[英]Unable to start the intent after BOOT_COMPLETED
I have a problem regarding about re-scheduling the tasks (with alarm) I tried to set the task on exact time and date in the future then I closed the emulator then re-open it after that waiting to popup the layout and when the time and date is on due I got error which says unable to open the (app/activity) on the screen, also in the logcat I can't see the errors (which probably the app is closed), So I'm not sure where exactly I did something wrong.我有一个关于重新安排任务(带警报)的问题我试图在未来的确切时间和日期设置任务然后我关闭模拟器然后重新打开它之后等待弹出布局和时间日期是由于我收到错误,提示无法在屏幕上打开(应用程序/活动),也在 logcat 中我看不到错误(可能应用程序已关闭),所以我不确定在哪里正是我做错了什么。
Here is the code I used for the service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);
}
}
The OnBootReceiver 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
}
}

You need to explicitly call close
on your database connection which is missing, so add it either at the end of getListSched
function您需要在缺少的数据库连接上显式调用
close
,因此将其添加到getListSched
函数的末尾
List<DatabaseSource> getListSched(){
..
..// your code
yourSQLiteDatabaseObject.close();
}
or或者
if your yourSQLiteDatabaseObject
instance is public then you can do this before looping如果您的
yourSQLiteDatabaseObject
实例是公开的,那么您可以在循环之前执行此操作
List<DatabaseSource> tasks = db.getListSched();
db.yourSQLiteDatabaseObject.close();
for (DatabaseSource task : tasks) {
Note: yourSQLiteDatabaseObject
will be a object of SQLiteDatabase
inside your DatabaseSched
class or you need to look for the chain if it's not in DatabaseSched
class;注意:
yourSQLiteDatabaseObject
将是DatabaseSched
类中SQLiteDatabase
的对象,或者如果它不在DatabaseSched
类中,则需要查找链;
