我有一个问题。当我调用 finish() 方法时， Activity 仍然保留在任务管理器中，如果用户从任务管理器重新启动它，我的 Activity 会收到旧的 Intent 。如果该 Intent 是从推送通知发送的，我会有不希望的 react :我的应用程序使用推送通知数据启动流程 Intent 。

如何正确管理我的 Activity 中的推送通知 Intent 行为以避免错误的 Activity 状态？

我的应用收到推送通知并形成待处理的推送响应 Intent :

       final NotificationManager mNotificationManager = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);

        int defaultOptions = Notification.DEFAULT_LIGHTS;
        defaultOptions |= Notification.DEFAULT_SOUND;

        Intent intentAction = new Intent(context, MainActivity.class);
        intentAction.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_SINGLE_TOP);
        intentAction.putExtra(BUNDLE_COLLAPSE_KEY, data.getString(BUNDLE_COLLAPSE_KEY));
        intentAction.setAction(CUSTOM_ACTION);

        final PendingIntent pendingIntent = PendingIntent.getActivity(context, 0, intentAction, PendingIntent.FLAG_UPDATE_CURRENT);
        int notificationFlags = Notification.FLAG_AUTO_CANCEL;
        final Notification notification = new NotificationCompat.Builder(context).setSmallIcon(R.drawable.icon_splash)
                .setContentTitle(context.getResources().getString(R.string.app_name))
                .setContentText(data.getString(BUNDLE_PUSH_CONTENT_DATA))
                .setContentIntent(pendingIntent)
                .setAutoCancel(true)
                .setDefaults(defaultOptions)
                .getNotification();
        notification.flags |= notificationFlags;
        mNotificationManager.notify(NOTIFICATION_ID, notification);

用户通过推送进入应用程序后，应用程序显然会通过 CUSTOM_ACTION 接收 Intent 并执行一些工作:

private void intentProcess(Intent intent) {
    boolean customAction = intent.getAction().equals(GCMPushReceiver.CUSTOM_ACTION);
    if (customAction) {
        //push reaction, do some staff with intent
    } else {
        //no push reaction, user just open activity
    }
}

我从 onCreate 和 onNewIntent 调用 intentProcess 方法:

public class MainActivity extends FragmentActivity {
//this case if my app closed and user tap on push
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        /* ... */
        intentProcess(getIntent());
    }
//this case if my app opened and user tap on push
    @Override
    protected void onNewIntent(Intent intent) {
        super.onNewIntent(intent);
        intentProcess(intent);
    }
}

list 中的 Activity 声明:

    <activity
        android:name=".ui.activity.MainActivity"
        android:label="@string/app_name"
        android:screenOrientation="portrait"
        android:windowSoftInputMode="adjustResize">
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />
            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>

最佳答案

尝试使用它

int id= NotificationID.getID();
final PendingIntent pendingIntent = PendingIntent.getActivity(context, id, intentAction, PendingIntent.FLAG_UPDATE_CURRENT);

// rest of your code 

notificationManager.notify(id, notification);

添加一个新类

    public class NotificationID {

    /**
     * An AtomicInteger is used in applications such as atomically incremented
     * counters, and cannot be used as a replacement for an Integer. However,
     * this class does extend Number to allow uniform access by tools and
     * utilities that deal with numerically-based classes.
     */
    private final static AtomicInteger c = new AtomicInteger(0);

    /**
     * Method to the automatically incremented int value.
     * 
     * @return
     */
    public static int getID() {
        return c.incrementAndGet();
    }
}

每次生成通知时，它都会创建具有不同 ID 的新 Intent 。

如果您不希望您的 Activity 显示/添加到任务管理器，请在 AndroidManifest 的 Activity 标签中添加这些行。

android:excludeFromRecents="true"
android:noHistory="true"

关于Android - Intent 管理。如果用户从任务管理器打开应用程序，则重新发送旧 Intent ，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/25357904/
