When talking about eReaders, most people would say that I like Kindle or I like iPad. Yes they are well-known among ebook lovers. But, we can't deny that there are a part of people who are using android tablets or smart phones to read eBooks.

So as a writer about eBooks, in today's article let me write some good tips for those android lovers please. Here what I deal with is how to read drm epub on android tablet.

Go straight to the topic, I will introduce you 2 ways available. Just choose the method you like.

Method 1: Install DRM supported ePub reader apps

Here I want to settle this problem with 2 sorts: 'special apps' and 'general apps'.

Official apps:

Here I mean those apps released from official ebook stores, such as Kobo, Nook, Sony, etc. These apps are special because they are only provided for their own books. For example, if we use Kobo app, we can only read books bought from Kobo store. And if we want to read other books bought from public websites, we have to install extra apps.

General apps:

This kind of epub reading apps are widely used on our devices because they are not dedicated to the store. Whether can we read one book is not depended on where this book purchased from, but depended on what format this book is, and what DRM this book is protected by. For example, the Aldiko, it can read all books if they are in epub or pdf format with Adobe drm.

The biggest benefit of these apps is that there is no need for us to install additional apps. We can even say that just with these apps we can read books from all over the stores.

Here is a simple list for epub reading apps on android.

epub reader for android	supported DRM	Price
Official apps	Google Play Books to Google	Free
	Adobe DRM, kobo DRM
	Adobe DRM; Nook DRM
	Only support books purchased from their own stores (*1)
General apps	Adobe DRM
	$6.99 (Premium) / Free
	Adobe DRM
	Free
	DRM Free
	$4.99 (pro) / Free
	Must make sure the DRM kind when deciding which app to use (*2)

*1: In March 2014, Sony abandoned all the US and Canada market, so those Sony eReader users have to transfer Sony to Kobo.

*2: There are many other general apps that you can use and install from google play stores.

From this list you know there are so many epub reading apps for android tablet. So you may feel a little difficult to select one. Here is my own advice:

If you just read books from only one store, choose the stores own android app from special apps. Here I take Kobo Android App for example.

Step 1. Download Kobo Books - Reading app for Android. You can download it from website or through Google Play on your android devices.

Step 2. Register with your Kobo account in Kobo for Android app .

Step 3. Sync Kobo books to your tablets or smartphones via wifi.

If you read books purchased from many bookstores, choose a suitable epub reader app from general apps.

Method 2: Removing DRM from EPUB

You may only want to install one reading app to read all ebooks on phones or tablets, but the books were bought or download from different eBook store, in this case, remove the drm from epub books is the best choice.

From the form above you may have found that after we got drm epub files, they may be with 2 kinds of DRM: Adobe DRM, KOBO DRM and Nook DRM.

So if we got a tool that helps us remove the three drm limitation, our epub books will be free to read.

Here I recommend you this All DRM Removal tool. It can strip both adobe and Kobo drm protection fast and perfect.

At first get the tool downloaded and installed for free.

First, you need to know that we can't strip the DRM protection directly from anroid device, then the books should be downloaded and handled on computer.

1Remove Adobe DRM from ePub books

Great majority of epub books are protected by Adobe DRM, including Kobo, Google play books, some Nook books, and many small book store.

Step 1: Install Adobe Digital Editions, and then authorize it with the same Adobe ID (Normally, it's the same email address as your eBook store's account).

Step 2: Download the title from ebooks store, make sure you can read epub files on computer ADE.

Step 3: Install All drm removal and add epub books (below the ADE icon at right side) to the drm removal tool.

The rest of work is very simple, just drag the books to main interface and click 'Remove DRM' button, wait about a seconds, you will get a drm free books to read on any devices.

2Remove Kobo DRM from Kobo ePub/PDF books

Kobo books downloaded via Kobo desktop application will be encrypted with Kobo DRM. All DRM Removal aslo can help you remove Kobo DRM easily with just one click. First of all, please ensure your Kobo books have been downloaded successfully.

After your Kobo books has been downloaded successfully, they will display under Kobo tab in the left column. Just drag and drop them to the main interface. DRM will be removed.

3Remove Nook DRM from Nook ePub books with Nook DRM Removal

Few epub books purchased from B&N store are protected with Nook DRM.

Step 1: Sync the Nook epub books from Nook app ( from Microsoft Windows store). Note: this is the only way to download Nook books to computer successfully.

Step 2: Download nook books to computer and find them. The default download folder is 'My Barnes & Noble eBooks' in library.

Step 3: Install and launch Nook DRM Removal. The tool will automatically detect Nook books on your computer and upload them. Then just drag the books to the main interface of this program and click 'Remove DRM' button to open output folder.

Note: In order to remove Nook DRM successfully, please send your Nook account email and password to Epubor Team (support@epubor.com). You will receive a Nook key file from Epubor Team within 24 hours. All the following decryptings will only use this Nook key file. Then add your key file to.Epubor _keys folder here: C:Usersyourusername.Epubor_Keys.

After DRM was removed, you can get the free epub books from the pop-up window. Then what you need to do is just to transfer them to your android tablet or smartphones, and select a reading app as you like to open them.

This document provides an overview of the Android digital rights management (DRM) framework andintroduces the interfaces that a DRM plugin must implement. This document doesn'tdescribe robustness rules or compliance rules that may be defined by a DRMscheme.

Framework

The Android platform provides an extensible DRM framework that letsapps manage rights-protected content according to the licenseconstraints associated with the content. The DRM framework supports many DRMschemes; which DRM schemes a device supports is up to the device manufacturer.The DRM framework provides a unified interface for application developers andhides the complexity of DRM operations. The DRM framework provides a consistentoperation mode for protected and nonprotected content. DRM schemes can definecomplex usage models by license metadata. The DRM framework provides theassociation between DRM content and license, and handles the rights management.This enables the media player to be abstracted from DRM-protected ornonprotected content. See MediaDrmfor the class to obtain keys for decrypting protected media streams.

The availability of rich digital content is important to users on mobile devices. Tomake their content widely available, Android developers and digital contentpublishers need a consistent DRM implementation supported across the Androidecosystem. To make that digital content available on Android devices and toensure that there's at least one consistent DRM available across all devices, Google providesDRM without license fees on compatible Android devices. The DRM plugin isintegrated with the Android DRM framework and can use hardware-backed protectionto secure premium content and user credentials.

The content protection provided by the DRM plugin depends on the security andcontent protection capabilities of the underlying hardware platform. Thehardware capabilities of the device should include hardware secure boot toestablish a chain of trust of security and protection of cryptographic keys.Content protection capabilities of the device should include protection ofdecrypted frames in the device and content protection through a trusted outputprotection mechanism. Not all hardware platforms support all of the abovesecurity and content protection features. Security is never implemented in asingle place in the stack, but instead relies on the integration of hardware,software, and services. The combination of hardware security functions, atrusted boot mechanism, and an isolated secure OS for handling securityfunctions is critical to providing a secure device.

Architecture

The DRM framework is designed to be implementation agnostic andabstracts the details of the specific DRM scheme implementation in ascheme-specific DRM plugin. The DRM framework includes simple APIs to handlecomplex DRM operations, acquire licenses, provision the device,associate DRM content and its license, and finally decrypt DRM content.

The Android DRM framework is implemented in two architectural layers:

• A DRM framework API, which is exposed to apps through the Android application framework.
• A native code DRM framework, which exposes an interface for DRM plugins (agents) to handle rights management and decryption for various DRM schemes.

See AndroidMedia DRM andAndroid Media Crypto for more details.

DRM Plugins

At system startup, the DRM framework scans for HAL instances/services (described in .rc files)and plugins are discovered through the HIDL registry. Media DRM Server(mediadrmserver) creates both CryptoHal and DrmHal objects.CryptoHal and DrmHal then call the plugins with vendor-specific implementations.

Plugins should implement binderized HALs. Binderized HALs use theHAL interface definition language (HIDL),which allows the framework to be replaced without having to rebuild HALs.

Plugins are built by vendors or SOC makers and put in a /vendor partition onthe device. All devices launching with Android 8.0 or higher must support binderized HALs writtenin the HIDL language.

Implementation

Drm Video Downloader For Android 8 1

To implement new DRM frameworks APIs by a plugin:

1. Add plugin service to the device’s build files.
2. Update the device manifest.
3. Add SELinux permissions.
4. Create a .rc file under /vendor.
5. Implement the plugin.

APIs are defined in each version of IDrmPlugin.hal, ICryptoPlugin.hal, IDrmFactory.hal, and ICryptoFactory.hal

Adding plugin service to device build files

For example, to add interface 1.3 support, the VENDOR DEVICE/device.mk file must include the android.hardware.drm@1.3-service.* packages:

Versions 1.0 to 1.2 are deprecated in R / Android 11. Devices upgrading to R are still allowed to run versions 1.0 to 1.2. However, new devices launching with R must run only version1.3.

Updating the device manifest

The vendor manifest.xml file for the device must include the following entries:

Alternately, we recommend using vintf_fragments.

Adding SELinux permissions

1. Add to VENDOR DEVICE/sepolicy/vendor/file.te
   
2. Add to VENDOR DEVICE/sepolicy/vendor/file_contexts
   

   We recommend using regular expressions to specify the version numbers to avoid making updates for new releases, for example:

   Alternately, update the version numbers as shown below.

3. Add to device/sepolicy/vendor/hal_drm_clearkey.te
   

Creating an .rc file under /vendor

The .rc file specifies the actions to be taken when a service is launched.

See Android Init Language for details.

Implementing the plugin

1. Implement the main() entry point in service.cpp of the pluginservice.
2. Implement ICryptoPlugin, IDrmPlugin, ICryptoFactory, and IDrmFactory.
3. Implement the new APIs in the plugin.

DRM plugin details

DRM plugin vendors implement DrmFactory, CryptoFactory, andDRM plugin.

DrmFactory

The DrmHal class searches for registered DRM plugin services and constructscorresponding plugins that support a given crypto scheme through the DrmFactoryclass.

IDrmFactory is the main entry point for interacting with a vendor's drm HAL through the createPlugin API. The createPlugin API is used to create IDrmPlugin instances. The 1.3 IDrmFactory must always create 1.2 IDrmPlugin interfaces, which are returned via the 1.0 createPlugin method.

New in 1.3 IDrmFactory, getSupportedCryptoSchemes returns a list of supported crypto schemes for the HIDL drm HAL instance.

Determines if the plugin factory is able to construct DRM plugins that support a given crypto scheme, which is specified by a UUID.

Determines if the plugin factory is able to construct DRM plugins that support agiven media container format specified by mimeType.

Constructs a DRM plugin for the crypto scheme specified by UUID.

CryptoFactory

The CryptoHal class searches for registered DRM plugin services and constructscorresponding plugins that support a given crypto scheme through the CryptoFactoryclass.

Determines if the crypto factory is able to construct crypto plugins that support a given crypto scheme, which is specified by a UUID.

Determines if the plugin factory is able to construct crypto plugins that support a given crypto scheme, which is specified by a UUID.

DRM plugin

The APIs are defined in hardware/interfaces/drm/VERSION/IDrmPlugin.hal. The corresponding IDrmPlugin.h file can be found inout/Soong after the build.
