1.1. Product Summary and Functions

The BT-2000/2200 is a smart headset for business use. The same optical see-through

technology as the consumer orientated MOVERIO BT-200 has been adopted. This allows

information to be displayed across a wide viewing area while keeping eye movement to a

minimum, thereby reducing fatigue and making it suitable for use at work. This also allows you

to view your surroundings while projecting an image, which adds an aspect of safety.

The weight of the product is supported by the entire head, allowing you to work for long periods

of time without feeling fatigued. You can work while checking images in a hands-free

environment.

2.6. Including the SDK provided by EPSON

2.6.1. Cautions for using SDK provided by EPSON

Please make sure to confirm the version of SDK provided by EPSON and the version of system

software inside BT-2000.

If the version of SDK provided by EPSON used for Apps development and the version of system

software is not matching, due to the difference of API included, developed Apps may not operate.

※User using system software version R1.0.4

When updating OS from R1.0.4 to R1.2.1 or later, adding callback API process which is newly

added is required.

This phenomenon may occur in below Apps.

・Apps using Voice command class(VoiceCommandClientCallbacks)

If it happens, please solve by below procedure.

１） Change the SDK of Apps development environment to SDK that matching system

software version.

２） Revise the source code according to SDK and re-build.


21

2.6.2. How to use SDK provided by EPSON

The following procedures assume app development in Android Studio.

1) Display Project View of Android Studio, and then create “libs” folder from

[File]-[New]-[Directory].

2) C:\Users\<user name>\AndroidStudioProjects\<application name>\app\libs will be

created, and put H725Ctrl.jar to this folder.

（When created project folder is C:\Users\<user name>\AndroidStudioProjects）

※ Explanation from now on is based on that project is at C:\Users\<user

name>\AndroidStudioProjects\<application name>.

3) Press Sync Project with Gradle Files button where it is above of AndroidStudio, reflect

Gradle change to the project.

4) Open build.gradle(Project: <application name>) in the left window of AndroidStudio,

and then edit as below.

allprojects { repositories { jcenter() } gradle.projectsEvaluated { tasks.withType(JavaCompile) { options.compilerArgs.add('-Xbootclasspath/p:C:/Users/<user name>/AndroidStudioProjects/<application name>/app/libs/H725Ctrl.jar') } }

}


22

5) Once, run Clean Project from Build items of AndroidStudio.

SDK settings are completed by above.

On edit display, EPSON original API like getSupportedEpsonCameraModes() are still not solved,

but please ignore and run app, and install application to the equipment. Unsolved method will

operate normally.


23

2.6.3. To solve unsolved situation by Android Studio

By below method, you can solve the unsolved situation temporary and use code completion

function.

1) Open C:\Users\<user name>\AndroidStudioProjects\<application name>\app\app.iml

2) Move line of

<orderEntry type="library" exported="" name="H725Ctrl" level="project" />

to the line above

<orderEntry type="jdk" jdkName="Android API 23 Platform" jdkType="Android SDK"/>

This will increase the priority of H725Ctrl.jar in AndroidStudio, and can solve the unsolved

situation temporary and use code completion function.

■Limited items

Due to AndroidStudio specification, after running like rebuild and update gradle contents,

app.iml will be updated too and EPSON original API will return to unsolved situation. Please

proceed above 1), 2) again. Run after build will not be affected.
