With a newer Android version you actually have to include the permission for coarse location as well

I fixed that in the last commit

Consider to include the position_covariance as well to enable the user to use this widget in conjunction with fused odometry.

I have to check how to get these info
| final boolean networkEnabled = locationManager.isProviderEnabled(LocationManager.NETWORK_PROVIDER); | ||
|
|
||
| if(gpsEnabled) | ||
| locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 0, 0, locationListenerGps); |

Here it would be nice, if the user can control the minimum distance/time via widget parameters to reduce the drain on the device battery.

With the fused provider it is slightly different. I will try to export these parameters in the widget if we decide to keep this version using the LocationManager.

Is this something the user should control via parameters from the config?

Text and rotation can be changed by the user

Thing to discuss: |
Thank you! :)
Actually there is a problem with that: the publisher stops when the phone locks. It would be nice to have the publisher running in the background even if the phone locks. I was thinking to embed the I will work on the changes in the next days. Thank you again for your amazing work and suggestions. |

I made other two branches to test the new google API for the fused location and to test foreground services with the Here are the branches: https://github.com/graiola/ROS-Mobile-Android/tree/fused https://github.com/graiola/ROS-Mobile-Android/tree/service I think the fused method is better because requires way less code to get the current location, moreover it has a way to define the publishing interval. |

Add a widget to publish the phone's coordinates to ROS.
It needs testing and a good code review because I am not an android developer :P
It would solve #98 and #79
