protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == 1) {
if (resultCode == RESULT_OK) {
uri = data.getData();
Cursor returnCursor = getContentResolver().query(uri, null, null, null, null);
int nameIndex = returnCursor.getColumnIndex(OpenableColumns.DISPLAY_NAME);
returnCursor.moveToFirst();
path = uri.getPath();
Toast.makeText(MainActivity.this, path, Toast.LENGTH_LONG).show();
// song.setText(returnCursor.getString(nameIndex));
}
}
super.onActivityResult(requestCode, resultCode, data);
}
}
this code is choose button select the audio file and select audio song
After the passing the uri media player parse the uri attach the url but does not playing sound

public class MainActivity extends AppCompatActivity {

}
};
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == SOUND_LOAD_REQUEST)

try {

} catch (IOException e) {

}
mMediaPlayer.prepareAsync();
b3.setOnClickListener(new View.OnClickListener() {
#Override

finalTime = mMediaPlayer.getDuration();
startTime = mMediaPlayer.getCurrentPosition();
if (oneTimeOnly == 0) {
seekbar.setMax((int) finalTime);
oneTimeOnly = 1;
}
tx2.setText(String.format("%d min, %d sec",
TimeUnit.MILLISECONDS.toMinutes((long) finalTime),
TimeUnit.MILLISECONDS.toSeconds((long) finalTime) -
TimeUnit.MINUTES.toSeconds(TimeUnit.MILLISECONDS.toMinutes((long) finalTime)))
);

);
seekbar.setProgress((int) startTime);
myHandler.postDelayed(UpdateSongTime, 100);
b2.setEnabled(true);
b3.setEnabled(false);
}
});
}
}
}
This code is finally working
