Use flag in two Activity connect (Android)

Question

I'm building an android application, with two activities: MainActivity and PlayMovieActivity . In the MainActivity , I have one button to start play movie Activity , like :

Intent intent = new Intent();
intent setClassName("xxx.xxx","xxx.startmovie");
startActivity(intent);

Unfortunately , that connect not always smooth , sometime , it will not connect. I try to use a flag to judgment connect or not connect. Is there any way to do it ?

in fact , intent to another Activity is OK , but sometimes it's not ok . I don't know . if playmovie Activity not working , the button is visible can let you press again, but if it's working , the button is invisible.

Answer 1

An Intent is an object that provides runtime binding between separate components, such as two activities. The Intent represents an app's "intent to do something."

Remove setClassName

Intent intent = new Intent(this,PlayMovieActivity.class);
startActivity(intent);

Answer 2

Try this,

Intent intent = new Intent(this, PlayMovieActivity.class);
startActivity(intent);
