How to fix App not installed error in Android

Question

I develop android application and when create APk from this application (with Generate Signed APK) and when install this apk in other devices not install and show me this error on phone : App not installed

how can i fix it?

Solution 1

This is usually caused when you have a debug apk that is signed with a different certificate and you are trying to install a release version with a different certificate. If you have a debug apk on the device try uninstalling it and try again.

Solution 2

For me, **disabling Google Play Protect** options from play store app worked , and i was able to get rid of the App not Installed error. Check the play protect option available in Google Play Store Navigation menu.

Solution 3

android:extractNativeLibs="true"

in AndroidManifest.xml file fixed the problem for me.

    <application
        // ...
        android:extractNativeLibs="true"

Notes: I got this error when building with App Center and all the signing was handled by app center.

For easier debugging just drag and drop the apk file in the android emulator. Your will get a more detailed message why the app is not installed.

Previously I tried all the Play protect things and checked the build.gradle file contains no release info in signingConfigs and that there's no signingConfig in buildTypes.release just as described in the other answers from this page.

Solution 4

delete build folder from your project and then build project again.. working for me

This seemed to work for me. I am trying to understand the drawback of this, if any? It seems like all this does is compress your native libs, but I can't tell if this has any unwanted side affects

This fix was recommended to me by AppCenter support team. I found more about this here: stackoverflow.com/questions/42998083/…
