J2ME Google Maps API access problem

[elaltaico]

I use J2ME Google Maps API to write coordinates of a location and see it on a image file. Unfortunately, I got this error when I compile my application:


java.lang.SecurityException: Application not authorized to access the restricted API
at com.sun.midp.security.SecurityToken.checkIfPermissionAllowed(SecurityToken.java:170)

When I check my password that I took from Gmail and try it on an HTML i can see the image. But it does not work when I wrote the password in the code. What should I do to breach the security? Thank you in advance.

This is nothing to do with the Google Maps API.

You have written a class GoogleMaps, correct? Take a look in the getForm() method... you have the expression:

new GoogleMaps()

GoogleMaps extends MIDlet. It is an application. Only the application manager can create an instance of a MIDlet. If you need to access the instance of GoogleMaps, it can be referenced as "this" in any instance (non-static) method.

Yes I have new GoogleMaps() expression. You can see my code inside getForm() below:

public Form getForm() {
if (form == null) {
// write pre-init user code here
form = new Form("form", new Item[] { getImageItem() });
// write post-init user code here
GoogleMaps gMap = new GoogleMaps("ABQIAAAA7qdeVaJ6yIEBXYN8wiXCghSokdr2Whc27jI3E0XpKCOM9q-hAxQein5A9oOZcaooUSTtzJoPQmgtQA");
try {
Image map = gMap.retrieveStaticImage(320, 240, 41.008822, 28.981542, 8, "png32");
} catch (IOException ex) {
ex.printStackTrace();
}



}
return form;
}

I have been trying to fix the problem for 2 days and I believe the problem should be something except code but I do not know. Thank you in advance.

are you sure about this line :

form = new Form("form", new Item[] { getImageItem() });

whats that method ur calling getImageItem() ?

[grahamhughes]

Your class GoogleMaps is a subclass of MIDlet. You cannot create an instance of it.

This line of code cannot be executed:

GoogleMaps gMap = new GoogleMaps("ABQIAAAA7qdeVaJ6yIEBXYN8wiXCghSokdr2Whc27jI3E0XpKCOM9q-hAxQein5A9oOZcaooUSTtzJoPQmgtQA");

You are not permitted to create an instance of this class, because it is the MIDlet class.

Restructure your code, so that the mapping functionality is in a separate class, not in the MIDlet class.

Thank you grahamhughes. As you told me, I had to specify GoogleMaps functions and methods in a different class. I created a different GoogleMaps() class, that's why I got Security Exception. I created GoogleMaps class and I invoked GoogleMaps from VisualMidlets class and it worked very well. Thank you all.
