Android Studio's high-de map for positioning and 3D map display

In the application development, map development is often needed to use the "component", the domestic more famous is Baidu map and the German map.

This blog is about the German map to achieve positioning and 3D map display, and labeling the corresponding location, words not much to say, first look at the effect, in the code.

Effect

First sign up to become a developer (open the Gao de map, click on the developer platform at the bottom), create an app, fill in the appropriate information as required, such as:

En route contains the release version of the SHA1 security Code and beta SHA1 Security Code, the values of both can be seen blog: Android Studio apk Packaging, Keystore.jks file generation, according to the KeyStore key to obtain SHA1 security code

Speak in a very detailed, according to do will be successful to obtain.

First import the Gold jar package

Select the jar package right click on the ADD as Library, see the following code in Build.fradle to indicate the success of the guide package

    compile files(‘libs/AMap_Location_V3.0.0_20160922.jar‘)    compile files(‘libs/AMap_Search_V3.5.0_20160927.jar‘)    compile files(‘libs/AMap_3DMap_V4.1.1_20161019.jar‘)

Code: (Note: The Project code directory to add an interface file Jnilibs OS file to draw the map, specific download source view, it is not described in detail)
