Hi All -

Firstly.. Please don't burn me for being thick!..

I've been trying to see how much I can get out of my phone since I got it, without having to root and mess about "under the hood" of the apps I've installed..

But now I'm getting curious and for my first attempt at this I will remain "unrooted"..

I've got ADW and I want to amend some of the .png files - so I tried extracing the app from the phone, openned the APK using winzip and amended some of the .png files.. I've uninstalled ADW from the phone and then tried to reinstall the updated version which I've put back onto my SD card - but it says "Cannot install ADW on this phone".....

I've had a search around XDA but can't find anything that helps..

If there is already a thread that talks me through this please point me in the right direction, otherwise if someone could explain to me if I'm missing a step I'd appreciate it!..

Cheers!

Alan.


EDIT - Ok - It's solved... I downloaded the SignApk app off t'internet signed the new APK that I'd created and then sent it back to my phone - which worked.. finally solved.

Thanks for all who helped me..

Solution is - YOU HAVE TO SIGN the Apk if it's NOT a system APK..

if i read correct you have extracted the apk ? If yes it won't install unless you sign it. All you have to know about signing is here .

Or you can just open the archive with 7zip or whatever you want and drag the files there and it will work just fine.(Haven't checked though but it was pointed out here ) .

Hi - Thanks for this...

By Extracted... What I did was I used astro to back it up to the SD card then bluetoothed it to my laptop - opened the APK using Winzip and edited some of the png's within the archive.. then I saved it, bluetoothed it back to my SD card and tried to reinstall it from there..

that's I got the message "can't install ADW on this phone" message...

?? Perhaps I need to extract it differently? or would I need to re-sign it first?

Thanks again.

Use 7zip instead and right click the apk and hit open archive instead of extract. Then drop the files u edited into the correct folder. It should install...

Hope it helps. :)

Drag n drop works for system apps but for apps like the ones in market ul need to remove meta inf folder, sign the apk file n all should be well. although I think because the certificates have been changed you won't be able to update it via market. I've done quite a bit of editing..
