Answer 1

I came up this issue today, I am using Gradle.

I found out there was a folder ./build/manifests/debug/AndroidManifest.xml was generated from gradle build, and it had duplicate intent-filter of category launcher.

<intent-filter>
    <action android:name="android.intent.action.MAIN" />
    <category android:name="android.intent.category.LAUNCHER" />
</intent-filter>

...

<intent-filter>
    <action android:name="android.intent.action.MAIN" />
    <category android:name="android.intent.category.LAUNCHER" />
</intent-filter>

One of it was came by gradle dependencies compile project. So I went back and check dependencies project and remove it, and the problem solved.

Answer 3

Android's Launcher app creates an icon for each Activity in your Application that includes the intent filter android.intent.category.LAUNCHER.

Remove this intent filter from all Activities that should not be launched. In other words, define this intent filter in your main Activity, and in your main Activity only.

Answer 4

force stop your launcher from settings - app manager and clear cash data of launcher and check your problem is resolved
