Activity Life Cycle mein kuch important states hoti hain jo har Activity ke different stage mein trigger hoti hain. In states ko samajhna important hai kyunki inhi ke through app ki functioning aur performance kaafi influence hoti hai.

• onCreate(): Jab Activity ka instance create hota hai, tab onCreate method call hota hai. Yeh method initial setup ke liye hota hai jisme UI elements ko set karna, data load karna, aur initializations perform kiye jate hain. Is stage par app ke liye sabse pehle activity ka layout load hota hai.
• onStart(): Jab Activity visible ho jati hai, tab onStart method call hota hai. Iska matlab hai ki Activity screen par aa gayi hai lekin abhi user ke saath interact nahi kar rahi hoti. Yeh method Activity ke start hone ke baad turant call hota hai.
• onResume(): Jab Activity user ke saath interact karne ke liye ready hoti hai, tab onResume method call hota hai. Is stage par app user ke interaction ke liye fully ready ho jaata hai. Jab bhi Activity ko foreground me lana hota hai, tab onResume call hota hai.
• onPause(): Jab Activity kisi aur activity ke saath replace hoti hai ya app background me jata hai, tab onPause method call hota hai. Is stage par aapko apne resources ko release kar dena chahiye jise app ko background me hone par koi unwanted activity na ho.
• onStop(): Jab Activity background me chali jati hai ya screen se completely disappear ho jaati hai, tab onStop method call hota hai. Is state me app ke resource ko free karna aur unwanted memory use ko minimize karna zaruri hota hai.
• onRestart(): Jab Activity ko background se dobara foreground me laana hota hai, tab onRestart method call hota hai. Is method mein app ko dobara se resume hone ke liye ready kiya jaata hai, jaise ki data reload karna ya state ko restore karna.
• onDestroy(): Jab Activity completely finish ho jati hai, tab onDestroy method call hota hai. Yeh last stage hoti hai jahan aap apne resources ko release karte hain aur Activity ko destroy karte hain.
