Question

我没有找到解决这个荒谬问题的方法。 setRepeating（）和setInexactRepeating（）根本不会触发。我试过这两种方法。以下是我的代码：

Intent intentService = new Intent(context, ServiceReceiver.class);
intentService.putExtra("checkStrikeAndNews", true);
PendingIntent pendingIntentSN = PendingIntent.getBroadcast(context,   0,intentService, PendingIntent.FLAG_CANCEL_CURRENT);

AlarmManager alarmMgr = (AlarmManager)context.getSystemService(Context.ALARM_SERVICE);

//scheduling checkNews
alarmMgr.setRepeating(AlarmManager.RTC_WAKEUP, System.currentTimeMillis(), AlarmManager.INTERVAL_FIFTEEN_MINUTES, pendingIntentSN);

我也尝试过使用setInexactRepeating（），但它不起作用。我还使用了ELAPSED_REALTIME_WAKEUP和SystemClock.elapsedRealtime（），行为相同。

广播接收器ServiceReceiver.class完美地工作，它接收其他意图和警报意图（AlarmManager set（）和setExact（））没有问题。我在ICS，JellyBean和Marshmallow上测试了代码。

非常感谢！

我认为您必须使用PendingIntent.getService()代替PendingIntent.getBroadcast()
请确保您的服务已在Manifest.xml
最好使用setInexactRepeating()电池续航时间

App.class 我在哪里设置闹钟

public class App extends Application {

    private static final int INTERVAL = 1000 * 60;
    private static final int DELAY = 5000;

    @Override
    public void onCreate() {
        super.onCreate();
        setupAlarm();
    }

    private void setupAlarm() {
        PendingIntent myPendingIntent = PendingIntent.getService(this, 0, MyService.newIntent(this), 0);
        AlarmManager alarmMgr = (AlarmManager) getSystemService(Context.ALARM_SERVICE);
        alarmMgr.setInexactRepeating(AlarmManager.ELAPSED_REALTIME_WAKEUP, DELAY, INTERVAL, myPendingIntent);
    }
}

MyService.class 我管理收到的意图

public class MyService extends IntentService {

    private static final String TAG = MyService.class.getSimpleName();
    private static final String EXTRA_CHECK = "checkStrikeAndNews";

    /**
     * Creates an IntentService.  Invoked by your subclass's constructor.
     */
    public MyService() {
        super("MyService");
    }

    public static Intent newIntent(Context context) {
        return new Intent(context, MyService.class) //
                .putExtra(EXTRA_CHECK, true);
    }

    @Override
    protected void onHandleIntent(Intent intent) {
        if (intent.getBooleanExtra(EXTRA_CHECK, false)) {
            Log.i(TAG, "I just received an intent");
        }
    }
}

Manifest.xml 我在哪里宣布我的服务

<manifest
    package="com.darzul.test"
    xmlns:android="http://schemas.android.com/apk/res/android">

    <application
        android:allowBackup="true"
        android:icon="@mipmap/ic_launcher"
        android:label="@string/app_name"
        android:name=".App"
        android:theme="@style/AppTheme">

        <activity android:name=".activity.MainActivity">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>

        <service android:name=".service.MyService" />
    </application>

</manifest>

以下是包含BroadcastReceiver

<强> App.class

public class App extends Application {

    private static final int INTERVAL = 1000 * 60;
    private static final int DELAY = 5000;

    @Override
    public void onCreate() {
        super.onCreate();
        setupAlarm();
    }

    private void setupAlarm() {
        Intent myIntent = new Intent(this, MyReceiver.class);
        PendingIntent myPendingIntent = PendingIntent.getBroadcast(this, 0, myIntent, 0);
        AlarmManager alarmMgr = (AlarmManager) getSystemService(Context.ALARM_SERVICE);
        alarmMgr.setInexactRepeating(AlarmManager.ELAPSED_REALTIME_WAKEUP, DELAY, INTERVAL, myPendingIntent);
    }
}

警告：如果您在SDK等于或大于5.1的设备上进行测试，则间隔警报不能少于1分钟。

自Android 5.1起，价值将被强制为60000;不要依赖于这一点频繁的警报不利于电池寿命。从API 22开始，AlarmManager将覆盖近期和高频警报请求，将警报延迟至少5秒，并确保重复间隔至少为60秒。如果您确实需要在5秒钟之前完成工作，请发布延迟消息或运行至处理程序。

<强> MyReceiver.class

public class MyReceiver extends BroadcastReceiver {

    private static final String TAG = "MyReceiver";

    @Override
    public void onReceive(Context context, Intent intent) {
        Log.d(TAG, "onReceive");
    }
}

<强>的Manifest.xml

<manifest
    package="com.darzul.test"
    xmlns:android="http://schemas.android.com/apk/res/android">

    <application
        android:allowBackup="true"
        android:icon="@mipmap/ic_launcher"
        android:label="@string/app_name"
        android:name=".App"
        android:theme="@style/AppTheme">

        <activity android:name=".activity.MainActivity">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>

        <receiver
            android:exported="false"
            android:name=".receiver.MyReceiver" />
    </application>

</manifest>

Android setRepeating（）和setInexactRepeating（）不会触发
