Code calling Integer.divideUnsigned(value, 2) produces the following Dalvik bytecode:

000108: 1220               |0000: const/4 v0, #int 2
00010a: 7120 0200 0100     |0001: invoke-static {v1, v0}, Ljava/lang/Integer;.divideUnsigned:(II)I
000110: 0a01               |0004: move-result v1

Because of the use of a power of two, the code could be

000170: e100 0101          |0000: ushr-int/lit8 v0, v1, #int 1 // #01

For a teensy tiny savings in size and possibly an equally small performance bump (I haven't checked if Integer.divideUnsigned is an ART intrinsic).

The same is true for Long.divideUnsigned and ushr-long.
