【问题描述】:
我正在尝试让我的广播接收器在启动后立即运行。据我所知,无论重新启动广播接收器都会运行,我刚刚了解到,但我的问题是我已将其设置为每晚午夜运行,我不想等到午夜运行一次这违背了目的。但是我需要它在重新启动一次后立即运行。但它没有运行。有人可以看看我做错了什么吗?我正在 Galaxy S4 和 S6 上尝试此操作,但未收到说明已重新启动的日志消息。
这是我的 Manifest 文件,你可以看到它是必要的权限。
<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />
<receiver
android:name=".StartActivityAtBootReceiver"
android:enabled="true" >
<intent-filter>
<action android:name="android.intent.action.BOOT_COMPLETED" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
</receiver>
在我的 StartActivityAtBootReceiver 中,我有 onReceive 调用将启动广播接收器的主要活动。
public void onReceive(Context context, Intent intent) {
Log.e("LOGS", "Start Activity after Rebooted ");
Intent rebootIntent = new Intent(context, MainActivity.class);
rebootIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
context.startActivity(rebootIntent);
}
在我的 MainActivity 中,我有以下调用广播接收器的另一个类中的广播接收器,该类扩展了广播接收器。
//run from boot or from button on screen
protected void runFromOutside() throws ParseException {
checkIfStartingNow();
startTheClock();
finish(); //close the app/view
}
//check if starting now pops up message to state that it is staring now
protected void checkIfStartingNow() throws ParseException {
//does some checks and displays a message popup
}
protected void startTheClock() {
// Set the alarm to run at midnight every night
Calendar calendar = Calendar.getInstance();
calendar.setTimeInMillis(System.currentTimeMillis());
calendar.set(Calendar.HOUR_OF_DAY, 00);
//calendar.set(Calendar.MINUTE, 01);
// Get the AlarmManager Service
mAlarmManager = (AlarmManager) getSystemService(ALARM_SERVICE);
// Create an Intent to broadcast to the Shhh
mNotificationReceiverIntent = new Intent(MainActivity.this, Shhh.class);
// Create an PendingIntent that holds the NotificationReceiverIntent
// mNotificationReceiverPendingIntent = PendingIntent.getBroadcast(MainActivity.this, 0, mNotificationReceiverIntent, PendingIntent.FLAG_UPDATE_CURRENT);
mNotificationReceiverPendingIntent = PendingIntent.getBroadcast(MainActivity.this, 0, mNotificationReceiverIntent, PendingIntent.FLAG_UPDATE_CURRENT);
//Set repeating alarm that checks every minute.
mAlarmManager.setInexactRepeating(AlarmManager.RTC, calendar.getTimeInMillis(), AlarmManager.INTERVAL_DAY, mNotificationReceiverPendingIntent);
// set true for alarm
settings.edit().putBoolean(NotificationOn, true).apply();
Log.e("LOGS", "Entered Start the midnight alarm");
}
