Environment variables for Android development
ANDROID_HOME Deprecated (in Android Studio), use ANDROID_SDK_ROOT instead. ANDROID_SDK_ROOT Installation directory of Android SDK package. Example: C:\AndroidSDK or ~/android-sdk/ ANDROID_NDK_ROOT Installation directory of Android NDK package. (WITHOUT ANY SPACE) Example: C:\AndroidNDK or ~/android-ndk/ ANDROID_SDK_HOME Location of SDK related data/user files. Example: C:\Users\<USERNAME>\.android\ or ~/.android/ ANDROID_EMULATOR_HOME Location of emulator-specific data files. Example: C:\Users\<USERNAME>\.android\ or ~/.android/ ANDROID_AVD_HOME Location of AVD-specific data files. Example: C:\Users\<USERNAME>\.android\avd\ or ~/.android/avd/ JDK_HOME and JAVA_HOME Installation directory of JDK (aka Java SDK) package. Note: This is used to run Android Studio(and other Java-based applications). Actually when you run Android Studio, it checks for JDK_HOME then JAVA_HOME environment variables to use.
