Android: I want to use DRM in the market

Question

I want to use Digital Rights Management (DRM) in my application.

Is there a source that uses DrmStore?

Answer 1

DRM in this context is somewhat vague and can mean a couple of things:

Application Licensing

If you are trying to copy the protection of your application, you can use the new Android Market Application Licensing feature.

Media Content Protection

If you are trying to protect multimedia content and cannot use the content protection method inside the application, you may be interested in the new DRM system in Android 3.0 ( android.drm package). The details for using this framework are currently a bit scarce because there are no widely available DRM plugins / agents available to interact with (as of this writing, May 2011). In addition, your implementation may vary depending on which plugin you are using.

More information about this new structure can be found in the Android 3.0 Platform document:

Digital Rights Management (DRM)

New Extensible Digital Rights Management (DRM) System for Verifying and Enforcing Digital Rights. It is implemented in two architectural layers:

• The DRM frame API, which works with applications and runs through the Dalvik virtual machine for standard applications.

• A native code DRM manager that implements the infrastructure API and provides an interface for DRM plugins for rights management and decryption for various DRM schemes.

For application developers, the framework offers an abstract, unified API that simplifies the management of secure content. The API hides the complexity of DRM operations and provides a consistent mode of operation for both protected and insecure content, as well as for various DRM schemes.

For device manufacturers, content owners, and digital media Internet service providers, the DRM framework plugin provides the means to add support for the DRM scheme selected in the Android system to ensure the security of content protection.

The pre-release does not provide any built-in DRM plugins to verify and enforce digital rights. However, device manufacturers can send DRM plugins using their devices.

You can find all DRM APIs in the android.drm package.
