我试图在我的Android应用程序中实现Google Maps v2,但遗憾的是,我收到了以下消息:

是否可以在Android模拟器(平台4.2)上运行这些地图?
android android-virtual-device android-emulator google-play-services android-maps-v2
我想将我的UIImage设置为WKInterfaceImage,但模拟器只显示黑屏.它可以正常使用 setImageNamed: NSString*方法,但不能使用setImage: UIImage*.我的file1.png被添加到"(App Name)WatchKit App"文件夹中.
- (void)willActivate {
[self.imageView1 setImage: [UIImage imageNamed: @"file1"]]; // doesn't work
[self.imageView1 setImageNamed: @"file1"]; // works OK
[super willActivate];
}
