Getting "verifyReleaseResources" error after upgrading React Native

Question

I'm trying to upgrade an application to React Native 0.57.1. I think I've followed all the steps, upgraded all the right files, yet I'm still getting an error that I cannot understand:

:react-native-document-picker:compileReleaseSources UP-TO-DATE

error: failed linking references.
:react-native-document-picker:verifyReleaseResources FAILED

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':react-native-document-picker:verifyReleaseResources'.
> com.android.ide.common.process.ProcessException: Failed to execute aapt

I can't really make sense of these errors, any idea what they mean? How can I find out how to fix this?

I've tried various things, including deleting the .cache directory, changing the gradle version but nothing seems to help. Any idea?

Answer 1

You need to add following code in your project's android/build.gradle:

subprojects {
    afterEvaluate {project ->
        if (project.hasProperty("android")) {
            android {
                compileSdkVersion 27
                buildToolsVersion "27.0.2"
            }
        }
    }
}

Answer 2

For me, what fixed the issue was prefixing with app

./gradlew app:assembleRelease

Answer 3

Reason for the error:

You have installed react-native-document-picker as a dependency, And the reason for this error is that the configurations of your android/app/build.gradle and node_modules/react-native-document-picker/android/build.gradle mismatch.

Solution

1. Navigate to node_modules/react-native-document-picker/android/build.gradle
2. Edit and keep the compileSdkVersion buildToolsVersion minSdkVersion targetSdkVersion same as you have in android/app/build.gradle
3. Sync the project again.
4. Run ./gradlew assembleRelease from the terminal.
