使用意图: Intent open_app = getPackageManager().getLaunchIntentForPackage("PACKAGE_NAME_ANOTHER_APP"); // like facebook package(com.facebook.katana) if (open_app != null) { startActivity(open_app); // Please check package name is there or not because it can throw NullPointerException }如果您想通过单击按钮向用户推荐 Playstore 中的任何应用程序,请执行以下操作:Uri uri = Uri.parse("https://play.google.com/store/apps/details?id=PACKAGE_NAME_OF_APP"); like facebook (com.facebook.katana)Intent intent = new Intent(Intent.ACTION_VIEW, uri);startActivity(intent);
