How To Add Offline Login System In Andlua Project| Detailed Guide

Introduction

Aaj hum ek aise important feature par baat karne wale hain jo aapke AndLua+ projects ko ek professional look aur basic security layer provide karta hai – ek Offline Login System. Agar aap chahte hain ki aapka banaya hua app sirf authorized users hi use kar paayein, to yeh tutorial aapke liye hai.

Sochiye: Aapne koi personal tool banaya hai, koi custom script ya koi private application jo aap apne doston ya specific group ke saath share karna chahte hain. Aise mein, aap nahi chahenge ki koi bi ise open kar ke use kar le. Isi problem ka solution hai ek simple login system.

Aaj hum jo system banayenge, uski khaas baatein yeh hain:

App open hote hi ek floating login window aayegi.
Galat credentials dene par error message dikhega.
Sahi credentials dene par welcome message ke saath app open ho jayegi.
Users agar password bhool jaayein to “Get Key” option se aapke Telegram channel ya YouTube page par pahunch sakte hain.

Yeh system offline hai, matlab internet ki zaroorat nahi padegi. Saara data locally stored hoga.

Video Tutorial

Agar aap is tutorial ko video ki madat se samajhna chahte hai to maine eak video bana diya hai jisme maine sab kuch step by step bataya hai [embedded below]

Chaliye, step-by-step seekhte hain ki ise kaise implement karte hain.

Pehle Tools aur Files Ko Taiyar Karein

Kisi bhi construction ka kaam shuru karne se pehle, aapko apne tools aur material ikattha karne hote hain. Yahan bhi kuch similar hai.

1. MT Manager:
Yeh ek powerful file manager aur editor hai. Iski madad se aap code files ko edit, copy, aur manage kar paayenge. Is app ko aap online search karke easily download kar sakte hain.

2. AndLua+ App:
Yeh aapka main coding platform hai, jahan aap apna project banayenge aur is login system ko add karenge.

3. Login System Code File:
Aapko ek pre-written code file ki zaroorat padegi jisme login system ka base code likha hoga.

In teeno cheezein download karke install kar lein. Ab aap kaam ke liye taiyaar hain.

Step 1: Code File Ko Samajhna aur Customize Karna

Sabse pehle, humein jo code file mili hai use open karke use apne hisaab se customize karna hai.

MT Manager open karein aur wo downloaded code file dhoondhein.
File ko open karein. Aapko Lua code dikhega.
Line 34 par jaayein. Yahan aapko app ka naam likha hua milega. Is jagah apna desired naam likhein. Ye naam login window ke title ya welcome message mein show hoga.
- Example: appname = "DevelopEye Tutorials" ki jagah appname = "Your App Name" likh sakte hain.
Username aur Password Set Karna: Thoda neeche scroll karein. Aapko kuch lines mein default username aur password set kiye huye milenge. Jaise:
- username = "A"
- password = "A"
  In values ko apni marzi ke strong username aur password se badal dein. Yaad rahe, yeh values wahi rahengi jo user ko app mein daalni hongi.
- Example: username = "admin123" aur password = "securePass@123" rakhein.

Yeh dono steps important hain kyunki yeh aapke app ki pehchaan aur security define karte hain.

Step 2: Code Ko Apne AndLua+ Project Mein Paste Karna

Ab humein is customized code ko apne asli project mein le jaana hai.

MT Manager mein hi, code file khol ke rakhain.
Poora code select karein. Aisa karne ke liye, code ke start se end tak select karein. Ya phir Ctrl+A (Select All) ka use kar ke saara code copy kar lein.
Ab AndLua+ app open karein.
Apna wo project open karein jismein aap yeh login system add karna chahte hain.
Project ki main.lua file khollein.
File ke last mein jaayein, khaali space dhoondhein (ya nayi lines add karein).
Yahan jaakar copied code ko paste kar dein.
Dhyaan Rakhein: Kahi aas-paas koi extra curly braces } ya end statement to nahi hai jo conflict kar rahi ho. Agar hai, to use hata dein. Code saaf aur organized dikhna chahiye.

Is tarah, aapka login system ka code ab main project ka hissa ban gaya hai.

Step 3: “Get Key” Feature Ko Customize Karna

Yeh feature un users ke liye hai jo username ya password bhool jaate hain. “Get Key” button dabakar wo aapke social channel par pahunch jayenge.

Apne paste kiye hue code ke last sections mein jaayein.
Aapko ek function milega jismein Get Key button ka logic likha hoga.
Us function ke andar, openUrl("https://t.me/YourChannelName") jaise koi line hogi.
Is link ko change karke apna personal Telegram channel link ya YouTube channel link kar dein.
- Example: openUrl("https://t.me/MyPrivateGroup")
Iske aas-pass aap ek message bhi set kar sakte hain jo user ko dikhega jab wo “Get Key” dabayega. Jaise: print("Please join our Telegram channel to get the key!")

Yeh step important hai taaki users aap tak easily pahunch saken aur aap unhe sahI credentials de saken.

Step 4: Final Build aur Testing – Apna Kaam Check Karna

Ab sab kuch set hai. Ab time hai apni mehnat ka result dekhnE ka.

AndLua+ mein apna project save kar lein.
Run ya Build APK ka option choose karein taaki ek new APK file generate ho.
App ko install karein aur open karein.

Testing Ke Steps:

Pehla Test – Galat Credentials: App open karte hi login window aani chahiye. Jaane-bujhkar koi galat username/password daal kar login dabayein. Aapko ek error message dikhna chahiye (Jaise: “Wrong username or password”).
Dusra Test – Sahi Credentials: Ab wohi sahI username aur password daalein jo aapne code mein set kiye the. Is baar, aapko “Welcome [username]” jaisa message dikhna chahiye aur app properly open ho jani chahiye.
Tehra Test – Get Key Feature: App dobara run karein. Ab “Get Key” ya “Forgot Password” jaise button par click karein. Aapka browser open hokar directly aapke diye gaye Telegram/YouTube link par chala jana chahiye.

Agar yeh teeno tests successful hain, to badhai ho! Aapka offline login system perfect kaam kar raha hai.

Kuch Common Problems aur Unke Solutions (Troubleshooting)

Problem: App open hote hi crash ho jati hai.
- Solution: Galti se koi important code delete ho gaya hoga. Dobara check karein ki aapne main.lua file ke last mein code paste kiya hai, aur kisi existing necessary code ko overwrite nahi kiya hai.
Problem: Login window hi nahi aa rahi.
- Solution: Ho sakta hai code sahi se paste nahi hua. Dobara check karein ki aapne saara code copy-paste kiya hai aur koi part choota nahi hai.
Problem: Sahi password dene ke baad bhi error aata hai.
- Solution: Code mein jo username/password aapne set kiye hain, unki spelling aur capitalization (chhote-bade letters) bilkul check karein. Admin aur admin alag hain.
Problem: “Get Key” par click karne par kuch nahi hota.
- Solution: Check karein ki aapne apna Telegram/YouTube link sahi se daala hai aur link https:// se shuru ho raha hai.

Ek Zaroori Security Note

Doston, yeh ek offline login system hai. Iska matlab hai ki username aur password aapke app ke code ke andar hi stored hain. Koi bi person jo aapke code ko access kar leta hai (jaise MT Manager se decompile karke), wo yeh credentials dekh sakta hai.

Isliye, is system ko sirf basic-level ki security ke liye use karein.
Ise highly sensitive data ke liye istemal nahi karna chahiye.
Agar aapko zyada security chahiye, to online database (jaise Firebase) based login system banana hoga.

Yeh system aapke app ko casual users ya friends se protect karne ke liye perfect hai, par professional-level ki security ke liye nahi.

Conclusion
