android:extractNativeLibs="false" #10

Closed ale5000-git closed 5 years ago

ale5000-git commented 6 years ago

Does it support apk files with android:extractNativeLibs="false"? In this case also the binary libraries must be stored uncompressed and zip-aligned.

patrickfav commented 6 years ago

Hi ale5000,

I'm not familiar with android:extractNativeLibs. Could you elaborate why it would be an issue with the signer? I basically use the first party tools/signing chain as provided by google (apk-signer & zipalign), so I'm not sure how to influence binary libs.

ale5000-git commented 6 years ago

Normally resources are stored uncompressed and zip-aligned so they can be used directly from the archive without extraction instead the binary libraries are extracted by Android on apk installation.

If android:extractNativeLibs="false" is set then binary libraries aren't extracted and they get the same treatment of resources.

I just want to know if it zip-align also binary libraries in addition to resources. PS: There is a flag (that now don't remember) to tell zipalign to align also libraries.

The only "odd" param I could find for https://developer.android.com/studio/command-line/zipalign is 

-p : outfile.zip should use the same page alignment for all shared object files within infile.zip

As you can see I use the tool without any additional options https://github.com/patrickfav/uber-apk-signer/blob/ecc74783b156e2a1f729945a9902b6ad71fc6729/src/main/java/at/favre/tools/apksigner/SignTool.java#L244 If you want this checked I suggest you just try it out, I do not have an APK by hand with this specific build setup. I would very much appreciate a feedback/pull request if there is anything to fix.

I'm not at home currently, but if you need an apk to test there is this: https://microg.org/fdroid/repo/com.google.android.gms-12221403.apk

Using your provided APK, no matter how I use zipalign, I cannot align it and verify:

The only option I can see which may influence this is '-p', but it makes no difference. Any idea?

@ale5000-git Any idea? If your apk wont align, Im afraid theres not much I can do.
