Installing Android SDK Problem (SOLVED)

I few months before installed Android Sdk (adt bundle).There was a option named Android Api Lvel 20 system image revision 1 and I selected that and then clicked on install package option and paused the download then I had manually downloaded a Android System Wear Image of (Api Level 20, revision 1) (Size 100 mb nearly) and installed it by replacing it in the android temp folder(sdk/temp) and it worked nicely…But now again I want to install Android Sdk but now the option System Image wear v20 revision 1 has gone and it is showing revison 4 instead of revision 1 so if I now select the revision 4 and click on install package option and then pause it and replace the temp folder with the image of revision 1 I downloaded earlier, it is no more working…
So my question is how can I get the revision 1 option back in my Sdk…

Why are you pausing an installation and then installing something in that location while it’s paused? That sounds like a recipe for disaster.

90% of problems like these can be solved by simply uninstalling and reinstalling everything. Maybe try that?

I’m not really sure why you are trying to install that manually.
The way you are doing so (as KevinWorkman pointed out) is a very bad idea anyways.

Assuming you are using the Android SDK Manager for all this installing stuff, you can just select what you want installed or not installed. (No need for manual installing)

Also why do you want rev. 1 instead of rev. 4?
With rev. 4 you are still getting the Android Wear System Image you want, just an updated revision of it.

First of all I need manual installing because the size of the image is 108mb and so I need to redownload the huge file again and again I format my PC.

I want rev. 1 because I already have the image of rev.1 so I dont want to download again rev. 4 of size 112 mb (data cost is very high in our country)…I want to reuse my previous downloaded image…Pls help…

Ok atlast I got the solution…I had to do some reverse engineering with the XML file for Sys-img s which was sent by Google server …and atlast it isworking…by the way thanks to the above members who have replied…
