priority, GPS is used for positioning first. If GPS positioning is not enabled or there is no available location information, and the network connection is normal, the positioning SDK returns the optimal result of Network Positioning (that is, Wi-Fi and base station. To make the obtained Network Positioning results more accurate, turn on the Wi-Fi switch of your mobile phone.The following two classes are used: MyLocationOverlay and PopupOverlay.1.

Android commonly used three positioning methods are: based on GPS positioning, base station status, based on WiFi location. 1, based on GPS positioning:GPS positioning needs GPS module (hardware) support, no GPS module is unable to GPS positioning.GPS positioning the biggest advantage is its high positioning accuracy (general error in 10m), No network can also be used ; The disadvantage is high power consumption, slow positioning, indoor and basement

We know that the Android NDK program will generate a tombstone backtrace when it crashes (or take advantage of the ADB Logcat Crawl), and from this backtrace we can see which function caused the crash, but usually because we publish it is Rele ASE version, can not take advantage of the address information in the BackTrace directly to the source code and line number, when the error that caused the crash is not very obvious, for us to solve the problem
