+Приложение для перехвата и анализа входящих СМС
+================================================
+Приложение состоит из одного экрана, где можно указать номер телефона, смс от которого необходимо перехватывать.
+
+![Screen_example](arts/screen1.jpg)
+
+**Как импортировать в свой проект?**
+
+Вся логика происходит в классе SmsListener.</br>
+Его необходимо скопировать и добавить в AndroidManifest.xml своего проекта
+Также на устройствах начиная от 6.0 для чтения входящих смс необходимо получить разрешение от пользователя
+на чтение смс `Manifest.permission.RECEIVE_SMS`.
