App not installed error when using app center distribution for android

Question

Keep getting this error when I try to install the downloaded sdk. Any ideas?

The app builds and tests without errors. I get no detailed error message, only App not installed

How can I get a more detailed error message? Any ideas?

My very first build worked, so I guess it could be the version number not matching up. However, I have tried harcoding the number, still won't install:

   defaultConfig {
        applicationId "com.rgcalendar"
        minSdkVersion 16
        targetSdkVersion 22
        versionCode 23
        versionName "1.0"
        ndk {
            abiFilters "armeabi-v7a", "x86"
        }
    }

Answer 1

I was running into this issue with an App Center build on a Galaxy S8. I had tried uninstalling the app, restarting the phone and toggling the allow Unknown Sources switch, but the thing that fixed it for me was turning off Play Protect in the Google Play store. While previous builds had asked me to bypass Play Protect, this build just gave me the "App not installed" error.

To turn Play Protect off:

1. Open the Play Store
2. Tap the menu in the top left
3. Tap Play Protect
4. Turn off Scan device for security threats

You'll probably want to turn this back on if you're using a personal device.

Answer 2

From: App not installed error on android 11 device from appcenter

Re-uploading the existing keystore on appcenter has resolved the issue

Answer 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.

• The fix was suggested to me by the app center support team. They usually respond in less than 8 hours. In my case I got an answers in less than 2h since sending them the email.

Answer 4

Are you signing the build yourself? If you are, look in the app/build.gradle file.

Search for buildTypes and look at release.

Remove signingConfig signingConfigs.debug.

buildTypes {
    release {
        // Caution! In production, you need to generate your own keystore file.
        // see https://reactnative.dev/docs/signed-apk-android.
        signingConfig signingConfigs.debug // <-- REMOVE THIS LINE
        minifyEnabled enableProguardInReleaseBuilds
        proguardFiles getDefaultProguardFile("proguard-android.txt"), "proguard-rules.pro"
    }
    debug {
        signingConfig signingConfigs.debug
    }
}
