Question

这是代码

此函数从MainActivity.onCreate（）

调用

 private void setTheTimeToUpdateTables(Context context) {

        Log.i("Update table function","Yes");

        AlarmManager alarmManager=(AlarmManager) getSystemService(ALARM_SERVICE);

        Intent alarmIntent=new Intent(context,UpdateTables.class);

        PendingIntent pendingIntent=PendingIntent.getBroadcast(context,0,alarmIntent,PendingIntent.FLAG_UPDATE_CURRENT);

        alarmManager.cancel(pendingIntent);


        Calendar alarmStartTime = Calendar.getInstance();

        alarmStartTime.set(Calendar.HOUR_OF_DAY, 0);
        alarmStartTime.set(Calendar.MINUTE, 00);
        alarmStartTime.set(Calendar.SECOND, 0);

        alarmManager.set(AlarmManager.RTC_WAKEUP,alarmStartTime.getTimeInMillis(),pendingIntent);

        Log.d("Alarm","Set for midnight");

    }

以下是updateTables的代码

public class UpdateTables extends BroadcastReceiver {

    @Override
    public void onReceive(Context context, Intent intent) {

        Log.i("Service Start", CalculateDaysService.TAG);
        Log.d("BroadCast Receiver","yes");

        context.startService(new Intent(context,CalculateDaysService.class));

        Log.i("Done","Yes");
    }
}

的Manifest.xml

 <receiver android:name=".UpdateTables" android:enabled="true"/>

无法调用updateTable类。

更新

private void setTheTimeToUpdateTables（Context context）{

    Log.i("Update table function","Yes");

    AlarmManager alarmManager=(AlarmManager) getSystemService(ALARM_SERVICE);

    Intent alarmIntent=new Intent(context,UpdateTables.class);

    PendingIntent pendingIntent=PendingIntent.getBroadcast(context,0,alarmIntent,PendingIntent.FLAG_UPDATE_CURRENT);

    alarmManager.cancel(pendingIntent);


    Calendar alarmStartTime = Calendar.getInstance();

    alarmStartTime.set(Calendar.HOUR_OF_DAY, 10);
    alarmStartTime.set(Calendar.MINUTE, 29);
    alarmStartTime.set(Calendar.SECOND, 0);

    if (alarmStartTime.get(Calendar.HOUR_OF_DAY) >= 10) {
        alarmStartTime.add(Calendar.DATE, 1);
    }

    alarmManager.setInexactRepeating(AlarmManager.RTC_WAKEUP,alarmStartTime.getTimeInMillis(),100*1000,pendingIntent);

    Log.d("Alarm","Set for midnight");

}


 <receiver android:name=".UpdateTables"
            android:enabled="true"
            android:exported="true">

            <intent-filter>
                <action android:name="android.intent.action.BOOT_COMPLETED" />
            </intent-filter>

        </receiver>

Answer 1

更改

alarmManager.set(AlarmManager.RTC_WAKEUP,alarmStartTime.getTimeInMillis(),pendingIntent);

要

alarmManager.setRepeating(AlarmManager.RTC_WAKEUP,alarmStartTime.getTimeInMillis(),pendingIntent);

或

alarmManager.setInexactRepeating(AlarmManager.RTC_WAKEUP,alarmStartTime.getTimeInMillis(),pendingIntent);

对于广播接收器，您已配置 AndroidManifest.xml

设置

android:exported = true

<强>的AndroidManifest.xml

在<manifest>标记
中
<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />
您的<application>代码
中的

<receiver android:name="com.yourpackage.UpdateTables"> <intent-filter> <action android:name="android.intent.action.BOOT_COMPLETED" /> </intent-filter> </receiver>
