ClassCastException: com.android.internal.telephony.PhoneProxy

I'm newbie in Android.

I'm programing Instrumentation Tests for SIM ToolKit (STK)

I need to use CommandsInterface which is available only in PhoneBase Interface. Once I have a Phone i'd like to use the following line:

private Phone   mPhone;
private Context    mContext;
private Handler    mHandler;
private CommandsInterface            mCmdIf;
private PhoneBase    mPhoneBase;

mPhoneBase = ((PhoneBase)mPhone);  <==== uncaught exception 
mCmdIf = mPhoneBase.mCM;

It compiled successfully, however gives uncaught exception (group=0x4001b188) Please advice how to overcome this issue. Thanks In Advance Micha

You can't use PhoneBase directly because it's an internal in android and not visible in the SDK. You can check your exception msg using logcat.

From the source code:

/**
 * (<em>Not for SDK use</em>) 
 * A base implementation for the com.android.internal.telephony.Phone interface.
 * 
 * Note that implementations of Phone.java are expected to be used
 * from a single application thread. This should be the same thread that
 * originally called PhoneFactory to obtain the interface.
 *
 *  {@hide}
 *
 */

I don't know what mCM is, but I guess you can get that information from TelephonyManager. You can get it doing

Context.getSystemService(Context.TELEPHONY_SERVICE);
