Greetings.
I have a couple of questions.
1.Can I connect Arduino and Android phone using usb cable, thus allowing me to read gas sensor reading on Android Phone?( the plan is to make some sort of docking system, thus allowing Android to act as an LCD monitor)
im just coming up with ways to not use a wifi shield.
It would probably be easiest to communicate between the Android and Arduino using Bluetooth.
If you wan the Android to receive the Bluetooth data and send it with WiFi you will (presumably) need a suitable program on your Android device.

thanks for the prompt reply.
so that means I need to develop an Android app(or find) that pushes the data received from Bluetooth to the Internet, right?

To avoid a Wi-Fi shield I am using an Ethernet shield hardwired to the LAN and posting my data to the internet.
You could also couple the Ethernet shield with a Wi-Fi AP/Repeater plugged into the LAN port, thus giving u Wi-Fi without a Wi-Fi shield.

hmmm can we eliminate the use of Ethernet shield either?
You should be able to go direct to WiFi from your Arduino with an ESP8266 module - much cheaper than a Wifi or Ethernet shield

Cheaper but more power hungry.
Ethernet shield clones can be had for about 5 or 6 bucks.
thanks for the replies.
the scenario is this;
say the wifi router or my internet connection is down or my device is at a place where internet access are not available.
I would like to still get Air Quality readings on my android.
im assuming I can get the readings via Bluetooth module.
once i get the readings on my android, whenever i get back to a place where internet connection is available, i would then send the data to a server

This is certainly possible. As you suggested earlier, it would require an app to save the data and then send it when there's a WiFi connection.
I've used MIT's App Inventor 2 (AI2) to write a couple different Bluetooth apps and AI2 is pretty easy to use but it's also awkward to use if the program is a bit complex.
It's not too hard to add Bluetooth to an app but I haven't tried adding WiFi to an app.
sounds like a cook game of scavenger hunt.
place sensors around campus, low power blue tooth
you have to get close enough to lock in the blue tooth,
then find the sensor.
then pour cold water over to get it to read x degress for 20 seconds.
or breath on it to get humidity to 80 %
or motion sensor on/off 3 times
holymarder, I believe that you posted an XY problem and others fell into it.
you have a sensor,
want to use your android to read the data while you are at a specific location, operator panel or some such.
the android has to be within some close proximity, part of the scope is to not have the sensor use wifi to the net
you want the android to capture the data for later download at a different location.
the question should be :
what technologies can I use with any of the android interfaces ?
I think Android can pick up ir signals.
we know it can do blue tooth
any others ?
what is the data sharing thing when two androids touch ? you can share a photo or video. lots of data transfer.
who knew that the whole StarTrek tri-corder was so close, and widely applied !
I've used 2 apps that do what you are talking about. GetBlue is a freemium app that allows you to log from your phone via bluetooth (what I used), but you may also be able to use USB. It can save it to SD, or log it to a server or Google Drive.
There is a free app at aircasting.org. The software is open source. They have a pollution monitoring platform as well. This app is useful if you want to display map based data.
GetBlue is more flexible and better for stationary readings.
