I can't find android.os.IVibratorService.Stub class like in tutorial so i use this part of code to implement vibration feature:



There no exception and errors, but LogCat don't show any vibration action

I suspect that the changes made too the OS in the last year since this was originally posted mean the originally stated method no longer works. As for Bosslys method, It has no problems when written but produces a force close when run on the phone.

Anyone able to shed light on this?

You need to include the VIBRATE uses permissions to the manifest.

hey guys, I'm trying to write some code that makes the phone vibrate and for testing purpose, I have made it so that when I press the volume up/down buttons it should vibrate, but the application is forced close, when I press a button.

My code is as following:

package example.Volume;

import android.app.Activity;
import android.os.Bundle;
import android.os.Vibrator;
import android.view.KeyEvent;
import android.content.Context;
import android.content.Intent;

public class Volume extends Activity {

private Vibrator vibrator;
int milliseconds = 500;
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);

}

@Override
//Creates a function that listen for whether a key is pressed
public boolean onKeyDown(int keyCode, KeyEvent ev) {//int _keyCode, KeyEvent _event)
switch(keyCode){
//Creates a case for each of the keys to listen to
case KeyEvent.KEYCODE_VOLUME_DOWN:
//Tells the application what to do when VOLUME_DOWN is pressed
vibrator.vibrate(milliseconds);
break;
case KeyEvent.KEYCODE_VOLUME_UP:
vibrator.vibrate(milliseconds);
break;
default:
return false;
}
return true;
}


}

hi,

can any on can confirm that logcat output does not exist anymore with SDK 1.6? i use "vibrate" with getSystemService and nothing in log but no exception too ... i can see what i'm writing in log but nothing more ...

}

Maybe you can check manifest permission for vibrate function

Hi there,

I have the same problem as described above: When my emulator vibrates nothing is shown in the log file.
Does anybody know if this is normal in newer (above 1.6) API versions?

Thanks a lot!
