How to detect if a Class/Package is available on the phone

Comments

This is the way things should work, unfortunately in practice many phone refuse to even run the midlet if any reference to a non supported API is included.

If any phone supports an api and if we don't know then this code will help to find api in phone.so it will help to intermediatery to find the api that a perticular MIDP and CLDC version supports.

We can use the dynamic instantiation method, like this:

boolean MMAPIAvailable;
try {
    // Try to instantiate a class using a string as the Class name
    // so, the SDK without the API can compile the application
    Class.forName("javax.microedition.media.Player").newInstance();
    // If the next code is executed, then the API is available
    MMAPIAvailable = true;
} catch ( ClassNotFoundException e) {
    MMAPIAvailable = false;
}
