Android - Kill the app from the app itself-CodePudding

I have a teclast M40 pro tablet running Android Version (V11) with the app luncher to only boot one app. Now there is a problem, that sometimes the Wifi does not reconnect and a app restart is necessary. To prevent a manual restart, I would like to kill the app from the app itself and let it boot again with the app luncher.

So, how can I kill the app (Software Restart) from the app itself?

CodePudding user response：

You can use System.exit(0) to kill it and PendingIntent to start your application. Considering SplashActivity is your starting point.

Intent intent = new Intent(context, MainActivity.class);
int intentId = 123;
PendingIntent pendingIntent = PendingIntent.getActivity(context, intentId,    intent, PendingIntent.FLAG_CANCEL_CURRENT);
AlarmManager mgr = (AlarmManager)context.getSystemService(Context.ALARM_SERVICE);
mgr.set(AlarmManager.RTC, System.currentTimeMillis()   100, mPendingIntent);
System.exit(0);

you can use:

fun triggerRestart(context: Activity) {
  val intent = Intent(context, MainActivity::class.java)
  intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK)
  context.startActivity(intent)
  if (context is Activity) {
     (context as Activity).finish()
  }
  Runtime.getRuntime().exit(0)
}

and for kotlin, replace

Runtime.getRuntime().exit(0)

with

kotlin.system.exitProcess(0)
