Android-job: Proguard config

[MRezaNasirloo]

This is my service config:

       <service
            android:name="com.evernote.android.job.gcm.PlatformGcmService"
            android:exported="true"
            android:permission="com.google.android.gms.permission.BIND_NETWORK_TASK_SERVICE"
            android:process=":updater"
            >
            <intent-filter>
                <action android:name="com.google.android.gms.gcm.ACTION_TASK_READY"/>
            </intent-filter>
        </service>

proguard:
-keep class com.evernote.android.job.gcm.PlatformGcmService { *; }

exception:

Are you sure that you've added the GCM dependency?

dependencies {
    compile 'com.google.android.gms:play-services-gcm:8.4.0' // or newer
}

Also try to remove the process attribute. I've never tested to run the services with different processes and I wouldn't recommend it.

[vRallev]

Also test the proguard config with

-keep public class com.evernote.android.job.gcm.PlatformGcmService {
  public protected private *;
}

Not sure if that helps.

[MRezaNasirloo]

Thanks for response.
My bad. One of our team members accidently had deleted the compile 'com.google.android.gms:play-services-gcm:8.4.0' line from the gradle file.

[latsson]

Why does the readme for this project not mention that you need this dependency?

[vRallev]

It's optional and not required. In my own app if don't need the Google Play Services, then I wouldn't want that this library requires the Play Services

[latsson]

Well, it works for me without the dependency on Android 4.4, but I need it on Android 7.1.1, otherwise I will get Caused by: java.lang.ClassNotFoundException: Didn't find class "com.google.android.gms.gcm.GcmTaskService"

[vRallev]

I tested it this moment and don't get the exception. Does the library crash or is this just a warning? Can you add a full log?

[latsson]

Interesting, I have attached the log file. First a info/warning then it crashes.

evernote_android-job_gcm_error.txt

[vRallev]

Is it possible that you included the Play Services and switched to Firebase? Your crash looks really similar to another I saw a while ago. If yes, then this should help you. Unfortunately, there is no better way to do this.

[latsson]

Thank you I will test it! 👍 I used Firebase JobDispatcher with that dependency before, but had to switch to evernote android-job due to I don't have Google Play Services installed on all internal devices we use.

[vRallev]

That makes sense. Follow the instruction in the link and it shouldn't crash anymore.

[latsson]

There is no crash, but I can still see the ugly stacktrace coming from the following line: https://github.com/evernote/android-job/blob/1dfcca57615f80bd816bae0b8e19df04889a0d56/library/src/main/java/com/evernote/android/job/util/GcmAvailableHelper.java#L55

I can see the comment "still sometimes seeing a NoClassDefFoundError here". Do you have to log the whole throwable object? Thanks for the help.

[vRallev]

No, good idea to remove that. I'll do this as part of #165
