        {
            //mCheckLicenseButton.setEnabled(false);
            setProgressBarIndeterminateVisibility(true);
            //mStatusText.setText(R.string.checking_license);
            mChecker.checkAccess(mLicenseCheckerCallback);
        }
     @Override // for the License
        protected void onDestroy() {
            super.onDestroy();
            mChecker.onDestroy();
        }
}

I think there might be the problem in thread. . . Please help me to solve it. . Thanks Please help me in this. . . And let me tell while i am able to run the application only at once. . . Thanks in advance.

Can you try splashHandler.postDelayed(new Runnable(), DURATION); ?

and put it up to fields private Handler splashHandler = new Handler();
