I am encountering this error whenever i do a mp.stop in android, basically an sms with body RING:(password) to play the audio and STOP:(password) to stop the audio. The play is working fine but not the stop.
MediaPlayer mp = MediaPlayer.create(context, R.raw.braincandy);
if (correctSHA1 != null) {
if (intent.getAction().equals(SMS_RECEIVED)) {
Bundle bundle = intent.getExtras();
if (bundle != null) {
Object pdus[] = (Object[]) bundle.get("pdus");
SmsMessage smsMessage[] = new SmsMessage[pdus.length];
for(int i = 0; i < pdus.length; i++) {
smsMessage[i] = SmsMessage.createFromPdu((byte[])pdus[i]);
if (smsMessage[i].getMessageBody().contains("RING:")) {
String[] tokens = smsMessage[i].getMessageBody().split(":");
Log.v(TAG, "RING SMS Message keyword detected");
if (tokens.length >= 2) {
Log.v(TAG, "Token 1: " + tokens[0]);
Log.v(TAG, "Token 2: " + tokens[1]);
String SHA1hash = PhoneFinder.getSHA1(tokens[1]);
Log.v(TAG, "SHA1 Hash:" + SHA1hash);
Log.v(TAG, "Correct SHA1:" + correctSHA1);
if (SHA1hash.equals(correctSHA1)) {
Log.v(TAG, "SHA1 hash matched!");
this.abortBroadcast(); //Abort Broadcast for SMS Message
String to = smsMessage[i].getOriginatingAddress ();
SmsManager sm = SmsManager.getDefault();
sm.sendTextMessage (to, null, "success!", null, null);
NotificationManager nm = (NotificationManager) context.getSystemService (Context.NOTIFICATION_SERVICE);
Notification notification = new Notification(android.R.drawable.ic_dialog_info, "Alert", System.currentTimeMillis());
PendingIntent contentIntent = PendingIntent.getActivity (context, 0, new Intent (context, PhoneFinder.class), 0);
notification.setLatestEventInfo (context, "GPS address", "You have been detected", contentIntent);
nm.notify (R.string.service_start, notification);
//context.startService(new Intent(context, MyService.class));
mp.start();
}
}
}
else if (smsMessage[i].getMessageBody().contains("STOP:")) {
String[] tokens = smsMessage[i].getMessageBody().split(":");
Log.v(TAG, "STOP SMS Message keyword detected");
if (tokens.length >= 2) {
Log.v(TAG, "STOP Token 1: " + tokens[0]);
Log.v(TAG, "STOP Token 2: " + tokens[1]);
String SHA1hash = PhoneFinder.getSHA1(tokens[1]);
Log.v(TAG, "STOP SHA1 Hash:" + SHA1hash);
Log.v(TAG, "STOP Correct SHA1:" + correctSHA1);
if (SHA1hash.equals(correctSHA1)) {
Log.v(TAG, "STOP SHA1 hash matched!");
this.abortBroadcast(); //Abort Broadcast for SMS Message
// context.stopService(new Intent(context, MyService.class));
if (mp.isPlaying())
mp.pause();
}
}

You are not allowed to call pause() right after initializing a media player. You can call it only at certain states. These states are defined by a state diagram illustrated in below figure.
EDIT: You said you want it to stop, so things have changed.
