Downgrading System Apps - Android Q&A, Help & Troubleshooting

Hi,
I'm wondering if it's possible to downgrade a system app to an earlier version than the one that came with the phone/rom. I prefer the older version of Chrome with merged tabs and apps but the earliest version I can get (by uninstalling updates) on my current rom is from after that feature was removed. I tried replacing chrome.apk but it didn't seem to work.
Any help would be appreciated. Thanks.

[Q] Need to install Apps as Non-market apps

I could install the apps to my HTC HD2 Android with CM7 before. After I flash my device to the AmeriCanAndroid AOSP HD2 GB2.3.7 CM7.2, I tried to reinstall the apps from my Market Place profile but it reported my device was not compatible to that apps. I directly download the apps and need to install the apps as non-Market apps? The apps work fine.
My question is why the apps report incompatible with my device? Not only one apps has this problem, what should I do to solve this?
Best regards,
Kelvin.
App Compatibility
Which apps have you tried re-installing?
Perhaps they aren't yet compatible with something updated in GB 2.3.7?
When they were running, what OS version was on your device?
For example the Adobe Reader. PasswordWallet, SyncMate (as I can't post the URL in the reply, apps is easily to search it out from Google)
One of the most popular instant messager in China, the QQ also reports Parse error (There is a problem parsing the package) and cannot be installed.
They claimed this firmware 2.3.7 which was optimized by non-official source.
Any suggestion that I can do the installation?
Best regards,
Kelvin.

(Q) To rom devs

Hi..
Dont want to bash on anyone or come out as whining.
4 out of 5 new roms released or updated states that apps are updated to newest versions. Looking
at Google Play Store, all of them are still with 3.5...which is really a outdated version. Newest version
is 3.9.16.
So my question is, why dont you include the newest version, which also have the future of deleting apps
from your installed list ?

Click to expand...
Click to collapse
You can install it manually if you want to. Just download the latest and go to system/apps to delete Vending.apk
and rename the file you've downloaded to Vending.apk and reboot

2. Latest one
I am using my own build made from the AOSP code on these devices - android market is disabled in the build.
Also what is the procedure/licencing for packaging the Gmail.apk as part of your own build from the Android AOSP code ?

[Q] Blocking standard system OTA updates on my own ROM

Hey guys,
I've created my own ROM by modifying a 5.0 stock one (deodexing, resigning and adding system apps). But the Android 5.1 OTA update keeps showing up (of course i can't update, because of the different signature).
So my question is: Is there a way to modify some config or delete something from the ROM files, for the system not to check for system updates?
Maybe the name of the ROM or something like that?
Any help is appreciated,
Thanks,
Vlad Ostrovski
