The backend structure, database mastering, and appropriate admin and user ends were designed perfectly. High-quality support and software adjustments were also provided by the team.

App development software: So how Android apps are created. Novice users always ask themselves the question, what is an Android app. An Android app is simply a software application that is running on the Android platform.

So why do we use Android apps & who makes these apps?

The apps are created by Android developers. The job of an Android developer is to create an app that is efficient, functions properly & bug-free. We download apps based on different purposes. As we know bugs are a never-ending process which is why updates are being released frequently on the Google play store. That is why apps are being maintained until this day. The job of an Android developer is to maintain the app bug-free. So that the user gets the best experience out of the app as possible.

The Android developer’s use that is known as IDE. IDE is an integrated development environment. A popular IDE that is currently used by lots of Android developers is Google’s Android Studio. As a developer, you can use Android Studio on your laptop or PC. It is important to familiarize yourself with the Java programming language.

The things that are required to develop an Android app.

JDK [Java Development Kit]

It is nothing but software which helps you to develop any kind of java application. If you like to run an application, you definitely need to install this JDK on your PC or Laptop.

The Java code looks like this: Unistat label template microsoft worddownload free apps.

Features

  1. Java has a widely-used programming language for developing Android apps. The Java key features include:
  2. It runs on all platforms
  3. An object-oriented language
  4. The API’s allows tools for every task
  5. Easy to learn & read

Android Studio

The Android Studio is nothing but software. It integrates a development environment platform for all kinds that enables you to develop other software. The Android studio helps you to develop, run, compile, debug & test your Android apps.

So you definitely need to have programming experience in order to develop another application. Without programming experience, you cannot develop any kind of application. Both Java development Kit & Android Studio are available for all platforms or operating systems. These are open-source applications, you don’t need to pay any money to download this stuff.

App development guidelines

When comes to installing these applications, the Java development kit doesn’t need anything or any special packages. You can just click on the EXE file & you can just install it. When it comes to Android studio, it prompts you to install some packages before installation. Those packages are necessary for Android studio to function properly.

Apps For Android Phones


The android developer tools let you create interactive and powerful application for android platform. The tools can be generally categorized into two types.

  • SDK tools

  • Platform tools

SDK tools

SDK tools are generally platform independent and are required no matter which android platform you are working on. When you install the Android SDK into your system, these tools get automatically installed. The list of SDK tools has been given below −

Sr.NoTool & description
1android

This tool lets you manage AVDs, projects, and the installed components of the SDK

2ddms

This tool lets you debug Android applications

3Draw 9-Patch

This tool allows you to easily create a NinePatch graphic using a WYSIWYG editor

4emulator

This tools let you test your applications without using a physical device

5mksdcard

Helps you create a disk image (external sdcard storage) that you can use with the emulator

6proguard

Shrinks, optimizes, and obfuscates your code by removing unused code

7sqlite3

Lets you access the SQLite data files created and used by Android applications

8traceview

Provides a graphical viewer for execution logs saved by your application

9Adb

Android Debug Bridge (adb) is a versatile command line tool that lets you communicate with an emulator instance or connected Android-powered device.

We will discuss three important tools here that are android,ddms and sqlite3.

Android

Android is a development tool that lets you perform these tasks:

  • Manage Android Virtual Devices (AVD)

  • Create and update Android projects

  • Update your sdk with new platform add-ons and documentation

DDMS

DDMS stands for Dalvik debug monitor server, that provide many services on the device. The service could include message formation, call spoofing, capturing screenshot, exploring internal threads and file systems e.t.c

Running DDMS

Android app to pc

From Android studio click on Tools>Android>Android device Monitor.

How it works

In android, each application runs in its own process and each process run in the virtual machine. Each VM exposes a unique port, that a debugger can attach to.

When DDMS starts, it connects to adb. When a device is connected, a VM monitoring service is created between adb and DDMS, which notifies DDMS when a VM on the device is started or terminated.

Making SMS

Making sms to emulator.we need to call telnet client and server as shown below

Now click on send button, and you will see an sms notification in the emulator window. It is shown below −

Making Call

In the DDMS, select the Emulator Control tab. In the emulator control tab , click on voice and then start typing the incoming number. It is shown in the picture below −

Now click on the call button to make a call to your emulator. It is shown below −

Now click on hangup in the Android studio window to terminate the call.

The fake sms and call can be viewed from the notification by just dragging the notification window to the center using mouse. It is shown below −

Capturing ScreenShot

You can also capture screenshot of your emulator. For this look for the camera icon on the right side under Devices tab. Just point your mouse over it and select it.

As soon as you select it , it will start the screen capturing process and will capture whatever screen of the emulator currently active. It is shown below −

The eclipse orientation can be changed using Ctrl + F11 key. Now you can save the image or rotate it and then select done to exit the screen capture dialog.

Sqlite3

Sqlite3 is a command line program which is used to manage the SQLite databases created by Android applications. The tool also allow us to execute the SQL statements on the fly.

There are two way through which you can use SQlite , either from remote shell or you can use locally.

Use Sqlite3 from a remote shell.

Enter a remote shell by entering the following command −

From a remote shell, start the sqlite3 tool by entering the following command −

Once you invoke sqlite3, you can issue sqlite3 commands in the shell. To exit and return to the adb remote shell, enter exit or press CTRL+D.

Using Sqlite3 directly

Copy a database file from your device to your host machine.

Start the sqlite3 tool from the /tools directory, specifying the database file −

Platform tools

The platform tools are customized to support the features of the latest android platform.

The platform tools are typically updated every time you install a new SDK platform. Each update of the platform tools is backward compatible with older platforms.

Some of the platform tools are listd below −
