You can choose when, and how often, you want your application to check its license and you have full control over how it handles the response, verifies the signed response data, and enforces access controls. From http://developer.android.com/guide/market/licensing/overview.html So yes basically whenever the developer wants it to. I'd imagine the most ...


According to their dev blog, the appstore does download a small token for DRM'd apps which it uses to validate them at launch: How can you verify that the user has an entitlement to the app without internet access? During the installation process for an app, the Amazon Appstore client downloads a small token that grants the user the right to ...


Paid Apps are tied to an Google account. But this is because of the Google Framework and not because of Android. No one needs to "remove DRM from Android" because there is no DRM within Android. Only support for it. If you install free (as in beer) Apps, everyone can use them. There is only one imitative that goes one step further then being DRM-less: ...


Some are DRM protected, others aren't. One way I'm aware of to find out the ones that are DRM, is when you try to download the file for offline reading: If the extension is .acsm then its a DRM protected book. If the extension ends in .epub or .pdf then its not DRM. protected. Related reading: File types for reading on your device DRM options for ...


Strictly speaking, you don't have to use Google's services if you don't want to. Newer Android OS versions (2.3 and above, if I'm not mistaken) allow you to bypass the initial sign-in with a Gmail/Google account. You lose the synchronization with Google's services, but otherwise the phone will be functional. You can then use other services (e.g. Amazon, ...


The answer is "android.clients.google.com" with port 5228 (TCP).


This has basically been answered in the comments above but I'll wrap it all up into an answer: No, you can't play songs that have Apple's Fairplay DRM protection on your Android phone without removing the DRM protection (which technically violates Apple's toc). As Edarerathis pointed out, Songbird doesn't actually support Fairplay DRM'd media, Quicktime ...


There are two types of protection offered by the Android Market. The original copy protection is now deprecated and is apparently fairly easily circumvented. Google now recommends that developers implement its licensing service, which requires a bit of effort on the part of the developer. It requires Internet connectivity and checks whether the Google ...


I just learned this lesson the hard way. Amazon requires at least a once daily connection to the internet or you won't be able to access your apps purchased from them. I was overseas with spotty internet service and after one day all apps gave me the same error message. Amazon made no apologies when I complained, but they refunded my purchases so I could ...


DRM stands for "Digital Rights Management", and mainly is used with sold eBooks/PDFs and the like (and also for sold music files plus maybe even videos). Those keys are to identify your ID as to prove if you have permission to access those documents. If you never bought any of those "crippled" documents, chances are you don't have to bother.


There does not appear to be a way, no. (Some information in this forum thread: http://www.droidforums.net/forum/droid-audio-video/40610-zune-not-droid-friendly.html) Apparently, DRM'd wma files require a Zune device. Since Droid ≠ Zune, it's not going to work. Unless and until Microsoft decides they want to build a Zune App (à la the way Amazon has a Kindle ...


Usually no - however, it's my opinion that this is a rather vague question that can't be accurately answered without knowing the app developer's policy or whether the app is locked to a particular region.


There is an alternative to the AOSP/CM which frees you of any closed source versions of Android along with @Chahk's answer called Replicant. And it incorporates F-Droid into it as in, free open source software without DRM. It would be quite easy to port to a device that has a known working CyanogenMod device tree for the said device in question.


I use Mantano Reader for this purpose, it's quite a powerful app. Give it a try and you'll like it!
