Looks like there’s some support in Android SDK for OMA DRM.
android.drm.mobile1.DrmConstraintInfo android.drm.mobile1.DrmException android.drm.mobile1.DrmRawContent android.drm.mobile1.DrmRights android.drm.mobile1.DrmRightsManager
There’s a matching shared object as well named libdrm1_jni.so as well in /system/lib. I cannot find any information on the android site though other than the tantalizing clue here – Environment.getDrmContentDirectory()

Here’s a partial listing of the available services on android.
android.os.IServiceManager sm = android.os.ServiceManagerNative.getDefault();
try {
String[] services = sm.listServices();
for (int i = 0; i < services.length; i++) {
Log.i("Services", i + " : " + services[i]);
}
} catch (DeadObjectException e) {
Log.i("Services", e.getMessage(), e);
}
Now we try to dig thru the API to figure out which ones are available to applications. Here’s what i have found so far.
android.os.IUsb usbService = android.os.IUsb.Stub.asInterface(sm.getService("USB"));
javadoc – IUsb
android.app.IActivityManager activityService = android.app.IActivityManager.Stub.asInterface(sm.getService("activity"));

android.os.IVibratorService vibratorService = android.os.IVibratorService.Stub.asInterface(ServiceManager.getService("vibrator"));
android.view.IRingerVolume volumeService = android.view.RingerVolumeNative.asInterface(sm.getService("volume"));
android.view.IWindowManager windowService = android.view.IWindowManager.Stub.asInterface(sm.getService("window"));

You can find busybox on Benno’s site. If you can find the location of the .db file, you don’t really need busybox. Though i highly recommend it since it has many useful utilities.
