【问题描述】：
我正在为我的项目使用原生地图 CN1Lib。我按照here 的说明添加了所需的构建提示。在模拟器中，地图看起来不错，但是当我将其导出到 android（在 android studio 上调试）时，地图仅显示为左下角带有“Google”的灰色矩形。
我认为这是关于 google api 的问题，所以我在 google 控制台上创建了一些新的 api 密钥。所有的键都没有限制。 Google Maps Android API 也已启用，但问题仍然存在。我还检查了在导出的 apk 的 AndroidManifest.xml 中是否包含正确的 api。
以下是构建提示（部分 api 密钥被审查）：
codename1.android.keystore=
codename1.android.keystoreAlias=
codename1.android.keystorePassword=
codename1.arg.android.playService.maps=true
codename1.arg.android.xapplication=<meta-data android\:name\="com.google.android.maps.v2.API_KEY" android\:value\="AIza__________________________________"/>
codename1.arg.build.incSources=1
codename1.arg.ios.add_libs=SystemConfiguration.framework
codename1.arg.ios.afterFinishLaunching=[GMSServices provideAPIKey\:@"AIza__________________________________"];
codename1.arg.ios.locationUsageDescription=To provide near-by stores info to the user
codename1.arg.ios.newStorageLocation=true
codename1.arg.ios.objC=true
codename1.arg.java.version=8
codename1.arg.javascript.googlemaps.key=AIza__________________________________
codename1.displayName=Medi
codename1.icon=icon.png
codename1.ios.certificate=
codename1.ios.certificatePassword=
codename1.ios.provision=
codename1.j2me.nativeTheme=nativej2me.res
codename1.languageLevel=5
codename1.mainName=Medi
codename1.packageName=com.my.medi
codename1.rim.certificatePassword=
codename1.rim.signtoolCsk=
codename1.rim.signtoolDb=
codename1.secondaryTitle=Medi
codename1.vendor=CodenameOne
codename1.version=1.0
libVersion=203
我不知道现在该怎么做。请指教。

我不确定“缺少的类加载器部分”是否相关。提前致谢

事实证明，这只是 Android Studio 显示 won't run unless you update the Google Play Service 错误的另一种方式，使用 API 版本 21 (Android 5.0) 可以解决该问题。需要进行设备测试
