In this tutorial, I'll show you how to develop Android Login and Registration functionalities with PHP, MySQL, and Volley Library. I have explained everything step-by-step with a simple and secure way of implementation. Let's build a professional-looking login and registration form and implement the functionalities in code. We'll be using XAMPP localhost connection for this demonstration. For sending an HTTP request to the server we'll use Android Volley library. So, let's get started.

Hello Sandip, as a matter of fact many of your video are helping me in my journey to learn using android studio. Thanks for this excellent job. I was able to create new recors on my DB using your approach, ( yes I did it) now I'm wondering how to pass decimal number introduced in a textView( set as decimal numer) to my BD. the stringRequest seems to accept only string, now I expect to load a Integer in my DB. Any suggestion ? Thanks

Yes, correct. And since we're running the app on the emulator, we need to add: 10.0.2.2/ or, 10.0.2.2/ before the folder name (located in xampp\htdocs). So, the complete url then becomes: 10.0.2.2/login/login.php or, 10.0.2.2/login/login.php in our case. Hope things are clear!

Can you please help me with this error? Thank you so much.

@SandipBhattacharya 2 жыл бұрын

@Emre Turan, Hi, this exception "...Trust anchor for certification path not found." is usually caused if you haven't configured your web server properly and it doesn't have the root certificate or is missing some public key or a .crt file. I don't know which web server you're using, check your web server config first. Also, try using "https" instead of "http" in the url.

what if theres no java option when i choose java or kotlin, the only available language is kotlin, it is still okay ?

@SandipBhattacharya 6 ай бұрын

Thank you for asking this question. Follow these 7 steps: 1. In the "New Project" screen select default (Kotlin DSL (build.gradle.kts)) for "Build configuration language", click Finish. 2. Delete "MainActivity.kt". Manually add a Java class to your project. Right-click on the package > New > Java Class. You can name it "MainActivity.java". Extend AppCompatActivity. Click "AppCompatActivity", press ALT+ENTER and import the package: import androidx.appcompat.app.AppCompatActivity; Override onCreate() method. For example: package com.example.myapplication; import android.os.Bundle; import androidx.annotation.Nullable; import androidx.appcompat.app.AppCompatActivity; public class MainActivity extends AppCompatActivity{ @Override protected void onCreate(@Nullable Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.layout_main); } } 3. Right-click on res and create a Directory called "layout" and add a layout XML file ( named layout_main.xml) by right-clicking 'layout' > New > XML > Layout XML file. Name it ' layout_main'. Select a Root Tag (E.G. LinearLayout). For example: 4. Open themes.xml inside 'values' folder and add this theme: true false true @null 5. Open AndroidManifest.xml and replace the theme (2 places, in application tag and in activity tag): android:theme="@style/Theme.AppCompat.Light.NoActionBar.FullScreen". 6. You may need to Build > Clean Project. 7. Success! That's how it's done! ✨🙌🚀 Hope that helps!

Ok. Make sure Skype is completely closed while running xampp since Skype has known issue with xampp. Another option would be to uninstall xampp and use wamp. If the problem persists, you can send me an enquiry through my website and I'll look into that.

"'"; Everything I inputted goes to "Failed login", even if I placed a correct id(or email) and password.
