In my application i am using ToneGenerator to play simple sound. When test my application by compiling the application with 6.0, my application randomy crashing due to ToneGenerator init method. Below is the exception.
java.lang.RuntimeException: Init failed
04-21 12:34:05.497 7166 7166 E MyApplication: at android.media.ToneGenerator.native_setup(Native Method)
04-21 12:34:05.497 7166 7166 E MyApplication: at android.media.ToneGenerator.<init>(ToneGenerator.java:746)
I am using the tone generator in below way.
public ToneGenerator toneGenerator;
public void playSound() {
if (toneGenerator == null) {
toneGenerator = new ToneGenerator(AudioManager.STREAM_NOTIFICATION, 100);
}
toneGenerator.startTone(ToneGenerator.TONE_CDMA_ANSWER, 200);
}
public void releaseToneGenerator() {
if (toneGenerator != null) {
toneGenerator.release();
}
}
Any one faced same issue?..Previously my application was running on 4.4 and in that we did not observe any crash. In in 6.0 application is crashing
Solved the issue by using handler.
private static void playTone(Context context, int mediaFileRawId) {
Log.d(TAG, "playTone");
try {
if (toneGenerator == null) {
toneGenerator = new ToneGenerator(AudioManager.STREAM_NOTIFICATION, 100);
}
toneGenerator.startTone(mediaFileRawId, 200);
Handler handler = new Handler(Looper.getMainLooper());
handler.postDelayed(new Runnable() {
@Override
public void run() {
if (toneGenerator != null) {
Log.d(TAG, "ToneGenerator released");
toneGenerator.release();
toneGenerator = null;
}
}
}, 200);
} catch (Exception e) {
Log.d(TAG, "Exception while playing sound:" + e);
}
}
Following is a Tone Generator based solution that appears stable, using an ontouch listener in a DialogFragment. Set your onTouchListeners for each button in the OnViewCreated method, then use the following ontouch listener method, that continuously plays the selected DTMF tone over the SIP call while touching a button, then stops playing when the button is no longer touched. The AnswerDialogListener is the callback to the MainActivity.
Edit: I broke the previously working DTMF tone RFC2833 proper output by trying to fix a compiler warning by using toneType = ToneGenerator.TONE_DTMF_0; instead of toneType = toneGenerator.TONE_DTMF_0;
private View.OnTouchListener myTouchListener = new View.OnTouchListener(){
public boolean onTouch(View v, MotionEvent event) {
String callidText = callid;
AnswerDialogListener listener = (AnswerDialogListener) getActivity();
int streamType = AudioManager.STREAM_MUSIC;
int volume = 50;
if(event.getAction() == MotionEvent.ACTION_DOWN) {
switch (v.getId()) {
case R.id.answer_dialog_0_button:
toneGenerator = new ToneGenerator(streamType, volume);
toneGenerator.getAudioSessionId();
listener.onAnswerResponse(callidText, "Keypad0");
toneType = toneGenerator.TONE_DTMF_0;
toneGenerator.startTone(toneType);
return true;

Following is a snippet of the if statement in the MainActivity callback handler to output the DTMF on the active SIP call:
if (response.equals("Keypad0")) {
try {
if (call != null) {
call.sendDtmf(0);
}
} catch (Exception e) {
e.printStackTrace();
}
} else if (response.equals("Keypad1")) {
try {
if (call != null) {
call.sendDtmf(1);
}
} catch (Exception e) {
e.printStackTrace();
}
}
