The apk rebuild by apktool can not be installed even after zipalign and sign

Question

I need to make hundreds flavors of my app. They have different logos and names. When I use android studio's productFlavor, it always OOM, and cost very long time to build hundreds app. So I want to make these apps by apktool. decompile, rebuild, zipalign, apksign. But I find that, the finally generated apk can not be installed. The error is:

Failure [INSTALL_FAILED_INVALID_APK: ed to extract native libraries, res=-2]

apktool d my_app.apk decompile

change the logo and name.

apktool b decompile my_app-rebuild.apk

zipalign -v 4 my_app-rebuild.apk my_app-align.apk

apksigner sign --ks my_key.jks --ks-pass pass:my_ks_pass --key-pass pass:my_key_pass --v1-signing-enabled true --v2-signing-enabled true --out my_app_out.apk my_app-align.apk

After these works, the my_app_out.apk can not installed.

Answer 1

From the error you got:

Failure [INSTALL_FAILED_INVALID_APK: ed to extract native libraries, res=-2]

If set to false, then your native libraries must be page aligned and stored uncompressed in the APK.

It's either you need to set extractNativeLibs flag to true or you need to page align the apk when doing zipaligning by adding -p parameter:

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

The zipalign command should be:

zipalign -p -v 4 my_app-rebuild.apk my_app-align.apk
