Help with first Android Activity

Question

When my app first opens my first activity that is presented to the user can vary based on configuration options. I only know how to hard code the first activity that runs when the app is running by adding something like this in the Manifest

<activity android:label="@string/app_name" android:name=".MyFirstActivity">
    <intent-filter>
        <action android:name="android.intent.action.MAIN" />
        <category android:name="android.intent.category.LAUNCHER" />
    </intent-filter>
</activity>

Where MyFirstActivity is the class name of the first activity class to be run. How can I dynamically select which activity to run first when the app is first launched rather than hard code it in the manifest?

Thanks!

Answer 1

Option #1: In onCreate() of MyFirstActivity, call startActivity() for the right activity, then finish().

Option #2: Define several activities with the LAUNCHER <intent-filter>, all but one disabled. On first run (or as needed), enable the right activity and disable the others. Downside: may require a phone reboot to update the launcher, since not all home screen launchers will detect your change.

Option #3: Redesign your GUI such that this is not an issue.
