[Android self-study Note] the solution "remote host forced closing an existing connection" appears during Android real machine test.

Recently, during a real machine test, "the remote host forces an existing connection to be closed ." Then I started the connection. After searching for a long time on the Internet, no one said clearly. I met myself and shared the solution to everyone:

The reason for this is that ADB is not connected. Open the ddms to view devices column, and there is no real machine in it.

2. The second type is relatively simple, because ddms integrates the components required for Android Development

Note the drop-down menu in the red box.

After opening, select the last one: reset ADB and then click OK.
