Android Facebook Content Provider Authority

I'm developing an app with (at least) two flavors having different package names - therefore actually two different apps as far as the android system is concerned. The app uses Fa

Solution 1:

One of the possible solutions I have found is the one described here

http://gradlewhy.ghost.io/overcoming-install-failed-conflicting-provider/

I am already using this for (debug/release variants) android.support.v4.content.FileProvider and as far I have tested also works for com.facebook.app.FacebookContentProvider.

Just add into apps build.gradle

    debug {
        applicationIdSuffix '.debug'
        versionNameSuffix '-DEBUG'

        resValue "string", "fb_provider_id", "com.facebook.app.FacebookContentProvider{app_id_1}"
    }

    release {
        minifyEnabled true
        shrinkResources true
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'

        resValue "string", "fb_provider_id", "com.facebook.app.FacebookContentProvider{app_id_2}"
    }

and then in the AndroidManifest

<providerandroid:authorities="@string/fb_provider_id"android:name="com.facebook.FacebookContentProvider"android:exported="true"/>

Solution 2:

I was able to solve this by having separate manifests for my debug and release flavors and in my debug flavor manifest, I added the snippet for the provider but set the exported value to false. In my release flavor manifest, I have the original provider snippet with exported set to true.

After I did this, I no longer got the INSTALL_FAILED_CONFLICTING_PROVIDER error.

<providerandroid:authorities="com.facebook.app.FacebookContentProvider{app id here}"android:name="com.facebook.FacebookContentProvider"android:exported="false"/>

Solution 3:

<providerandroid:authorities="com.facebook.app.FacebookContentProvider{app id here}"android:name="com.facebook.FacebookContentProvider"android:exported="false"/>

exported can be "true"

Solution 4:

If your have one project and multiple flavors(means: multiple apps with minor tweaks) like me, you can

1.create multiple facebook app (from https://developers.facebook.com/apps/)

2.add codes for correspoding flavor

3.add facebook_app_id string value in the corresponding flavor's folder.

Example:

app/build.gradle

...
flavorDimensions "regular"

productFlavors {
    flavour_name {
        dimension "regular"
        resValue "string", "authority", "com.facebook.app.FacebookContentProvider123456789"
    }

app/src/main/AndroidManifest.xml

<meta-dataandroid:name="com.facebook.sdk.ApplicationId"android:value="@string/facebook_app_id"/><providerandroid:authorities="@string/authority"android:name="com.facebook.FacebookContentProvider"android:exported="true" />

app/src/flavour_name/res/values/string.xml

<string name="facebook_app_id" translatable="false">123456789</string>
