Thread in my code does not work - android

Here is the code, Results Activity should start if button is clicked:
public class Tab19 extends Activity {
ImageButton button1;
SoundPool mSoundPool;
AssetManager assets;
int catSound;
int countLoadedSound;
Context mContext;
ProgressDialog dialog;
int count = 0;
TextView t;
boolean has_been_clicked = false;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_tab19);
count = getIntent().getIntExtra("CountNum", 0);
mContext = this;
mSoundPool = new SoundPool(2, AudioManager.STREAM_MUSIC, 0);
assets = getAssets();
catSound = loadSound("catSound.mp3");
button1 = (ImageButton)findViewById(R.id.button2);
button1.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
playSound(catSound);
Intent firstIntent = new Intent(Tab19.this, Results.class);
TextView t = (TextView)findViewById(R.id.t);
t.setText("score: " + ++count +"/18");
firstIntent.putExtra("CountNum", count);
has_been_clicked = true;
startActivity(firstIntent);
finish();
}
});
new Thread(
new Runnable() {
public void run() {
while (!has_been_clicked) {
try {
// Thread will sleep for 10 seconds
sleep(10*1000);
} catch (Exception e) {
}
}
Intent i=new Intent(getBaseContext(),Results.class);
i.putExtra("CountNum", count);
startActivity(i);
finish();
return;
}
private void sleep(int i) {
// TODO Auto-generated method stub
}
}
).start(); }
#Override
protected void onDestroy() {
super.onDestroy(); }
protected void playSound(int sound) {
if (sound > 0)
mSoundPool.play(sound, 1, 1, 1, 0, 1);
}
private int loadSound(String fileName) {
AssetFileDescriptor afd = null;
try {
afd = assets.openFd(fileName);
} catch (IOException e) {
e.printStackTrace();
Toast.makeText(this, "Не могу загрузить файл " + fileName,
Toast.LENGTH_SHORT).show();
return -1;
}
return mSoundPool.load(afd, 1);
} }
If button is not clicked Thread should start next Activity within 10 seconds, but it does not happen, please help me find a mistake. Thanks in advance


Into your thread change the while loop into an if statement:
if (!has_been_clicked) {
try {
// Thread will sleep for 10 seconds
sleep(10*1000);
} catch (Exception e) {
}
}


I think you should change your code to
boolean has_been_clicked = true;
...
while (has_been_clicked) {
has_been_clicked = false;
try {
// Thread will sleep for 10 seconds
sleep(10*1000);
} catch (Exception e) {
}
}
Intent i=new Intent(getBaseContext(),Results.class);
i.putExtra("CountNum", count);
startActivity(i);
finish();
return;

please help me in fixing this issues..
Thank you in advance..

In your onStop() of your activity stop and release the media player.
Place the below code in your onStop():
#Override
public void onStop() {
super.onStop();
if(media != null){
media.stop(); //Stops playback after playback has been stopped or paused
media.release(); //Releases resources associated with this MediaPlayer object
media = null;
}
if(mediaPlayer!= null){
mediaPlayer.stop();
mediaPlayer.release();
mediaPlayer= null;
}
}
This is the proper way to stop media player.
Hope it helps:)

Video stops and goes to initial stage after exiting full screen to normal screen

I am working on a video player where I have used custom play/pause, fullscreen etc control buttons for normal screen and default media controller for full screen, which I have customized by adding a control button so that the full screen can be exited and switch back to normal small screen. I am able to full screen the video, but once I click that control button in full screen mode, the video stops and goes back to initial state, though the full screen can be switched to normal screen mode. What I should I do or change in my code so that the video can continue playing? I am searching google for the past three hours still could not find an exact solution. :(
Here is my code:

AudioRecorder App crashes when I record a second time

My app breaks down when I attempt to record a second a time when I hit the stop button. I went through this code several times. I can't find the problem. I'm not sure if its my MediaRecorder or my MediaPlayer. It works the first time around. But not the second time. can anyone find the problem.

Here is my logCat:

I figured out the issue. In the beginRecording method, I have an if and else statement that handles the output file. Unfortunately, the code that I had in the else statement was something that I wanted to always run no matter what.

I have 2 activities. I need to play one background music to all the activities.I want play and stop song from main activity

This is my main activity which is actually a tab activity. I am choosing list of song and i am trying to play radio in activity given below.

you need a Service which is independent to the activity to play the song
public class SongService extends Service {
MediaPlayer mm;
#Override
public IBinder onBind(Intent intent) {
// TODO Auto-generated method stub
return null;
}
#Override
public void onCreate() {
// TODO Auto-generated method stub
super.onCreate();
mm = MediaPlayer.create(this, R.raw.mainmenu2);
mm.setLooping(true);
}
#Override
public void onDestroy() {
// TODO Auto-generated method stub
super.onDestroy();
mm.stop();
}
#Override
public void onStart(Intent intent, int startId) {
// TODO Auto-generated method stub
super.onStart(intent, startId);
mm.start();
}
}
then add this whenever you want to play the song in the service.
startService(new Intent(this, SongService.class));
and to finish it add this:
stopService(new Intent(MainMenu.this,SongService.class));
So when you press the button start the service, and whenever you press the stop button stop it. this is how you can play songs through activities.

First you have to create a raw folder in res folder and paste the song you want to play there.
MainActivity,java======
protected void onCreate(){
MediaPlayer backgroundSong;
backgroundSong = MediaPlayer.create(MainActivity.this, R.raw.your_song_name);
backgroundSong.start();}
#Override
protected void stopSong() {
// TODO Auto-generated method stub
backgroundSong.release();
}
OtherActivity.java
protected void onPause(){
MainActivity ma = new MainActivity();
ma.stopSong();
}

I Want to detect Screen Resolution

I have an android application with a country map divided into Districts...
and in the database.xml file i put the XY coordinates positions for each District in the map...
But, when I run the application on a device with a different screen size,
the positions change and Didn't fit the positions that I need!
So, Please I Want to know how to detect the screen size, and create a separate XY database for each screen resolution!
Thank you in Advance,
here is the MainActivity.java Code, if you want anything else I will post it,
please I need your help! :(

You can use something like:
Display myDisplay = getWindowManager().getDefaultDisplay();
Point point = new Point();
myDisplay.getSize(point);
int width = point.x;
int height = point.y;
as per this awesome answer.
If your map view is not full screen then I suggest using percentages to set the size of the map. This way you can use a percentage offset with your coordinates to alleviate the varying screen size issue. You definitely don't want to store different sets of XML co-ordinates for different screen resolutions.
