  1. try to use android_tutorial_map_viewer first
  2. check the ROS_IP is set correctly on your host machine (this is very important. eg. ROS_IP="192.168.1.104". check the ip using "ifconfig" on your host machine, and also make sure your android phone and your host machine are in the same wifi.)
  3. on your android phone side, try to use two fingers to scale/rotate while running map_viewer app, the map should appear on the screen

I have the same situation. If I use my phone's Personal Hotspot as a wifi, it works , the map shows, everything seems normal. But if I use tp-link wifi, the app shows it has connected, and on the ros side, "rosnode list" shows android node, however, the app still doesn't show map. Could anyone give me a hand?
