Implementation of Google Maps API encoding line algorithm In the secondary development of Google Maps API, we encountered the encoding line algorithm problem through gpolyline. fromencoded can effectively improve the rendering speed. based on the fact that there is no relevant implementation on the internet, I will give the algorithm of latitude and longitude and level in the encoding line for your refere

Today, I met a line of code to open a webpage, which is much easier to implement than the uiwebview control in my impression. It is easy to use and can be easily used after real machine testing, I searched for some related information on the Internet: Code segment: [[uiapplication sharedapplication] Openurl: url]; The system URL includes:1.

The steps are as follows: Prerequisites: Each Google Maps API Key corresponds to an MD5 fingerprint (fingerprint Certificate). That is to say, before obtaining the map API Key, you must use the keytool provided by Java JDK to generate an MD5 fingerprint. (Does sun have long known that Google will make such a thing? Why was this keytool used earlier ?) Now that this fingerprint is used, apply for one! Keytool is placed in the bin/directory of the java

Who determines the number of Hive maps or the number of MAPREDUCE maps? Inputsplit size, how is the inputsplit size calculated? This is the key to adjust the number of maps.Hadoop provides the Inputformat interface to describe the format of input data. One of the key methods is getSplits, which partitions the input data.Hive encapsulates InputFormat: The specific implementation is determined by the hive. in

In, I wrote an offline Google Maps API Development Kit (GMAP can be developed without a network). Later, liongis reorganized a new package, even an offline package of V3. Today, on the basis of liongis, I have reorganized and released an offline Development Kit for you. Compared with the liongis offline package, I only upgraded the version from 3.4.x to 3.8.2, this should be the latest package at the present stage. The simplest difference is that when

To display Google Maps on the android client, you need to use Google's API. This time, Google is directly used instead of the android SDK.

Here are the effects of adding two maps to the page: The core code of the page is as follows: Copy codeThe Code is as follows: The code above can display two side-by-side maps on the same page. If you want to drag or scale the map on the left, the map on the right will also move and zoom, you only need to register the zoomend and moveend events for the map on the left. The Code is as follows: Copy code
