android - event when input is active to accept text -


I am trying to run a service in the background which is when there is an input field Then some will appear (within any app, such as SMS, Facebook etc.), but how could I have done that 

  mImm = (InputMethodManager) mContext.getSystemService (context.INPUT_METHOD_SERVICE ); If (mImm.isAcceptingText ()) {Toast. Make Text (mContext, "Show Something", Toast. LNNGHHORT) Show (); }   
 Trick moves in my background service, but it   
 
 
 You can use one, though in that case teeth should work, in which case a notification is more suitable and professional (IMO).  
 Toast is not showing because the reference user you use is not from the user interface thread.
