Android Intents: Start activity using class name from another app that has the same sharedUserId

问题

All my apps have the same sharedUserId. I would like to start a class of another app using the class of my current app. I want to use intent extras but I do not want to use intent URLs. I also would prefer not to have to change the AndroidManifest of my target activity's app.

回答1:

Its pretty easy since you have the sharedUserId set.

Intent res = new Intent();
String mPackage = "com.your.package";
String mClass = ".actYouAreLaunching";
res.setComponent(new ComponentName(mPackage,mPackage+mClass));
startActivity(res);

And that's all there is to it. You can add intent extras like you normally would.
