Getting started in basic Android programming

It’s more fun in programming – many people consider this kind of stuffs as their fashion way of exploring the world of technology by developing computer programs and mobile apps that runs on various platform. The latest trends is developing Apps in Android, why Android? Now a day, smartphone are widely used by many users where the powerof Android Operating System runs dependent on its hardware. To learn Android programming is not a big deal to cover all programming languages to enable you writes mobile application. However, basic knowledge in programming is advantage. Basic Android programming was based (Linux Kernel) on Java, its looks like very similar. For instance, Android runs dependent on its Software Development Kit (SDK) every time you create and run the program. To setup Android, you must download first the Android Developer Tools (ADT) bundled that includes everything you need for developing apps. This package includes the following:

·         Eclipse + ADT plugin

·         Android SDK Tools

·         Android Platform-tools

·         The latest Android platform

·         The latest Android system image for the emulator

 It’s not quite difficult to configure if you follow the steps.

Android comes in many flavors (version) to taste, and makes sweeter as many flavors to come. For developers, you must aware the target version wants to develop Apps because the version may vary the compatibility of hardware in every device. It includes the target device, if it is design for smartphone, Tablets, or TV. In addition, common issues in developing Apps are the compatibility of the said versions. It’s not like a desktop application where the hardware and screen size has minimal issue.  

My Android Apps I made will run on other smartphone devices?

Not necessary! Android will run only on its own hardware compatibility, if you have an Android Phone any Apps can install on your device. However, as what I have said, it depends on what version of Android Phone and Apps you have. If you are going to develop Apps, you must specify the minimum target version in order the other Android users not get problem during their installation. For instance, make a regular updates about your Apps by simply giving them a versions.

Android sample code in XML 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"

    android:paddingBottom="@dimen/activity_vertical_margin"

    android:paddingLeft="@dimen/activity_horizontal_margin"

    android:paddingRight="@dimen/activity_horizontal_margin"

    android:paddingTop="@dimen/activity_vertical_margin"

    tools:context=".AndroidBasic" >

    <TextView

        android:layout_width="wrap_content"

        android:layout_height="wrap_content"

        android:text="@string/hello_world" />

</RelativeLayout>

Android sample code

package com.test.test;

import android.os.Bundle;

import android.app.Activity;

import android.view.Menu;

public class AndroidBasic extends Activity {

                @Override

                protected void onCreate(Bundle savedInstanceState) {

                                super.onCreate(savedInstanceState);

                                setContentView(R.layout.activity_android_basic);

                }

                @Override

                public boolean onCreateOptionsMenu(Menu menu) {

                                // Inflate the menu; this adds items to the action bar if it is present.

                                getMenuInflater().inflate(R.menu.android_basic, menu);

                                return true;

                }

}

Keep on exploring Android Programming, many websites will teach you online regarding this matter. Hope this is very helpful in Basic understanding in Android Programming.
