I am trying to download an mp3 file. For this i have created an activity like this:
public class audiostream extends Activity{
private Button streamButton;
private ImageButton playButton;
private TextView textStreamed;
private boolean isPlaying;
private StreamingMediaPlayer audioStreamer; //This is the object of supporting class
protected void onCreate(Bundle savedInstanceState){
super.onCreate(savedInstanceState);
//other activities }
now on the button click event i am calling this function:
private void startStreamingAudio() {
try {
final ProgressBar progressBar = (ProgressBar) findViewById(R.id.progress_bar);
if ( audioStreamer != null) {
audioStreamer.interrupt();
}
audioStreamer = new StreamingMediaPlayer(this,textStreamed, playButton, streamButton,progressBar);
audioStreamer.startStreaming("file path",file_size,duration);
streamButton.setEnabled(false);
} catch (IOException e) {
}
}
Give below is the StreamingMediaPlayer class:
public class StreamingMediaPlayer {
private TextView textStreamed;
private ImageButton playButton;
private ProgressBar progressBar;
public StreamingMediaPlayer(Context context,TextView textStreamed, ImageButton playButton, Button streamButton,ProgressBar progressBar)
{
this.context = context;
this.textStreamed = textStreamed;
this.playButton = playButton;
this.progressBar = progressBar;
}
}
Rest of the works are done by the remaining class such as incrementing the progress bar, playing the audio etc.
Progress bar increments as audio progresses. The issue that i am facing is that, while playing the audio, if i am pressing back button and opening previous activity the audio plays (this is what i want), but when i come back to the activity with the help of intent, everything appears in a way that activity is just created. The progress bar which was previously progressing now looks when i first opened this activity. In simple sentence the problem is that, the activity which is playing the audio file is not resuming the previous state. Kindly help me.
