I'd like to start an Activity which is not included in my original .apk. How can I do so? the other Activity is contained in another .apk which is previous version of the current application. Thanks, Eyal.

推荐答案

如果你只知道包名，这个方法很好:

This method is good if you only know the package name:

PackageManager pm = getPackageManager();
Intent intent = pm.getLaunchIntentForPackage("com.the.other.app");
startActivity(intent);
