someone advice me to : tip: in ur receiver class file open dialog activity - don't know how open dialog if app running in background.

any great. again

you can start activity broadcastreceiver using code:

puboic void onreceive(context context, intent intent){     ...     if (run if corrected sms received ){         // context can context object in argument of onreceive method         intent = new intent(context, playvideoactivity.class);         i.setflags(intent.flag_activity_new_task);         // use i.puextra() pass data         context.startactivity(i);     } }

after starting activity can open dialog activity or needs user interface.

and logcat showing null pointer exception. should add code playvideoactivity.dialogtextcomfirmrun() method find out wrong current approach.
