我已经研究了一段时间了，但我遇到了一个我无法弄清楚的错误。我的小部件开始正常并正在更新（我遇到了画布引发回收位图错误的问题）所以我清理了我的项目，现在它无法运行。日志是：

接收者应该喜欢：--

         <receiver
          android:name="com.msg2email.automatic.AutomaticMode"
           android:process=":remote" />

com.msg2email.automatic 是Package& AutomaticMode.JavaClass

请android:enable="true"在接收器标签中制作manifest.xml
