react-native: Task 'installRelease' not found in root project

I was able to run manually: cd android && gradlew assembleRelease, but it’s outputting app-release-unsigned.apk.

Edit: It appears I was missing signingConfig in buildTypes > release. See example below:

...
android {
    ...
    defaultConfig { ... }
    signingConfigs {
        release {
                storeFile file(MYAPP_RELEASE_STORE_FILE)
                storePassword MYAPP_RELEASE_STORE_PASSWORD
                keyAlias MYAPP_RELEASE_KEY_ALIAS
                keyPassword MYAPP_RELEASE_KEY_PASSWORD
        }
    }
    buildTypes {
        release {
            ...
            signingConfig signingConfigs.release
        }
    }
}
...

i have the same issue

Still Happens on 0.55.2

@Manoj002 Have you updated your android/app/build.gradle file to include the signingconfigs and then signingConfig signingConfigs.release inside of the buildTypes?

@segheysens , thanks for your response mate i got it working by updating the gradle and by properly following the docs again! though thanks mate!

hello people, i tried @BuffMcBigHuge solution but still getting same error Task ‘installRelease’ not found in root project ‘android’. Some candidates are: ‘installDevRelease’. i did everything as mentioned in docs, but i guess still missing out something

Works for me

As @BuffMcBigHuge said, the problem is the missing singinConfig in gradle files. You have to proper configure it as described in https://facebook.github.io/react-native/docs/signed-apk-android.html and the installRelease will work.

        proguardFiles getDefaultProguardFile("proguard-android.txt"), "proguard-rules.pro"

        signingConfig signingConfigs.release
    }
}

//…`

e no android/gradle.properties ` MYAPP_RELEASE_STORE_FILE=my-release-key.keystore

MYAPP_RELEASE_KEY_ALIAS=my-key-alias

MYAPP_RELEASE_STORE_PASSWORD=****

MYAPP_RELEASE_KEY_PASSWORD=**** `

Thanks for posting this! It looks like you may not be using the latest version of React Native, v0.53.0, released on January 2018. Can you make sure this issue can still be reproduced in the latest version?

I am going to close this, but please feel free to open a new issue if you are able to confirm that this is still a problem in v0.53.0 or newer.

In addition to @BuffMcBigHuge , I also made the silly mistake of having my-release-key.keystore in [myApp]/android rather than [myApp]/andriod/app
