How Encrypting Files Downloaded using Android Shell protects Android apps

On Android, many of the services are provided by the Android shell: a highly privileged processes running in the background on the Android device. Android developers often use the Android shell to perform common tasks. However, operations performed by the Android shell are not controlled by the app, so the developer can’t ensure they have the same standard of protection as the rest of the app.

When apps are using the Android shell’s download manager, files are downloaded and saved through an external service. Appdome’s Secure Download makes sure that the app’s downloads are not sent to the android shell and are executed within the app’s context so that data encryption is applied to all downloaded files. This Knowledge Base Article explains how Appdome Secure Download works and how you can build your apps with this enabled.

We hope you find it useful and enjoy using Appdome!

About Appdome Secure Download

Appdome Secure Download works by “catching” the Appdome Built app request to download and execute the request within the secured app, thus ensuring that Data at Rest Encryption is applied to the downloaded files that will be stored securely on the device.

The developer does not need to do anything. The Appdome Built app with Secure Download enabled will locate the API call to the device’s Download Manager and make sure that files are downloaded securely.
