error when startanimation()

Beautiful animation. I have a problem when init call mBtLogin.startAnimation(), animation not load full in onCreate. I fix it as put startAnimation in a Handler().postdelay. How to direct call startAnimation() when start app. Thanks.

 @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
       CircularProgressButton mBtLogin = (CircularProgressButton) findViewById(R.id.progress_btn_change_activity);
        mBtLogin.startAnimation();
        /*new Handler().postDelayed(new Runnable() {
            @Override
            public void run() {
                mBtLogin.startAnimation();
            }
        }, 100);*/
}

@leandroBorgesFerreira, sorry to disagree, but this doesn’t require much of a fix. onCreate() is not supposed to be used for animating things nor explicit app logic (such as Login) as this can lead to several issues such as lagging due to early fired GC’s and others. @frankenten13, you should read about the activity lifecycle and when are you supposed to invoke certain parts of your code. Invoking a Login function during onCreate() is a pretty terrible design decision; you are delaying your activity creation process.

As per Android documentation:

In the onCreate() method, you perform basic application startup logic that should happen only once for the entire life of the activity.

This problem was already fixed. The button accepts animation commands before the screen get drawn and waits for the right time for the animation to start.
