Python+appium自动化踩坑（二）：Original error: The instrumentation process cannot be initialized. Make sure the application under test does not crash and investigate the logcat output.

在使用appium启动手机应用时，报错：

An unknown server-side error occurred while processing the command. Original error: The instrumentation process cannot be initialized. Make sure the application under test does not crash and investigate the logcat output.

现象：如图在Start Session 后，需要在手机上安装，Appium Setting 、io.appium.uiautomator2.server 、io.appium.uiautomator2.server.test，一切软件都装完成后，Appium报错：An unknown server-side error occurred while processing the command. Original error: The instrumentation process cannot be initialized. Make sure the application under test does not crash and investigate the logcat output.

 如果终止某个软件安装，报错：An unknown server-side error occurred while processing the command. Original error: Error executing adbExec. Original error: 'Command 'D:\Android\Sdk\platform-tools\adb.exe -P 5037 -s D3H0217C13000820 shell pm install -r /data/local/tmp/appium_cache/0cc1725a60a05dbb5d0d09256f2fc6ece7e3b10f.apk' exited with code 1'; Stderr: ''; Code: '1'

 

 最后在全部日志中查找出，If you wish to use that automation instead of UiAutomator2, please add 'automationName=UiAutomator1' to your desired capabilities。

 

 

 所以，在添加参数的时候加上参数 automationName=UiAutomator1。结果成功解决问题。
