Android Auto Setup with Gradle Build Flavors
I have a project where I am attempting to add Android Auto support. I have added the following code to my manifest as shown in the Auto documentation:
<application
....
<meta-data android:name="com.google.android.gms.car.application"
android:resource="@xml/automotive_app_desc"/>
....
<service
android:name="com.me.auto.MyMediaBrowserService"
android:exported="false">
<intent-filter>
<action android:name="android.media.browse.MediaBrowserService" />
</intent-filter>
</service>
....
</applicaiton>
I'm also using different build flavors, defined in my gradle.build file:
defaultConfig {
applicationId "com.me"
minSdkVersion 16
//noinspection OldTargetApi
targetSdkVersion 22
versionCode 1
versionName "1.0"
}
productFlavors {
regular {
applicationId "com.me"
}
different {
applicationId "com.meother"
}
}
When I build and install using the 'regular' flavor, android auto does not work. However, when I build and install using the 'different' flavor, everything works great. If I then change the regular applicaitonId to something else like 'com.menew', again Auto works great.
How is the applicationId in the build flavor making or breaking Android Auto functionality?
I am not absolutely sure, but I would guess this is related with the application id, eg you can make avoid full qualified package names by using the relative names you can use it in the manifest all all places. Check this:
<service
android:name="com.me.auto.MyMediaBrowserService" ...>
vs.
<service
android:name=".auto.MyMediaBrowserService" ...>
Make also sure that you have no hard coded packages in your code always use BuildCondig.APPLICATION_ID when you need your package name.
Looks like you have it mostly right. I would recommend these changes (based on https://developer.android.com/training/auto/audio/index.html) and see if this fixes it.
1) Remove the package name so it's not locked into one flavor. Alternatively, you can use ${applicationId} and gradle will insert the correct one.
2) Set the service to be exported ( android:exported=true ).
<application
....
<meta-data android:name="com.google.android.gms.car.application"
android:resource="@xml/automotive_app_desc"/>
....
<service
android:name="${applicationId}.auto.MyMediaBrowserService"
android:exported="true">
<intent-filter>
<action android:name="android.media.browse.MediaBrowserService" />
</intent-filter>
</service>
....
</applicaiton>
Did you try to create a flavorDimensions?
You can try this.
flavorDimensions "mode"
productFlavors {
regular {
dimension = "mode"
}
different {
dimension = "mode"
}
}
if you want to get the version of your application
if (BuildConfig.Flavor.contains("regular") || BuildConfig.Flavor.contains("different")) {
// Your code goes here.
}
Hope this will help.
