Can a telephony.Phone object be instantiated through the sdk?

Question

I am trying to get a phone object so that I can call and conference two numbers from within my application.

I have tried using the static PhoneFactory.makeDefaultPhones((Context)this) but have not had any luck.

String phoneFactoryName = "com.android.internal.telephony.PhoneFactory";
String phoneName = "com.android.internal.telephony.Phone";
Class phoneFactoryClass = Class.forName(phoneFactoryName);
Class phoneClass = Class.forName(phoneName);
Method getDefaultPhone = phoneFactoryClass.getMethod("getDefaultPhone");
Object phoneObject = getDefaultPhone.invoke(null);

Error - Caused by java.lang.RuntimeException: PhoneFactory.getDefaultPhone must be called from Looper thread

That is not possible from the SDK.

I have tried using the static PhoneFactory.makeDefaultPhones((Context)this) but have not had any luck.

That is not in the SDK. Please do not go past the bounds of the SDK.

That is because you are trying to do the thing-you're-not-supposed-to-be-doing from a background thread.

Answer 2

I call it from Activity.onCreate and I crashed several lines after your problem:

IllegalStateException("Default phones haven't been made yet!");

See the Android sources:

public static Phone getDefaultPhone() { if (sLooper != Looper.myLooper()) { throw new RuntimeException( "PhoneFactory.getDefaultPhone must be called from Looper thread"); }

    if (!sMadeDefaults) {
        throw new IllegalStateException("Default phones haven't been made yet!");
    }
   return sProxyPhone;
}

Al least we can answer or ignore calls =) let me copy-paste my post

OMG!!! YES, WE CAN DO THAT!!! I was going to kill myself after severe 24 hours of investigating and discovering... But I've found a "fresh" solution!

// "cheat" with Java reflection to gain access to TelephonyManager's ITelephony getter Class c = Class.forName(tm.getClass().getName()); Method m = c.getDeclaredMethod("getITelephony"); m.setAccessible(true); telephonyService = (ITelephony)m.invoke(tm);

all all all of hundreds of people who wants to develop their call-control software visit this start point http://www.google.com/codesearch/p?hl=en#zvQ8rp58BUs/trunk/phone/src/i4nc4mp/myLock/phone/CallPrompt.java&q=itelephony%20package:http://mylockforandroid%5C.googlecode%5C.com&d=0

there is a project. and there are important comments (and credits)

briefly: copy aidl file, add permissions to manifest, copy-paste source for telephony management )))

Some more info for you. AT commands you can send only if you are rooted. Than you can kill system process and send commands but you will need a reboot to allow your phone to receive and send calls =)))

I'm very hapy =) Now my Shake2MuteCall will get an update !
