Removing permissions from apk

Question

I'm trying to remove permissions* from certain bank app to prevent abuse.



I've managed to download apk file using emulator (AVD) and appextractor. I've used toolapk to extract the apk file and modified AndroidManifest.xml, repacked it and signed the file using jarsigner.



The installation on my phone fails with "App not installed.". The situation is the same on fresh emulator instance (no gapps). I tried to install unmodified version of the app on emulator with the same error.



How to get a more descriptive error message?
What am I missing?



My device is Galaxy Nexus running Cyanogen mod without gapps.



*contacts & call log reading, sdcard r/w, etc...

Answer

It turns out that the installation fails because missing shared library.
Using aLogcat ROOT app from f-droid repo I was able to see following error:



E/PackageManager:( 1221): Package com.evil-bank requires unavilable shared library com.google.android.maps: failing!



One solution would be installing google maps app(or whole gapps package). I'm not going to test this one through.



Thanks to Firelord for pointing out using logcat.
