[Q] Android RSS FEED Reader issues

I want to developer RSS FEED reader for android. I am following this tutorial : http://www.ibm.com/developerworks/xml/tutorials/x-androidrss/downloads.html
I am not getting any error in the program but not getting desired output
**This is my logcat:**

**HELP!!!**

I found the IBM tutorial very hard to follow, I eventually read RSS through a simpler way. Here is a link to the tutorial I wrote after:
http://droidapp.co.uk/?p=166

Thanks, could you plz upload the full source code ?
Does it support images and clickable feed so that clicking any feed directs the user to the website ?

I will upload the full source of my app today.
It will read any section of the xml so if there are images you will be able to extract the URL and use it in your app. It does support clickable feed also, just by extracting the post URL again.
The app I made is for an audio podcast.

Here you go... hope it helps

hello tony,
first thank you for the source code.
I tried running your source code but I am getting these error messages:
Code:
Description Resource Path Location Type
Project 'EppyGibbonPodcast' is missing required library: 'C:\Users\Tony.DZNT\AndroidDev\android-sdk-windows\extras\android\compatibility\v4\android-support-v4.jar' EppyGibbonPodcast Build path Build Path Problem
The project cannot be built until build path errors are resolved EppyGibbonPodcast Unknown Java Problem
Attribute minSdkVersion (4) is lower than the project target API level (10) AndroidManifest.xml /EppyGibbonPodcast line 1 Android ADT Problem
This is the version of my eclipse:
Code:
Eclipse IDE for Java Developers
Version: Helios Service Release 2
Build id: 20110218-0911
I am using 2.2 but I can see you created this code for 2.3. I do have API installed for 3.0 and 3.1 etc so I should be at-least able to run the program on virtual mobile (on PC thru eclipse) but getting the above error msgs.
Please Help.

I just found the file "android-support-v4.jar" in this location:
D:\Android\AndroidSDK\android-sdk-windows\extras\android\compatibility\v4
now how and where I can link this path ?

Sorry, I must have left that in from when I was playing with Fragments, it's not needed. You can remove it from the build path. Right click the project, properties, then find and remove from build path.

Hi tony,
I did try to remove it and now I am getting these errors:

I would deeply appreciate if you could upload a fresh copy of source code without this fragment file / issue.
thank you

OK. I'll upload again tomorrow.

thanks i will keep an eye on your site and here

I have re-uploaded the source, now without the Fragment compatability.

Let me know if you have any problems, but this should run fine now.

it does work now.

I tested the code and I think it only works for the RSS FEED that you added in the code.
I tried other rss feed like "http://rss.news.yahoo.com/rss/mostviewed" mentioned on your website (in comments) and few other rss feeds but nothing seems to be working.
(thanks once for all the help)

I wouldn't worry about those warnings.
The app I have uploaded is specifically for the Epileptic Gibbon Podcast, which is a wordpress site.
The code should just need slight changes to match the rss feed you want to use. I suggest you download the rss xml for Epileptic Gibbon and the rss xml for Yahoo and compare the differences.

really great code.
Thanks.

I could really use some help.
I would like to use this app to pull feeds for this site.

But have no idea how to add this to eclipse and then turn it in to an app.
Could someone help out with the steps to take?
Thank.

[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:

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

</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
}
}

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 does:

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){

Camera Preview

Im trying to start a simple app and i need to display on a SurfaceView the preview of the cam as soon as the App start.
i added the permission to the manifest:
<uses-permission android:name="android.permission.CAMERA" />
<uses-feature android:name="android.hardware.camera" />
and my code:
Code:
import android.content.Context;
import android.hardware.Camera;
import android.view.SurfaceHolder;
import android.view.SurfaceView;
public class MainActivity extends SurfaceView implements SurfaceHolder.Callback{
SurfaceView mSurfaceView;
private SurfaceHolder mHolder;
public Camera camera = null;
public MainActivity(Context context) {
super(context);
mSurfaceView = (SurfaceView) findViewById(R.id.surfaceView);
mHolder = mSurfaceView.getHolder();
mHolder.addCallback(this);
mHolder.setType(SurfaceHolder.SURFACE_TYPE_PUSH_BUFFERS);
}
[user=439709]@override[/user]
public void surfaceCreated(SurfaceHolder holder) {
camera = Camera.open();
try{
camera.setPreviewDisplay(mHolder);
} catch(Exception e){
}
}
[user=439709]@override[/user]
public void surfaceChanged(SurfaceHolder holder, int format, int width, int height) {
Camera.Parameters params = camera.getParameters();
params.setPreviewSize(width,height);
camera.setParameters(params);
camera.startPreview();
}
[user=439709]@override[/user]
public void surfaceDestroyed(SurfaceHolder holder) {
camera.stopPreview();
camera = null;
}
}
Ive looked for many tutorial and all technically do the same or smiliart stuff. But the app crashes. I cant find a solution

On Eclipse i know how to show the windows of the LogCat, but cant really find it here on Android Studio.
Im a bit newby about this sorry, coming from PHP using just Notepad.
Guess i found it, added log cat
I saw some tutorial like this, im not sure why it doesnt start.
Is it for te onCreate method missing? but i saw that for other works anyway like this
Btw i've also triyed an other way, but stills give me errors. i could upload that one too, different logcat.
Hope one of the two could be solved

In Android you normally do not use the constructor of an Activity for anything.
Use the onCreate method instead.
EDIT: The log says that the constructor must be empty.

I thought about that (even if i saw video tutorial doing it) so i tried wht onCreate method and now it seams to give problem with the setParameters?
Ive uploaded the new code and logcats before

Ah. Check this: http://stackoverflow.com/questions/3890381/camera-setparameters-failed-in-android

i tryed that at th beggin, and didnt work, in fact i tried it again and still give me the same error apparently

While I'm still learning myself, it looks like you are getting a failed camera permission. And then it tries to pass in an invalid parameter to the camera.

But cant understand which one and how should i do. it ryed the 2 ways everybody does

What phone are you trying this on? Have you tried it in an emulator?

After getting home and I was able to try your second piece of code. It looks like it is a problem with <CODE>params.setPreviewSize(arg2, arg3);</CODE>, it doesn't like the width and height arguments. I found THIS(second answer). and after plugging it into your code it was working for me. If you like I can show you the modified code, altho its real easy to plug in.

i tryed his first example and finally i get his "distoted" image. When i'll have time ill try the rets thnk u very much
ill try this:
Code:
Camera.Size getBestPreviewSize(int width, int height, Camera.Parameters parameters) {
Camera.Size result=null;
float dr = Float.MAX_VALUE;
float ratio = (float)width/(float)height;
for (Camera.Size size : parameters.getSupportedPreviewSizes()) {
float r = (float)size.width/(float)size.height;
if( Math.abs(r - ratio) < dr && size.width <= width && size.height <= height ) {
dr = Math.abs(r - ratio);
result = size;
}
}
return result;
}
Code:
ublic void surfaceChanged(SurfaceHolder holder, int format, int w, int h) {
// Now that the size is known, set up the camera parameters and begin
// the preview.
if (isPreviewRunning) {
mCamera.stopPreview();
}
Camera.Parameters parameters = mCamera.getParameters();
List<Size> sizes = parameters.getSupportedPreviewSizes();
Size optimalSize = getBestPreviewSize( w, h, parameters);
parameters.setPreviewSize(optimalSize.width, optimalSize.height);
mCamera.setParameters(parameters);
mCamera.startPreview();
isPreviewRunning =true;
}
im not sure abot the 3rd parameter of the getBestPreviewSize method which one is it. Like this is still distorted

Yeah, I could never fix the distortion back when I was trying my camera app. But I think I will tinker with it again. Keep this updated if you find anything, I will also.

Can anyone help me troubleshoot some bluetooth audio skipping? (logcat included)

So I have a Razr M running a deodexed stock rom, on the stock kernel. I am paired to a pair of Motorola S11 Flex HD. Whenever I use Poweramp or PocketCasts, I get audio skipping at the beginning of songs, when I open a menu, or when I poer off the screen. I thought it was my arrghh kernel, but it turns out the issue returned on the stock kernel as well.
here is a log cat, started as soon as I powered on the headphones, through pairing, when the audio skips, and then ended when the audio evens out:

Here's my Code.
Code:
public class DatabaseHandler extends SQLiteOpenHelper {
// All Static variables
// Database Version
private static final int DATABASE_VERSION = 1;
// Database Name
private static final String DATABASE_NAME = "timetable";
// Bus table name
static final String TABLE_PNOTOCDM = "pnotocdm";
// Bus Table Columns names
private static final String KEY_ID = "id";
private static final String KEY_BUSNAME = "busname";
private static final String KEY_TIME = "time";
...
public List<Pnotocdm> getAllBus() {
List<Pnotocdm> busList = new ArrayList<Pnotocdm>();
// Select All Query
String selectQuery = " SELECT * " + TABLE_PNOTOCDM + " where KEY_TIME = ? " ;
SQLiteDatabase db = this.getWritableDatabase();
Calendar cal = Calendar.getInstance();
int minute = cal.get(Calendar.MINUTE);
int hour = cal.get(Calendar.HOUR);
String time = String.valueOf(hour)+String.valueOf(minute);
Cursor cursor = db.rawQuery(selectQuery, new String[] {time});
// looping through all rows and adding to list
if (cursor.moveToFirst()) {
do {
Pnotocdm bus = new Pnotocdm();
bus.setID(Integer.parseInt(cursor.getString(0)));
bus.setBusName(cursor.getString(1));
bus.setTime(cursor.getString(2));
String name = cursor.getString(1) +"\n"+ cursor.getString(2);
Third.ArrayofName.add(name);
// Adding bus to list
busList.add(bus);
} while (cursor.moveToNext());
}
// return bus list
return busList;
}
I Know the rawquery is wrong but i dont know the Correct Query.
What I Intended is this, The System should compute the Current Time and Check with time Column in the table and Return those values which are greater than the current Time.
The Correct Query Which works in sqlite Browser is
Code:
SELECT busname,time FROM pnotocdm WHERE time>time('now','localtime');
But I dont know how to convert that sql query into java rawquery() method. Please Help

Important questions first :
What error do you get ? like a NullPointerException or a CursorIndexOutOfBounds etc.
A standard sql syntax for a query would be
SELECT "Column Name" FROM "TABLE NAME" WHERE "your column" = "desired value" I cant say a word more on the query because i dont know what the variables TABLE_PNOTOCDM and KEY_TIME represent
A structure of your table could make things easier
I think u meant
Code:
String time = String.valueOf(hour)+String.valueOf(minute);
instead of
String time = String.valueOf(minute)+String.valueOf(hour);
and if can spare some time please read http://forum.xda-developers.com/showthread.php?t=2439748

looks like a syntax error in your raw query
SELECT "Column Name" FROM "TABLE NAME" WHERE "your column" = "desired value"

No dude your SQL syntax is not correct it should look like
String selectQuery = " SELECT * FROM "+TABLE_PNOTOCDM + " WHERE "+KEY_TIME+" = ? " ;

Yes... Thanks...Thats the mistake.. Now the Query is running without any crashes/error. But i dont get the Result i am expecting. I want the rows which is greater than the current time. how to achieve this ?
Code:
SELECT * FROM pnotocdm WHERE time > time('now','localtime');
I want the java query equivalent to the above sql query. Any Help ?

I think you should firstly check your query in sql then use here.
And your loop maybe the problem.i used like this
while(cursor.moveToNext()){
//get your values
}

I got another problem.
Here's what I'm trying to do,
1. Launch Activity A, Press Button Goto Activity B, Press Button Goto Activity C.
2. Press back button goto Activity B (Activity C is not paused but destroyed)
3. Press button and goto Activity C now again onCreate method is called and activity C is created again.
So why is this happening to my app. I want the activities to pause. How to achieve this?
Thanks in advance.
