**Custom Mavlink**

Make modifications to definitions xml file for mavlink. From there run mavlink generator script. In generator choose c+. I also deselected validate because it would see enum errors otherwise

**QT and Android Integration**

Install android studio Install dependencies:

`sudo apt-get install libstdc++6:i386 libgcc1:i386 zlib1g:i386 libncurses5:i386`

`sudo apt-get install libsdl1.2debian:i386 Go get jdk 11 and note location`

In QT creator go to manage kits, then devices, then android.

-Browse to jdk location

-setup sdk

-select to download openssl

To debug on phone enable developer options (usually tap build number 7 times)

-Enable “usb debugging” on phone

-Give permission when you plug phone into computer via usb

Now when you build in QT and your phone is connected the app will launch in debug mode on your phone.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://openhd.gitbook.io/open-hd/master/developer-corner/qopenhd-and-custom-mavlink.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
