Mediaplayer stops working after clicking 14 times

I'm building app which make tic sound on clicking the button. But the sound stops after clicking 14 time. The code is here:
dTextVeiw.setOnClickListener(new View.onClickListener() {
#Override
public void onClick(View view){
MediaPlayer mediaPlayer = MediaPlayer.create(getApplicationContext(), R.raw.tic_sound);
mediaPlayer.setAudioStreamType(AudioManager.STREAM_MUSIC);
mediaPlayer.start();
}
});

No need to initialise it every time you click the button.
private MediaPlayer _mediaPlayer;
#Override
protected void onResume()
{
super.onResume();
_mediaPlayer = MediaPlayer.create(getApplicationContext(), R.raw.tic_sound);
_mediaPlayer.setAudioStreamType(AudioManager.STREAM_MUSIC);
}
#Override
protected void onCreate(#Nullable Bundle savedInstanceState)
{
//...
dTextVeiw.setOnClickListener(new View.onClickListener() {
#Override
public void onClick(View view) {
_mediaPlayer.start();
}
});
}

For short sounds i would recommend using SoundPool
Class SoundPlayer(){
private final static float leftVol = 1.0f;
private final static float rightVol = 1.0f;
private final static float rate = 1.0f;
private final static int loop = 0;
private int priority = 1;
private int audioId = = -1;
AudioAttributes attributes = new AudioAttributes.Builder()
.setUsage(AudioAttributes.USAGE_GAME)
.setContentType(AudioAttributes.CONTENT_TYPE_SONIFICATION)
.build();
SoundPool soundPool= new SoundPool.Builder()
.setMaxStreams(2)
.setAudioAttributes(attributes)
.build();
public void loadSounds(Context context){
audioId = soundPool.load(context, R.raw.tic_sound, priority);
}
public void playAudio() {
soundPool.play(audioId, leftVol, rightVol, priority, loop, rate) ;
}
}
And use it like this
private SoundPlayer soundPlayer;
....
....
onCreate ...{
soundPlayer = SoundPlayer();
soundPLayer.loadSounds(this);
dTextVeiw.setOnClickListener(new View.onClickListener() {
#Override
public void onClick(View view){
soundPLayer.playAudio();
}

Android VideoView buffering

I'm working on the Android TV app which uses VideoView to play the video from the url. Each time the video is paused and then resumed - it takes some time to pre-download it first (few seconds during which progress bar appears). The goal is to buffer the video during playback so that when I pause it and then resume - it resumes from pre-buffered state immediately without delay. I've also tried videoView.resume() method, but it doesn't help either. Is there a way to do that or am I doing something wrong?
Here is the code which plays/resumes the video:
public void onFragmentPlayPause(final Video video,
final VideoQuality quality,
final int position,
final Boolean play) {
stopSeeking();
videoView.setVideoPath(video.videoUrl(quality));
if (position == 0 || playbackState == LeanbackPlaybackState.IDLE) {
setupCallbacks();
playbackState = LeanbackPlaybackState.IDLE;
}
if (play && playbackState != LeanbackPlaybackState.PLAYING) {
progressBar.setVisibility(View.VISIBLE);
playbackState = LeanbackPlaybackState.PLAYING;
if (position > 0) {
videoView.seekTo(position);
videoView.start();
}
playbackFragment.startProgressObservation(progressFlowable());
} else {
playbackState = LeanbackPlaybackState.PAUSED;
videoView.pause();
playbackFragment.stopProgressObservation();
}
updatePlaybackState(position);
updateMetadata(video);
}

Unfortunately, I've didn't find the way to achieve this with VideoView, only using ExoPlayer, thanks to #pskink for the right direction. The API was returning mp4 videos, so I've used ExtractorMediaSource. The complete demo example with support of multiple formats can be found on ExoPlayer GitHub page.
Here is the final code I've ended up with using ExoPlayer:
private void playPause(final Video video, final int position, final Boolean play) {
if (position == 0 || playbackState == LeanbackPlaybackState.IDLE) {
setupCallbacks();
playbackState = LeanbackPlaybackState.IDLE;
}
if (play && playbackState != LeanbackPlaybackState.PLAYING) {
progressBar.setVisibility(View.VISIBLE);
playbackState = LeanbackPlaybackState.PLAYING;
player.start();
playbackFragment.startProgressObservation(progressFlowable());
} else {
playbackState = LeanbackPlaybackState.PAUSED;
player.pause();
playbackFragment.stopProgressObservation();
}
updatePlaybackState(position);
updateMetadata(video);
}
And Player implementation:

There is a delay when showing webview which loading url is completed at invisible

First, WebView starting load a url at invisible(setVisibility(View.INVISIBLE))on service. and wait until the url loading is done.
finally, set the visibility is show(setVisibility(View.VISIBLE)), the WebView show empty screen(white screen) about 0.5 second. then show rendered web page.
I want to show rendered web page immediately on WebView without empty screen.
like this
public class MainActivity extends Activity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
startService(new Intent(this, ServiceViewManager.class));
setUI();

this.setContentView(layout);
}

{
Button button = new Button(this);
button.setText("LoadUrlInvisible (Click first)");
button.setOnClickListener(new View.OnClickListener() {
#Override

});
return button;
}

Show Text in TextView when video reaches current time Android

I want to make a text appear in TextView when the video reaches current time. I've tried this code :
public class VideoActivity extends Activity {
private static final String MY_AD_UNIT_ID = null;
protected static final String TAG = null;
private AdView adView;
int waktu;
Button btncek;
private MediaController controller = null;
TextView textView2;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.videoplayer);
Bundle bundle = getIntent().getExtras();
String urlbarus = getIntent().getStringExtra("urlbaru");
final VideoView videoView = (VideoView) findViewById(R.id.videoView1);
videoView.setVideoPath(urlbarus);
MediaController.MediaPlayerControl mcEvents = new MediaController.MediaPlayerControl() {
public void start() {
videoView.start();
}
public void seekTo(int pos) {
videoView.seekTo(pos);
}
public void pause() {
videoView.pause();
}
public boolean isPlaying() {
return videoView.isPlaying();
}
public int getDuration() {
return videoView.getDuration();
}
public int getCurrentPosition() {
return videoView.getCurrentPosition();
}
public boolean canSeekForward() {
return true;
}
public boolean canSeekBackward() {
return true;
}
public boolean canPause() {
return true;
}
#Override
public int getBufferPercentage() {
// TODO Auto-generated method stub
return 0;
}
};
controller = new MediaController(this);
controller.setMediaPlayer(mcEvents);
controller.setAnchorView(findViewById(R.id.wrapper));
videoView.start();
if(mcEvents.getCurrentPosition()>=10000){
textView2.setText("kebaca");
}
#Override
public boolean onTouchEvent(MotionEvent event) {
//the MediaController will hide after 3 seconds - tap the screen to make it appear again
controller.show();
return false;
}
This is the code for showing text :
if(mcEvents.getCurrentPosition()>=10000){
textView2.setText("kebaca");
}
I have tried that code, but nothing happens (textview2 does not show the text)
Can anyone help me?

Try something like..
final MediaController.MediaPlayerControl mcEvents = ....
textView2.setText(""); // edited
new Thread(new Runnable() {
#Override
public void run() {
while (mcEvents.getCurrentPosition()<10000){
try {
Thread.sleep(1000);
} catch (InterruptedException ignored) { }
}
runOnUiThread(new Runnable() {
#Override
public void run() {
textView2.setText("kebaca");
}
});
}
}).start();

Playing audio file in android

I got stuck with one requirement i need to play a media file in android.I will post the screen shot of the page
Actual requirement is the user wants to play the audio file in his recordings list.The recordings list are shown through list adapter.I want to display the play progress of the audio file on the same page(as like shown in the screen shot).
Iam pasting the code which i have tried.
public class RecordingActivity extends ListActivity implements MediaPlayerControl {
MediaPlayer mMediaPlayer;
MediaController mMediaController;
Handler mHandler;
String OUTPUT_FILE;
RelativeLayout rl;
Context context = null;
Point p;
static final String[] recordings = new String[] {"Example1","Example2",
"Example3","Example4","Example5" };
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setListAdapter(new FirstAdapter(this, recordings));
}
#Override
protected void onListItemClick(ListView l, View v, int position, long id) {
showPopup(RecordingActivity.this, p);
// get selected items
mMediaPlayer = new MediaPlayer();
mMediaController = new MediaController(this);
mHandler = new Handler();
mMediaController.setMediaPlayer(RecordingActivity.this);
OUTPUT_FILE = Environment.getExternalStorageDirectory()+"/recorder.mp3";
try{
mMediaPlayer.setDataSource(OUTPUT_FILE);
mMediaPlayer.prepare();
}
catch(Exception e){
}
mMediaPlayer.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
#Override
public void onPrepared(MediaPlayer mp) {
mHandler.post(new Runnable() {
public void run() {
mMediaController.show(10000);
mMediaPlayer.start();
mMediaController.setEnabled(true);
}
});
}
});
}
private void showPopup(final Activity context, Point p) {
int popupWidth = 200;
int popupHeight = 150;
// Inflate the popup_layout.xml
RelativeLayout viewGroup = (RelativeLayout) context.findViewById(R.id.reviewlist);
LayoutInflater layoutInflater = (LayoutInflater) context
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View layout = layoutInflater.inflate(R.layout.activity_play, viewGroup);
// Creating the PopupWindow
final PopupWindow popup = new PopupWindow(context);
popup.setContentView(layout);
popup.setWidth(popupWidth);
popup.setHeight(popupHeight);
popup.setFocusable(true);
// Some offset to align the popup a bit to the right, and a bit down, relative to button's position.
int OFFSET_X = 30;
int OFFSET_Y = 30;
// Clear the default translucent background
popup.setBackgroundDrawable(new BitmapDrawable());
// Displaying the popup at the specified location, + offsets.
popup.showAtLocation(layout, Gravity.NO_GRAVITY,p.x+OFFSET_X,p.y+OFFSET_Y);
// Getting a reference to Close button, and close the popup when clicked.
ImageButton close = (ImageButton) layout.findViewById(R.id.close);
Button b1 =(Button) layout.findViewById(R.id.button1);
Button b2 =(Button) layout.findViewById(R.id.button2);
close.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
popup.dismiss();
}
});
}
#Override
protected void onDestroy() {
super.onDestroy();
mMediaPlayer.stop();
mMediaPlayer.release();
}
#Override
public boolean canPause() {
return true;
}
#Override
public boolean canSeekBackward() {
return false;
}
#Override
public boolean canSeekForward() {
return false;
}
#Override
public int getBufferPercentage() {
int percentage = (mMediaPlayer.getCurrentPosition() * 100) / mMediaPlayer.getDuration();
return percentage;
}
#Override
public int getCurrentPosition() {
return mMediaPlayer.getCurrentPosition();
}
#Override
public int getDuration() {
return mMediaPlayer.getDuration();
}
#Override
public boolean isPlaying() {
return mMediaPlayer.isPlaying();
}
#Override
public void pause() {
if(mMediaPlayer.isPlaying())
mMediaPlayer.pause();
}
#Override
public void seekTo(int pos) {
mMediaPlayer.seekTo(pos);
}
#Override
public void start() {
mMediaPlayer.start();
mMediaController.show();
}
#Override
public boolean onTouchEvent(MotionEvent event) {
mMediaController.show();
return false;
}
}
The problem am facing is i am able to play the audio file ,but it is not showing any popup layout.

Media player
MediaPlayer mp = new MediaPlayer();
// Set data source -
setDataSource("/sdcard/path_to_song");
// Play audio
mp.start();
// Pause audio
mp.pause();
// Reset mediaplayer
mp.reset();
// Get song length duration - in milliseconds
mp.getDuration();
// Get current duration - in milliseconds
mp.getCurrentDuration();
// Move song to particular second - used for Forward or Backward
mp.seekTo(positon); // position in milliseconds
// Check if song is playing or not
mp.isPlaying(); // returns true or false
Hope this will give you some solution. Refer this link. It will solve your problem

#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
mMediaPlayer = new MediaPlayer();
mMediaController = new MediaController(this);
mMediaController.setMediaPlayer(PlayAudioActivity.this);
mMediaController.setAnchorView(findViewById(R.id.audioView));
String audioFile = "" ;
try {
mMediaPlayer.setDataSource(audioFile);
mMediaPlayer.prepare();
} catch (IOException e) {
System.out.println("Error in playing audio");
}
mMediaPlayer.setOnPreparedListener(new OnPreparedListener() {
#Override
public void onPrepared(MediaPlayer mp) {
mHandler.post(new Runnable() {
public void run() {
mMediaController.show(10000);
mMediaPlayer.start();
}
});
}
});
}
if you have done this then.
