How to `getTopActivity` name or get currently running application package name in lollipop?

try this:

ActivityManager mActivityManager =(ActivityManager)this.getSystemService(Context.ACTIVITY_SERVICE);

if(Build.VERSION.SDK_INT > 20){
String mPackageName = mActivityManager.getRunningAppProcesses().get(0).processName;
}
else{
  String mpackageName = mActivityManager.getRunningTasks(1).get(0).topActivity.getPackageName();
}

we can get using UsageStats:

public static String getTopAppName(Context context) {
    ActivityManager mActivityManager = (ActivityManager) context.getSystemService(Context.ACTIVITY_SERVICE);
    String strName = "";
    try {
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
            strName = getLollipopFGAppPackageName(context);
        } else {
            strName = mActivityManager.getRunningTasks(1).get(0).topActivity.getClassName();
        }
    } catch (Exception e) {
        e.printStackTrace();
    }
    return strName;
}

private static String getLollipopFGAppPackageName(Context ctx) {

    try {
        UsageStatsManager usageStatsManager = (UsageStatsManager) ctx.getSystemService("usagestats");
        long milliSecs = 60 * 1000;
        Date date = new Date();
        List<UsageStats> queryUsageStats = usageStatsManager.queryUsageStats(UsageStatsManager.INTERVAL_DAILY, date.getTime() - milliSecs, date.getTime());
        if (queryUsageStats.size() > 0) {
            Log.i("LPU", "queryUsageStats size: " + queryUsageStats.size());
        }
        long recentTime = 0;
        String recentPkg = "";
        for (int i = 0; i < queryUsageStats.size(); i++) {
            UsageStats stats = queryUsageStats.get(i);
            if (i == 0 && !"org.pervacio.pvadiag".equals(stats.getPackageName())) {
                Log.i("LPU", "PackageName: " + stats.getPackageName() + " " + stats.getLastTimeStamp());
            }
            if (stats.getLastTimeStamp() > recentTime) {
                recentTime = stats.getLastTimeStamp();
                recentPkg = stats.getPackageName();
            }
        }
        return recentPkg;
    } catch (Exception e) {
        e.printStackTrace();
    }
    return "";
}

// TO ENABLE USAGE_STATS

    // Declare USAGE_STATS permisssion in manifest

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

    Intent intent = new Intent(Settings.ACTION_USAGE_ACCESS_SETTINGS);
    startActivity(intent);

how to get package name of application being displayed on screen in a foreground service, android?

Well, below API-Level 21 or loolipop, you can get the whole package with the activity class, but from API-22 you can't get the whole application package with activity because of some security reasons.

As you know that Android is not going to be a secure phone, so that's why activity name is restricted.
