How can I access Android private API's which doesn't exposed in TelephonyManager?

I intend to write tests related to the Phone and Direct SIM write.

What are the alternatives in case the required APIs aren't exposed in TelephonyManager but exist as private APIs in PhoneBase.java, PhoneFactory.java or CommandInterface.java?

Specifically, my questions are:

  1. What is the "replacement" for: PhoneFactory.getDefaultPhone()?
  2. What is the alternative in order to access the CommandsInterface (e.g.: CommandsInterface mCmdIf = ((PhoneBase)mPhone).mCM)?

Thanks in advance,
Micha

You can use java reflection.

Here is how I accessed methods of com.android.internal.telephony.ITelephony class to block an incoming call ...

private void endCall() throws Exception {
      TelephonyManager tm = (TelephonyManager) context.getSystemService(Context.TELEPHONY_SERVICE);

      Class<?> c = Class.forName(tm.getClass().getName());
      Method m = c.getDeclaredMethod("getITelephony");
      m.setAccessible(true);
      ITelephony telephonyService = (ITelephony) m.invoke(tm);

      telephonyService.silenceRinger();
      telephonyService.endCall();
      Toast.makeText(context, "Call Ended !", Toast.LENGTH_SHORT).show();
}
