Recently used PC and the mobile terminal through the USB connection to transfer data, thus always using Adb command codes for fault tolerance and strict logic, like the data prior to transmission, PC and mobile terminal to establish a session, to prevent the movable terminal not connected directly transfer data being given, to find such methods for a long time did not find, then himself Adb implement this method in the code inside through. For your reference, we welcome a better way to achieve more exchanges.
Directly on the code
/**
* @Description： 判断是否连接设备
* @Param： []
* @return： boolean

*/
public static boolean isLinkDevices(){
String str = this.adbCmd("D:\adb\adb devices");
assert str != null;
str = str.replaceAll("List of devices attached", "").replaceAll("\n", "");
if (!str.isEmpty()){
System.out.println("已连接设备，设备名为："+str);
return true;
}
System.out.println("未连接设备");
return false;
}
/**

public static String adbCmd(String cmd){
Process process;
try {
process=Runtime.getRuntime().exec(cmd);
System.out.println(inputStream2String(process.getInputStream()));
return inputStream2String(process.getInputStream());
} catch (IOException e) {
e.printStackTrace();
}
return null;
}
/**

private static String inputStream2String(InputStream inputStream){
String result="";
BufferedReader br=new BufferedReader(new InputStreamReader(inputStream));
try {
String temp="";
while ((temp=br.readLine())!=null){
result+=temp+"\n";
}
} catch (IOException e) {
e.printStackTrace();
}
return result;
}
Use this code needs to have adb driver download locally, I was directly on the D drive
