应用关闭时,Android推送通知无法正常工作

问题描述 投票:2回答:2

我正在使用OkSse订阅我的服务器发送事件。

每当服务器发送新消息时,无论应用程序处于前台,最小化还是完全关闭,都应显示通知。

当最小化或在前台时,通知按预期工作,但在完全关闭时,这仅适用于某些设备品牌。

研究bit,我发现:

这个问题仅在小米,Oppo,One Plus,Vivo,联想,华为,三星等公司的手机上引起注意。

即使应用关闭,WhatsApp, Facebook, Slack, Gmail, etc..如何显示通知?

我不使用FCM,只订阅Sse

我也有清单:

<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />

<receiver android:name="com.goparty.communication.NotificationsAlarmReceiver">
    <intent-filter>
        <action android:name="android.media.action.DISPLAY_NOTIFICATION" />
        <action android:name="android.intent.action.BOOT_COMPLETED"/>
    </intent-filter>
</receiver>

我怎样才能做到这一点?

更新

我设法通过使用IntentServiceBroadcastReceiver使其工作,但这崩溃的Oreo版本。

在更多reading之后,我发现当针对JobIntentService及以上时,IntentServiceAndroid O的替代品。

过渡到JobIntentService非常简单,但同样,当我关闭应用程序时,我的解决方案无效。

即使应用程序关闭,通知的整个目的也是可行的。

使用IntentService在后台工作,发送一个broadcast与我的服务的新意图。

我和JobIntentService一样没有运气。

这是我的代码:

public class NotificationService extends JobIntentService {

    private static final int JOB_ID = 1;
    private NotificationManager notificationManager;

    public static void enqueueWork(Context context, Intent intent) {
        enqueueWork(context, NotificationService.class, JOB_ID, intent);
    }

    @Override
    public void onCreate() {
        super.onCreate();
        Logger.logGoParty(getClass().getSimpleName() + "#onCreate");
        notificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
    }

    @Override
    public void onDestroy() {
        super.onDestroy();
        Logger.logGoParty("Running in background.");
        sendBroadcast(new Intent(getApplicationContext(), NotificationService.class));
    }

    @Override
    protected void onHandleWork(@NonNull Intent intent) {
        Logger.logGoParty(getClass().getSimpleName() + "#onHandleWork");
        Logger.logGoParty("Sse initialized");

        Request request = new Request.Builder().url("the sse url").build();
        OkSse okSse = new OkSse();

        ServerSentEvent sse = okSse.newServerSentEvent(request, new ServerSentEvent.Listener() {
            @Override
            public void onOpen(ServerSentEvent sse, Response response) {
                Logger.logGoParty(response.toString());
            }

            @Override
            public void onMessage(ServerSentEvent sse, String id, String event, String message) {
                Logger.logGoParty("Sse#onMessage: " + message);
                try {
                    JSONObject promoJson = new JSONObject(message);

                    sendNotification(...);

                } catch (JSONException e) {
                    Logger.logGoParty("JSONException: " + e.toString());
                }
            }
                // ...
        });
    }

    private void sendNotification(String promoImageUrl, String notificationContent, String title) {

        try {
            URL url = new URL(promoImageUrl);
            Bitmap bitmap = BitmapFactory.decodeStream(url.openConnection().getInputStream());


            NotificationCompat.BigPictureStyle style = new NotificationCompat.BigPictureStyle();
            style.bigPicture(bitmap);

            Uri defaultSound = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);

            Intent intent = new Intent(this, MapsActivity.class);
            intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_SINGLE_TOP);
            intent.putExtra("page-to-open", "promotions");
            PendingIntent pendingIntent = PendingIntent.getActivity(this, 0, intent, 0);


            NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this, GoParty.PROMO_CHANNEL_ID)
                    .setSmallIcon(R.mipmap.ic_launcher_round)
                    .setContentTitle(title)
                    .setAutoCancel(true)
                    .setSound(defaultSound)
                    .setContentText(notificationContent)
                    .setContentIntent(pendingIntent)
                    .setStyle(style)
                    .setLargeIcon(bitmap)
                    .setWhen(System.currentTimeMillis())
                    .setPriority(NotificationCompat.PRIORITY_HIGH)
                    .setCategory(NotificationCompat.CATEGORY_MESSAGE);

            notificationManager.notify(0, notificationBuilder.build());

            Log.i("GoParty", "Notification sent ----- ");

        } catch (MalformedURLException e) {
            Logger.logGoParty(e.toString());
        } catch (IOException e) {
            Logger.logGoParty(e.toString());
        }
    }
}

通知接收者:

public class NotificationReceiver extends BroadcastReceiver {

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

        Intent notificationIntent = new Intent(context, NotificationService.class);
        NotificationService.enqueueWork(context, notificationIntent);
    }

这背后的主要原因是AutoLaunch和电池优化(MIUI)设备在电池设置中尝试更改您的应用的优化选项

 private void initOPPO() {
        try {

            Intent i = new Intent(Intent.ACTION_MAIN);
            i.setComponent(new ComponentName("com.oppo.safe", "com.oppo.safe.permission.floatwindow.FloatWindowListActivity"));
            startActivity(i);
        } catch (Exception e) {
            e.printStackTrace();
            try {

                Intent intent = new Intent("action.coloros.safecenter.FloatWindowListActivity");
                intent.setComponent(new ComponentName("com.coloros.safecenter", "com.coloros.safecenter.permission.floatwindow.FloatWindowListActivity"));
                startActivity(intent);
            } catch (Exception ee) {

                ee.printStackTrace();
                try {

                    Intent i = new Intent("com.coloros.safecenter");
                    i.setComponent(new ComponentName("com.coloros.safecenter", "com.coloros.safecenter.sysfloatwindow.FloatWindowListActivity"));
                    startActivity(i);
                } catch (Exception e1) {

                    e1.printStackTrace();
                }
            }

        }
    }

    private static void autoLaunchVivo(Context context) {
        try {
            Intent intent = new Intent();
            intent.setComponent(new ComponentName("com.iqoo.secure",
                    "com.iqoo.secure.ui.phoneoptimize.AddWhiteListActivity"));
            context.startActivity(intent);
        } catch (Exception e) {
            try {
                Intent intent = new Intent();
                intent.setComponent(new ComponentName("com.vivo.permissionmanager",
                        "com.vivo.permissionmanager.activity.BgStartUpManagerActivity"));
                context.startActivity(intent);
            } catch (Exception ex) {
                try {
                    Intent intent = new Intent();
                    intent.setClassName("com.iqoo.secure",
                            "com.iqoo.secure.ui.phoneoptimize.BgStartUpManager");
                    context.startActivity(intent);
                } catch (Exception exx) {
                    ex.printStackTrace();
                }
            }
        }
    }

用法

if (Build.MANUFACTURER.equalsIgnoreCase("oppo")) {
                                initOPPO();
                            } else if (Build.MANUFACTURER.equalsIgnoreCase("vivo")) {
                                autoLaunchVivo(BaseSettingActivity.this);
                            } else if (Build.MANUFACTURER.equalsIgnoreCase("xiaomi")) {
                                try {
                                    Intent intent = new Intent();
                                    intent.setComponent(new ComponentName("com.miui.securitycenter", "com.miui.permcenter.autostart.AutoStartManagementActivity"));
                                    startActivity(intent);
                                } catch (Exception e) {
                                    e.printStackTrace();
                                }
                            }

您的方法:使用OkSse进行通知意味着需要运行后台服务。

问题1:Android后台服务限制link

JobIntentService内部将使用JobService,它不会是一个继续运行的服务。它不会无差别地运行,因为执行时间限制将适用。它将停止并重新安排,以便稍后继续执行。所以在你的情况下,它将无法正常工作。

问题2:设备小米,Oppo,One Plus,Vivo,联想,华为,三星都有电池优化检查,让JobIntentService停止。

解:

1)运行前台服务,这是丑陋的,不推荐

2)Firebase高优先级通知link强烈推荐

我已经在上面提到的设备上实现了它,即使应用程序设置为电池优化模式,您也会收到通知。
