Mobile Phone Se Android Application Kaise Banaye

Mobile Phone Se Android Application Kaise Banaye

Aaj hum apne mobile phone ki madad se ek simple aur professional Android IPTV Application banana seekhenge.

Is tutorial mein hum Android application kaise banayi jaati hai, woh step by step detail mein samjhenge. Yeh tutorial beginners ko dhyan mein rakhkar banaya gaya hai, taaki kisi bhi beginner ko samajhne mein koi dikkat na ho.

Step 1: Android Code Studio Mein Naya Project Banana

Agar aapke paas Android Code Studio nahi hai, to aap ise hamare Telegram channel se download kar sakte hain.

Sabse pehle Android Code Studio application ko open karein. App open hone ke baad Plus (+) / Create Project button par click karke ek naya project create karein.

Project create karte waqt Basic Activity select karein. Iske baad project ka naam set karein aur package name com.my.app rakhein.

Ab language mein Java select karein aur Minimum SDK ke liye API 21 select karein. Sabhi settings complete karne ke baad Create button par click karein.

Project Ka Structure

Ab humein apne project ka structure banana hai. Project ka structure kuch is tarah hona chahiye:

Ab niche se har ek file ka code diya jayega. Aapko apne project ke structure ke according har file mein uska respective code paste karna hai.

Code paste karte waqt dhyan rakhein ki file ka naam aur folder location bilkul sahi ho. Agar file ka naam ya location galat hui, to application mein error aa sakta hai.
