Android dialer application
android, phone-call
Solution
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);
}
}
Give your application permission to call in AndroidManifest
<uses-permission android:name="android.permission.CALL_PHONE" />
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>
Problem
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.
