get gps coordinates android

We go online search Android location is null can not locate the problem, there is an estimated a lot of articles about how to solve, but in the end we found that basically useless. This article will be based on the principles of Android positioning to deeply analyze the reasons and propose a real solution. Before we go into the analysis, we must first look at the official

Welcome to add ArcGIS API for Android QQ Exchange Group: 337469080First talk about the reasons for writing this article, in the process of discussion in the group, someone mentioned the problem of positioning, just, I have done related work when the relevant things, so summed up, to share out, because I level limited, the bug is unavoidable, but also hope that a higher high man criticized. Nonsense not much to say, directly into the subject.To locate

Recently, GPS is being used on Android. It is always difficult to get up or down, no data, and debugging is in progress. Therefore, we carefully analyzed the code from top to bottom. The soul function is The requestlocationupdates function is mainly used to start a monitor and listen for location change information. Not much nonsense. Start analysis. 1. First fi

The Android coordinate origin is the upper-left corner, and if it is a view, then the upper-left corner of the matrix is the origin.1.

Summary1. I found that the Left, right, top, and bottom values of the view are different from those of the invalidate process. Now I want to analyze the specific meanings of these values. 2. Understand coordinates. The concept of position involves the concept of coordinate system. In a two-dimensional view, the coordinate system combines the X axis and Y axis to represent the absolute sit of a certain point. 1. Confused During the invalidate process o

Baidu map android sdk3.5 allows you to locate and jump to the specified coordinates and add tags A few days ago, I downloaded the new Baidu map sdk, version 3.5, and found that the Baidu map api has changed significantly. Similar to version 3.0 However, setting the map center and adding the maker tag have greatly changed. Set map center point // Define the map state zoom to indicate the zoom Level 3-18MapS

This article illustrates how Android obtains the current view's coordinates in the screen. Share to everyone for your reference. Specifically as follows: Final int[] location = new Int[2]; View.getlocationonscreen (location); This allows you to get the X,y value of the view in the global coordinate system (note that this value is to be counted from
