(Mac OS/Linux) How to Set or Change an Environment Variable Variables in Unixes are case-sensitive. Global environment variables (available to ALL processes) are named in uppercase, with words joined with underscore ( _ ), e.g., JAVA_HOME. Where to Set Environment Variables in Mac OS X. This is definitely helpful. One important thing is where the JAVA HOME environment variables are kept, which is in the screen shot shown here. For Java and JRE users this is often essential to modify dependin.
. Meet Android Studio. Manage your project. Add C and C code. Write your app. Build and run your app.
Run apps on the emulator. Run apps on a hardware device.
Configure your build. Debug your app.
Test your app. monkeyrunner reference.
Profile your app. Inspect CPU activity. Publish your app. Command line tools. You can set environment variables for Android Studio and the command-line tools that specify things like where the SDK is installed and where user-specific data is stored. This page describes the most commonly used environment variables. The following example shows how to use an environment variable to launch an emulator when the SDK installation has been put in E: Android sdk instead of in its default location of $USERHOME or $HOME.
$ set ANDROIDSDKROOT=E: Android sdk $ emulator -avd PixelAPI25 Variables reference The following table describes commonly used environment variables for the Android SDK tools. Environment variables Android SDK environment variables ANDROIDSDKROOT Sets the path to the SDK installation directory. Once set, the value does not typically change, and can be shared by multiple users on the same machine. ANDROIDHOME, which also points to the SDK installation directory, is deprecated. If you continue to use it, the following rules apply:. If ANDROIDHOME is defined and contains a valid SDK installation, its value is used instead of the value in ANDROIDSDKROOT.
If ANDROIDHOME is not defined, the value in ANDROIDSDKROOT is used. If ANDROIDHOME is defined but does not exist or does not contain a valid SDK installation, the value in ANDROIDSDKROOT is used instead. REPOOSOVERRIDE Set this variable to windows, macosx, or linux when you use to download packages for an operating system different from the current machine. Note: You can use Android Studio instead of sdkmanager to manage your SDK packages. Android Studio configuration environment variables The Android Studio configuration variables contain settings that customize the location of configuration files and the JDK. On start-up, Android Studio checks these variables for settings.
For more information, see. STUDIOVMOPTIONS Sets the location of the studio.vmoptions file.
This file contains settings that affect the performance characteristics of the Java HotSpot Virtual Machine. This file can also be accessed from within Android Studio. STUDIOPROPERTIES Sets the location of the idea.properties file. This file allows you to customize Android Studio IDE properties, such as the path to user installed plugins, and the maximum file size supported by the IDE. STUDIOJDK Sets the location of the JDK with which to run Studio. When you launch Android Studio, it checks the STUDIOJDK, JDKHOME, and JAVAHOME environment variables in that order. Emulator Environment Variables By default, the emulator stores configuration files under $HOME/.android/ and AVD data under $HOME/.android/avd/.
You can override the defaults by setting the following environment variables. The emulator -avd command searches the avd directory in the order of the values in $ANDROIDAVDHOME, $ANDROIDSDKHOME/.android/avd/, and $HOME/.android/avd/.
For emulator environment variable help, type emulator -help-environment at the command line. For information about emulator command-line options, see. ANDROIDEMULATORHOME Sets the path to the user-specific emulator configuration directory. The default location is $ANDROIDSDKHOME/.android/. ANDROIDAVDHOME Sets the path to the directory that contains all AVD-specific files, which mostly consist of very large disk images. The default location is $ANDROIDEMULATORHOME/avd/.
You might want to specify a new location if the default location is low on disk space. The Android emulator queries the following environment variables when it starts.
ANDROIDLOGTAGS See. HTTPPROXY Contains the HTTP/HTTPS proxy (host name and port) setting for a global http proxy. Uses a colon (:) separator between the host and the port. For example, set HTTPPROXY=myserver:1981.
ANDROIDVERBOSE See. ANDROIDEMULATORHOME See.
ANDROIDSDKROOT See. ANDROIDEMULATORUSESYSTEMLIBS Contains a value of 0 (default) or 1. A value of 1 means to use the system's libstdc.so file instead of the one that comes bundled with the emulator. Set this enivronment variable only when the emulator does not start on your linux system because of a system library problem. For example, some Linux Radeon GL driver libraries require a more recent libstdc.so file.
Note: There is no guarantee that setting this environment variable to 1 will make the emulator runnable. It is a work-around for system library issues that affect a very small number of Linux users.
