2. Problems encountered in installation

①Unable to access Android SDK add-on list

【reason】

　　A. After installing AS for the first time and starting it, it is detected that the computer has no SDK. This can happen even if the Android SDK is ticked.

　　B. You can install the sdk later, or set the AS to be opened for the first time without downloading the sdk.

4. Problems in operation

①Error：Connection timed out:connect.If you are hahind an Http proxy.Please configure the proxy settings ether in IDE or Gradle.

【reason】

 Because the project configuration (gradle, build) is different from the local one, it must be updated. But at the same time, we can't access Google's related websites, so we can't make updates.

【Solution】

　　A. Modify gradle to the locally downloaded gradle, and set it to your installed version such as 2.2.2. (build.gradle2gradle->wrapper->gradle-wrapper.properties)

　　B. Modify the classpath in build.gradle to specify the gradle version to support the gradle version number specified by gradle in the above example: gradle-2.2.2 

       C. Synchronize after modification
