I've rupor's absolute minimal root package that among other nice features has system wide white background, which is more suitable for eInk displays than andorid's native black background.
I also use Link2SD to be able to install some apps I need. The Link2SD's background colors look ugly on system wide white background, the text on app is barely readable. I wrote to the developer on his xda thread but seems he's too busy and didn't respond. So I've decided to extract apk with apktool and changed color.xml
in /res/values folder. My understanding is that values in read should be changed to #00000000 to reflect systems white background properly. After making changes I've rebuild apk with -f option. The apk I got is smaller in size than original I don't know whether it's normal, then I've signed apk with SignApk.
Atfer installation I tried to run Link2SD and it's says invalid package. Could anybody help what's wrong?
For your convenience I've attached extracted apk folder.
