Remember that when developing applications on Palm OS in the early days, if you need to debug on a real machine, you have to connect to the computer through a dedicated base. With the popularity of USB, various dedicated cables and interfaces began to decline, and devices seemed to switch to USB overnight. Now wireless is the king, and simple is the best. Android devices use USB and PC for communication debugging by default (some newer devices use TC

Qt do Android development, sometimes need network information, this example is to get a phone search to the signal strong WIFI signal list. The knowledge of JNI is needed in the process.
