Hi, SPrime and gp123

Thanks for your very helpful advice.

Now I know how to uninstall applications from my N7.

I just want to know do these uninstall methods delete all the uninstalled application files including data files and temporary cache? In the Windows world, there are some "Clean Uninstaller" applications to help you remove all unneeded files from your PCs hard drive when you uninstall a program. I want to know do I have to find one clean uninstaller app for my N7.

Thanks.

Hello, S.Prime.

I tried to install the "cool reader" in my N7.
When I select the .mobi file from my Google Drive (or even I set that file as an offline use file),
there comes a message window (and closes very fast that makes me can not read the message well)
to show the system is downloading it, but nothing happens after the message window disappears.
I tried to use "cool reader" with both my N7 and ASUS TF300 and it does the same thing on both of them, can not open the file.

I tried to use "Mobipoket Reader" on my PC to read the same file, it works well.

Ok, let me to do more research to find the way to open it.

Thanks.

Hi. I'm a new user of Nexus 7 and I love it.

I'm trying to use it to read some ebooks which I saved in Google's g-drive.
I downloaded and installed the Sony Reader in my Nexus 7 from Google Play.
But when I try to open the ebooks with the .mobi and .epub formats,
there comes an error  message on my Nexus 7 that says:
"Unable to open document. No viewer is available for this type of document."

I know Sony Reader can open those files because I'm using it on my ASUS TF300 tablet too, and it works well.
Does anyone know what's wrong with my Nexus 7? Any advice is helpful.

Thanks.
