请在应用程序启动时添加代码段。我一开始就启动了远程服务。每次catlog被这个错误填满时，你都不是认真的。此日志与Web服务有什么关系？您应该发布引发这些错误消息的代码。谢谢greenapps，此错误不仅适用于应用程序，它还会在应用程序停止和卸载后持续显示。我换了2个手机1个。intex水速2。联想。。。两者都有相同的问题请删除不相关的日志。然后解释什么不起作用。发布应用程序仅生成的错误日志。请在应用程序启动时添加代码段。我一开始就启动了远程服务。每次catlog被这个错误填满时，你都不是认真的。此日志与Web服务有什么关系？您应该发布引发这些错误消息的代码。谢谢greenapps，此错误不仅适用于应用程序，它还会在应用程序停止和卸载后持续显示。我换了2个手机1个。intex水速2。联想。。。两者都有相同的问题请删除不相关的日志。然后解释什么不起作用。发布应用程序仅生成的错误日志。
