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.makeDefa

Answer 1

Yes it can be instantiated. But you have to overcome a couple of hurdles:

• In your AndroidManifest.xml set

  android:sharedUserId="android.uid.phone"

  within the tag. This is required to prevent a SecurityException from being thrown when protected Intents are sent by the methods you may invoke (like android.intent.action.SIM_STATE_CHANGED).

• Set

  android:process="com.android.phone"

  in your tag. This is required to allow the invocation of getDefaultPhone() / makeDefaultPhone().

• To do all this your app must be signed with the system signature key.
