Sensitive APIs

In the Nokia Asha software platform 1.0, the MIDlet developer should create a new thread to call the sensitive APIs, otherwise the Java permission dialog will block the event queue thread.

Therefore, for example, the method call in handling sendCommand should be as follows:

public void commandAction(Command command, Displayable d) {
    if (command == sendCommand) {
        new Thread() {
            public void run() {
                wmaEngine.send(numberTextField.getString(), messageTextField.getString());
            }
        }.start();
        else if (command == exitCommand) {
            midlet.notifyDestroyed();
        }
    }
}

Sensitive API calls

The problem occurs, when the API call is in commandAction() method, not when it is, for example, in the MIDlet constructor.

public void startApp() {
    form = new Form("Security prompt test");

    ....

    httpConnector = new HTTPConnector(this);
    httpConnector.openHTTPConnection();	// No problems
}

public void commandAction(Command c, Displayable d) {
    if (c == exitCommand) this.notifyDestroyed();
    if (c == testCommand) {
        httpConnector = new HTTPConnector(this);
        httpConnector.openHTTPConnection();	// Problem exists here
    }
}
