Osmdroid 5.1 java.lang.NoClassDefFoundError
Osmdroid 5.1 java.lang.NoClassDefFoundError
我什至无法创建简单的地图。我正在使用 osmdroid-android-5.1 库，据我了解，我不需要从 5.0 及更高版本添加 slf4j 库。
我的activity_main.xml如下：
<include
layout="@layout/app_bar_main"
android:layout_width="match_parent"
android:layout_height="match_parent" />
<android.support.design.widget.NavigationView
android:id="@+id/nav_view"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_gravity="start"
android:fitsSystemWindows="true"
app:headerLayout="@layout/nav_header_main"
app:menu="@menu/activity_main_drawer" />
和 content_main.xml 包含如下地图：
<org.osmdroid.views.MapView android:id="@+id/map"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
tilesource="Mapnik" />
我的AndroidManifest.xml如下：
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"/>
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/>
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<application
android:allowBackup="true"
android:icon="@mipmap/ic_launcher"
android:label="@string/app_name"
android:supportsRtl="true"
android:theme="@style/AppTheme">
<activity
android:name=".MainActivity"
android:label="@string/app_name"
android:theme="@style/AppTheme.NoActionBar">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
当我点击 activity_main 预览时，出现错误：

知道错误可能在哪里并且无法实现如此简单的事情（除非我没有看到任何明显的东西）吗？
osmdroid 不提供 intellij 试图呈现的 "preview"。常量 class 正在尝试扫描本地存储以用作下载缓存。它可能可以更好地处理。
无论如何，要解决您的问题，只需点击播放按钮并 运行 应用程序。它应该在 android 设备或模拟器
上正常工作
