Android PDF Signer

Android PDF Signer is an Android App written in Java that:

• given an id, grabs a pdf from a network share to local storage;
• captures the signature using an on screen signature pad;
• appends the captured signature to the pdf;
• saves the resulting pdf to the network share;

Installation

Clone the project from github:

git clone https://github.com/zhoorta/android-pdf-signer.git

Open the project with Android Studio (recommended).

Usage

The app uses a network share (currently only SMB/Samba shares) to grab original (in folder) and save resulting pdfs (out folder). To be used it is necessary to configure the SMB share access with: server, username, password, domain and sharename.

In the main activity the user inputs an ID. The app then searches for a file with the name ID.pdf on the in folder. If found opens the file for preview. Choosing the option to sign, the app opens a signature pad to capture the signature. When saving, appends the signature to the pdf using a configured width, height, page and position on the pdf document. The document is then saved on the out folder of the network share.
