Here is an update for the development of the Droidplanner app, the first post can be read?here.
What I have done so far is:
- Auto-waypoint generation (hatch filling) just like Mission Planner.?
- Codded a?MAVlink v1.0 parser in Java, including a python script for the?MAVlink generator?to generate the necessary Java classes.
- TCP communication, all handled in an android service with the MAVlink packets being delivered to the U.I. via messages. (This structure is based on Bart's code). The entire communication?is logged to a *.tlog file on the?SD-card.
- HUD screen, just added the HUD designed by Bart.
- Fight Data screen with the current GPS position and?heading of the drone?overlayed?in a map (the drone rotates). (I hope the designer of the icons on Mission Planner doesn't complain that i used them, where else would I find such nice?graphics)
- Waypoint sending and receiving to the APM board (by the way i use a APM1 board)
How to test it
Note: The app is in development, and I haven't yet tested it on the field. I take no responsibility?from any damage.
I like the idea of WiFi because it's a wireless connection to a tablet (and?available?on all android devices), all that is needed is a WiFi router (really?cheap these days, and could be used for other?purposes?in the field) and a Serial-TCP bridge. This adds the possibility of using multiple GCS on the network.
Other options for the Serial-to-TCP bridge are (I have not tested any of these yet):
How to?Collaborate:
- Download the source code from?GitHub. (I changed it to it's own repository, to avoid messing up with my ardupilot repo, but in the process I lost the commit history)
- Read the read-me on the project folder, it's?really?simple to start developing (Just importing the project to eclipse?basically).
- Chose something to fix or improve and do it.

The big question!
When I started this project there was no other active project on DiyDrones for developing a Android GCS. There was Bart?copter-gcs, but since there was no more?support?(and because I don't have Bluetooth on my tablet, what was necessary) I decided to start codding a app. (even?without?much?knowledge?of Java).
Soon after my?release, Kevin Hester?released?an app he was developing:?Andropilot. Thanks to his amazing codding the app is great.
I keep developing my app for two reasons:
- I had just started learning Java and the Android SDK, Andropilot is written in Scala. This would greatly complicate my beginner life.
- I wanted to keep the project in a state I could support it all. And that it could be?easily?maintained?by others, in the hope it could join the DiyDrones codebase. (Currently all that is needed to develop is the android SDK)
So my big question is in fact two:
- What language is easier to be maintained for this?community?
- Should I drop DroidPlanner, and start developing with Kevin?
