Am bring an idea up on how to develop android chat app using php, mysql, Json as backend, so let start with the app splash screen, u can also come up with or idea and code here.

*****Splash Screen Implementation******

In this tutorial I’ll be covering implementation of splash screen. One is showing splash screen using a timer which takes some time to fetch required information. Both the tutorial are same except the splash screen activity. In order to implement splash screen we are going to create a separate activity for splash and once it closes we launch our main activity.bSo let’s get started by creating a new project
1. Android Splash Screen Using Timer
1. Create a new project in Eclipse or Android studio by navigating to File ⇒ New Android ⇒ Application Project and fill required details. (I kept my main activity name as LoginActivity.java)
2. For Splash Screen we are creating a separate activity. Create a new class in your package and name it as SplashScreen.java
3. Open your your AndroidManifest.xml file and make your splash screen activity as Launcher activity.

AndroidManifest.xml

<?xml version="1.0"encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.nairaland.Chat" android:versionCode="1" android:versionName="1.0">
<uses-sdk android:minSdkVersion="8" android:targetSdkVersion="17"/> <application android:allowBackup="true"
android:icon="@drawable/ic_launcher"
android:label="@string/app_name"
android:theme="@style/AppTheme">
<!-- Splash screen -->
<activity android:name="com.nairaland.Chat.Activity.SplashScreen"
android:label="@string/app_name"
android:screenOrientation="portrait"
android:theme="@android:style/Theme.Black.NoTitleBar">
<intent-filter>
<action android:name="android.intent.action.MAIN"/><category android:name="android.intent.category.LAUNCHER"/>
</intent-filter>
</activity>
<!-- Login activity -->
<activity android:name="com.nairaland.Chat.Activity.LoginActivity"
android:label="@string/app_name">
</activity>
</application>
</manifest>

4. Create a layout file for splash screen under res ⇒ layout folder. I named the layout file as activity_splash.xml. This layout normally contains your app logo or company logo.

activity_splash.xml

<?xml version="1.0"encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="@drawable/background">
<ImageView
android:id="@+id/imgLogo"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerInParent="true"
android:src="@drawable/chat_logo"/>
<TextView android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_marginBottom="10dp"
android:textSize="12dp"
android:textColor="#454545"
android:gravity="center_horizontal"
android:layout_alignParentBottom="true"
android:text="www.nairaland.com"/>
</RelativeLayout>

Note: You must have a image name background.PNG and chat_logo.PNG place in your drawable or mipmap folder
5. Add the following code in SplashScreen.java activity. In this following code a handler is used to wait for specific time and once the timer is out we launched login activity.

SplashScreen.java

package com.nairaland.Chat.Activity;
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.os.Handler;

public class SplashScreen extends Activity {// Splash screen timer
private static int SPLASH_TIME_OUT =3000;
@Override protected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);
setContentView(R.layout.activity_splash);
newHandler().postDelayed(newRunnable() {/** Showing splash screen with a timer. This will be useful when you* want to show case your app logo / company*/
@Override public void run() {// This method will be executed once the timer is over// Start your app main activity
Intent i = newIntent(SplashScreen.this, LoginActivity.class);
startActivity(i);// close this activity
finish();
}
},
SPLASH_TIME_OUT);
}
}

*****Login Implementation******

Nice tutorial

*Spreads mat*

dhtml18 u dey here OK am posting login very soon

How do you intend to implement real time messaging?

still think about that also or do u know how to do DAT without d use of firebase

Have u looked into XMPP?

am watching

donTee01:

Have u looked into XMPP?

yea i don't want that ave done d login banned register user using php mysql and Json as api
I also want to use php mysql and Json for private chat I can also use php mysql and Json for group chat and follow member

I mean EXtensible Messaging and Presence Potocol(XMPP) not XAMP

dhtml18:
am watching

Pls, have you worked with xmpp or do u have any idea on its implementation?

am not talking about xamp am talking about d app backend

You guys should please not distract this thread, I am just an observer on this thread

XMPP is more advanced and require higher level of expertise to implement. If you want to learn about it implementation you can check this repo

https://github.com/siacs/Conversations

It's a complete instant messaging App implemented with XMPP protocol.

^^I agree with you, but however, there is no good reason to disrupt this thread. There are many approaches to a solution.

Firebase is very easy to get started with. @op carry on.

^^^and firebase is actually easier to setup compared to the xmpp things. As a matter of fact, GCM too is easier to setup.

Firebase, GCM and Co all uses XMPP server.
I am not disrupting this thread.

I was also told whatsapp use xmpp server

Okay, adenuga please continue your tutorial (and let us skip anything extraneous for now, it is distracting)

sorry 4 d late comment I will continue 2morrow

I'm stunned by your post but IMO, I'll love to learn how to jump before I learn how to fly.... Teach us how to open an offline register and login app before connecting to get info from server or else you're gonna twist things for we learners

Am planing on how to make d app send instant message using json php mysql am thinking on refreshing d activity in background every 1second or milisecond

Polling for data every second is bad on a web app not to now talk of an Android app that has to be very smooth and data efficient.

Please teach us the normal way, the way you would do it on a production app.

You can use FireBase to achieve this!!

.......

Refreshing every 1 seconds even when nobody is online is bad so make it 4 - 10 seconds WHEN at every 60seconds interval, there is a user online waiting to send message.

This means that it is when a user is online that you run a timer of 4 or 2 seconds interval, instead use a 1 minute interval to check if any user is online at all. Use a background service and Timer to continue running every time to fetch data and when there is a new message, display the message....
