ProtonMail for Android

What

Well, well, well. let's take a look:

private, encrypted email.
emails stored encrypted and sent encrypted whether possible
uses Google APIs (Google Play Services and whatever) on the Android app to enable notifications
attachments and sending messages require the device to have full network access (in other words, being able to ping Google)

do you see the irony?

Setup

The most straightforward way to build and run this application is to:

Install Android Studio: https://developer.android.com/studio/install
Clone the repository. You have two options:
- Use the Project from version control in Android Studio, or
- Use the git clone command and import it into Android Studio
Build and run the app directly in Android Studio

Alternatively, if you want to build the app directly from the command line (or using a different IDE, etc.), you will first need to install the command line tools from: https://developer.android.com/studio#cmdline-tools. Then you will need to install the SDK using the sdkmanager tool. After cloning the repository with git clone you will need to edit the local.properties file so that it points to the location of the SDK. Depending on which operating systems you use, the location of the SDK is usually:

Windows: C:\Users\<username>\AppData\Local\Android\sdk
MacOS: /Users/<username>/Library/Android/Sdk/
Linux: /home/<username>/Android/Sdk/

Then, go to the app’s root directory in the command line tool and run:

./gradlew assembleBetaDebug
adb install ./app/build/outputs/apk/beta/debug/ProtonMail-Android-1.XX.X-beta-debug.apk

Note: In app notifications when building from source

We may offer alternative push notification systems in the future which do not rely on Google services.

this fork does it.

Contributions

Contributions are appreciated, but what? this will live as a fork forever, so the only guideline is too keep your code clean-looking.
