Extern help required for android vibration

Hey guys,

The documentation is cryptic to me and I've also looked at S3nk's QRCode monkey and native .java files to try implement the android vibration functionality in my game.
I based it off diddy's android.java file https://code.google.com/p/diddy/source/browse/src/diddy/native/diddy.android.java

My java file (game.android.java) is as follows:

import android.os.Vibrator;

class _game {
	public static Vibrator vibrator;
	public static String inputString = "";
	
	public static void startVibrate(int millisec)
	{
		try {
			vibrator = (Vibrator)BBAndroidGame._androidGame._activity.getSystemService(Context.VIBRATOR_SERVICE);
			if (vibrator!=null)
				vibrator.vibrate(millisec);
		} catch (java.lang.SecurityException e) {
			android.util.Log.e("[Monkey]", "SecurityException: " + android.util.Log.getStackTraceString(e));
		}
	}

	public static void stopVibrate()
	{
		try {
			if (vibrator!=null)
				vibrator.cancel();
		} catch (java.lang.SecurityException e) {
			android.util.Log.e("[Monkey]", "SecurityException: " + android.util.Log.getStackTraceString(e));
		}
	}
}

And my monkey source is as follows:

Strict
Import mojo
Import "native/game.${TARGET}.${LANG}"
Extern
	'Class game = "_game"
	'	Function startVibrate:game(mill:Int)
	'	Function stopVibrate:game()
	'End
	Function startVibrate:Int(mill:Int) = "_game.startVibrate"
	Function stopVibrate:Int() = "_game.stopVibrate"
Public ' Back to monkey code

As can be seen above, I've tried the extern code in two ways. In the first commented out way, I tried calling it in my monkey source like so:

If Enemy.DetectHit(x, y)
  #If TARGET = "android"
    game.startVibrate(1000)
   #End
End

And in the latter implementation above, the same, but just using "startVibrate(1000)" without the game. preceding it.

I've tried it on my tablet and I get no vibration at all.

Anyone know what I am doing wrong?

You need to a permission to the AndroidManifest to make vibrate work:

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

(Also remember to add the MIT license when using Diddy code)

Thanks Steve! I'll give it a go tonight. Don't worry, I'll include the licence 😀

Good luck :)

Also if you want to add the AndroidManifest stuff via code, in your MonkeyX code you can do something like this:

#ANDROID_MANIFEST_APPLICATION+="<activity android:name=~qcom.google.ads.AdActivity~q android:configChanges=~qkeyboard|keyboardHidden|orientation|screenLayout|uiMode|screenSize|smallestScreenSize~q />"

So for the vibrate you could try:

#ANDROID_MANIFEST_MAIN+="<uses-permission android:name=~qandroid.permission.VIBRATE~q />"

As you need to add it to the "main" part of the manifest.

Thanks a lot Steve. That worked a treat. I added it in the source as in your last example. Now to try get the Xbox 360 desktop controller to vibrate and the Ouya :)

Well I was stupid enough to think that vibration is supported on other platforms. No vibration on Ouya, Vita or desktop. Not sure if I can get it to work for Xna builds yet but still looking into it.
If only there was a universal vibration option for all platforms :)
