Install Android SDK v23 should resolve your problem.

enter image description here

Update answer:

Android API 23 I installed but when I install Android SDK Build-tool 23.0.1 it's working while Android SDK Build-tool 23.0.2 or 23.0.3 not working

Because 23.0.1 is the default SDK version for a React Native project. I don't know how to modify this but if you want to see the build version, checkout this file android/app/build.gradle. You would see a section with following content:

android {
    compileSdkVersion 23
    buildToolsVersion "23.0.1"
}

You need to install the Android build tools via Android Studio.

  1. Open Android Studio
  2. Go to Tools > Android > SDK Manager
  3. Click "Launch Standalone SDK Manager" at the bottom of the window
  4. Find the referenced package and check it (see below)
  5. Click "Install packages..."
  6. Agree to the licences

Android SDK Manager

You should then be able to build onto the device.
