Android push notification beta crash + API issue

[mattheworiordan]

Reported by customer Edgar:

I was checking Android push notification implementation and I can't seem to subscribe to a channel after receiving the callback from 'activate'. ablyRealtime.channels.get("").push
I tried the following: ablyRealtime.channels.get("channel_name").push -- Apparently push doesn't exist. I did as the installation instructions indicate.

Also, reported a crash:

Another issue is that after executing this: ablyRealtime.push.activate(context);
The app crashes and I get:

Hi @mattheworiordan @tcard,

Any updates on this? Can I help with something?

[mattheworiordan]

@itolisto sorry for not replying. I will remind @tcard to look into this.

[itolisto]

Thank you @mattheworiordan and @tcard.

[tcard]

Hi @itolisto! I'm currently working on this. I'll get a solution out as soon as possible. Sorry for the delay!

[paddybyers]

@tcard is it a proguard.txt issue? Any class that's loaded by name (eg with a Class.forName()) needs to be excluded from the name minimisation/obfuscation.

[tcard]

@paddybyers They're loaded with plain imports, but even then I've tried a number of changes to proguard.txt and still doesn't work.

[tcard]

@itolisto I've updated our push branch and the instructions at #308. Could you please try again with that?

[itolisto]

@tcard I'm following the build instructions properly but I'm getting an error.

Here's the stack trace:

@itolisto Sorry, that should be fixed now too. I committed some code that I shouldn't have! And I didn't catch the compilation error myself since I do have the missing files outside of the commit.

[itolisto]

@tcard No worries, I'll try it right away! I'll let you know the result in a few minutes

[itolisto]

@tcard It's now compiling without problem but I'm still not able to see the 'push' parameter. Take a look:

And this is how my build.gradle file looks like:

Am I doing something wrong?
