Prereq: Developer mode

Sometimes you (or someone like you) wants to develop android application on Jolla.

Even the blind 'adb logcat' might not work out of the box, it's not all bad news. Once APK is built, transfer (scp) that to device into directory: /data/app.

Now begins the interesting stuff. Shutdown alien-dalvik on command line as root:

systemctl stop aliendalvik.service

then enhance LOG settings:

export ANDROID_LOG_TAGS="*:d"

Finally start it:

systemctl start aliendalvik.service

Now alien puts out a lot of debug stuff. You can read them on device with logcat:


It's recommended not to make the change permanent into alien dalvik's scripts as there will be a lot of traces flowing.

Thanks a lot for this tip! This is exactly the information, I needed.

In order to fulfill "Prereq: Developer mode", I did

devel-su /bin/bash

And typed all those commands.

And for Sailfish X (with Android 4.4 Kitkat compatible AlienDalvik) :

chroot /opt/alien /system/bin/logcat

(To be confirmed: might also be needed for other 4.4 devices such as Jolla Tablet)
