Android 未调用AlarmReceiver

Android 未调用AlarmReceiver,android,Android,我已经制作了一个android应用程序，我希望每天在特定的时间获得本地通知。我使用AlarmManager和BroadcastReceiver来执行此操作。但问题是没有调用扩展BroadCastReceiver的AlarmReceiver类。我知道这在stackoverflow中是一个重复的问题。我已经看完了所有的答案，尝试了所有的方法，但仍然无法解决问题这是我的主要活动 package com.dileepmanuballa224.alarm_test; import android.ap

我已经制作了一个android应用程序，我希望每天在特定的时间获得本地通知。我使用AlarmManager和BroadcastReceiver来执行此操作。但问题是没有调用扩展BroadCastReceiver的AlarmReceiver类。我知道这在stackoverflow中是一个重复的问题。我已经看完了所有的答案，尝试了所有的方法，但仍然无法解决问题

这是我的主要活动

package com.dileepmanuballa224.alarm_test;

import android.app.AlarmManager;
import android.app.PendingIntent;
import android.content.Context;
import android.content.Intent;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;

import java.util.Calendar;

public class MainActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
                Calendar calendar=Calendar.getInstance();
                calendar.set(Calendar.HOUR,9);
                AlarmManager alarmManager=(AlarmManager)getSystemService(Context.ALARM_SERVICE);
                Intent intent=new Intent(getApplicationContext(),AlarmReceiver.class);
                PendingIntent pendingIntent=PendingIntent.getActivity(getApplicationContext(),1,intent,0);
                alarmManager.setRepeating(AlarmManager.RTC_WAKEUP,calendar.getTimeInMillis(),AlarmManager.INTERVAL_DAY,pendingIntent);

    }
}

我的AlarmReceiverClass

import android.widget.Toast;


public class AlarmReceiver extends BroadcastReceiver {
    private static final String TAG = "alarm_test_check";

    @Override
    public void onReceive(Context context, Intent intent) {
        Toast.makeText(context,"AlarmReceiver called",Toast.LENGTH_SHORT).show();
        Log.d(TAG, "onReceive: called ");

我正在Android“牛轧糖”上测试此应用程序。

您必须更改日历的设置时间并添加此项，因此它将在每天上午9:00调用

AlarmReceiver

Calendar calendar=Calendar.getInstance();
calendar.add(Calendar.HOUR_OF_DAY, (24+9)-(cal.get(Calendar.HOUR_OF_DAY))); // <-- changes this
AlarmManager alarmManager=(AlarmManager)getSystemService(Context.ALARM_SERVICE);
Intent intent=new Intent(getApplicationContext(),AlarmReceiver.class);
PendingIntent pendingIntent=PendingIntent.getActivity(getApplicationContext(),1,intent,0);
alarmManager.setRepeating(AlarmManager.RTC_WAKEUP,calendar.getTimeInMillis(),AlarmManager.INTERVAL_DAY,pendingIntent);

Calendar Calendar=Calendar.getInstance（）；
calendar.add（calendar.HOUR OF_DAY，（24+9）-（calendar.get（calendar.HOUR OF_DAY））；// 如文件所述，也可以这样做
// Set the alarm to start at approximately 2:00 p.m.
Calendar calendar = Calendar.getInstance();
calendar.setTimeInMillis(System.currentTimeMillis());
calendar.set(Calendar.HOUR_OF_DAY, 14);

// With setInexactRepeating(), you have to use one of the AlarmManager interval
// constants--in this case, AlarmManager.INTERVAL_DAY.
alarmMgr.setInexactRepeating(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(),
        AlarmManager.INTERVAL_DAY, alarmIntent);

这将唤醒设备，在下午2:00左右触发警报，并每天在同一时间重复一次

要在API 23及更高版本中发出警报，您必须绕过瞌睡。要重复该警报，请使用BroadcastReceiver的onReceive（）
将第二天的警报设置为9，与添加此警报的方式相同。检查下面的示例代码（取自此代码）以绕过M及以上的doze
AlarmManager am;

Calendar calendar = Calendar.getInstance();

    calendar.add(Calendar.DAY_OF_MONTH, 1);

    calendar.set(Calendar.HOUR_OF_DAY, 9);
    calendar.set(Calendar.MINUTE, 0);
    calendar.set(Calendar.SECOND, 0);
    calendar.set(Calendar.MILLISECOND, 0);

    // Check if current time is smaller than cal time
    // otherwise notifications will come same day.
    if (System.currentTimeMillis() <= calendar.getTimeInMillis()) {

        SyncAlarm(context, calendar.getTimeInMillis());
    }


private void syncAlarm(Context context, long time) {
Intent intent = new Intent(this, YourBroadcastReceiver.class);

PendingIntent pendingIntent = PendingIntent.getBroadcast(context, 0, intent, 0);

if (Build.VERSION.SDK_INT >= 23) {
    // Wakes up the device in Doze Mode
    am.setExactAndAllowWhileIdle(AlarmManager.RTC_WAKEUP, time, // time in millis
    pending);
    } else if (Build.VERSION.SDK_INT >= 19) {
    // Wakes up the device in Idle Mode
    am.setExact(AlarmManager.RTC_WAKEUP, time, pending);
    } else {
    // Old APIs
    am.set(AlarmManager.RTC_WAKEUP, time, pending);
    } 
}

AlarmManager am；
日历=Calendar.getInstance（）；
calendar.add（calendar.DAY/u/u月，1）；
calendar.set（calendar.HOUR\u OF_DAY，9）；
calendar.set（calendar.MINUTE，0）；
calendar.set（calendar.SECOND，0）；
calendar.set（calendar.毫秒，0）；
//检查当前时间是否小于校准时间
//否则，通知将在当天发出。
if（System.currentTimeMillis（）=23）{
//在打瞌睡模式下唤醒设备
am.setExactAndAllowHileIDLE（AlarmManager.RTC_WAKEUP，time，//以毫秒为单位的时间
待定）；
}else if（Build.VERSION.SDK_INT>=19）{
//在空闲模式下唤醒设备
am.setExact（AlarmManager.RTC_唤醒，时间，待定）；
}否则{
//旧API
am.set（AlarmManager.RTC_唤醒、时间、挂起）；
} 
}
我找到了问题的根本原因，并发布了另一个问题。如果你想检查这个问题，你可以从

Android studio自动建议了错误的权限字符串。它建议使用“android.permission.SET_ALARM”，但应该是“com.android.ALARM.permission.SET_ALARM”。现在一切正常
 谢谢你们的快速反应，伙计们。我试过下面所有的答案。但仍然面临同样的问题。
