I update SDK from 1.2.5 to 1.2.6 and Comm.makeJsonRequest() stopped working. Without errors. A program stops on this method and is not called callback method.
In your other thread I asked about the size and complexity of the data you are getting back. Is this one in the sim or on a watch? If on a watch, which watch (fw Version too)
I develop my app on sdk 1.2.5 and Comm.makeJsonRequest() work fine without errors. Then I download sdk 1.2.6, change PATH to this bin directory and change path to sdk 1.2.6 in eclipse settings. After that Comm.makeJsonRequest() not work. I do not change my code. Only compile with new sdk.
