pen sdk SpenSurfaceView initiate androidruntime error

Question

I'm trying to use the samsung spen sdk pen-v5.1.0_full.aar . The .aar file is put under /libs and added to the dependencies in build.gradle file.

I can initiate the spen fine (from com.samsung.android.sdk.pen.Spen ),

I can also initiate a SpenPenDetachmentListener (from com.samsung.android.sdk.pen.engine.SpenPenDetachmentListener ),

however, when initiating SpenSurfaceView (from com.samsung.android.sdk.pen.engine.SpenSurfaceView ), I get an AndroidRunTime error:

02-11 16:30:03.921 25242 25242 E art     : No implementation found for boolean com.samsung.android.sdk.pen.engine.SpenGLInView.Native_isSupported() (tried Java_com_samsung_android_sdk_pen_engine_SpenGLInView_Native_1isSupported and Java_com_samsung_android_sdk_pen_engine_SpenGLInView_Native_1isSupported__)

I suspect that it's something I did wrong with import / using the .aar sdk, yet I don't understand why the Spen and the PenDetachmentListener can initiate fine yet the SpenSurfaceView not.

The apk compiles OK and would only crash when something tries to initiate the SpenSurfaceView.

Answer 1

It turned out that, SpenSurfaceView expect that Spen is initiated. After initiating Spen first, SpenSurfaceView is initiating fine.

Answer 2

I am developing an app with "pen-v4.1.1_full" version. Can you send me the files if I want to? I want to test - pen-v5.1.0_full.aar - sdk.1.0.1.jar I hope to receive it. Thank you.
