Fixed api compatibility issues:

Fixed api compatibility issues:

android:minSdkVersion="8"
android:targetSdkVersion="19"

However,
TargetApi wasn't introduced until api level 16,
which won't work with api level 8 as above.

Same with:
Build.VERSION_CODES.HONEYCOMB added in api level 11
View.LAYER_TYPE_SOFTWARE added in api level 11
Replaced them with their constant values instead.

I have verified that it works on api level 14. It won't compile
otherwise.

Finally:
readRanges() never uses its input parameters in:
private void readRanges(final Resources res, final int rangesId, final int colorsId)

    if (rangesId > 0 && colorsId > 0) {
        final String[] ranges = res.getStringArray(R.array.ranges);
        final String[] colors = res.getStringArray(R.array.rangeColors)
        ...

Changed it so that it uses rangesId and colorsId instead.

I have tried this as an apklib an it workds. It was incorrect as
it was before, because it wouldn't reference the correct resources
if I remember correctly.
