Disabling screen shot capture in Android application

Reference:

只要在呼叫setContentView()之前設定FLAG_SECURE的windows flag，這個頁面就無法被截圖或錄影

按  hardware key截圖時，會出現下列的log

01-01 21:11:50.538 10930-10930/? D/ScreenshotUtils: notifyScreenShotError, first screenshot

Code snippet:

 @Override

protected void onCreate(Bundle savedInstanceState) {

    super.onCreate(savedInstanceState);

    getWindow().setFlags(WindowManager.LayoutParams.FLAG_SECURE,

            WindowManager.LayoutParams.FLAG_SECURE);

    setContentView(R.layout.activity_main);

    ...

}
