com.google.android.gms:play-services-ads:7.8.0 AudioManager NullPointerException

[jaredsburrows]

I have filed this issue here: https://code.google.com/p/android/issues/detail?id=182868. I do not think this is really a Robolectric issue but I wanted this to be indexed by Google so we can start documenting support here.

For now, I have gone back to 7.5.0.

I recently received this exception when upgrading from 7.5.0 to 7.8.0. The tests worked fine before.

What steps will reproduce the problem?

gradle clean assembleDebug testDebug 

Exception running Robolectric:

Encountered the same problem, which forces us to revert back to 7.5.0 for now.

@hidroh! Thanks for response and the confirmation. I wanted to document this.

It looks like this just needs a shadow for AudioManager.getMode. The real method makes an RPC call, which we don't intercept.

I also encountered the same issue, but I am not using play services...(Robolectric 3.0)

For those waiting for 3.1 release, setup your testCompile configuration like this(this is for build with GPS 7.8.0+ and testing against 7.5.0):

compile ('com.google.android.gms:play-services-ads:7.5.0') { // robolectric 3.1 needs to be released
    exclude module: 'support-v4'
    exclude module: 'support-annotations'
}
