无法为android通知设置铃声

无法为android通知设置铃声,android,notifications,Android,Notifications,我正在开发一个需要为通知设置铃声的应用程序,因为我正在使用铃声选择器,它会在选择器上显示铃声列表,我可以选择铃声,但在下次设置铃声时,铃声选择器不会显示以前选择的铃声,并且通知会附带默认铃声。我陷入困境,找不到任何解决办法。提前谢谢 这是我的密码 public class ActivitySettings extends Activity { Context mContext; // making TypeFace object global for setting custom

在logcat中我得到了这个错误,但在Google上我找不到任何解决方案

我还没有看过你的代码,但我的第一个猜测是logcat的输出,它几乎准确地告诉你出了什么问题。您缺少所需的权限:

...this requires android.permission.INTERACT_ACROSS_USERS_FULL

编辑:好的,我检查了权限,这很糟糕。您将无法使用此权限,因为它是签名级别的权限。您在代码中使用的某些东西对普通开发人员来说是有限的。

您可能已经解决了这个问题,但对于任何感兴趣的人来说,我也遇到了同样的问题(这在三星设备上似乎更常见),我发现的解决方案是授予读取外部存储权限


附带说明:只有当您的应用程序是本机应用程序时,才能在用户之间进行完整的交互。否则,我已将此权限添加到我的应用程序manifest.xml中,但它不起作用。是的,我已经注意到并编辑了我的答案,请发布更多您的logcat输出。您还可以发布更多吗?我需要查看权限问题的具体位置,为此,我需要查看SecurityException前后的大量logcat输出。
