No Notification w/ Google Voice ~ Bounty: [$60]

[Alex9001]

Hello. Thank you for making this. I am using microg.me builds for Ether (Nextbit Robin) and I have one small problem that prevents the microg solution from being perfect.

Google Voice does not display notifications. It receives the push message, and I can verify it does so looking at microg settings > Google Cloud messaging, but it does not show a notification along with that message.

I've tried the Push Notification Tester and it works flawlessly.

Here is the logcat for the event:

I can confirm this issue.

Could this be related to #259? Specifically, I'm looking at this post from @mar-v-in: #259 (comment)

I wonder if this bug is due to microG requiring that the spec is strictly met while the Google Voice app does not do this. Google mentions this requirement in their documentation:

The permission name must exactly match this pattern—otherwise the Android application will not receive the messages.

I decompressed and looked at the AndroidManifest.xml file in the Voice app (full file here). It includes the following permissions:

<permission name="com.google.android.apps.voice.backends.gcm.permission.C2D_MESSAGE" protectionLevel="resourceID 0x2">

<uses-permission name="com.google.android.apps.voice.backends.gcm.permission.C2D_MESSAGE">

The first line in the manifest seems to say that the package should be com.google.android.apps.googlevoice:

<manifest versionCode="resourceID 0x19b7c" versionName="5.4.169585865" package="com.google.android.apps.googlevoice" platformBuildVersionCode="26" platformBuildVersionName="8.0.0">

Is microG requiring that the permission name is com.google.android.apps.googlevoice.permission.C2D_MESSAGE?

If so, perhaps this could be fixed with either of the following:

1. A temporary hack to patch the Google Voice apk or
2. A less strict interpretation of the GCM specification in microG

I expected the GCM api to be more forgiving of 3rd party apps, but I assumed official Google apps would at least meet their own specs. I suspect that the spec has become more strict over time, but Google still allowed for the deprecated naming convention for the sake of backwards compatibility. I think option 2 would be the best solution since this appears to affect multiple apps including ones from Google. Also option 2 is probably best since it would help bring the microG implementation closer to the closed source implementation. In the end, we should care about interoperability over adherence to the spec.

Edit: Used another version of the manifest file with better formatting.

Has anyone tried the hacky patching method?

may I please add +$30 to the bounty?

[Alex9001]

It isn't fake. I've never heard of bountysource and am going to paypal or BTC $50 to whoever fixed it and replied here. You can leave me a bad yelp review if I don't.

[ale5000-git]

All issues that have [$] in the title have the price already paid to Bountysource, not just promised.
Bountysource is the site where you pay the bounty, and when someone fix/implement the issue then the site will pay him/her.

[Alex9001]

I just paid $50 to bountysource. Please try to inform people rather than make claims that they are fraudulent.

[ale5000-git]

Sorry.

PS: Have you tried the latest version?

[Alex9001]

Just tried it out, unfortunately using LOS 15.1 for Ether I am unable to get Google Voice to launch. It crashes as soon as it is launched and does not show on cloud messaging in microg settings. I've tried clearing data and reinstalling from play store.

[ale5000-git]

Verify that you have microG GmsCore 0.2.5.12879 installed and post the logcat please.

[Alex9001]

I had an earlier version of microg gmscore, so I added the repo on f-droid and updated to 0.2.5.12879, then rebooted my phone, then cleared data for Google Voice, and I launched it and still had same issue (although it got a little further and showed google voice logo rather than immediately crashing).
