本文介绍了安卓M:我怎样才能获得当前的前台活动的包名(从服务)的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!

问题描述

有容易得到从在Android L时ActivityManager服务正在运行的任务的列表,并且当前活动任务首先被返回。但是,不要在Android M编辑任何更多的,则返回列表仅包含我的应用程序的任务。有什么办法来解决呢?

我的code:

 名单,其中,ActivityManager.RunningAppProcessInfo> runningAppProcessInfos = activityManager.getRunningAppProcesses();
的for(int i = 0; I< runningAppProcessInfos.size();我++){
    ActivityManager.RunningAppProcessInfo runningAppProcessInfo = runningAppProcessInfos.get(ⅰ);
    如果(runningAppProcessInfo.importance == ActivityManager.RunningAppProcessInfo.IMPORTANCE_FOREGROUND){
        返回runningAppProcessInfo.pkgList [0];
    }
}
 

解决方案

您可以使用下面code和获取当前的前台活动的包名。

 如果(android.os.Build.VERSION.SDK_INT> = android.os.Build.VERSION_ codeS.LOLLIPOP){
            UsageStatsManager USM =(UsageStatsManager)getSystemService(usagestats);
            很长一段时间= System.currentTimeMillis的();
            名单< UsageStats> APPLIST = usm.queryUsageStats(UsageStatsManager.INTERVAL_DAILY,
                            时间 -  1000 * 1000,时间);
                    如果(APPLIST =空&安培;!&安培; appList.size()大于0){
                        SortedMap的<长,UsageStats> mySortedMap =新TreeMap的<长,UsageStats>();
                        对于(UsageStats usageStats:APPLIST){
                            mySortedMap.put(usageStats.getLastTimeUsed(),
                                    usageStats);
                        }
                        如果(mySortedMap =空&安培;!&安培;!mySortedMap.isEmpty()){
                            currentApp = mySortedMap.get(
                                    。mySortedMap.lastKey())getPackageName();
                        }
                    }
        } 其他 {
            名单< ActivityManager.RunningAppProcessInfo>任务=上午
                            .getRunningAppProcesses();
                    currentApp = tasks.get(0).processName;
        }
 

修改

添加此权限到清单文件。

 <使用-权限的Andr​​oid:名称=android.permission.GET_TASKS/>
<使用-权限的Andr​​oid:名称=android.permission.PACKAGE_USAGE_STATS工具:忽略=ProtectedPermissions/>
 

注意

请确保您需要配置自定义您的设备来获得输出设置,您可以设置>安全性>应用程序与使用权限配置它>然后让你的应用程序的权限

It is easy to get a list of running tasks from the ActivityManager service on Android L, and the current active task is returned first. But it don't work on Android M any more, the return list only contains my app task. Is there any way to settle it?

My code:

List<ActivityManager.RunningAppProcessInfo> runningAppProcessInfos = activityManager.getRunningAppProcesses();
for (int i = 0; i < runningAppProcessInfos.size(); i++) {
    ActivityManager.RunningAppProcessInfo runningAppProcessInfo = runningAppProcessInfos.get(i);
    if (runningAppProcessInfo.importance == ActivityManager.RunningAppProcessInfo.IMPORTANCE_FOREGROUND) {
        return runningAppProcessInfo.pkgList[0];
    }
}
解决方案

you can use below code and get the current foreground activity package name.

   if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.LOLLIPOP) {
            UsageStatsManager usm = (UsageStatsManager) getSystemService("usagestats");
            long time = System.currentTimeMillis();
            List<UsageStats> appList = usm.queryUsageStats(UsageStatsManager.INTERVAL_DAILY,
                            time - 1000 * 1000, time);
                    if (appList != null && appList.size() > 0) {
                        SortedMap<Long, UsageStats> mySortedMap = new TreeMap<Long, UsageStats>();
                        for (UsageStats usageStats : appList) {
                            mySortedMap.put(usageStats.getLastTimeUsed(),
                                    usageStats);
                        }
                        if (mySortedMap != null && !mySortedMap.isEmpty()) {
                            currentApp = mySortedMap.get(
                                    mySortedMap.lastKey()).getPackageName();
                        }
                    }
        } else {
            List<ActivityManager.RunningAppProcessInfo> tasks = am
                            .getRunningAppProcesses();
                    currentApp = tasks.get(0).processName;
        }

Edit

Add this permission in to Manifest file.

<uses-permission android:name="android.permission.GET_TASKS" />
<uses-permission android:name="android.permission.PACKAGE_USAGE_STATS" tools:ignore="ProtectedPermissions" />

Note

Make sure you need to configure custom setting in your device to obtain the output you can config it with Setting > Security > Apps with usage access > Then enable your app permission
