我正在尝试从URL获取标记。我想要的是从this web service得到所有标记。
我的代码无效。它从Web服务获取map_icon但未在地图上显示。我能做些什么才能让它发挥作用？

NetworkOnMainThreadException当应用程序尝试在其主线程上执行网络操作时引发的异常。
在onPostExecute()中将您的Json解析代码移至doInBackground
现在在addMarkers()方法中使用picasso加载标记图像并使用位图。
private Target target = new Target() {
@Override
public void onBitmapLoaded(Bitmap bitmap, Picasso.LoadedFrom from) {
//here you get the image bitmap
//do your work
}
@Override
public void onBitmapFailed(Drawable errorDrawable) {
}
@Override
public void onPrepareLoad(Drawable placeHolderDrawable) {
}
}
使用：
来调用它 Picasso.with(this).load("your_url").into(target);
在gradle中添加：compile 'com.squareup.picasso:picasso:2.5.2'
