ActivityManager.getRunningTasks 已弃用 android [英] ActivityManager.getRunningTasks is deprecated android

问题描述

我正在 android 中处理推送通知，我使用下面的方法来显示通知，但问题是现在 ActivityManager.getRunningTasks(1);正在被弃用.我从一个 stackoverflow 问题中读到:您可以使用 getAppTasks() 返回一个 List，您可以在其中使用 RecentTaskInfocode>getTaskInfo"，但我不知道如何使用它.请在这方面帮助我.

I am working on push notification in android where i am using a below method to show notification, but the problem is that now ActivityManager.getRunningTasks(1); is being deprecated. From one stackoverflow question i read that: " you can use getAppTasks() returning a List<AppTask> where you can get the RecentTaskInfo with getTaskInfo" but i can't figure it out how to use it. Please help me out here in this regard.

private void postNotification(Context ctx, Intent intent) {
        try {
            if (intent == null) {
                Log.d(TAG, "Receiver intent null");
            } else {
                String action = intent.getAction();
                if (action.equals("com.ziza.cy.UPDATE_STATUS")) {

                    JSONObject json = new JSONObject(intent.getExtras()
                            .getString("com.parse.Data"));

                    String type = json.getString("type");

                    if (type.equals("AlertNotification")) {

                        String msg = json.getString("header");
                        String title = "ncy";

                        ActivityManager am = (ActivityManager) ctx

                        List<RunningTaskInfo> taskInfo = am.getRunningTasks(1);
                        ComponentName componentInfo = taskInfo.get(0).topActivity;

                        // don't show notification if app is in foreground
                        if (componentInfo.getPackageName().equalsIgnoreCase(
                                ctx.getPackageName())) {

推荐答案

这应该可以帮助您入门

ActivityManager activityManager = (ActivityManager) context.getSystemService(Context.ACTIVITY_SERVICE);
List<ActivityManager.AppTask> tasks = activityManager.getAppTasks();

for (ActivityManager.AppTask task : tasks) {
    Log.d(TAG, "stackId: " + task.getTaskInfo().stackId);
}
