问题描述

I've got an Android app with push notifications set up using Urban Airship. The notifications work fine while my app is open but I need to still receive notifications when my app is closed. I've looked around but haven't found something that works. I'm pretty sure the problem is in my manifest, so here it is.

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="za.co.foo.android.financials"
    android:versionCode="1"

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

    <!-- Permissions for Urban Airship -->
    <uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED"/> <!-- Not sure if required for C2DM -->
    <uses-permission android:name="android.permission.VIBRATE"/>
    <uses-permission android:name="android.permission.BROADCAST_STICKY" />

    <!-- Only this application can receive the messages and registration result -->
    <permission android:name="za.co.foo.android.financials.permission.C2D_MESSAGE" android:protectionLevel="signature" />

    <application

        android:label="@string/app_name" >
        <activity
            android:name=".InvestorRelations"
            android:label="@string/app_name" 
            android:screenOrientation="landscape" 
            android:theme="@android:style/Theme.Holo.NoActionBar">

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

        <!-- For Urban Airship -->
        <receiver android:name="com.urbanairship.CoreReceiver">
        </receiver>

        <receiver android:name="com.urbanairship.push.c2dm.C2DMPushReceiver"
                android:permission="com.google.android.c2dm.permission.SEND"
                android:enabled="true">
             <!-- Receive the actual message -->
             <intent-filter>
                 <action android:name="com.google.android.c2dm.intent.RECEIVE" />
                 <category android:name="za.co.foo.android.financials" />
             </intent-filter>
             <!-- Receive the registration id -->
             <intent-filter>
                 <action android:name="com.google.android.c2dm.intent.REGISTRATION" />
                 <category android:name="za.co.foo.android.financials" />
             </intent-filter>
        </receiver>

        <receiver android:name="za.co.foo.android.financials.IntentReceiver" />

        <service android:name="com.urbanairship.push.PushService" />

    </application>

</manifest>

下面是我的 IntentReceiver

public class IntentReceiver extends BroadcastReceiver {

    private static final String logTag = "IR Intent Receiver";

    @Override
        public void onReceive(Context context, Intent intent) {
        Log.i(logTag, "Received intent: " + intent.toString());
        String action = intent.getAction();

        if (action.equals(PushManager.ACTION_PUSH_RECEIVED)) {
            int id = intent.getIntExtra(PushManager.EXTRA_NOTIFICATION_ID, 0);

            Log.i(logTag, "Received push notification. Alert: "
                    + intent.getStringExtra(PushManager.EXTRA_ALERT)
                    + " [NotificationID="+id+"]");

            logPushExtras(intent);

        } else if (action.equals(PushManager.ACTION_NOTIFICATION_OPENED)) {
            Log.i(logTag, "User clicked notification. Message: " + intent.getStringExtra(PushManager.EXTRA_ALERT));

            logPushExtras(intent);

            Intent launch = new Intent(Intent.ACTION_MAIN);
            launch.setClass(UAirship.shared().getApplicationContext(), InvestorRelations.class);
            launch.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
            launch.putExtra("FromNotification", true);

            UAirship.shared().getApplicationContext().startActivity(launch);

        } else if (action.equals(PushManager.ACTION_REGISTRATION_FINISHED)) {
            Log.i(logTag, "Registration complete. APID:" + intent.getStringExtra(PushManager.EXTRA_APID)
                    + ". Valid: " + intent.getBooleanExtra(PushManager.EXTRA_REGISTRATION_VALID, false));
        }

    }

    public void logPushExtras(intent) {
        //Does some logging stuff
    }
}

任何帮助将是巨大的。

Any help would be great

修改

附带仅为我公司名称的整个舱单变更为富。

Included the entire manifest with only my company name changed to "foo".

修改

事实证明，我的应用程序也同时关闭，但不经过强制关闭接收通知。阅读这个的问题后，已实现。

As it turns out, my app does receive notifications while closed, but not after a force-close. Realised after reading this question.

推荐答案

原来，通知运行良好的应用程序是否正在运行。问题是，当应用程序被强制关闭。

It turns out the notifications worked fine whether the app was running or not. The problem was when the app was force-closed.

我觉得实际的问题是沿的BroadcastReceiver的线条被杀害时，应用程序是力封闭的，但我不知道的东西。

I think the actual problem is something along the lines of the BroadcastReceiver being killed when the app is force closed but I'm not sure.

这是刚刚结束的问题了，因为它是不太可能，现在我意识到这个问题是不同的问题标题来解决。

This is just to close the question off because it's unlikely to be solved now that I realise the problem is different to the question title.
