How to Find a Wireless LAN Access Point

→Under Android Wi-Fi Tutorial,
mainWifiObj.getScanResults is searching for hotspots.However, it is important to note that in this case, hiddenSSID cannot be searched.

...When I implemented it as a support app for development in-house, Huawei's device notified me of the intents for a long time, so I gave up listening to communication by trying to mechanically retry the connection about 5 times in the middle.

I hope this will be helpful.
