"The geocoder class requires a backend service that is not supported in the core Android framework. The geocoder query methods will return an empty list if there no backend service in the platform."
Here we have mentioned that we need to have a backend service, but we have some suggestions on how to get this service. Some people in the Forum think we should use G

Parse maps longitude and latitude using JSON in Android
This error occurs when you use geocoder in googlemaps to reverse the longitude and latitude of a geographical location,"The service is not available" geocoder returns the list as null, and the street information is not obtained. In fact, there has been a bug in the getcoder reversal of latitude and longitud
Quick query of geographic locationThe Geocoder component provides a quick, geographically-based query that can be queried to display the geographic location of a map by entering an address by adding a query input box. Using Geocoder to move the map display to the specified location area is faster than panning and blooming maps. This feature requires the use of the locator service (location services).Prerequ

Android development: LocationManager's process of obtaining longitude and latitude and positioning (with demo)Location functions are often used in Android development, especially those that depend on the location function. Many people prefer Baidu map and AMAP sdks and open APIs, however, if you only need information such as longitude and latitude, city, street address, and other information, you do not nee

Use Baidu map Android sdk's high-imitation sending location function
I have been in touch with the Baidu map development platform for half a month. These two days I tried to imitate the location sending function to my friends, and the operation capability on Baidu maps has taken another step.
(If you need a complete demo, leave a comment to your mailbox)
I encountered some difficulties when implementing this function, which may also be difficult for

You must click an address to directly call Baidu map and display the address on Baidu map. The parameter has only one address and no corresponding coordinates, this reminds me that the previous map was used to transmit a coordinate and display the address on the map. The idea was as follows: how to convert a detailed address to a coordinate, and then it is sent to Baidu map, but it seems that although the detailed address can be converted into coordinates, but this is converted after the display
