NoClassDefFoundError - Android 2.3.X

Question

I have a Task defined in a class. Fatal exception \"NoClassDefFoundError\" is happening on following line

MyCuteTask myTask = new MyCuteTask(equations)
         


        

Answer 1

Its an google play services issue. (https://code.google.com/p/android/issues/detail?id=81083)

Workaround to avoid this crash till Google fixes it:

Add following into your Application#onCreate() method

try {
  Class.forName("android.os.AsyncTask");
}
catch(Throwable ignore) {
  // ignored
}

Note its Application#onCreate() and not Activity#onCreate()

Update: I can verify that above changes fixed these crashes for me.
