Android GPS does not work until restart on new phones

由 陌路散爱 提交于 2019-12-09 06:32:13
问题 I have posted about this issue before, and found a few other people who have had the same issue with no solutions found. I am developing an Android app that submits a JSON query to a server with the obtained GPS coordinates and geocoded Zip Code. For brand new users that have never downloaded the app, GPS does not work whatsoever. It is not until rebooting the phone that GPS will work. After installing the app and then rebooting, the GPS will work every time without problem, even if they

问题 I went through many similar questions on Stackoverflow and other websites and I based my solution on those answers but I still can't get it to work… My problem: I want to determine whether or not a certain GPS location P lies within a rectangular area bounded by four given GPS coordinates A , B , C , D . At the moment I am calculating the areas of triangles ABP , BCP , CDP and DAP . If any of those areas is bigger than zero (don't be upset, mathematicians) the point lies outside my rectangle

Battery life if using GPS and background app ios/android

I'm trying to see if it would be worth the time to create an app for myself but if i work for 8 hours and dont have a way of charging my phone during that time then i dont want to be going home and it shut down on me since my app i would create works at

问题 I want to find the intersection points of two Locations in Android. I don't want to consider cases where the circles as shown in the Figure don't intersect or are included or are completely overlapping. My problem is that the Location is given in degree and the radius (accuracy) is given in meter. I do not know how to mix those Units. In my case the environment is Android, but the Problem is not Android specific. 回答1: You have to convert latitdue, longitude to a cartesian coordinate system,
