Backing Up Apps With allowBackup=false I'm trying to back up the apks and preference data for all of the apps on my device, but it only backs up about a third of them; the remainder all have allowBackup=false in their manifests, which disables the ability to back them up, either with adb or with Helium.

I'd much prefer not to have to go through each of the apks one by one, extract their manifests, change them, then make them apks and add them to my device again. So is there a way of ignoring allowBackup=false when doing adb backup? Or, is there an app or shell command I could run that would find all of the apps with allowBackup set to false and set them to true?

I checked out this app that's supposed to do just that, but was unable to run it since it doesn't have an activity specified. If there's any easy way of getting that to work, or any alternative to it, that would be great.
allowBackup=false
This is specifically put into the application by the developer so that people can not make a copy of the application ( usually to stop reverse engineering ) 

It would probably constitute as copyright if you ignored the allowBackup=false and made a copy of it anyway, so most applications won't allow it to respect other developers wishes. 

This obviously would apply to rooted phones as well.
