Questions about porting original apks

[xingrz]

Hi Zhuowei,

I'm trying to port the original GlassHome.apk into my cellphone, these are what I did:

1. Removed <uses-library> section (com.google.android.glass requirement) in AndroidManifest.xml because original Android does not have glass-core.odex or glass-services.odex
2. Merged *.smali files of glass-core.odex and glass-services.odex (library com.glass.android.glass) into GlassHome because GlassHome actually need them
3. Copied fonts from ROM's /system/fonts into assets/fonts
4. Copied native jni *.so library files needed (grep -r loadLibrary) into lib/armeabi-v7a
5. apktool b all stuffs above
6. Signed the apk, and installed it successfully

Everything seems fine, but Glass Home can't run actually.

Is it something I just missed?

[zhuowei]

There's a call to a nonexistant view method that needs to be removed: see the commit logs for the GlassHome repo. https://github.com/zhuowei/Xenologer-src-glasshome/commit/da0ee7936c109ef2a3b1a0fae79e8488eeca6e20

@zhuowei do you meen getDeviceTapTimeout ? I've grep -r it and it seems gone since XE11.

[xingrz]

@zhuowei The apk crashes repeatly and I've checked adb logcat and I found it's probably due to a permission leak android.permission.WRITE_SECURE_SETTINGS.

Is it due to the signature? What key should I use to sign the apk?

[zhuowei]

Did you remove the turn off screen calls?

[xingrz]

@zhuowei ooops...you meens patching the smali/com/google/glass/util/PowerHelper.smali? not yet. I'll try tomorrow, so late, sleep...

[xingrz]

oops...

[zhuowei]

You're still missing some fonts - can you check the RobotoTypefaces class and see if font loading was changed?

[xingrz]

oops...my mistake, I shipped /system/fonts rather than /system/glass_fonts.

W/ActivityManager(  410):   Force finishing activity com.google.glass.home/.timeline.MainTimelineActivity

mmmmmh....a step closer to success, but still crashes :(

[xingrz]

    public static TimelineHostManager get()
    {
        if(sInstance == null)
            sInstance = new TimelineHostManager(ITimelineManager.Stub.asInterface(ServiceManager.getService("timeline")));
        return sInstance;
    }

after digging into com.google.android.glass.timeline.TimelineHostManager (which is originally /system/framework/glass-core.odex and I merged its smalis into GlassHome's), it seems caused by ServiceManager.getService("timeline") returned null

[zhuowei]

We might have to fix that - we could try running the timeline host as a Service in an APK; I'll try working on that this weekend. Then, you'll probably need to change the calls so they bind to the app instead of checking the context.

That way, though, means that any apps developed with the Glass GDK would crash instantly with Xenologer - any ideas?

[xingrz]

Thanks. I'm not very familiar with system framework. Waiting for your good news :+1:

[zhuowei]

So the code for the glass service is in frameworks/glass-services.odex; if you deodex that and glass-core.odex, build an APK with a Service exposing the timeline manager, and finally modify the code in the Glass APKs to use that instead, it should work without root.

[xingrz]

I checked com.google.android.glass.timeline.TimelineService in frameworks/glass-services.odex, it is extends from ITimelineManager.Stub which is a Binder.

Since I'm not very familiar with system-level stuffs, I have no idea about how to port the TimelineService to a app-level Service. Would you provide some idea?

[zhuowei]

This is beyond my abilities as well, I'm afraid. Maybe just dex2jar the glass-core and glass-services, include them in an APK. and have a Service returning the timeline manager instance as a Binder?

I have no experience with writing Services, so I can't really help you here :(

[xingrz]

Thanks for inspiring me. Since the platform is getting better uncoupled, more features are separated from the GlassHome.apk and leading the porting gets more difficult. But luckily it's more easier to get an actual Glass today.

Anyway, should we close this issue?
