Android dialer application

Question

I am figuring out a way to replace the default dialer application from my custom dialer application, but I am not getting how to achieve this.

Here is what I want

• Create a custom dialer UI
• My application is called whenever call button hardware or that one in Android is pressed
• The application can also be called from the contact screen

I am referring to public static final String ACTION_DIAL.

1. Create a simple Android application (our dialer). To actually call someone, you just need that method:

   private void performDial(String numberString) {     if (!numberString.equals("")) {        Uri number = Uri.parse("tel:" + numberString);        Intent dial = new Intent(Intent.ACTION_CALL, number);        startActivity(dial);     } } 

2. Give your application permission to call in AndroidManifest

   <uses-permission android:name="android.permission.CALL_PHONE" /> 

3. Set in AndroidManifest intention that says to your phone to use your app when need a dialer

When someone press the call button:

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

When someone fire an URI:

    <intent-filter>         <action android:name="android.intent.action.VIEW" />         <action android:name="android.intent.action.DIAL" />         <category android:name="android.intent.category.DEFAULT" />         <category android:name="android.intent.category.BROWSABLE" />         <data android:scheme="tel" />     </intent-filter>
