Android 5.0+ getRunningTasks 已弃用

Question

我已经完成了这个question and this question. But with the help of this library我现在可以使用以下代码获取前台任务列表。

if (Build.VERSION.SDK_INT < Build.VERSION_CODES.LOLLIPOP) { //For versions less than lollipop
            ActivityManager am = ((ActivityManager) getSystemService(ACTIVITY_SERVICE));
            List<ActivityManager.RunningTaskInfo> taskInfo = am.getRunningTasks(5);
            top = taskInfo.get(0).topActivity.getPackageName();
            Log.v(TAG, "top app = " + top);
        }else{ //For versions Lollipop and above
            List<AndroidAppProcess> processes = ProcessManager.getRunningForegroundApps(getApplicationContext());
            Collections.sort(processes, new ProcessManager.ProcessComparator());
            for (AndroidAppProcess process : processes) {
                if (process.foreground) {
                    top =process.name;
                    Log.v(TAG,top);
                }
            }
        }

在这里，对于 Android 5.0+，我得到了所有运行前台进程，但我无法断定哪个应用是顶级应用。

以上代码的输出（对于 else 条件）

com.android.vending
com.google.android.gms
com.google.android.googlequicksearchbox
com.google.android.videos
com.test1
com.naag.testing
com.example.android.gettask

我最喜欢的应用是 com.google.android.videos

现在如何以编程方式确定 com.google.android.videos 是上面列表中的顶级应用程序？

applocker（或类似 applocker）应用程序如何在 5.0+ 上运行？希望有人帮助这对某人有帮助。

Answer 1

"apps with usage accesse"功能有时可以满足您的需求

Answer 2

所以这是一个更新。在 5.0 和 5.1.1 设备中测试。完美运行。

if (Build.VERSION.SDK_INT < Build.VERSION_CODES.LOLLIPOP) { //For versions less than lollipop
            ActivityManager am = ((ActivityManager) getSystemService(ACTIVITY_SERVICE));
            List<ActivityManager.RunningTaskInfo> taskInfo = am.getRunningTasks(5);
            top = taskInfo.get(0).topActivity.getPackageName();
            Log.v(TAG, "top app = " + top);
        }else{ //For versions Lollipop and above
            List<AndroidAppProcess> processes = ProcessManager.getRunningForegroundApps(getApplicationContext());
            Collections.sort(processes, new ProcessManager.ProcessComparator());
            for (int i = 0; i <=processes.size()-1 ; i++) {
                if(processes.get(i).name.equalsIgnoreCase("com.google.android.gms")) { //always the package name above/below this package is the top app
                    if ((i+1)<=processes.size()-1) { //If processes.get(i+1) available, then that app is the top app
                        top = processes.get(i + 1).name;
                    } else if (i!=0) { //If the last package name is "com.google.android.gms" then the package name above this is the top app
                        top = processes.get(i - 1).name;
                    } else{
                        if (i == processes.size()-1) { //If only one package name available
                            top = processes.get(i).name;
                        }
                    }
                    Log.v(TAG, "top app = " + top);
                }
            }
        }

多亏了这个library

现在我可以在 Android 5.0+

中获得前台任务
