so I don't have the proper knowledge right now, thanks for the suggestion though, I'll definitely try to take a look at that library :good:

Yeah but I also need to download it and then load it, and it's not good to download that amount of data on the main thread

AsyncTask runs in the background on a separate thread via the doInBackground method.

Also, when there is a possibility that one of the objects included in the intent is null you can trap the error with a try/catch around the sendBroadcast() to prevent the exception from crashing the entire app.
