实现OpenStreetMap时出错

Question

我正在尝试在android studio中实现OpenStreetMap。我成功添加了库，如下所示。

这是我的MainActivity：

$("#optionNetFlow")[0].selectize.clear();

这是我的build.gradle文件：

package com.example.re.osm;

import org.osmdroid.views.MapController;
import org.osmdroid.views.MapView;

import android.app.Activity;
import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;

import com.example.harjotkaur.osm.R;

    public class MainActivity extends Activity {

        private MapView myOpenMapView;
        private MapController myMapController;

        /** Called when the activity is first created. */
        @Override
        public void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            setContentView(R.layout.activity_main);

            myOpenMapView = (MapView)findViewById(R.id.openmapview);
            myOpenMapView.seharjotkaurtBuiltInZoomControls(true);
            myMapController = myOpenMapView.getController();
            myMapController.setZoom(4);
        }

    }

这是我的清单文件：

apply plugin: 'com.android.application'

android {
    compileSdkVersion 26
    buildToolsVersion "26.0.0"
    defaultConfig {
        applicationId "com.example.re.osm"
        minSdkVersion 15
        targetSdkVersion 26
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    compile fileTree(include: ['*.jar'], dir: 'libs')
    androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
        exclude group: 'com.android.support', module: 'support-annotations'
    })
    compile 'com.android.support:appcompat-v7:26.+'
    compile 'com.android.support.constraint:constraint-layout:1.0.2'
    testCompile 'junit:junit:4.12'
    compile files('libs/slf4j-android-1.5.8.jar')
compile files('libs/osmdroid-android-3.0.8.jar')

}

但是当我运行应用程序时，我只能看到小矩形，而不是地图。 我该怎么解决这个问题？我应该遵循哪些步骤？

任何想法都表示赞赏？

替换

import com.exercise.OpenStreetMapView.R;

用这个：

import com.example.re.osm.R;
