Proton Movies DiffDroid is a Add-On for DiffTool (https://play.google.com/store/apps/details?id=com.difftool) which extends it's functionality.

DiffDroid functions in detail:
- this APP allows DiffTool to open the files and documents in an editor of your choice.
- by using that APP you can start DiffTool from any File Explorer (simply select DiffDroid when you open a file from your Explorer; then press "Select the Second File" to add file B: in the same way).
- this APP offers Java®* intents to integrate DiffTool into any other Java®* App (more about see below).

Coming soon:
- DiffDroid will give DiffDroid access to Google Drive™**
- DiffDroid will give DiffTool access to files on your local network.

For software developers:
By using this APP you can use the following code to integrate DiffTool into your Apps.
