手机重启时的错误通知？它有最新通知的时间权限，但文本是数据库中的第一个结果
手机重启时的错误通知？它有最新通知的时间权限，但文本是数据库中的第一个结果
提问于 2018-02-05 10:41:57
我有一个广播接收器。其中我试图在重启后重置警报。我使用IntentServices来setAlarms和创建通知。我使用游标来检索闹钟定时和描述的值，并在广播接收器的onReceive中对其进行重置。我必须使用循环来重置所有警报。但是IntentService设置了警报，但显示了错误的通知。我检查了日志，它有错误的数据。我会把代码贴出来。请给我建议。图片如下所示。Stack Trace 1Stack trace 2 Notification on phone

修好了。下面是我所做的更改。它在IntentService类中。在PendingIntent中添加了一个标志。PendingIntent.FLAG_CANCEL_CURRENT。
static PendingIntent getReminderPendingIntent(Context context, ContentValues contentValues){
Intent intent=new Intent(context, ReminderAlarmService.class);
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
intent.putExtra(CONTENTVALUES,contentValues);
Log.i(TAG,"Description: "+contentValues.getAsString(DatabaseContract.columns.description));
PendingIntent pendingIntent=PendingIntent.getService(context,0,intent,PendingIntent.FLAG_CANCEL_CURRENT);
//
//context.startService(intent);
return pendingIntent;
