onXyzIjAvailable() callback error

[leisipeisi]

Hi everyone,

I implemented an anonymous OnTangoUpdateListener() with the following code:

mPoseListener = new Tango.OnTangoUpdateListener() {
            @Override
            public void onPoseAvailable(TangoPoseData pose) {
                //do something
            }
            @Override
            public void onFrameAvailable(int cameraId) {
                //do something
            }
            @Override
            public void onXyzIjAvailable(TangoXyzIjData xyzIj) {
                //do something
            }
            @Override
            public void onTangoEvent(TangoEvent event) {
                // do something
            }
            @Override
            public void onPointCloudAvailable(TangoPointCloudData tangoPointCloudData) {
                // do something
            }
        };

When I run the code, every time new data is avaiable, the callbacks are called. OnPoseAvaiable() is working perfectly fine, but when a new XYZIj is avaiable, the app crashes with the following error:

JNI ERROR (app bug): attempt to pass an instance of com.google.atap.tangoservice.TangoPointCloudData as argument 1 to void com.projecttango.examples.java.motiontracking.MainActivity$1.onXyzIjAvailable(com.google.atap.tangoservice.TangoXyzIjData)

After this, numerous threads are aborted.

As far as a understand that message, the callback is called wrongly by the underlying service.

I got the code from here.

Does anybody encounter the same problem or has any suggestions on what to do to fix this?

Thanks in advance!

Hi, someone had the same problem here: https://plus.google.com/113842118597149774006/posts/baveVMxvF8g

According to the answer you have to do the following:

Instead of just: config.putBoolean(TangoConfig.KEY_BOOLEAN_DEPTH, true);

Now you need both:

config.putBoolean(TangoConfig.KEY_BOOLEAN_DEPTH, true);

config.putInt(TangoConfig.KEY_INT_DEPTH_MODE, TangoConfig.TANGO_DEPTH_MODE_POINT_CLOUD);

This will resolve your issue.

Thank you very much! This solution resolved my problem.
