गतिविधि इसे न्यूनतम करने के बाद अपनी सेवा से संबंध नहीं रखती है

मुझे कम से कम करने के बाद एक गतिविधि में समस्या है। सब कुछ ठीक चल रहा है जब मैं एक गतिविधि शुरू करता हूं और स्टार्ट बटन दबाता हूं। लेकिन जब मैं गतिविधि को कम करता हूं और इसे फिर से अधिकतम करता हूं, तो यह मेरे बटन और आदेशों का जवाब नहीं देता है। किसी को पता है क्या करना है? यह मेरा पहला एंड्रॉइड ऐप है इसलिए मुझे नहीं पता कि क्या हो रहा है ..

यहाँ मेरी कक्षाएं हैं:
