3.2 Installing JDK
Java SE JDK can be downloaded from the Java site. Visit the site and download the Java SE JDK package
corresponding to your Windows platform.
The URL and contents of the Java site may differ from the contents described in this document due to the
update of the site. When downloading the JDK, please access the Java site via the search engine etc. and
follow the description of the site.
In the following example, "jdk-8u121-windows-i586.exe" (64 bit) is downloaded.
For the 32 bit Windows, 32 bit version of JDK must be needed.
※ Because JDK is frequently updated, it's better to install the latest version at that time.
10
Execute the downloaded file with administrator privileges. Basically, it is not needed to change the value
from default.
11
12
3.3 Installing Android Studio
Android Studio can be downloaded from Android site of Google.
http://developer.android.com/sdk/index.html
Agree to the “Terms of Conditions”, then start downloading.
Once executing the downloaded file, follow the instructions to proceed the installation.
13
During installation, you will be prompted to specify the installation destination by the dialog below. The
"Android SDK Installation Location" on the figure below is also necessary when installing the USB driver,
it's better to take a note.
When the dialog shown below is displayed, installation of Android Studio is completed.
14
3.4 Downloading Android SDK and USB driver
Launch Android Studio, and chose "SDK Manager" from Configure tab.
Then, select “SDK Tools” tab and check "Google USB Driver".
15
Once agree to the “License Agreement”, then press “OK” to start installation.
The downloaded files are stored under "Android SDK Installation Location" that you noted in "3.3
Installing Android Studio (p.13) ".
The USB driver is stored in "extras¥google¥usb_driver" under "Android SDK Installation Location".
16
3.5 Installing and Updating Device Library (AAR)
This chapter explains how to register the device library and its help file to Android Studio project.
3.5.1 Preparations
Device Library ( AAR ) and its help files ( Javadoc ) are needed to be registered to the each project via
Android Studio. Therefore, the method described here is necessary every time when creating new project
that uses the device library.
The following chapter explains the procedure for registering the device library and its help files to the
project. It is better to copy the DeviceLibrary and its help files from the IT-G400 Basic Development Kit to
the local folder beforehand.
3.5.2 Registering DeviceLibrary ( AAR )
Once open the project from the Android Studio, open the "New Module" dialog with [File] → [New] →
New Module.
17
On the dialog shown below, select "Import .JAR/.AAR Package" and proceed with "Next".
Press the
of "File name" and select the DeviceLibrary (AAR) you copied beforehand.
By the above, the registration of the device library to the project was completed. You can see that the AAR
file name has been added to the Android Studio Project tree.
18
19
3.5.3 Dependency check of DeviceLibrary ( AAR )
Project Structure...
The registration of the device library was completed with "3.5.2 Registering DeviceLibrary (p.17)".
However, somehow the dependency relationship of the DeviceLibrary to the project is not set correctly in
some cases.
If the dependency is not set correctly, "3.5.4 Registering Help files ( Javadoc ) (p.23)" can not be done
correctly, in that case follow the explanation in this section.
First, select "Project Structure ..." from File menu.
Open the "Dependencie" tab and check if "DeviceLibrary" (red frame in the figure below) exists. If it exists,
subsequent operations are unnecessary.
If it does not exist, tap "+ button" at right end and select "Module dependency".
20
Confirm that "DeviceLibrary" is displayed as shown below and tap "OK".
By the above, "DeviceLibrary" has been added to the tab of "Dependencies".
21
22
3.5.4 Registering Help files ( Javadoc )
<JAVADOC>
</JAVADOC>
This section explains how to enable pop-up help (pops up help message when you move the cursor to the
function name) of Device Library.
First, associate Javadoc which is the help file of Device Libraries to Device Library registered to Android
Studio.
The Javadoc file can be placed anywhere as long as it can be referenced on the PC. It assumes that it is
placed in the "docs/DeviceLibrary" folder here.
When registration of the device library is completed, a xml file whose name is same as the library is
automatically created under the “". Idea" folder. At moment, the item "<JAVADOC>" in this xml file has
not been set. Specify the location of the javadoc file (folder path with index.html) in this item
"<JAVADOC>".
By the above, the registration of the help file was completed.
Next, enable "Quick documentation on mouse move" which is the function of Android Studio.
23
Select "Settings ..." from File menu of Android Studio.
Settings
Show quick documentationon mouse move.
Show quick documentation
on mouse move.
Next, check a box of "Show quick documentation on mouse move".
Now, if you hover the mouse cursor over the function name, help of the function will be poped up.
24
3.5.5 Updating of DeviceLibrary ( AAR )
In order to update the device control library registered in the project of Android Studio (exchange to the
new version), once you need to unregister (unassociate) them and register new one.
This section explains how to unregister (unassociate) them from the project.
(1) Unassociate Library ( AAR )
Open your project in Android Studio and select [File] -> [Project Structure ...]. Select "app" from
"Modules" in the left frame and open the "Dependencies" tab. Select DeviceLibrary and press the right
“-“ button to cancel the association.
(2) Unregister Library ( AAR )
Next, select "DeviceLibrary" from "Modules" in the left frame and tap "- button" in the upper left.
25
A dialog to confirm deletion of DeviceLibrary appears, so tap [Yes].
By the above, Device Library was unregistered. Follow "3.5Installing and Updating Device Library(p.17)"
to register the new Device Library.
26
3.6 How to use the DeviceLibrary ( AAR )
To use an AAR file, just like jar, it is needed to inport it in order to create class object.
If a class that has not been imported is used, popup message as shown below is comes.
27
4. Application development and debug
In order to develop / debug applications using IT-G400, the following preparation is necessary.
(1) Enable USB debugging (ADB connection) of IT-G400.
(2) Install IT-G400 USB driver to your PC.
(3) Set PATH to the debug tools on your PC.
These steps are described below.
4.1 Enabling USB debugging
Since USB debugging is a function for developers, you first need to activate the Developer
options by the following procedure.
Open [Settings] → [About phone] and tap "Build number" on the bottom line seven times,
[Developer options] is added above [About phone].
28
Tap [Developer options] and enable "USB debugging" on the opened screen.
4.2 Installing USB driver
Install the USB driver for connecting the IT-G400 and PC with the ADB (Android Debug Bridge) protocol.
Files necessary for installation are downloaded as described in "3.4 Downloading Android SDK and USB
driver (p.15)”.
Connect the IT-G400 to a PC using a USB cable or a USB cradle. Then, open the Device Manager by
[Control Panel] → [Hardware and Sound] → [Device Manager].
29
In the Device Manager, “Android” is displayed as an unknown device as shown below.
By right-click the red frame (“Android”) in the above figure, displays its properties, and press [Update
Driver].
When the dialog below is displayed, press "Let me pick from a list of drivers on my computer " at the
bottom. In the driver list, with "Show all devices" is highlighted and press [Next].
30
When you click [Hard Disk…] in the displayed dialog, a dialog box for specifying the location of the driver
opens, so click [Browse…] to open the file dialog box. In the file dialog box, search for
“extras¥google¥usb_driver¥android_winusb.inf” under the “Android SDK Installation Location" that you
took note in “3.4 Downloading Android SDK and USB driver (p.15)” and specify it.
The following driver selection screen will appear. Select "Android Composite ADB Interface" and press
[Next]. Answer "Yes" to "Driver Update Warning" and press "Install" of "Windows Security" dialog.
By the above, the installation of the USB driver for ADB protocol was completed.
31
4.3 Settings for ADB ( Android Debug Bridge )
In order to use Android SDK tools such as adb from the command prompt, it is needed to add the path to
Android SDK to the system environment variable. Add the following two paths.
The "tools" folder under "Android SDK Installation Location" that you took note.
The "platform-tools" folder under "Android SDK Installation Location".
In the above example, the path to add is as follows.
