In this tutorial, I will be demonstrating how to build an App with a Functionality of Calling And Sending Message without Using Phones dialerPad Or Message Inbox.
Below is screenshot of final output
- Create a new project by going to File ⇒ New Android Project. Fill all the details and name your activity as MainActivity
- Once the project is created open your activity_main.xml file and Add Below Code
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
tools:context="com.targetandroid.info.smscallapp.MainActivity">
<EditText
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:hint="Enter No."
android:id="@+id/etno_sms"
android:inputType="phone"
android:gravity="center"
/>
<EditText
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:hint="enter message"
android:lines="4"
android:padding="16dp"
android:id="@+id/etmessage_sms"/>
<Button
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="Send Message"
android:id="@+id/bt_message"
/>
<Button
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="Call"
android:id="@+id/bt_call"
/>
</LinearLayout>
3. Open AndroidManifest.xml
and Add this Two Permission Above Application Tag
<uses-permission android:name="android.permission.CALL_PHONE" /> <uses-permission android:name="android.permission.SEND_SMS" />
4. Now Finally Open MainActivity.java and Copy this Part of Code

} catch (Exception e) {

}
}
@Override

case MY_PERMISSION_SMS:
