Android上的Skobbler地图显示黑屏

Question

我正在使用Skobbler SDK 2.3.0,针对Lollipop,在基于Android Studio 1.0.2构建的Nexus 5和Galaxy S4上进行测试.

我有一个带有导航抽屉和片段的MainActivity.我在MainActivity中初始化Skobbler并加载显示地图的片段.但是,我只得到一个黑屏,右下角有"Powered by Scout OSM"的水印.已注册单击和双击,但如果我捏缩放应用程序崩溃.

在应用程序崩溃之前,我没有在logcat中看到任何错误.有人可以帮忙吗？

项目结构:

• 应用程序/库/ SKMaps.jar
• 应用程序/ src目录/主/资产/ SKMaps.zip
• 应用程序/ SRC /主/ jniLibs/armeabi/libngnative.so
• 应用程序/ SRC /主/ jniLibs/armeabi-V7A/libngnative.so
• 应用程序/ SRC /主/ jniLibs/86/libngnative.so

build.grade:

dependencies {
...
...
compile files('libs/SKMaps.jar')
}

logcat的

Answer 1

初始化地图后,您缺少一条语句:

mapView.onResume();

如果您查看Skobbler中的示例,您会看到它们将纹理复制到一个Activity并以不同的方式显示地图.该Activity可显示地图调用mapView.onResume()和mapView.onPause()在Activity回调.如果要加载纹理并显示相同的地图,则Activity必须mapView.onResume()在复制资源并初始化地图后调用.
