Error when trying to run my React Native app on Android

Question

I've built my React Native app and tested and troubleshooted with my iOS devices for months. Now I'm trying to built and test the app on Android for the first time. The thing is, that I keep getting errors trying to run the Android-version of my app. After hours of debugging and troubleshooting, I tried to create a new RN project and see if that could run on my emulator and device. I got that part working and then I wanted to copy/paste the files of my existing app project into the new project.

I pasted my existing assets, styles, the source JS-files and the package.json file into the new project, ran npm install and then I ended up with the exact same error message as I had in the original project when I run react-native run-android.

The full error message is here:

error Failed to install the app. Make sure you have the Android development environment set up: https://reactnative.dev/docs/environment-setup.
Error: Command failed: ./gradlew app:installDebug -PreactNativeDevServerPort=8081

Please let me know if you know what to do or if you have experienced a similar issue!

Answer 1

I've hit this same issue and have temporarily resolved it by uninstalling react-native-video (npm uninstall --save react-native-video). That's not a great answer as I need that component, but I don't have a full solution yet. I think somehow com.yqritc:android-scalablevideoview:1.0.4. is required by react-native-video but has gotten lost or removed. Other thoughts are welcome.

UPDATE: Resolved! In your build.gradle in your Android folder you need to add the repository "jcenter()" in allprojects (not in build dependencies) like this...

allprojects {
    repositories {
        mavenCentral()
        mavenLocal()
        jcenter()
}

Answer 2

It's best to only pull specific packages from jcenter() in android/build.gradle:

allprojects {
    repositories {
        .... # Keep the rest
        jcenter() {
            content {
                includeModule("com.yqritc", "android-scalablevideoview")
            }
        }
    }
}

Answer 3

Because jCenter is removed from latest react native and com.yqritc:android-scalablevideoview is only published there you need to add jCenter again as a repository but I would advice to define the package so other dependencies are not fetched/taken from jCenter anymore. Because jCenter does not allow any updates anymore of any package all other packages should be taken from mavenCentral for example.

You can add jcenter to android/build.gradle like this:

allprojects {
    repositories {
        .... # Keep the rest
        jcenter() {
            content {
                includeModule("com.yqritc", "android-scalablevideoview")
            }
        }
    }
}
