Android Studio configuration using Baidu API (with simple example)

Or with the students to develop the course work of the program app, to use the Baidu map API

However, the official documentation seems to be only an example of eclipse, which does not seem to explain to Android studio. Is it because the latter is the product of "Doodle"? Oh

The use of the API is simple. Class field and method, the official documentation has been given in detail.

And before your app uses the API, you need to apply a key to your app on the Baidu map developer's website, or the server won't talk to you. These official documents are all there, so don't dwell on them.

In the SDK above, just pick a version to download, I'm under the latest version 5.1

To get a folder Baidulbs_androidsdk_lib, the directory structure is as follows:

This leaves two questions:

1. How to configure the jar files and so files in the downloaded SDK into Android Studio

2. How to configure Manifest

Workaround:

1. Place the jar file in the Libs directory of Project structure:

Right-click the jar file and add it to the library (add as libraries)

Then, create a subdirectory under Libs: Armeabi, put the so file into this subdirectory

2. Androidmanifest.xml configuration, the official documentation of the demo inside. But if you don't bother, look down and change a little.

In manifest, add a child element:

<uses-permissionAndroid:name= "Android.permission.BAIDU_LOCATION_SERVICE"></uses-permission>    <uses-permissionAndroid:name= "Android.permission.ACCESS_COARSE_LOCATION"></uses-permission>    <uses-permissionAndroid:name= "Android.permission.ACCESS_FINE_LOCATION"></uses-permission>    <uses-permissionAndroid:name= "Android.permission.ACCESS_WIFI_STATE"></uses-permission>    <uses-permissionAndroid:name= "Android.permission.ACCESS_NETWORK_STATE"></uses-permission>    <uses-permissionAndroid:name= "Android.permission.CHANGE_WIFI_STATE"></uses-permission>    <uses-permissionAndroid:name= "Android.permission.READ_PHONE_STATE"></uses-permission>    <uses-permissionAndroid:name= "Android.permission.WRITE_EXTERNAL_STORAGE"></uses-permission>    <uses-permissionAndroid:name= "Android.permission.INTERNET"></uses-permission>    <uses-permissionAndroid:name= "Android.permission.MOUNT_UNMOUNT_FILESYSTEMS"></uses-permission>    <uses-permissionAndroid:name= "Android.permission.READ_LOGS"></uses-permission>

In application, add a child element:

<ServiceAndroid:name= "COM.BAIDU.LOCATION.F"android:enabled= "true"android:process= ": Remote" >        <Intent-filter>            <ActionAndroid:name= "com.baidu.location.service_v2.2" >                </Action>        </Intent-filter></Service><!--Meta-data needs to be written in application. -    <Meta-dataAndroid:name= "Com.baidu.lbsapi.API_KEY"Android:value= "Please enter the key for the application" />

Is it a little strange to feel the config file? But it worked.

Now you're ready to write code using the API normally.

Here, give me a simple example of its function is to get the current latitude and Longitude button once per click.

Xml:

<LinearLayoutxmlns:android= "Http://schemas.android.com/apk/res/android"Xmlns:tools= "Http://schemas.android.com/tools"Android:layout_width= "Match_parent"Android:layout_height= "Match_parent"Tools:context=". MyActivity "    >    <TextViewAndroid:id= "@+id/show_position"Android:text= "@string/hello_world"Android:layout_width= "Wrap_content"Android:layout_height= "Wrap_content" />    <LinearLayoutAndroid:layout_width= "Match_parent"Android:layout_height= "Wrap_content"android:orientation= "Horizontal"android:gravity= "Center_horizontal"        >        <ButtonAndroid:id= "@+id/control_button"Android:layout_width= "Wrap_content"Android:layout_height= "Wrap_content"Android:text= "Get pos per click"Android:layout_marginleft= "100DP"            />    </LinearLayout></LinearLayout>
