Using this should do the trick instead of the test block below:
mHeading = MathUtils.mod(computeTrueNorht(magneticHeading) - ARM_DISPLACEMENT_DEGREES, 360.0f);

Also, please make sure to follow Android's coding style standard:
https://source.android.com/source/code-style.html

Specifically, use spaces instead of tabs and keep the lines below 100 characters.


// The user was looking ~ due north (0 - 5.999 degrees)
if(mHeading < 0) {
mHeading = 360.0 + mHeading;
}

notifyOrientationChanged();
