我上面附上了我的代码。它只是OSMDroid的一个简单实现，在两个地方显示了启动器图标。但我的应用程序不播放任何地图。它只显示网格（地图网格，而不是实际位置）。

此程序清单文件添加如下：

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.andersoncouncil.osm_01"
    android:versionCode="1"
    android:versionName="1.0" >

    <uses-sdk
        android:minSdkVersion="8"
        android:targetSdkVersion="15" />

            </intent-filter>
        </activity>
    </application>

</manifest>

在这里的任何人，谁知道问题或可以检测到它，请回复。

什么版本的osmdroid？你的目标api是什么？如果您使用API 23及更高版本作为目标，则您已明确要求用户获得Internet访问和文件系统存储的许可。最新的osmdroid示例应用程序有一个例子，说明了所需的内容。 Android文档也有一个很好的例子。

OSMDroid地图没有显示 - 只有小灰色瓷砖
