Question

我正在尝试创建一个应用程序来接收带有特定内容的传入短信，并显示通知（带声音），即使手机处于睡眠模式。如果手机未处于睡眠模式，该应用程序正常工作。但是一旦手机处于睡眠状态，我会在手动唤醒手机后收到通知。我在清单文件中拥有必要的权限，并且我还实现了full_wake_lock函数。

这是我的清单文件：

    <?xml version="1.0" encoding="utf-8"?>
    <manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.androidexample.broadcastreceiver"
    android:versionCode="1"
    android:versionName="1.0" >

    <application
        android:allowBackup="true"
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name" android:debuggable="true"
        android:theme="@style/AppTheme" >
        <activity
            android:name=".BroadcastNewSms"
            android:label="@string/app_name" >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>

        <receiver android:name=".IncomingSms"
            android:permission="android.permission.BROADCAST_SMS">
            <intent-filter android:priority="2147483647" >
                <action android:name="android.provider.Telephony.SMS_RECEIVED" />
            </intent-filter>
        </receiver>

    </application>

    <uses-permission android:name="android.permission.INTERNET" />
    <uses-permission android:name="android.permission.RECEIVE_SMS" />
    <uses-permission android:name="android.permission.READ_SMS" />
    <uses-permission android:name="android.permission.WAKE_LOCK" />
    <uses-permission android:name="android.permission.DISABLE_KEYGUARD" />
    <uses-permission android:name="android.permission.SEND_SMS" />
    <uses-permission android:name="android.permission.VIBRATE" />

</manifest>

MainActivity：

    public class BroadcastNewSms extends Activity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        Log.i("LOG'", " - broadcast created");
        setContentView(R.layout.androidexample_broadcast_newsms);
        getWindow().addFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON);

    }
}

广播接收器：

    public class IncomingSms extends BroadcastReceiver {

    final SmsManager sms = SmsManager.getDefault();

    public void onReceive(Context context, Intent intent) {
        Log.i("LOG'"," - onreceive called");
        WakeLocker.acquire(context);

        final Bundle bundle = intent.getExtras();
        try {
            if (bundle != null) {

                final Object[] pdusObj = (Object[]) bundle.get("pdus");

                for (int i = 0; i < pdusObj.length; i++) {

                    SmsMessage currentMessage = SmsMessage.createFromPdu((byte[]) pdusObj[i]);
                    String phoneNumber = currentMessage.getDisplayOriginatingAddress();

                    String senderNum = phoneNumber;
                    String message = currentMessage.getDisplayMessageBody();
                    if (message.equals("test")) {

                        Log.i("SmsReceiver", "senderNum: " + senderNum + "; message: " + message);

                        AudioManager audioManager = (AudioManager) context.getSystemService(Context.AUDIO_SERVICE);
                        int maxVolume = audioManager.getStreamMaxVolume(AudioManager.STREAM_RING);
                        audioManager.setRingerMode(AudioManager.RINGER_MODE_NORMAL);
                        audioManager.setStreamVolume(AudioManager.STREAM_RING, maxVolume, AudioManager.FLAG_SHOW_UI + AudioManager.FLAG_PLAY_SOUND);

                        int duration = Toast.LENGTH_LONG;
                        Toast toast = Toast.makeText(context, "Sender: "+ senderNum + ", Message: " + message, duration);
                        toast.show();

                        final int NOTIF_ID = 1234;
                        NotificationManager notifManager = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
                        Notification note = new Notification(R.drawable.ic_launcher, "New sms", System.currentTimeMillis());
                        PendingIntent intent2 = PendingIntent.getActivity(context, 0, new Intent(context, IncomingSms.class), 0);
                        note.setLatestEventInfo(context, "New sms", "You have one unread message.", intent2);
                        notifManager.notify(NOTIF_ID, note);
                        Log.i("LOG'"," - notified");
                        // notifManager.cancel(NOTIF_ID);
                        WakeLocker.release();
                        //abortBroadcast();
                    }
                }
              }

        } catch (Exception e) {
            Log.e("SmsReceive", "Exception" +e);

        }

    }

}

WakeLocker：

    public abstract class WakeLocker {
    private static PowerManager.WakeLock wakeLock;

    public static void acquire(Context ctx) {
        if (wakeLock != null) wakeLock.release();

        PowerManager pm = (PowerManager) ctx.getSystemService(Context.POWER_SERVICE);
        wakeLock = pm.newWakeLock(PowerManager.FULL_WAKE_LOCK |
                PowerManager.ACQUIRE_CAUSES_WAKEUP |
                PowerManager.ON_AFTER_RELEASE, "mysms1");
        wakeLock.acquire();
    }

    public static void release() {
        if (wakeLock != null) wakeLock.release(); wakeLock = null;
    }
}

我真的不知道会出现什么问题，但我花了3天才找到它...... 我会感激任何帮助！

问题在于模拟器本身。即使rtc_wakeup功能也无效。我在真实的设备上试过我的应用程序并且工作正常......
