Two flavors of the app on the same device [duplicate]

Question

I have created two separate apps using Google Play Developer Console:

• "MyApp" with ID com.myname.app (for prod flavor)
• "MyApp Stage" with ID com.myname.appStage (for stage flavor)

I deploy these flavors to the corresponding beta channels using com.github.triplet.play task in gradle.

When I try to install both flavors on the same device, the Google Play gives me error: -505. If I uninstall the first installed version, then I can successfully install the second one.

As I can see in this tutorial, it should be enough.

Any ideas what's wrong?

Here is my gradle script fragment:

def getGoogleApiJsonFile() {
    (...)
}
android {
    (...)

    defaultConfig {
        applicationId "com.myname"
        (...)
    }
    buildTypes {
        release {
            (...)
            signingConfig signingConfigs.release
        }
    }
    productFlavors {
        prod {
            applicationIdSuffix '.app'
        }
        stage {
            applicationIdSuffix '.appStage'
        }
        dev {
            applicationIdSuffix '.appDevelop'
            (...)
        }
    }
    play {
        jsonFile = getGoogleApiJsonFile()
        track = 'beta'
    }
    (...)
}

And here are some fragments of the AndroidManifest.xml:

            </intent-filter>
        </activity>
        (... more activities here ...)
        <provider
            android:authorities="com.myname.fileprovider"

            android:exported="false"
            android:grantUriPermissions="true">
            <meta-data
                android:name="android.support.FILE_PROVIDER_PATHS"
                android:resource="@xml/file_provider_paths"
                />
        </provider>

        (... meta-data for io.fabric.ApiKey here...)

    </application>

</manifest>
