Android Baidu map API integrates basic map and Baidu map api

When I used the Baidu map API to integrate Baidu map, I encountered some pitfalls and opened this post...

Start Code directly

1. Create a project

We recommend that you use! If ES is used, a java. lang. noClassDefFoundError: com. baidu. location. the LocationClient error has been posted on Baidu for half a day. Most of the answers are the same and cannot solve the problem! (This is also a depressing thing for me. Why are there useless things? Some people are still turning around like crazy ...) Therefore, I finally chose to use.

2. Go to the Baidu map Homepage

1) if you do not have an account, apply for a Baidu account

2) download the sample code of Baidu map and decompress it (the download may fail, but there is no way to download it. Just a few more times ...)

Decompress the package as follows:

　　　　　　　　

 

 

3. Integrate the basic map page with the Android map SDK according to the official documentation.

　　　　

 

1) obtain the key

* Click to obtain the key.

　　　　　　　

 

 

* Enter information

　　　　　　　

　　　　

Application name (in project value> String. xml> app_name)

SHA1 value: Command Line WINDOW> keytool-list-v-keystore FilePath (FilePath: Drive C> User>. android> debug. keystore)

　　　　　　　　　　

　　　　　　　　　　

 

Note: if an error 203 is returned, the verification code is incorrect.

Solution: 1. Copy the. APK file at the runtime, change the suffix to zip, and decompress it.

　　　　　　　　　　　　　　　　　　　　

2. Command Line WINDOW> keytool-printcert-file FilePath (FilePath: for example)

　　　　　　　　　　　　　　　　　　　　

3. To get the SHA1 value, it is best to re-create the application on the Baidu map open platform to obtain a new key (remember to modify it in AndroidManifest. xml)

 

Package name: AndroidManifest. xml

　　

* Get a key.

　　　　　　　

2) Configuration

* Import the jar package and reference it

　　　　　　　

 

* Insert the following code in build. gradle> android:

 sourceSets {        main {            jniLibs.srcDirs = ['libs']        }    }

　　

* Add a development Key to the application.

<Meta-data android: name = "com. baidu. lbsapi. API_KEY" android: value = "Developer key"/> <! -- This developer key is changed to the key obtained by the application created above -->

* Add required permissions

<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/><uses-permission android:name="android.permission.INTERNET"/><uses-permission android:name="com.android.launcher.permission.READ_SETTINGS" /><uses-permission android:name="android.permission.WAKE_LOCK"/><uses-permission android:name="android.permission.CHANGE_WIFI_STATE" /><uses-permission android:name="android.permission.ACCESS_WIFI_STATE" /><uses-permission android:name="android.permission.GET_TASKS" /><uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/><uses-permission android:name="android.permission.WRITE_SETTINGS" />

* Add a map control to the layout xml file.

1 <com.baidu.mapapi.map.MapView  2     android:id="@+id/bmapView"  3     android:layout_width="fill_parent"  4     android:layout_height="fill_parent"  5     android:clickable="true" />

 

* Initialize the Context global variable referenced by the SDK when creating an application to manage the map Lifecycle

Public class MainActivity extends Activity {MapView mMapView = null; @ Override protected void onCreate (Bundle savedInstanceState) {super. onCreate (savedInstanceState); // initialize the context information before using the SDK components, and pass in the ApplicationContext // note that this method must be implemented before the setContentView method. initialize (getApplicationContext (); setContentView (R. layout. activity_main); // obtain the map control reference mMapView = (MapView) findViewById (R. id. bmapView) ;}@ Override protected void onDestroy () {super. onDestroy (); // execute mMapView when onDestroy is executed in activity. onDestroy () to implement mMapView for map lifecycle management. onDestroy () ;}@ Override protected void onResume () {super. onResume (); // execute mMapView when onResume is executed in the activity. onResume () to implement mMapView for map lifecycle management. onResume () ;}@ Override protected void onPause () {super. onPause (); // execute mMapView when onPause is executed in activity. onPause () enables mMapView for map lifecycle management. onPause ();}}

 

After completing the preceding steps, run the program to display the following map in your application:
