PackageManager's applicationInfo.name is always null

PackageManager pm = this.getPackageManager();
ActivityManager am = (ActivityManager) this.getSystemService(Context.ACTIVITY_SERVICE);

List<RunningAppProcessInfo> runningAppProcesses = am.getRunningAppProcesses();

for(RunningAppProcessInfo process : runningAppProcesses) {
    try {
        ApplicationInfo ai = pm.getApplicationInfo(process.processName, PackageManager.GET_META_DATA);
        Log.d(TAG, applicationInfo.name + "");
    } catch (NameNotFoundException e) {
        e.printStackTrace();
    }
}

process.processName returns a valid package name but applicationInfo.name is always null.
