بسته شدن خودکار برنامه بعد از مدتی که در background می مونه

سلام دوستان از عنوان که مشخصه این سوال را قبلا دوست خوبمون کریس پرسیده بودن من هم کدی را قرار دادم اما مشکلی هست که نیاز به روت داره و در اندروید های 4.2 و 4.4 و 5 عملکردی متفاوت داره و راه حل اساسی نیست.

می خوام برنامه به صورت کامل بسته بشه چون در کلاس Gمتغییرهایی وجود داره که با باز شدن مجدد برنامه گاهی اوقات هیچ اطلاعاتی از اکتیویتی جاری نشون نمیده

AndroidManifest

         <activity
            android:name=".ActivitySettings"
            android:autoRemoveFromRecents="true"
            android:excludeFromRecents="true"
            android:label="@string/app_name" >
        </activity>
