How to make my own custom dialer in an Android phone

Question

In my application I add an intent so that the user can call:

str="tel:"+phoneArray[11];  
Intent intent = new Intent(Intent.ACTION_CALL);
intent.setData(Uri.parse(str));
startActivity(intent);

Then it calls from Android phone but I want to set up another custom dialer with a different look. What do need to do? I do not mean how to design the dialer, but only how to make a UI that will enter the number and execute a call.

Answer 1

Create an app that responds to Intent.ACTION_DIAL. In the AndroidManifest.xml you need to add the following to that Activity:

<intent-filter>
    <action android:name="android.intent.action.DIAL" />
    <category android:name="android.intent.category.DEFAULT" />
</intent-filter>

You can take the official phone app as reference. But be warned, it is no trivial task.

You can replace only the Dialer that way. The actual calling thing (what you see during calls) can't be changed.
