sendUserActionEvent is null

Question

I ve got a real doozy here   When I click on spinners  open menu items  or open context menus on long-clicks I get the same Logcat message   08-02 21 20 57 264  E ViewRootImpl 31835   sendUserActionEvent   mView    null   The tag is ViewRootImpl  and the message is sendUserActionEvent   mView    null   I could not find anything helpful about this on the web   I searched through the Android sources and found some references to mView  but I could not find the file in which this log message is printed   For reference  I m using a Samsung Galaxy S4 running 4 2 2  or API 17   The same message does NOT occur when debugging on a Nexus 7 running Android 4 3   Any ideas   Is this a Samsung-specific issue

It is an error on all Samsung devices  the solution is  put this line in your activity declaration in Manifest  android configChanges  quot orientation screenSize quot   also when you start the activity you should do this  Intent intent   new Intent CurrentActivity this  NextActivity class   intent setType Settings ACTION SYNC SETTINGS   CurrentActivity this startActivity intent   finish     I used this to make an activity as fullscreen mode  but this question does not need the fullscreen code  but in all cases might someone need it you can refer to this question for the rest of the code  How to make VideoView full screen

This has to do with having two buttons with the same ID in two different Activities  sometimes Android Studio can t find  You just have to give your button a new ID and re Build the Project
