java - BOOT_COMPLETED后无法启动意图

我有一个关于重新计划任务（带有警报）的问题，我试图在将来的确切时间和日期上设置任务，然后关闭模拟器，然后在等待弹出布局和时间后重新打开它由于日期错误，提示我无法打开屏幕上的（应用程序/活动），而且在logcat中也看不到错误（可能是应用程序已关闭），所以我不确定在哪里我确实做错了什么。

这是我用于服务的代码

public class ChibiReminderService extends WakefulIntentService {
 Date date;
 private long milliseconds = 0;
 public ChibiReminderService() {
        super("ChibiReminderService");`
    }

    @Override
    protected void onHandleIntent(Intent intent) {
        DatabaseSched db = DatabaseSched.getInstance(this); //get access to the instance of DatabaseSched
        sched_lists alarm = new sched_lists();

        List<DatabaseSource> tasks = db.getListSched(); //Get a list of all the tasks there
        for (DatabaseSource task : tasks) {
            // Cancel existing alarm
            alarm.cancelAlarm(this, task.getId());
            SimpleDateFormat format = new SimpleDateFormat("yyyy-MM-dd hh:mm a");

             try {
                  date = format.parse(task.getDueDateTime());
                 milliseconds = date.getTime();
             } catch (Exception e) {
                 e.printStackTrace();
             }

            //regular alarms
            if(milliseconds >= System.currentTimeMillis()){
                alarm.setAlarm(this, task.getId());
            }
        }
        super.onHandleIntent(intent);
    }
}

OnBootReceiver

public class OnBootReceiver extends BroadcastReceiver {

 @Override
 public void onReceive(Context context, Intent intent) {
    // TODO Auto-generated method stub
    WakefulIntentService.acquireStaticLock(context); //acquire a partial WakeLock
    context.startService(new Intent(context, ChibiReminderService.class)); //start ChibiReminderService
 }

}

表现

  <manifest xmlns:android="http://schemas.android.com/apk/res/android"

最佳答案

您需要在缺少的数据库连接上显式调用close，因此请在getListSched函数的末尾添加它

List<DatabaseSource> getListSched(){
..
..// your code
     yourSQLiteDatabaseObject.close();
}

要么

如果您的yourSQLiteDatabaseObject实例是公共实例，则可以在循环之前执行此操作

 List<DatabaseSource> tasks = db.getListSched();
 db.yourSQLiteDatabaseObject.close();
        for (DatabaseSource task : tasks) {

注意：yourSQLiteDatabaseObject将是SQLiteDatabase类中DatabaseSched的对象，或者如果它不在DatabaseSched类中，则需要查找链。
