I've added Lottie to an empty rn project and get following error:

`Could not resolve all dependencies for configuration ':app:_debugApk'.

A problem occurred configuring project ':lottie-react-native'.

Guys can anyone tell me why you are updating gradle items versions?
React Native by default is using build tools 23.0.1 and so on but you updated your own to 26 and 27!
it's a painful process to update gradle versions...

I'm using the latest version of react native (0.55.4)

+1 also having the same problem. Is this forcing us to use gradle 27?
i'm using lottie-react-native v2.5.0

I had the same issue. According to this issue Could not find com.android.support:appcompat-v7:26.1.0.

In the android gradle file you need to specify the following

compileSdkVersion 26
buildToolsVersion "26.0.1"

and then find this text compile "com.android.support:appcompat-v7"
and make sure it says compile "com.android.support:appcompat-v7:26.0.1"

In your build.gradle file add maven url 'https://maven.google' should look like this

allprojects {
    repositories {
        mavenLocal()
        jcenter()
        maven {
            url 'https://maven.google.com'
        }
        maven {
            // All of React Native (JS, Obj-C sources, Android binaries) is installed from npm
            url "$rootDir/../node_modules/react-native/android"
        }
    }
}

Rebuild your project, then this problem has been solved 😄
