No black edge on the color plane

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Build AmbilWarna on a 64 BIT windows environment
2. Run Ambilwarna color picker on a tablet (the bug only manifests on tablets, 
we reproduced it on Nexus tab and Prestigio Multipad)

What is the expected output? What do you see instead?
The expected output is the color plane with black on the bottom edge. The 
manifestation of the bug is, that there is no dark gradient on the color plane, 
there is just white on the left and solid color on the right, the color gets no 
darker towards the bottom of the color plane.

What version of the product are you using? On what operating system?
Tested on Nexus tab and Prestigio Multipad PMP5197D ultra, built on 64bit 
windows 7. If AmbilWarna is built on Linux or 32 bit windows, the bug does not 
pop out.

Please provide any additional information below.

As far as I know, the bug is present on Android 3.0 to 3.2 if the hardware 
acceleration is enabled. However, since layerType attribute is already used on 
the color selector square, it should work correctly. I don't know how the app 
build on a different machine could make the result different when run on a same 
device.

4.2.2. Screenshot is attached. If I can help...

I solved that issue with the following code:

@TargetApi(Build.VERSION_CODES.HONEYCOMB)
private void checkVersion(){
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB) {
        setLayerType(View.LAYER_TYPE_SOFTWARE, null);
    }
}
