如何从另一个应用程序调用活动并在另一个应用程序堆栈中启动该活动？

Question

I have tow apps :

1. madeed app.
2. madeed manager :with launcher activity called MainActivity and this Activity has intent filter with this schema: android:scheme=madeed-manager .

madeed app has a button which direct the user to madeed manager . by running this code :

String url = "madeed-manager://";
            Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse(url));
            context.startActivity(intent);

the code works fine and madeed manager MainActivity launches. but the problem that madeed manager activity is added to madeed stack . so if the user tab on madeed app icon . madeed manager will appear. How to let the activity to be launched in another stack. thanks

EDIT : when i add FLAG_ACTIVITY_NEW_TASK flag, then it works normally. but i don't know the reason.

Follow 2 Steps:

1: Add an <intent-filter> to the third activity with a action:

<intent-filter>
  <action android:name="com.package.xxxx.yyyyy.SOMETHING"/>
  <category android:name="android.intent.category.DEFAULT" />
</intent-filter>

2: Start Intent

startActivity(new Intent("com.package.xxxx.yyyyy.SOMETHING"));
