Start an app from a running background service

Question

Just wondering if its possible to launch an install application from a background service. I have the packagename as well.

Answer 1

An installed application can be invoked using PackageManager class

startActivity(BackgroundService.this.getPackageManager()
                .getLaunchIntentForPackage(packageName)
                .setFlags(Intent.FLAG_ACTIVITY_NEW_TASK));

Answer 2

是的，您可以从服务启动活动。

Answer 3

Intent intent= getPackageManager().getLaunchIntentForPackage("com.example.package_name");
startActivity( intent);

For more information you can see package manager and getLaunchIntentForPackage

Answer 4

yes you can launch an activity from a service. use this code this is worked for me

Intent mIntent = new Intent(getApplicationContext(), YourActivity.class);
mIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
getApplicationContext().startActivity(mIntent);

don't forget to called mIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK) otherwise its gives error
