[Q] Decompiling and building SystemUI.apk
Okay, so I am trying to get the navbar working on the Samsung Galaxy Note 3. Pretty much, I have a feeling that SystemUI is missing the icons for the navbar, which causes it to crash when the build.prop has the line "qemu.hw.mainkeys=0". The SystemUI has all the other files that were required for the S4 sysui mod, except for the icons. Being a noob at this, I went ahead and tried to add the icons, but my apk resulted in "System UI has stopped.".
So I decided maybe I am doing something wrong. So with Android Multitool for windows, I installed framework-res.apk, SystemUI.apk, and twframework-res.apk. Next I select the SystemUI.apk for decompiling, and decompile it. Then I simply select the decompiled directory (didn't modify anything!), and recompile it. I then open the new SystemUI.apk in 7z and add the META-INF and AndroidManifest.xml from the old SystemUI.apk. I then select the newly compiled SystemUI.apk for signing, then I sign it.
This is just decompiling, then building the same thing without modifications. SystemUI.apk before decompiling is 2.7 MB, the newly compiled one is only 2 MB! Something is missing out of the new one, but when I compare them in 7z, the only thing I can see that is different is the packed size; whereas the old one has files and folders that take up more space packed than the new one.
When I try doing this with just apktool and cmd, I get java errors like crazy, and the whole SystemUI.apk ends up only half decompiling.
Any idea what I am doing wrong?
