Answer 1

Your first code group is a SUCCESS message. The other one is just environment info. Where is the error message?

Unless there is an absolute need to deploy your project using Android Studio, you should use the Cordova CLI to launch your apps .

To launch, you administer the following command from within your project directory:

cordova run android

The command will preferably launch the app from within an attached device. Should you wish to explicitly tell the CLI to launch into an emulator, use the --emulator flag along with your run command:

cordova run android --emulator

Answer 2

解决此问题的一种方法是重新启动模拟器。
