在Android中使用Web服务

在Android中使用Web服务,android,performance,android-intent,Android,Performance,Android Intent,我正在学习如何在android应用程序中实现和使用Web服务。我能从所有使用网络服务的专业人士那里得到一些建议吗?我应该从哪里开始,使用Android应用程序时,哪种方法或类型的网络服务最可靠、最有效 提前谢谢。 阿里使用Ksoap有关更多详细信息,请参阅链接。 使用Ksoap了解更多详细信息,请参阅链接。 使用此链接 导入org.ksoap2.SoapEnvelope; 导入org.ksoap2.serialization.SoapObject; 导入org.ksoap2.serial
