Merging android manifest files, conflicting filter

Question

I'm trying to combine android manifest files from 2 plugins in Unity, but there are two activities with the same intent-filter and I can only get 1 or the other to work at the same time....

Of the 2 conflicting activities, whichever is on top in the manifest file is the one that will work. So if activity from manifest #1 is on top, plugin #1 will work but not #2, and vice versa.

The two conflicting activities are:

<activity
        android:name="com.devfo.andutils.DevfoUnityPlayerActivity"
        android:label="@string/app_name"
        android:configChanges="fontScale|keyboard|keyboardHidden|locale|mnc|mcc|navigation|orientation|screenLayout|screenSize|smallestScreenSize|uiMode|touchscreen"
        android:screenOrientation="portrait">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
    </activity> 

And:

<activity android:name="com.qualcomm.QCARUnityPlayer.QCARPlayerProxyActivity" 
android:label="@string/app_name" android:screenOrientation="portrait" 
android:configChanges="fontScale|keyboard|keyboardHidden|locale|mnc|mcc|navigation|orientation|screenLayout|screenSize|smallestScreenSize|uiMode|touchscreen">
  <intent-filter>
    <action android:name="android.intent.action.MAIN" />
    <category android:name="android.intent.category.LAUNCHER" />
  </intent-filter>
</activity>

is there any way I can merge the two and get them to work from the same app? I'm using Unity 3d.

Answer 1

For example in the manifest where you want to use only the first activity as launcher you have to add this 2 modifications:

At the beginning of the manifest:

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools">

And for the activity for which you want to remove the intent filter add this code:

<activity android:name="com.qualcomm.QCARUnityPlayer.QCARPlayerProxyActivity" 
android:label="@string/app_name" android:screenOrientation="portrait" 
android:configChanges="fontScale|keyboard|keyboardHidden|locale|mnc|mcc|navigation|orientation|screenLayout|screenSize|smallestScreenSize|uiMode|touchscreen">
  <intent-filter tools:node="removeAll">
    <action android:name="android.intent.action.MAIN" />
    <category android:name="android.intent.category.LAUNCHER" />
  </intent-filter>
</activity>

The important part is to add the tools:node="removeAll" attribute in the intent-filter tag

Answer 2

Declare your manifest header like this:

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools">

And then add one of the following appropriate attributes to the relevant Activity(s):

tools:merge="override"
tools:merge="remove"
