Appium automation test foundation - mobile end test environment construction (II)

（ 3、 ... and ）Android_SDK install

Android SDK refer to Android Exclusive software development kit .
Android SDK Is a free professional programming language , Allows you to create Android Applications . from Google For which Android platform-developed Android SDK Is a convenient program for mobile application developers , It contains Android The programming language begins to build all the content needed for the application , And a complete functional device simulator , So that you can test when you finish the test .
Android SDK It provides mobile software developers with the opportunity to play on the new platform . It contains everything you need to start building applications in this programming language , And a complete functional device simulator , So that you can test when you finish the test .
1、Android-sdk download
Download address ：http://www.androiddevtools.cn/
Go to the download page and click Android SDK Tools  --> SDK Tools  It will jump to Android-sdk Download location , And then according to our own system , Just download it on demand .

2、Android-sdk Use
（1） decompression Android SDK Compressed package
decompression android-sdk_r24.4.1-windows.zip, When the unzipped Directory , Put it in your own designated position .
Remember the location of this directory , And there should be no Chinese in the catalog .

Android SDK The directory structure of is as follows ：

The description of the directory structure can be viewed csdn Bloggers are ： Software testing automation test article （ in the future ）
（2）Android API download
Android SDK After decompressing , We need to download Android API.API Are some predefined functions , By calling these functions , It enables the program to use the hardware or software of the device itself .
open Android-sdk-windows Folder , double-click SDK manager.exe file , We need to install Tools、Platform-tools、Build-tools、API Etc . In the installation API when , According to the simulator or real machine to be tested Android On the version , For example, the real machine used is Android7.1.1 edition , be Android SDK To download Android7.1.1 Version of API Can only be .

Need basis Android7.1.1 Corresponding API Level downloads correspond to Android SDK Build-tools edition .

Finally, we click on... In the lower right corner Install 1 package... perhaps Delete packages... Install or uninstall related components .
We click Install 1 package... Install the selected components .

Check Accept License And then click Install Installation .

A version of Android API Probably need 20 individual G Left and right space , It takes patience .
explain ：

• SDK Manager It's just one. Android Software development kit Manager , It's like a bridge , Connect local and server , Download Android development tools from the server to the local .
• SDK Platform The next latest one will do , It can be downward compatible .
• Android Support Respository Android compatibility Library , Must install .
  Below SDK Manager Illustration , That's a good summary .

（3） Configure domestic image download Android API
Because the download of foreign resources is sometimes slow , At this time, domestic image resources can be configured .
In the pop-up Android SDk Manager⻚⾯, Click on Tools , Drop down the box and click Options...

The image address list can be used by itself ⽹ Find the latest on .
3、 To configure Android-sdk environment variable
Type at a command prompt adb The order will appear adb Not an internal or external command .

There are two solutions ：
（1） To configure Android sdk Environment variables of .
（2） Go straight into Android sdk In the directory platform-tools Execute the command in the directory .
To configure Android-sdk environment variable , First, make sure AndroidSDK The related components have been downloaded . And then the same Java The configuration of the environment variables for is roughly the same .

• （1） Enter the system environment variable configuration interface .
  My computer --> Right click --> attribute , Then select advanced system settings --> environment variable .
• （2） Create a new... In the system variable ANDROID_HOME environment variable .

 

（3） take Android SDK in platform-tools and tools Directory path for , Add to system environment variable Path in .

（4） verification Android-sdk Whether the environment variable is configured successfully
Restart a command prompt , Input adb command , It is shown that Android-sdk Environment variable configuration succeeded .

4、SDK manager.exe Solution to the problem of flash back

（1） Question why :
SDK Manager.exe By calling android-sdk-windows\tools\lib\find_java.bat confirm java.exe The path of . Enable cmd.exe The command line switches the path to android-sdk-windows\tools\lib, perform find_java.bat Tools , See the output ：C:\Windows\system32\java.exe.
Although the path exists java.exe, But it's not JRE Installation path for . It is estimated that it is due to some needs Java When you install your software , take  java.exe、javaw.exe、javaws.exe  Copied to  C:\windows\system32  Next , Lead to  SDK Manager.exe Called... In the wrong location  java.exe  Caused by .
（2） resolvent :

• Method 1： Delete  C:\Windows\system32\ Under the  java.exe、javaw.exe、javaws.exe  Can solve .
• Method 2：
  Edit open android-sdk-windows\tools Under the Android.bat file .
  find 35 OK, let's start

rem Check we have a valid Java.exe in the path.
set java_exe=
call lib\find_java.bat
if not defined java_exe goto :EOF

modify set java_exe= To your local Java In the installation directory java.exe Tools
take  call lib\find_java.bat This line , Change to  rem call lib\find_java.bat.

rem Check we have a valid Java.exe in the path.
set java_exe=F:\DevInstall\envs\java\jdk1.8.0_144\jdk\bin\java.exe 
rem call lib\find_java.bat
if not defined java_exe goto :EOF

Keep close Android.bat file , Reopen Android SDK Manager that will do .
