React Native : target with hash string 'android-X' not found

Question

I am trying to develop my first react-native Android app. When I run

sudo react-native run-android 

I get the following error

JS server already running. Building and installing the app on the device (cd android && ./gradlew installDebug)...  FAILURE: Build failed with an exception.  * What went wrong: A problem occurred configuring project ':app'. > failed to find target with hash string 'android-23' in: /usr/local/Cellar/android-sdk  * Try: Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output.  BUILD FAILED  Total time: 4.981 secs Could not install the app on the device, see the error above. 

I have 24.3.3 under /usr/local/Cellar/android-sdk with all API-23 packages installed

My android/app/build.gradle says

compileSdkVersion 23 buildToolsVersion "23.0.0"  defaultConfig {     applicationId "com.awesomeandroid"     minSdkVersion 16     targetSdkVersion 23     versionCode 1     versionName "1.0"     ndk {         abiFilters "armeabi-v7a", "x86"     } } 

When I try $ANDROID_HOME, it says -bash: /usr/local/Cellar/android-sdk/24.3.3: is a directory.

I have also added local.properties under android/app/ and added sdk.dir=/usr/local/Cellar/android-sdk/24.3.3

Am I missing something?

Answer 1

Your $ANDROID_HOME should point to /usr/local/android-sdk and it would be the parent directory of platforms and platform-tools

Gradle will try to locate tools dir in the following location: $ANDROID_HOME/platform/android-23 so verify that you have your tools installed there if the android-23 folder is not present inside $ANDROID_HOME/platform/ , please install Android 6.0 (API23)
