Android Google maps java.lang.NoClassDefFoundError： Failed resolution of： LorgapachehttpProtocolVersion

我正在使用Google maps Android SDK 11.6.2(也try 了15.0.1)，但在 map 显示之前我遇到了以下崩溃.已经判断了 list 中的API密钥，它是可用的，但仍然会出现此问题.我有targetSDk版本as 28.是它导致了这个问题.

java.lang.NoClassDefFoundError: Failed resolution of: Lorg/apache/http/ProtocolVersion;
