嘿,当我将我的应用程序安装到模拟器时,我得到了这个:
错误/AndroidRuntime(465):java.lang.RuntimeException:无法启动接收器 com.myPackage.Widget.MYWidget:java.lang.SecurityException:不允许启动服务 Intent { cmp=com.myPackage/.Widget.MYWidget$MyWidgetService } 未经许可 android.permission.BIND_REMOTEVIEWS
这是我清单中的代码
<!-- Broadcast Receiver that will process AppWidget updates -->
<receiver android:name=".Widget.MYWidget" android:label="@string/app_name">
<intent-filter>
<action android:name="android.appwidget.action.APPWIDGET_UPDATE" />
