Two apps after react-native run-android

Question

I'm making a react native app and earlier it was working fine but now when I run "react-native run-android", after the successful install and launch, I can see two apps in the simulator and both of them are working fine.
So, any ideas why I'm seeing 2 apps or should I say why I'm getting an extra duplicate app installed?

Answer 1

I think you added splash screen in your app after it you have this problem, first go to this Dir: android/app/src/main/AndroidManifest.xml if you add two time something like this

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

it will render two times and build two apps on your device.

in my file

AndroidManifest.xml

<!-- remove just first part the activity, but i comment this part -->

  <!-- <activity
    android:name=".SplashActivity"
    android:theme="@style/SplashTheme"
    android:label="@string/app_name">
    <intent-filter>
        <action android:name="android.intent.action.MAIN" />
        <category android:name="android.intent.category.LAUNCHER" />
    </intent-filter>
  </activity> -->



  <activity
    android:name=".MainActivity"
    android:label="@string/app_name"
    android:theme="@style/SplashTheme"
    android:configChanges="keyboard|keyboardHidden|orientation|screenSize"
    android:windowSoftInputMode="adjustResize">
    <intent-filter>
        <action android:name="android.intent.action.MAIN" />
        <category android:name="android.intent.category.LAUNCHER" />
    </intent-filter>
  </activity>

Answer 2

The problem is due to multiple category LAUNCHER in both splash and main activity.

<category android:name="android.intent.category.LAUNCHER" />

The solution with both SplashActivity and MainActivity is to change

<category android:name="android.intent.category.LAUNCHER" />

to

<category android:name="android.intent.category.DEFAULT" />

in MainActivity.

The file with both .SplashActivity and .MainActivity looks like this;

    <activity
        android:name=".SplashActivity"
        android:theme="@style/SplashTheme"
        android:label="@string/app_name">
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />
            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
    <activity
        android:name=".MainActivity"
        android:label="@string/app_name"
        android:configChanges="keyboard|keyboardHidden|orientation|screenSize"
        android:windowSoftInputMode="adjustResize"
        android:exported="true">
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />
            <category android:name="android.intent.category.DEFAULT" />
            <category android:name="android.intent.category.BROWSABLE" />
        </intent-filter>
    </activity>
