Failed to install the app. Make sure you have the Android development environment set up: https://reactnative.dev/docs/environment-setup

Hi,

I'm a participant to the ONTOCHAIN ecosystem batch n°3. I'm trying to get the app running locally, so I can then integrate that feature into the Startin'blox framework.

I fail however to install it on my phone. When I issue the following command:

yarn android --verbose

I get:

yarn run v1.22.19
$ react-native run-android --verbose
info Running jetifier to migrate libraries to AndroidX. You can disable it using "--no-jetifier" flag.
Jetifier found 1037 file(s) to forward-jetify. Using 8 workers...
info Starting JS server...

debug Running command "cd android && ./gradlew app:installDebug -PreactNativeDevServerPort=8081"

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 with exit code 1.

I've ensured I had Android Studio installed and that adb is on my $PATH. When I type:

adb devices

I get:

List of devices attached
5f0834b9    device

I followed the https://reactnative.dev/docs/environment-setup link but to no avail.

Can you help me?

Hi Alex, Thanks for your message.

To compile the project, please follow the next steps:

1. Clone

2. Install & run nodeify

yarn install
yarn nodeify

3. Change gradlew permissions

chmod 755 android/gradlew

4. Add extra config to the rn-did-siop-example-app/android/build.gradle file

allprojects {
  ...
  configurations.all {
    resolutionStrategy {
      force "com.facebook.react:react-native:0.65.1"
    }
  }
...

5. Build the project

yarn android

In case you are still gettings errors during the build build process, run the following commands:

npx jetify
yarn android

or

yarn android --no-jetifier

Let me know! Charlie

Thank you for your response @cfontana0

Here is my build.gradle file:

allprojects {
    repositories {
        mavenCentral()
        mavenLocal()
        maven {
            // All of React Native (JS, Obj-C sources, Android binaries) is installed from npm
            url("$rootDir/../node_modules/react-native/android")
        }
        maven {
            // Android JSC is installed from npm
            url("$rootDir/../node_modules/jsc-android/dist")
        }

        google()
        jcenter()
        maven { url 'https://www.jitpack.io' }
    }
    configurations.all {
      resolutionStrategy {
        force "com.facebook.react:react-native:0.65.1"
      }
    }
}

Here is what I get when I run yarn android:

yarn run v1.22.19

I'm not sure what to set the ANDROID_SDK_ROOT environment variable at. Do you know?

I'm on MacOS if that helps

@happy-dev : does that Stack-overflow answers helps: https://stackoverflow.com/questions/29391511/where-is-android-sdk-root-and-how-do-i-set-it/48957437#48957437 ?

Answer specific to MacOS but just a guess as I do not know anything about Android development. Looks like it is a global environment variable though.

@balessan Ah ah, I'm happy you're here Can you take over here?

You'll be much more productive than me I tried to move forward as much as possible without bothering you but I have to face this harsh reality that... it probably works better when you do it. I'm officially only good at doing Google Slides... That's a bit hard to take

Call me if you need some directions here but I was trying to install this app to have a concrete code implementation running locally.

My plan was then to dig into the code and figure what needs to be added to Startin'blox in order to become GimlyID compatible. Writing this, I realize how naive I was to think I'll manage to do all this on my own ☺️

Hi @happy-dev sorry that I didn't back to you early.

Were you able to manage it?
