it was pass a data 1st activity to other activity run

example android hello world

hello friends

today we study about our android fist example HELLO WORD ,

TO SHOW IN YOUR ANDROID PHONE  with example and setting up ANDROID STUDIO .

and also setting to your mobile to run application IN ANDROID  SMART PHONE



NOW WE START

1) SETTING UP STUDIO ,

• REFER DOWNLOAD A JAVA UPDATE VERSION AND INSTALL IN YOUR PC OR LAPTOP .
• GIVE PATH TO JAVA  follow link https://www.javatpoint.com/how-to-set-path-in-java

• now download ANDROID STUDIO FROM GOOGLE ,PURIFIER NEW VERSION AT AVAILABLE IN THAT SITE  https://developer.android.com/studio/index.html
  
    

• AFTER download run .it takes some time to download component so make sure to some passion , it take more than 1 hour ,

• now start your android project with empty activity . 

EXAMPLE 

HELLO WORLD,

The Main Activity File

The main activity code is a Java file MainActivity.java. This is the actual application file which ultimately gets converted to a Dalvik executable and runs your application. Following is the default code generated by the application wizard for Hello World! application −

package com.example.helloworld;

import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;

public class MainActivity extends AppCompatActivity {
   @Override
   protected void onCreate(Bundle savedInstanceState) {
      super.onCreate(savedInstanceState);
      setContentView(R.layout.activity_main);
   }
}

The Layout File

The activity_main.xml is a layout file available in res/layout directory, that is referenced by your application when building its interface. You will modify this file very frequently to change the layout of your application. For your "Hello World!" application, this file will have following content related to default layout −

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
   xmlns:tools="http://schemas.android.com/tools"
   android:layout_width="match_parent"
   android:layout_height="match_parent" >
   
   <TextView
      android:layout_width="wrap_content"
      android:layout_height="wrap_content"
      android:layout_centerHorizontal="true"
      android:layout_centerVertical="true"
      android:padding="@dimen/padding_medium"
      android:text="@string/hello_world"
      tools:context=".MainActivity" />
      
</RelativeLayout>

Step by step:

1. Connect your phone to computer via USB.
2. Development option create by click on about phone> Kernel version (tap on that at list 8 time thane create a developer option . on your hend-set ) now time in a Mi and VIVO   phone not required to create option , it was automatic generated by  connect usb  to your system .
3. Enable USB debugging on your phone: Settings -> Applications -> Development -> USB debugging.
4. Change Run configuration in your Eclipse project: right click -> Run As -> Run Configuration
