Unable to build react-native app on Android device :failed to find target with hash string 'android-23'

Question

Here is the full error: failed to find target with hash string 'android-23' in: /Users/username/Library/Android/sdk

This is the build.gradle file in my android/app:

android {
    compileSdkVersion 23
    buildToolsVersion "23.0.1"

    defaultConfig {
        applicationId "com.mobile"
        minSdkVersion 16
        targetSdkVersion 22
        versionCode 1
        versionName "1.0"
        ndk {
            abiFilters "armeabi-v7a", "x86"
        }
    }

I ran the Android SDK Manager, and I have the Android SDK Build-Tools Rev 23.0.1 installed, along with all the files for Android 6.0 (API 23).

I searched online for this problem and have tried many solutions; restarting the terminal, deleting the gradle file in the root directory, making sure ANDROID_HOME points to the correct directory (As I am following the ReactNative docs, I have copied in both ~./bashrc and ~./bash_profile the following line: # If you installed the SDK via Homebrew, otherwise ~/Library/Android/sdk export ANDROID_HOME=/usr/local/opt/android-sdk.

Nothing has worked for me so far and I keep getting the same error. I should add that everything was working fine until I installed Android Studio, after which point I started getting this error. I have since then uninstalled Android Studio naively thinking it would solve the problem.

Please help me SO, you're my only hope.

Answer 1

• Find android sdk location.(e.g /Users/username/Library/Android/sdk or /usr/local/opt/android-sdk or /Applications/ADT/sdk)

• Open shell config file that it depends on what shell you're using. ~/.bash_profile or ~/.bashrc or ~/.zshrc.

• Edit or add the following lines to shell config file:

$ export ANDROID_HOME=`YOUR_ANDROID_SDK_PATH` 
$ export PATH=$PATH:$ANDROID_HOME/tools:$ANDROID_HOME/platform-tools

• Restart the terminal and run again.
