Problems making calls with platformRequest("tel:666666666")


I've developed an application in J2ME with Netbeans. It runs Ok in all phones, but when i recompiled the .jar to obtain the .cod, the application runs ok in Blackberry (8120) excepts for a command that i called "Call" that runs:

private void callMaker() {

boolean mustExit;

 try {

      mustExit = this.platformRequest("tel:902222222");

      if (mustExit) {


} catch (Exception e) {/*e.printStackTrace();*/}

 I did have a smilar problem when calling the platformrequest from a thread (MIDlet based application).



you may try the following:


// Explaination: added cause the platformRequest did thrown an exception
// "RuntimeException: pushModalScreen called by a non-event thread"
// when called from a thread (cause is not the BB event thread)
new Runnable() {
public void run() {
try {
//We assume that BB Device don't need to close the Midlet in order to process a phone call / web browser.

} catch (Exception ex) {


MUST be called from the main thread (I call it from the canvas.repaint) (you may want to implement a queue system)



oh, and this could be useful:


DoPlatformRequest(rqt, !net.rim.device.api.system.Application.isEventDispatchThread()); /* net.rim.device.api.system.Application.isEventDispatchThread() == true * from thread Draw/KeyPressed, but not from other thread. */




hopes this helps,
