android - HERE Maps Android 集成，MISSING_LIBRARIES 错误

Question

我按照步骤 https://developer.here.com/mobile-sdks/documentation/android/topics/app-simple-android-studio.html

但我收到错误消息:无法初始化 map fragment MISSING_LIBRARIES

map 初始化代码:

mapFragment.init(new OnEngineInitListener() {
            @Override
            public void onEngineInitializationCompleted(OnEngineInitListener.Error error) {
                if (error == OnEngineInitListener.Error.NONE) {
                    // retrieve a reference of the map from the map fragment
                    map = mapFragment.getMap();
                    // Set the map center to the Vancouver region (no animation)
                    map.setCenter(new GeoCoordinate(49.196261, -123.004773, 0.0),
                            Map.Animation.NONE);
                    // Set the zoom level to the average between min and max
                    map.setZoomLevel(
                            (map.getMaxZoomLevel() + map.getMinZoomLevel()) / 2);
                } else {
                    System.out.println("ERROR: Cannot initialize Map Fragment " + error.toString());
                    Toast.makeText(MainActivity.this, " Error: " + error.toString(), Toast.LENGTH_LONG).show();
                }
            }
        });

渐变代码

apply plugin: 'com.android.application'

android {
    compileSdkVersion 22
    buildToolsVersion "22.0.1"

    defaultConfig {
        applicationId "com.chethan.mobileapp.startmap"

    compile 'com.android.support:design:22.2.1'
    compile files('libs/HERE-sdk.jar')
    compile files('libs/jts-1.14.jar')

我相信您看错了文档。在这个页面上:https://developer.here.com/documentation列出了两个版本的 HERE Android Mobile SDK，适用于 Android Starter 的 SDK 和适用于 Android Premium 的 SDK。当我认为您需要 Premium 时，您正在查看 Starter 的文档。

Premium SDK 有一个本地库组件，需要包含在构建中。试试这个页面:https://developer.here.com/mobile-sdks/documentation/android-hybrid-plus/topics/app-simple-android-studio.html (“将 HERE SDK 库添加到您的项目”部分)

具体来说，我相信这些是您错过的部分:

• From the directory where you installed the HERE SDK, copy the contents of the HERE-sdk/libs/armeabi-v7a folder to your project's app/src/main/jniLibs/armeabi folder. You need to create the jniLibs and armeabi subfolders.

• Within the same section in your AndroidManifest.xml file, add the following lines:

  <service
android:name="com.here.android.mpa.service.MapService"
android:label="HereMapService"
android:process="global.Here.Map.Service.v2"
android:exported="true" >
<intent-filter>
<action android:name="com.here.android.mpa.service.MapService" >
</action>
</intent-filter>
</service>

更新

从 HERE SDK 版本 3.3 开始，SDK 作为 Android 存档 (AAR) 文件提供。因此，您不再需要像上面第一个项目符号中提到的那样手动复制 native 库。您只需将 AAR 文件包含在您的build.gradle 文件。例如:

// Assuming you have placed the HERE-sdk.aar in a folder 'libs'
repositories {
    flatDir {
        dirs 'libs'
    }
}

dependencies {
   ...
   compile(name: 'HERE-sdk', ext: 'aar')
   ...
}
