To implement outgoing calls in your custom application, you can use Android’s TelephonyManager and Intent classes. First of all, request the necessary permissions in your AndroidManifest.xml. Then, use TelephonyManager to check if the device is capable of making calls. If yes, use Intent.ACTION_CALL to initiate an outgoing call with the desired phone number. Also, ensure you handle the appropriate permissions and runtime checks to avoid issues.
