Put Phone In Vibrate In Android Code

I am trying to activate vibrate in android but evrey time i press the button the app crash..... silet.setRingerMode(AudioManager.RINGER_MODE_VIBRATE) also i did the import thing.

Solution 1:

I'm taking a guess, but you declared:

public AudioManager silent;

Have you initialized it with:

AudioManagersilent= (AudioManager) getSystemService(AUDIO_SERVICE);

And you spelled silent wrong here:

silent.setRingerMode(AudioManager.RINGER_MODE_VIBRATE);
//silet.setRingerMode(AudioManager.RINGER_MODE_VIBRATE);

Solution 2:

Try this code it will help you

       AudioManager audio = (AudioManager) getSystemService(Context.AUDIO_SERVICE);
       audio.setRingerMode(AudioManager.RINGER_MODE_VIBRATE);

Need to add permission in AndroidManifest.xml

<uses-permissionandroid:name="android.permission.VIBRATE"/>

Enjoy!!!
