Title Body

I got some error messages from my application on a simple button click. After the click an animation should start, but the button becomes bigger. It runs perfectly on most devices, but on some (i think mostly 4.X and above) it crashes. Exception message (Stack Trace): java.lang.NullPointerException at android.view.GLES20RecordingCanvas.drawBitmap(GLES20RecordingCanvas.java:118) at android.graphics.drawable.BitmapDrawable.draw(BitmapDrawable.java:400) at android.view.View.draw(View.java:10999) at android.view.ViewGroup.drawChild(ViewGroup.java:3186) at android.view.ViewGroup.dispatchDraw(ViewGroup.java:2788) at android.view.ViewGroup.drawChild(ViewGroup.java:3184) at android.view.ViewGroup.dispatchDraw(ViewGroup.java:2788) at android.view.ViewGroup.drawChild(ViewGroup.java:3184) at android.view.ViewGroup.dispatchDraw(ViewGroup.java:2788) at android.view.ViewGroup.drawChild(ViewGroup.java:3184) at android.view.ViewGroup.dispatchDraw(ViewGroup.java:2788) at android.view.View.draw(View.java:11017) at android.view.View.getDisplayList(View.java:10444) at android.view.ViewGroup.dispatchGetDisplayList(ViewGroup.java:2896) at android.view.View.getDisplayList(View.java:10407) at android.view.ViewGroup.dispatchGetDisplayList(ViewGroup.java:2896) at android.view.View.getDisplayList(View.java:10407) at android.view.ViewGroup.dispatchGetDisplayList(ViewGroup.java:2896) at android.view.View.getDisplayList(View.java:10407) at android.view.HardwareRenderer$GlRenderer.draw(HardwareRenderer.java:883) at android.view.ViewRootImpl.draw(ViewRootImpl.java:2089) at android.view.ViewRootImpl.performTraversals(ViewRootImpl.java:1781) at android.view.ViewRootImpl.handleMessage(ViewRootImpl.java:2666) at android.os.Handler.dispatchMessage(Handler.java:99) at android.os.Looper.loop(Looper.java:156) at android.app.ActivityThread.main(ActivityThread.java:4977) at java.lang.reflect.Method.invokeNative(Native Method) at java.lang.reflect.Method.invoke(Method.java:511) at
