The configuration method of the ANDROID environment variable _android

When we create AVD, entering the Android list in the Command Line window prompts: ' Android ' is not an internal or external command, as in Figure 1, which is largely due to the lack of configuration of the Android SDK environment variables.

Figure 1 Android is not an internal or external command

There are two ways to solve this problem:

(1) Configure the environment variables of the Android SDK;

(2) Direct access to the Android SDK directory execution (in fact, you can not configure the environment variables directly into the directory execution file).

method One: Configure the Android SDK environment variable with the Android SDK I installed as an example (E:\ANDROID-SDK), as shown in Figure 2.

To set the system environment variable new Android_home (right click My Computer –> attribute –> advanced –> environment variable –> system variable –> new, note "System variable" instead of "User variable of administrator")

(1) android_home=e:\android-sdk (ANDROID SDK directory), as shown in Figure 3;

(2) Add%android_home%\tools in path, and be careful not to change other file paths, just add them after the semicolon, as shown in Figure 4.

If it is version 2.3 and you want to execute the ADB command on any command line, you will also need to add%android_home%\platform-tools to the path, that is,%android_home%\tools and%android_home%\ Platform-tools also joins the path, the tools directory runs the android command, and the Platform-tools directory runs the ADB command, as shown in Figure 4.

Method Two: Directly in the access to the installation directory to execute the file

The android command is under the tools of the Android SDK, Android.bat, related commands, and ddms.bat,traceview.bat.

Figure 6 Direct access to the Android SDK tools execution file

Not all commands are in the tools directory, such as the common ADB command is in the E:\android-sdk\platform-tools directory, and need to enter the directory to execute. For example, the command to view the Android application log needs to go into the E:\android-sdk\platform-tools directory and execute the ADB logcat.

Of course, the above is the 2.3 version of the file directory, different versions of the directory structure may be slightly different, you need to be based on the specific directory to find the appropriate file commands.

The above is on the Android environment variable configuration method, follow-up continue to update the relevant information, thank you for your support of this site!
