Answer 2

Intent callIntent = new Intent(Intent.ACTION_DIAL);
callIntent.setData(Uri.parse("tel:" + phoneNumber));
 if (ActivityCompat.checkSelfPermission(getActivity(), Manifest.permission.CALL_PHONE) != PackageManager.PERMISSION_GRANTED) {
                // TODO: Consider calling
                //    ActivityCompat#requestPermissions
                // here to request the missing permissions, and then overriding
                //   public void onRequestPermissionsResult(int requestCode, String[] permissions,
                //                                          int[] grantResults)
                // to handle the case where the user grants the permission. See the documentation
                // for ActivityCompat#requestPermissions for more details.
                return;
            }
startActivity(callIntent);

Also, you should register the custom dialscreen as follows in the manifest:

<application
android:icon="@drawable/ic_launcher"
android:label="@string/app_name" >
<activity
    android:name=".MyDialerApplication"
    android:label="@string/app_name" >

    <intent-filter android:priority="100" >
        <action android:name="android.intent.action.MAIN" />
         <action android:name="android.intent.action.DIAL" />
         <action android:name="android.intent.action.CALL_PRIVILEGED" />
        <category android:name="android.intent.category.DEFAULT" />
        <data android:scheme="tel" />

    </intent-filter>
</activity>
