In this post we will learn how to connect and configure Android Device (Smartphone etc.) with Android Studio. After that we will run a simple Hello World Program.
 

Pre-requisites:


1) Android Studio installed on your PC (Unix or Windows). You can learn how to install it here .

2) A basic knowledge of Android lifecycle and different classes & functions used in Android Studio.

Follow following steps for connecting smartphone with Android Studio:

First we need to enable Developer options on Android device.

Go to Settings of the Android Device and then System Settings as shown below:

Click on About Phone (In some devices it is About Device). Following screen will be opened:

For Android version higher than 4.4, developer option is hidden. In the above window there will be a Build number.
You need to hit this build number 7 times. It is common for all android devices. Now go back to settings again. You will see developer options as shown below:

Select developer options and then select USB debugging option. Connect your Android device with Android Studio through micro USB wire. Select photo transfer (PTP) option.
 

Now open Device Monitor in Android Studio and you will be able to see device connected.

So we have successfully connected and configured android device. Now let’s run a Hello World App on our configured device.

Creating new project


Please follow following steps:

  1. Open Android Studio and make a new project with name “Android Device” and company domain application.example.com (I used my company domain i.e androidtutorialpoint.com. Similarly you can use yours).
  2. Click Next and choose android version Lollipop. Again Click Next and Choose Blank Activity.
  3. Leave all things remaining same and Click Finish.
Now you can see MainActivity.javacontent_main.xml and strings.xml. If you are not able to see them then click on the left window where these files can easily be located as shown in following figure:
