*****This will work on other Jelly Bean devices it is the same concept*****
Ok so everything about the ASUS Nexus 7 tablet is phenomenal in my opinion. I love the fact that like they say, “it is a pure Google experience.” No bloatware no manufacturer customization is apparent on the Nexus 7. It is a very powerful 7 inch tablet and it runs really smooth. The only complain that I personally had at first was the fact that I was not able to play Amazon Instant Videos(for Amazon Prime members) on it because Adobe will no longer be supporting the Android operating system in particular the newest release of the Android operating system, Jelly Bean. Could I have gotten the new Kindle Fire HD and not have to worry about this? Yes, of course but while I was at Best Buy trying to get a Nexus 7 I was playing with the Kindle Fire HD they had on display and I personally wasn’t too impressed with it. Will I get it in the future? I most likely will get it later on in the future but only because I just absolutely LOVE technology. Eventually getting the Nexus 7 and after doing some research I found a way to enable the streaming of Amazon Instant Videos on your Nexus 7 and this post is me sharing it with everyone so that you don’t have to go through what I went through. 
Step 1:
Go down to the end of this post and download the Adobe Flash Player apk. It is the actual application. You can’t download the application from the Google Play Store anymore because Adobe is not supporting JellyBean.
Step 2:
On your Nexus 7 make sure you go to settings and then go to usb debugging and make sure that the box is checked. Do the same thing for Allow mock locations.
Step 3:
Go back and then go and click on where it says, “security.” From the home screen of your Nexus 7 you can go back into settings and then click on where it says security. Once you have clicked on where it says security towards the bottom you will see something that says, “unknown sources” make sure you click on the box for that. Checking unknown sources allows you to install apps from platforms other than the Google Play store. After you click on unknown sources the box should be checked.
Step 4:
The Adobe Flash Player apk that you downloaded in step one should be on your computer by now. If it is not go ahead and download the apk and put it on your desktop so that it is easy to find. Once the apk is on your desktop connect the Nexus 7 to your computer via the micro usb cable. As soon as you connect the Nexus 7 to the computer the usb drivers should automatically start downloading and installing onto your computer. If not you can always just do a google search for the usb drivers and download them manually. Ok, so copy the apk from your desktop on to the download folder of your Nexus 7 tablet. Once the apk has been copied onto your Nexus 7 use a file manager app from the Google Play store and go into the folder that the apk is located in. For instance if you copied the apk onto the download folder of your Nexus 7 go into that folder and then install the apk.
Step 5:
Go to the Google Play Store again and download the xscope browser from the Google Play Store. It is $2.99 in the Google Play Store but if you want you can get the application for free from xda-developers.com.
Step 6:
Log onto your Amazon Prime account by clicking on the xscope browser.
Once, you are logged into your Amazon Prime account through the xscope browser you can just go ahead and play a video and stream it onto your Nexus 7 without any problem. Congratulations since you are now able to stream Amazon Instant Videos onto your Nexus 7. If you have any questions don’t hesitate to ask by leaving a comment here on my website or preferably on my YouTube channel.

Download the Adobe apk:
Thank you! I was on the verge of buying an iPad, I was so unhappy about not being able to watch Amazon Prime Instant Video on the Nexus 7. You made my day! (And saved me a whole bunch of money!)
You are very welcome and I am glad I was able to help out.
Yeah, I was unhappy about not being able to watch Amazon Prime but then I figured that there was a way around it. 
That link is to dolphin browser not adobe.
Follow the above link “Adobe Flash Player. apk” Then once at the Dev-host website, click on the “search” box and type in “adobe flash player” look for the one by techfanatic9…it has about 19,000+ downloads and like 20 comments. Description says “use this to get flash on jelly bean devices.” Download this version of flash (11.1). Go on your Nexus 7 downloads and find the .apk adobe file and install the software. Then install the xscope browser from the Google play store ($2.99). I did all the above above and am watching Terminator via amazon prime!
