I'm trying to pull an APK file, modify it, then re-install to phone. I'm using adb, apktool and jarsigner. I'll call the APK file, 1.arm64_v8a.apk.

adb pull /data/ .. /1.arm64_v8a.apk to pull the file from android to my computer.
apktool decode 1.arm64_v8a.apk -o 1.arm64_v8a to decompress the APK
apktool build --use-aapt 1.arm64_v8a -o 1.arm64_v8a.apk to build a new APK.
sign apk jarsigner -verbose -sigalg SHA1withRSA -digestalg SHA1 -keystore keystore 1.arm64_v8a.apk mykey
Install APK to phone adb install 1.arm64_v8a.apk which produces: Failure [INSTALL_FAILED_INVALID_APK: Failed to extract native libraries, res=-2]

Did you tried adding "--use-aapt2" instead of "--use-aapt"? – emandt Nov 04 '21 at 15:01
@emandt Tried aapt and aapt2 - no luck. – James Welchman Nov 04 '21 at 15:18
Did you tried to open resigned APK using a decompressing software (i.e: 7zip) from your PC? Is it still working? Try also this: https://stackoverflow.com/questions/55173004/targeting-sdk-android-q-results-in-failed-to-finalize-session-install-failed-i – emandt Nov 04 '21 at 15:26
@emandt - yup. Extracted the new apk using Linux unzip. Everything seem correct. – James Welchman Nov 04 '21 at 15:36
