Since the app records GPX 1.0, can it also log the speed?

The first two releases do not install ADB says [INSTALL_PARSE_FAILED_NO_CERTIFICATES].
Latest install on 4.4.2 but do not run. No idea what log to post here. It is a really interesting recorder for bike! Hope to see it work.

Hi, Thanks for sharing such great app.
In some cases, it is important to the lat and long at a specific frame. for example garmin dashcam uses a RIFF files to store gps and acceleration data in the same video file (take a look at here) but I think that would be hassle while it could be saved in another xml file.

I would like to suggest you to include other sensors as well to output, which user can use it for post process:

• Gyroscope
• Comass
• Accelerometer

Also something for syncronizing the video with the data. An .xml output would be best i think. maybe something like this:

<Datas videoFileName="abc.mp4">
  <Data frameNumber="120">
      <gps lat="1.23" lon="3.45" alt="6.78" speed="9.01"/>
  </Data>
  <Data frameNumber="154">
      <accel x="1.23" y="3.45" z="6.78"/>
  </Data>
  <Data frameNumber="154">
      <compass x="1.23" y="3.45" z="6.78"/>
  </Data>
  <Data frameNumber="200">
      <gyro x="1.23" y="3.45" z="6.78"/>
  </Data>
<Datas>

Each <Data> element relates to a sensor data and relates to a specific frame of video. not sure but i think it would be easy to find out the frame number of video. For example user knows if video file is 24 frame per second, the frame number 120 relates to 5'th second of video. (120 / 24 = 5)

The content of <Data> element is either gps, accel, compass or gyro elements.
this way one can very precisely synchronize the data with video output for post process.

Add option to export a journey as an mp4 video , with location embedded in corner.

Drawbacks to consider:

• Including FFMpeg can increase size of APK significantly (15mb - 80mb)
• Exporting is CPU heavy especially for longer videos.

Does the application have a timelapse mode? If not, asking for a feature request to implement that, as longer journeys can create very large video files.

Trying to install in Droid-ify 0.5.6 on a Samsung A71 5G UW running Android 13 and I get "Unknown error. INSTALL_PARSE_FAILED_MANIFEST_MALFORMED: Failed parse during installPackage..."

It seems that all you releases identify as version 1.0, versionCode 1 (because of these lines in your build.gradle). This not only makes it hard for the users to tell which version they're running, Android itself wouldn't accept a newer version as "update" if versionCode wasn't increased.

So could you please make sure that future versions have those values set appropriately? The current one would be expected to have these values set to "1.1.2" resp. "4". Thanks!
