Installation on SailfishOS AlienDalvik

[vermut]

Having rooted system I invoke installer. I see it changing app_process and deploying XposedBridge.jar, installer also sees them installed after reboot and reports correct versions but still displays "not installed" message.

Where can I look next?

[rovo89]

Please provide more details. The Xposed log from the installer would be good for a start.

Not sure where to find one. data dir has no logs

[root@Jolla opt]# cd ./alien/data/data/de.robv.android.xposed.installer
[root@Jolla de.robv.android.xposed.installer]# find

Attaching logcat entries from installation

Is that after restarting the device? If yes, please try to get a logcat of the early boot. ls -l /system/bin might be also be helpful to ensure that the files are replaced properly.

Is this OS even an Android variant? On Wikipedia, I read: "Sailfish OS can run Android applications through a proprietary compatibility layer."

Xposed can run on ROMs which are slightly modified compared to AOSP, but this sounds more like they have built their own OS with just some parts of Android integrated. The fact that /system is placed in /opt/alien already looks strange.

Is app_process even executed on that ROM? How confident are you that the Dalvik runtime is (mostly) unmodified? It's not open-source, is it?

[vermut]

The OS itself is linux which includes proprietary version of Dalvik called alien-dalvik. So it's not the pure Android. But most of the Android apps run there and some of the hacks work.

But app_process is not executed. I renamed it and it still works fine. As I understand it's completely crucial part of whole framework? Can Xposed be injected somewhere else? What should I look for to find alien-analogue of usual app_process?
