Android Facebook content provider authority-ThrowExceptions

Exception or error:

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 Facebook sharing, so I have the provider declared in the manifest:

<provider android:authorities="{app id here}"

This is done according to Facebook’s instructions:

This works fine with one app, but trying to install the second app on the same device fails with the error INSTALL_FAILED_CONFLICTING_PROVIDER. This is the only provider defined in the manifest so I’m pretty sure it’s the problem. If I change the provider string to be something different it crashes when attempting to open a Facebook share dialog.

I’ve seen claims that it’s possible to use the same Facebook app in multiple android apps, but can’t find anything in Facebook’s documentation about it. Has anybody done this, and how did you get around the provider authority problem? Thanks.

How to solve:

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.

<provider android:authorities="{app id here}"


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

I am already using this for (debug/release variants) and as far I have tested also works for

Just add into apps build.gradle

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

        resValue "string", "fb_provider_id", "{app_id_1}"

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

        resValue "string", "fb_provider_id", "{app_id_2}"

and then in the AndroidManifest

<provider android:authorities="@string/fb_provider_id"


<provider android:authorities="{app id here}"

exported can be “true”


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

1.create multiple facebook app (from

2.add codes for correspoding flavor

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



flavorDimensions "regular"

productFlavors {
    flavour_name {
        dimension "regular"
        resValue "string", "authority", ""


  <meta-data android:name="com.facebook.sdk.ApplicationId"

<provider android:authorities="@string/authority"
        android:exported="true" />


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