7. Issues fixed in Basic function SDK version 1.2.2

These are the known issue in version 1.2.1.

  • When an application that uses the Basic function SDK is built with targetSdkVersion 34, the functionality cannot be used properly.
  • When launching camera for the second or subsequent times in Unity app, camera does not work.

8. Known issues in Basic function SDK version 1.2.2

  • When building an application that uses the camera function of Basic function SDK with "targetSdkVersion 28" or higher, may not work properly on Android 10 smartphone.
    Notes: At July 2020, the models that have been confirmed to cause this phenomenon are Sony smartphone Xperia 1 and Essential Products smartphone Essential Phone.
  • When using 8M video recording with the Basic function SDK's camera function, some smartphones may not save video files.
  • Repeatedly plugging and unplugging the headset while using the Unity plugin's camera function may cause the camera function to stop working.
  • Using Moverio Basic Function SDK and Controller Function SDK Together
    When developing an application that uses both the Moverio Basic Function SDK and the Moverio Controller Function SDK, special attention is required regarding the Android Gradle Plugin (AGP) version.Both SDKs currently use the same namespace (com.epson.moverio).
    Due to changes in namespace validation behavior in newer AGP versions, this may cause build errors depending on the AGP version used.

    Affected Environments

    Android Gradle Plugin Version Behavior
    AGP 8.x Build succeeds with default settings (warnings may be shown)
    AGP 9.x Build fails due to duplicate namespace validation

    Root Cause

    Starting with AGP 9.x, the default value of the Gradle property "android.uniquePackageNames" was changed to true.
    As a result, AGP enforces that all modules and libraries must have unique namespaces.
    Because both SDKs share the namespace com.epson.moverio, AGP 9.x treats this as a build error.

    Recommended Workaround (AGP 9.x)

    If you are using AGP 9.x, apply the following configuration to avoid the build error:

    1. Open the gradle.properties file at the project root.
    2. Add or update the following setting:
      android.uniquePackageNames=false

    With this setting:
    The build will succeed.
    Warnings related to duplicate namespaces may still be displayed.

    Limitations

    There are no plans to change the namespace structure of the Moverio SDKs.
    Developers must continue to use the above workaround when building with AGP 9.x.

    Important Notes for Developers

    Supporting newer Android OS versions generally requires newer AGP versions.
    If your application does not need to support the latest Android OS versions, it is possible to continue using an older AGP version or apply the workaround described above.
    However, using older AGP versions or lower Target SDK levels may cause your application to fail Google Play publishing requirements.
    Please carefully consider your distribution method and publishing strategy, especially for applications intended for distribution via Google Play.
