How to resume MediaPlayer in Android after pressing the home button and reopen the app

I tried a lot of methods, I made a lot of changes on my code, I read Android MediaPlayer document, I tried StackOverflow examples but none of them could solve my problem.

I understand you have accepted an answer but I'll explain what the problem was based on your comments on your question and the comments from you and Nana on Nana's answer.
A SurfaceView is destroyed when it is no longer visible and recreated when it becomes visible again.
You are calling mp.pause() in your Activity onPause() method.
When you go to the 'recent' apps list and attempt to restart the app, the SurfaceView is recreated.
In surfaceCreated method you are calling mp.prepare() but at this point mp is in a paused state and calling prepare() on a paused Mediaplayer will throw an IllegalStateException.
You have a try / catch block which catches IllegalStateException and calls finish() - this is why the first attempt to restart the app from the 'recent' list causes the the Activity to be destroyed.
As a result of the above sequence of events you need a second attempt to re-open the app from the 'recent' list but as the Activity has been destroyed it will go through a full creation (with onCreate(..) being called. This is why it starts from the beginning.
The answer from Nana is a workaround but it will still mean having to use two attempts to restart your Activity from the 'recent' list.
Unfortunately the MediaPlayer class is lacking in methods for checking the 'state' with isPlaying being the only useful method for any state. It's a shame the class devs didn't think to add a getState() method (or similar) to allow checking for whether it's started, playing, stopped, paused etc.
One way of preventing the IllegalStateException would be to have a boolean called isPaused (for example) then modify your Activity onPause() as follows...
if (mediaPlayer.isPlaying()) {
mediaPlayer.pause();
isPaused = true;
}
...and in surfaceCreated(...)...
try {
if (isPaused) {
mpStart();
isPaused = false;
}
else
mediaPlayer.prepare();
}
// catch blocks here

The activity is being restarted thereby triggering surfaceCreated() and mediaPlayer.prepare(), which in turns calls onPrepared and mp.start() to restart the track. You have no mechanism to resume playing. Do this - Get the last position of the track when paused(HOME button is pressed), then when the activity is "recreated" resume playing the track by seeking to that last position. Modify your onPause() and onPrepared() as follows:
int length = 0;
//save last position when activity is paused
#Override
protected void onPause() {
super.onPause();
if (mediaPlayer.isPlaying()) {
mediaPlayer.pause();
length = mediaPlayer.getCurrentPosition();
} else {
return;
}
}
public void onPrepared(MediaPlayer mp) {
........
.........
.........
mp.start();
//seek to saved position.
mp.seekTo(length);
}

Asynchronous Video Streaming Android

I have been working on video playback of progressive videos from my android application. I am able to stream videos from internet.
But the video starts after buffering the whole data.
Here is the code I am using-
private static final String MOVIEURL = "movieUrl";
private static final String TAG = "VideoPlayerActivity";
private int mVideoWidth;
private int mVideoHeight;
private MediaPlayer mMediaPlayer;
private SurfaceView mPreview;
private SurfaceHolder holder;
private String path;
private Bundle extras;
private boolean mIsVideoSizeKnown = false;
private boolean mIsVideoReadyToBePlayed = false;
protected void onCreate(Bundle icicle) {
super.onCreate(icicle);
setContentView(R.layout.mediaplayer_2);
mPreview = (SurfaceView) findViewById(R.id.surface);
holder = mPreview.getHolder();
holder.addCallback(this);
holder.setType(SurfaceHolder.SURFACE_TYPE_PUSH_BUFFERS);
extras = getIntent().getExtras();
}
private void playVideo(String movieUrl) {
doCleanUp();
try {
path=movieUrl;
// Create a new media player and set the listeners
mMediaPlayer = new MediaPlayer();
mMediaPlayer.setDataSource(path);
mMediaPlayer.setDisplay(holder);
mMediaPlayer.prepare();
mMediaPlayer.setOnBufferingUpdateListener(this);
mMediaPlayer.setOnCompletionListener(this);
mMediaPlayer.setOnPreparedListener(this);
mMediaPlayer.setOnVideoSizeChangedListener(this);
mMediaPlayer.setAudioStreamType(AudioManager.STREAM_MUSIC);
} catch (Exception e) {
Log.e(TAG, "error: " + e.getMessage(), e);
return false;
}
}
public void onBufferingUpdate(MediaPlayer arg0, int percent) {
Log.d(TAG, "onBufferingUpdate percent:" + percent);
}
public void onCompletion(MediaPlayer arg0) {
Log.d(TAG, "onCompletion called");
}
private void doCleanUp() {
mVideoWidth = 0;
mVideoHeight = 0;
mIsVideoReadyToBePlayed = false;
mIsVideoSizeKnown = false;
}
public void onVideoSizeChanged(MediaPlayer mp, int width, int height) {
Log.v(TAG, "onVideoSizeChanged called");
if (width == 0 || height == 0) {
Log.e(TAG, "invalid video width(" + width + ") or height(" + height + ")");
return;
}
mIsVideoSizeKnown = true;
mVideoWidth = width;
mVideoHeight = height;
if (mIsVideoReadyToBePlayed && mIsVideoSizeKnown) {
startVideoPlayback();
}
}
public void onPrepared(MediaPlayer mediaplayer) {
Log.d(TAG, "onPrepared called");
mIsVideoReadyToBePlayed = true;
if (mIsVideoReadyToBePlayed && mIsVideoSizeKnown) {
startVideoPlayback();
}
}
public void surfaceChanged(SurfaceHolder surfaceholder, int i, int j, int k) {
Log.d(TAG, "surfaceChanged called");
}
public void surfaceDestroyed(SurfaceHolder surfaceholder) {
Log.d(TAG, "surfaceDestroyed called");
}
public void surfaceCreated(SurfaceHolder holder) {
Log.d(TAG, "surfaceCreated called");
playVideo(extras.getString(MOVIEURL));
}
#Override
protected void onPause() {
super.onPause();
releaseMediaPlayer();
doCleanUp();
}
#Override
protected void onDestroy() {
super.onDestroy();
releaseMediaPlayer();
doCleanUp();
}
private void releaseMediaPlayer() {
if (mMediaPlayer != null) {
mMediaPlayer.release();
mMediaPlayer = null;
}
}
private void startVideoPlayback() {
Log.v(TAG, "startVideoPlayback");
holder.setFixedSize(mVideoWidth, mVideoHeight);
mMediaPlayer.start();
}
This code is working fine, but not playing before the whole video gets buffered.
Is there anyway we can stream the video while buffering it in the background.
Thanks.

Instead of
mMediaPlayer.prepare();
Use :
mMediaPlayer.prepareAsync();

This is the code i tried to run.

I fixed this problem by changing the project build target from Android 1.6 to Android 4.2 in Project Property/*Android*.
Some new syntax in layout xml files are not supported in old version but these error information is not display in the source code but in the output window.

This can have several causes.
Make sure that you don't have any XML errors in all your files. The R. file will not be built when you have XML errors. After you fixed the errors the R. file should be built automatically. If not, try cleaning your project.
Also, make sure you do not have this line:
import android.R;
in your class.

That implies errors on the layout or Manifest file , which are XML .
I think the common mistakes can be the error of layout design , missing tags , and so on
please Fix them first and clean the project again
