Downloading DRM content in Android

 

Android has support for OMA DRM 1.0 (forward lock); however, DRM APIs are not available as part of the Android SDK. Therefore, one way to download DRM content on the handset programmatically is via browser application. The application can ask the browser (via Intent) to download the DRM content, as shown:

 

 

The code snippet below demonstrates the download process using the browser:

// Assuming that object uri of type Uri points to
DRM resource.
try
{
Intent browserIntent = new Intent();
// Using explicit intent to avoid
activity selector
// in case of
multiple browsers on handset
ComponentName comp = new ComponentName(
"com.android.browser",
"com.android.browser.BrowserActivity");
browserIntent.setComponent(comp);
browserIntent.setAction(Intent.ACTION_VIEW);
browserIntent.addCategory(Intent.CATEGORY_BROWSABLE);
browserIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
browserIntent.setData(uri);
// Start the browser download activity.
startActivity(browserIntent);
} catch (Exception e) {
//Handle Exceptions
}

One of the limitations of this approach is that browser activity gets launched in the application task stack. If the user dismisses the current activity, the browser activity comes into the foreground and will need to be dismissed using the Back key.
