运行代码如下：
public class EengLu {
       
        public static void main(String[] args) throws Exception {
               
                File app=new File("/Users/dsjh/Downloads/meituan.apk");
                DesiredCapabilities caps=new DesiredCapabilities();
                caps.setCapability(MobileCapabilityType.APP, app.getAbsolutePath());
                caps.setCapability(MobileCapabilityType.DEVICE_NAME, "suibianxie");
                caps.setCapability(AndroidMobileCapabilityType.NO_SIGN, true);
                caps.setCapability(AndroidMobileCapabilityType.UNICODE_KEYBOARD, true);
                caps.setCapability(AndroidMobileCapabilityType.RESET_KEYBOARD, true);
               
                AndroidDriver<AndroidElement> driver=new AndroidDriver<>(new URL("http://127.0.0.1:4723/wd/hub"),caps);
               
        }
