在使用appium啟動手機應用時，報錯：
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.
現象：如圖在Start Session 后，需要在手機上安裝，Appium Setting 、io.appium.uiautomator2.server 、io.appium.uiautomator2.server.test，一切軟件都裝完成后，Appium報錯：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.
如果終止某個軟件安裝，報錯：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，在添加參數的時候加上參數 automationName=UiAutomator1。結果成功解決問題。
