Project tango Never called the OnXYZijAvailable Callback

Question

My Project tango has some problems.

1st. The OnXYZijAvailable callback is never called. So sample code(point cloud) from github is not worked. (Point count always zero)

2nd. The back camera(RGB-IR) is seems always gray scale. How can I see color mode?

I guess back camera is broken or something wrong. Right??

Try the following:

1. restart the device. Google tango core is still very unstable.
2. make sure that the samples you're working with are aligned to the tango core version(check it on the samples your using Tags tab on github).

3. make sure that when you're configure the Tango object you're adding the depth perception like this:

   config.putBoolean(TangoConfig.KEY_BOOLEAN_DEPTH, true); // for getting point cloud
   mTango.connect(config);
   

4. about your grey-scale camera(which is very strange behaviour). Make sure you're adding color camera configuration like this:

   config.putBoolean(TangoConfig.KEY_BOOLEAN_COLORCAMERA, true);
   

5. make sure to add the dependency on the tango core also in the Manifest inside the application node(I totally missed it):

    <uses-library
       android:name="com.projecttango.libtango_device"
       android:required="true" />
