问题描述

我试图开发使用ArcGIS Android SDK中的离线地图应用。其次在ArcGIS教程website.Since它是一种离线地图广告应用程式，我没有互联网连接测试。但是，当我运行应用程序时，图形页面是空白。它只是显示了一个黑色的屏幕。当我检查了logcat的，它说。

I'm trying to develop an Offline maps application using ArcGis android sdk. Followed the tutorials from the ArcGis website.Since it is an Offline Maps Applicaion, I am testing it without an internet connection. But, when I run the application,the MapView is blank. It just shows a black screen. When I checked the Logcat, It says

R.....ID 0,0-0,0}

我不能从那里，到 server.arcgisonline.com 的请求会明白。我的Java文件和XML文件是如下：

I can't understand from where, a request to server.arcgisonline.com is going. My java file and xml file are as follows

MainActivity.java

public class MainActivity extends Activity {

    MapView mMapView;
    String extern = Environment.getExternalStorageDirectory().getPath();
    final String tpkPath = "/ArcGIS/samples/OfflineRouting/ImageryTPK.tpk";
    TiledLayer mTileLayer;
    GraphicsLayer mGraphicsLayer = new GraphicsLayer(GraphicsLayer.RenderingMode.DYNAMIC);

    RouteTask mRouteTask = null;
    NAFeaturesAsFeature mStops = new NAFeaturesAsFeature();

    Locator mLocator = null;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        mTileLayer = new ArcGISLocalTiledLayer(extern + tpkPath);
        // Retrieve the map and initial extent from XML layout
        mMapView = (MapView) findViewById(R.id.map);

        // Set the tiled map service layer and add a graphics layer
        mMapView.addLayer(mTileLayer);
        mMapView.addLayer(mGraphicsLayer);
    }

}

activity_main.xml中

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <com.esri.android.map.MapView
        android:id="@+id/map"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        initExtent = "-1.3296373526814876E7 3930962.41823043 -1.2807176545789773E7 4201243.7502468005"
        mapoptions.MapType="Topo"
        mapoptions.ZoomLevel="16" />
</RelativeLayout>

和的build.gradle 如下：

apply plugin: 'com.android.application'

android {
    compileSdkVersion 23
    buildToolsVersion "23.0.1"

    defaultConfig {
        applicationId "com.example.lalprakash.offlinearcgismap"
        minSdkVersion 15
        targetSdkVersion 23
        versionCode 1
        versionName "1.0"
        sourceSets.main{
            jniLibs.srcDir 'src/main/jni'
            jni.srcDirs=[]
        }
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    testCompile 'junit:junit:4.12'
    compile 'com.android.support:appcompat-v7:23.1.1'
    compile 'com.android.support:design:23.1.1'
    compile files('libs/arcgis-android-api.jar')
    compile files('libs/arcgis-android-app-toolkit.jar')
    compile files('libs/jackson-all-1.9.0.jar')
}

另外，我放在 TPK 文件在我的内部存储器的根。
请帮助我，因为我需要它实在太差了。谢谢你。

Also, I've placed the tpk file in the root of my internal memory.Please help me as I need it really badly. Thank you.
