Targeting SDK Android Q results in Failed to finalize session : INSTALL_FAILED_INVALID_APK: Failed to extract native libraries, res=-2

Question

Once I switch my target api to 'Q' I cannot install the APK on Android Q Emulator. I get error:

Failed to finalize session : INSTALL_FAILED_INVALID_APK: Failed to extract native libraries, res=-2

Android Studio (v3.3.2) recommends I uninstall apk first. I tried uninstalling apk and I still get the same error. App work if I downgrade target api to 28.

Answer 1

This happens because of an issue with zipalign, see - https://issuetracker.google.com/issues/37045367. You need to set extractNativeLibs in your Application Tag on AndroidManifest.xml

<application
        android:allowBackup="false"
        android:label="@string/app_name"
        android:extractNativeLibs="true"
...
>

If you are using adb to install the apk try adding -t flag

adb install -t <path-to-apk>

Answer 2

If you want android:extractNativeLibs="false", use zipalign with -p key in order to page align ELFs within ZIP:

zipalign -p 4 app.apk app-aligned.apk
