从上次打开的活动中启动另一个应用程序意图（恢复）

Question

I use the following code to launch other apps:

Intent intent = new Intent();
intent.addCategory(CATEGORY_LAUNCHER);
intent.setComponent(new ComponentName(packageName, activity));
intent.setFlags(FLAG_ACTIVITY_NEW_TASK);
startActivity(intent);

This works however it makes the launched app start from the beginning, not from the last opened activity (resuming it). Is there something wrong with my code?

Answer 1

Use a "launch Intent ", like this:

Intent intent = getPackageManager().getLaunchIntentForPackage(packageName);
startActivity(intent);

This Intent has all the necessary flags and settings to bring an existig task to the foreground or to start a new one (if the app is not running).
