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

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>

I also got this error in AWS Device Farm. Turns out they have sdk version 21 installed and my minSdkVersion was set to 24. Lowering my minSdkVersion to 21 resolved this. This error was getting returned on trying to install apk on the test device. Hope this helps for anyone else setting up device farm on android.

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
