I m going to say that it is not possible to completely prevent screen video capture of any android app through supported means  But if you only want to block it for normal android devices  the SECURE FLAG is substantial   1  The secure flag does block both normal screenshot and video capture      Also documentation at this link says that           Window flag  treat the content of the window as secure  preventing it from appearing in screenshots or from being viewed on non-secure displays          Above solution will surely prevent applications from capturing Video of your app   See the answer here   2  There are alternative means of capturing screen content   It may be possible to capture the screen of another app on a rooted device or through using the SDK      which both offer little to no chance of you either blocking it or receiving notification of it    For example  there exists software to mirror your phone screen to your computer via the SDK and so screen capture software could be used there  undiscoverable by your app   See the answer here   getWindow   setFlags LayoutParams FLAG SECURE  LayoutParams FLAG SECURE

You can make your app as device profile owner and call setScreenCaptureDisabled    From the  docs  this api does the following      public void setScreenCaptureDisabled  ComponentName admin  boolean disabled    Added in API level 21      Called by a device profile owner to set whether the screen capture is   disabled  Disabling screen capture also prevents the content from   being shown on display devices that do not have a secure video output    See FLAG SECURE for more details about secure surfaces and secure   displays       The calling device admin must be a device or profile owner  If it is   not  a security exception will be thrown  Parameters admin    Which   DeviceAdminReceiver this request is associated with  disabled     Whether   screen capture is disabled or not    Alternatively you can become an MDM Mobile Device Management  partner app OEMs provides additional APIs to their MDM partner apps to control the device For example samsung provides  api to control screen recording on the device to their MDM partners   Currently this is the only way you can enforce screen capture restrictions

I saw all of the answers which are appropriate only for a single activity but there is my solution which will block screenshot for all of the activities without adding any code to the activity  First of all make an Custom Application class and add a registerActivityLifecycleCallbacks Then register it in your manifest   MyApplicationContext class  public class MyApplicationContext extends Application       private  Context context      public void onCreate             super onCreate            context   getApplicationContext            setupActivityListener               private void setupActivityListener             registerActivityLifecycleCallbacks new ActivityLifecycleCallbacks                  Override             public void onActivityCreated Activity activity  Bundle savedInstanceState                    activity getWindow   setFlags WindowManager LayoutParams FLAG SECURE  WindowManager LayoutParams FLAG SECURE                             Override             public void onActivityStarted Activity activity                               Override             public void onActivityResumed Activity activity                                Override             public void onActivityPaused Activity activity                                Override             public void onActivityStopped Activity activity                               Override             public void onActivitySaveInstanceState Activity activity  Bundle outState                               Override             public void onActivityDestroyed Activity activity                                             Manifest     lt application         android name   MyApplicationContext          android allowBackup  true          android icon   mipmap ic launcher          android label   string app name          android roundIcon   mipmap ic launcher round          android supportsRtl  true          android theme   style AppTheme  gt
