Post message to facebook wall from android fb sdk always error

The fix is:

if (parameters.get(key) instanceof byte[]) {

instead of

if (parameters.getByteArray(key) != null) {

on line 63 of Util.java.

And

if (params.get(key) instanceof byte[]) {

instead of

if (params.getByteArray(key) != null) {

on line 155 of Util.java.

For some strange reason, on Samsung Nexus S (perhaps other devices too) it returns a String, not a byte[].
