Copying apps (same phone, different ROMs)

[PHiZ]

I was happily using the ShapeWriter app on stock 2.1. I upgraded to a 2.2 ROM (rooted), wiping data/cache. ShapeWriter is no longer available in the app store. So, I used nandroid to re-load my previous ROM, copied the file com.shapewriter.android.softkeyboard.zip from the old ROM. I then used nandroid to load the 2.2 ROM again.

I am trying to install this .zip file under 2.2. So far I have used ADB to do "adb install com.shapewriter.android.softkeyboard.zip". I get the error "
Failure [INSTALL_PARSE_FAILED_NO_CERTIFICATES]".

What am I doing wrong? Is there an alternative way to accomplish what I want to do? Is it a problem that I have a .ZIP and not a .APK?

(I just tried installing the .ZIP from recover (ClockWorkMod), it did not work.)

Whenever I need to do something along those lines, I just copy the file on to the SD card, then install a File Manager (I prefer Root Explorer personally) and then use that to search for the file and reinstall. You should be able to do this with free file managers like Astro, OI, Linda, Estrong, or AndExplorer as well. It's late though and I am too tired and lazy to double check that for you. lol Hope this helps...

Just thought of it too, check to see if maybe there is just an .apk file inside the .zip you can unpack as well. And, if all else fails, then rename, but I wouldn't think you would have to since you just copied it already and that was the name...

I changed the .ZIP to a .APK extension, navigated to it with Astro File Manager, executed it, it opened in Application Manager, prompted me if I wanted to install (and gave me a list of permissions for the application), but it then failed to install. I did not get an error message through the simple Application Manager interface, but my guess is that it might be the "no certificates" failure from before.
