applicationId manifest placeholder for multiple build flavors not working

Question

I am modifying current android project so it can be installed on same device for multiple flavors and build configs.

build.gradle:

{
    // ...
    defaultConfig {
        applicationId "com.myapp"
        manifestPlaceholders = [
            manifestApplicationId: "${applicationId}",
            onesignal_app_id: "xxxx",
            onesignal_google_project_number: "xxxx"
        ]
    // ...
    }

    productFlavors {
        production {
            applicationId "com.myapp"
            // ...
        }

        dev {
            applicationId "com.myapp.dev"
            // ...
        }

        // ...
    }

    buildTypes {
        release {
            // ...
        }

        debug {
            applicationIdSuffix ".debug"
            // ...
        }
    }

    // ...
}

AndroidManifest.xml:

<manifest ... >
    <uses-permission android:name="${applicationId}.permission.C2D_MESSAGE" />
    <permission
    android:name="${applicationId}.permission.C2D_MESSAGE"
    android:protectionLevel="signature" />      
    <!-- ... -->

    <receiver
        android:name="com.onesignal.GcmBroadcastReceiver"
        android:permission="com.google.android.c2dm.permission.SEND" >
        <intent-filter>
            <action android:name="com.google.android.c2dm.intent.RECEIVE" />
            <category android:name="${applicationId}" />
        </intent-filter>
    </receiver>

    <!-- ... -->
</manifest>

When I compile both debug and release version of the same flavor, I got error message:

...

INSTALL_FAILED_DUPLICATE_PERMISSION

perm=com.myapp.permission.C2D_MESSAGE

pkg=com.myapp.dev

...

manifestApplicationId placeholder came from AndroidManifest.xml on OneSignal library as instructed on https://documentation.onesignal.com/docs/android-sdk-setup

Anybody have a clue how to fix this problem? Thank you.

Answer 1

OneSignal requires the manifestPlaceholders key manifestApplicationId to be set to your applicationId (AKA your package name).

This can be done by setting it in your buildTypes like the following.

buildTypes {
   debug {
      defaultConfig {
         manifestPlaceholders = [manifestApplicationId          : "${applicationId}",
                                 onesignal_app_id               : "11111111-1111-1111-1111-111111111111",
                                 onesignal_google_project_number: "111111111"]
       }
   }

   release {
      defaultConfig {
         manifestPlaceholders = [manifestApplicationId          : "${applicationId}",
                                 onesignal_app_id               : "22222222-2222-2222-2222-222222222222",
                                 onesignal_google_project_number: "222222222"]
      }
   }
}

Update 1: OneSignal-Android 3.3.0 no longer requires manifestApplicationId.

Update 2: OneSignal-Android 4.0.0 no longer requires any manifestPlaceholders values. Instead OneSignal.setAppId(ONESIGNAL_APP_ID) needs to be called at runtime.
