I'm getting this errors building the an Android app:

Same issue ... :(

I had the same issue, anyone has solution?

[Sebastien-Lampazona]

Hey, i have upgraded Android version in the build.gradle of the project, and the issue was resolved ...

Maybe a fix will arrive ?

[giovanicascaes]

@skymax406 what exactly did you do?

[Sebastien-Lampazona]

This is my react-native-blur/android/build.gradle file :

buildscript {
    repositories {
        google()
        jcenter()
        maven {
            url 'https://maven.fabric.io/public'
        }    }

    dependencies {
        classpath 'com.android.tools.build:gradle:3.2.1'
    }
}

apply plugin: 'com.android.library'

android {
    compileSdkVersion 28
    buildToolsVersion "28.0.3"

    defaultConfig {
        minSdkVersion 16
        targetSdkVersion 28
        versionCode 1
        versionName "1.0"

        renderscriptTargetApi 23
        renderscriptSupportModeEnabled true
    }
    lintOptions {
        abortOnError false
    }
}

repositories {
    google()
    mavenLocal()
    jcenter()
}

dependencies {
    implementation "com.facebook.react:react-native:+"
}

Maybe check you have android.enableAapt2=false in your android/gradle.properties, it's a workaround, not a fix

I updated the build.gradle of react-native-blur (https://github.com/react-native-community/react-native-blur/blob/master/android/build.gradle#L14), and I put the same SDK and build tool version as mine, which is 28. I don't know what it takes to update the SDK version of this library, does bumping the SDK version of react-native-blur from 25 to 28 break anything? AFAIK it builds and it works on my project using SDK v28.

[engineering-addict]

This should solve the problem (just add to your android/build.gradle):

buildscript {...}

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

In my case, I had to use it like this

      if(project.hasProperty("android")) {
          android.compileSdkVersion = rootProject.ext.compileSdkVersion
          android.buildToolsVersion = rootProject.ext.buildToolsVersion
       }
