Original: Android Project Combat (22): Launch another app or restart the app

First, launch another app

Current company project needs, a main app, need to open some small apps, these small apps are integrated unity, but still Android program (all small app package name is known).

Did not do before, query the implementation method, in fact, is quite simple, testing can also.

The code is relatively simple, directly affixed to:

Try {            = getactivity (). Getpackagemanager ();            Intent Intent=new  Intent ();             = Packagemanager.getlaunchintentforpackage ("com.maiji.textviewchangedemo"); Here the parameter is the package name of the app you want to open            startactivity (        intent); Catch (Exception e) {            log.e (" Error opening another application ", E.getmessage ());   is not open, the app you might want to open is not installed and needs to be processed again        }

2. Restart the app

This feature is relatively rare, in the QQ set font size will restart the app

Code:

                Intent Intent = getbasecontext (). Getpackagemanager ()                        . Getlaunchintentforpackage (Getbasecontext (). Getpackagename ());                Intent.addflags (intent.flag_activity_clear_top);                StartActivity (intent);
