Got it, let's walk through exactly how to strip every trace of Fabric from your AndroidManifest.xml after deleting all the related files in your Unity project. Here's a step-by-step breakdown:

• Locate your AndroidManifest.xml first: In Unity, this is usually stored in Assets/Plugins/Android. If you're using Unity's auto-generated manifest, modify the custom one in this folder—Unity's manifest merger will prioritize this over default entries.

• Delete Fabric meta-data entries: Look for lines like these inside the <application> tag and remove them entirely:

  <meta-data android:name="io.fabric.ApiKey" android:value="YOUR_API_KEY"/>
  <meta-data android:name="io.fabric.ApiSecret" android:value="YOUR_API_SECRET"/>
  

• Remove Fabric-specific components: Scan the <application> tag for any activities, services, or providers linked to Fabric/Crashlytics. Common examples include:

  • <activity android:name="com.crashlytics.android.CrashlyticsActivity" .../>
  • <service android:name="com.crashlytics.android.core.CrashlyticsBackgroundService" .../>
  • <provider android:name="com.crashlytics.android.CrashlyticsInitProvider" .../>
    Delete any of these you find.

• Clean up permissions (if needed): Fabric typically uses standard permissions like INTERNET or ACCESS_NETWORK_STATE, which other parts of your app might still rely on. Only remove permissions if you’re 100% sure they were added exclusively for Fabric (you’ll spot these if the permission name includes io.fabric or crashlytics).

• Handle stubborn merged entries: If after cleaning your custom manifest, you still see Fabric references in the final merged manifest (check Unity's build output or Android Studio to verify), use the tools:node="remove" trick to force deletion. First, add the tools namespace to your manifest root if it’s missing:

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

  Then add entries for any lingering Fabric elements, like:

  <meta-data android:name="io.fabric.ApiKey" tools:node="remove"/>
  <provider android:name="com.crashlytics.android.CrashlyticsInitProvider" tools:node="remove"/>
  

• Final cleanup: After editing the manifest, delete Unity's Library folder to clear cached build data, then rebuild your project. This ensures no leftover Fabric config is hiding in cached files.
