FATAL EXCEPTİON:main hatası ...

Android Studio üzerinde geliştirmekte olduğum bir projede ilk olarak android sürüm sıkınıtısı yaşamaktaydım.Bu sorunu minimumSDK ayarlarmaları ile çöztüm sanırsam.Daha sonra android sürümü 5.0 altında olan bir telefonda uygulmamı run etmeye çalıştığımda aşağıdaki hataları alıyorum.5.0 üzeri telefonlarda sağlıklı çalışıyor uygulama.
