[Nexus 7 General] superflysocal:
In case you don't know and if storage is an issue for you, you can use USB storage devices like flash drive, SD card reader, etc. by using an microUSB OTG cable, root your phone, and install Stickmount as per this thread:

However, I was also looking into alternative methods to increase indirectly increase storage capacity like things like videos and media. Media including videos and music, I believe is the number one reason why people want to increase their storage, so we will concentrate on that. My example scenario will be wanting to watch a movie on a plane (in which there is no wifi internet available).

There are wifi hard drives like Kingston wi-drive and Seagate GoFlex Satellite wifi drives that would work (haven't tested myself), but those arent' cheap. CloudFTP is similar but is still expensive. I would like to see a similar device without any onboard memory, but at a cheaper price, basically something like CloudFTP but at around $50-60. If anybody knows of one, that would be great!!

Then I thought about why not use the hardware you already have and carry with you at all times, your phone? It has wifi and it has expandable memory (most do at least). It would be great if an app can allow you create a wifi network (ad hoc network?) that Nexus 7 connect to and can then share the storage on your phone.

Well, I couldn't find one that does all of that in one step, but I did manage to get it to work with a few steps based on this reply by mrfahrenheit94 (THANKS!):

Basically:

1. Wifi tether your Nexus 7 to your phone (ie Wireless Tether for rooted phone).

2. Run Es File Explorer on your phone (latest version I am using version 1.6.1.6 from Play market, just make sure it supports remote FTP server). Go to Settings, then Remote Settings (Under Network Settings). Check Remote Manage. It will display an ftp address.

2. Run ES File Explorer on Nexus 7. On the upper left hand corner, press the button that probably says Local by default and has a small down arrow. Select FTP. Now press "New" and then select FTP again to add FTP server, Under Server, enter the FTP address that was displayed at the end on step 2 on your phone (do not enter the "ftp://" part, just the numbers after it), but only enter the adress before the colon. Under port enter the number after the colon. Then check the anonymous box. Press OK and now you should have that FTP address as an icon. Select it and you should now see your phone's files and folders. Now you should be able to navigate to your video or media files and select it to play using an external media player. I suggest using Dice Player (free with Ad version). VLC Beta may work as well but I seem to have more luck with Dice Player.

Main drawback will be battery life especially on the phone!!!!

Thus I tried to do this with bluetooth by using Foxfi to tether. At home it worked and I was able to stream a video although very slight stutter at times. However, i realize that Foxfi only worked when my phone has an internet connection (which is not true when on an airplane).

THUS, IF YOU ARE GOING TO TEST THIS, TURN OFF YOUR CELLULAR DATA CONNECTION TO TEST IF IT WILL WORK WHEN YOU HAVE NO INTERNET LIKE ON A PLANE.

It does for the Wireless Tether app on Play market even without internet.

What I would like to know and for us to discuss:

1. Any other alternative methods for using wifi storage?

2. Any app that is similar to Foxfi that can Bluetooth tether but doesn't require an internet connection?

3. Any app that can just create a network connection between the two android devices without actual tether feature?

4. A IOS app similar to ES File Explorer to navigate ftp server. Maybe set it up in XBMC?

5. Any interest in a developer creating a one step app that connects and share two devices via wifi and/or bluetooth without any tethering (and thus would work for nonrooted phones)?

One thing I envisioned was one a plane I bring nexus 7 for the kids and my asus TF300 for myself. I would love it if I can share the videos from the TF300 which has a larger capapcity and bigger battery than my phone to the Nexus 7, but I couldn't get Wireless Tether to work on the Asus Tf300 (probably because it is not a phone). Hence, the request for #3 above.

I apologize if this is common knowledge and a waste of time for many of you.
