How to delete an SMS from the inbox in Android programmatically?

This example demonstrates how do I delete an sms from inbox in Android programmatically.

Step 1 − Create a new project in Android Studio, go to File ⇒ New Project and fill all required details to create a new project.

Step 2 − Add the following code to res/layout/activity_main.xml.

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
   xmlns:tools="http://schemas.android.com/tools"
   android:layout_width="match_parent"
   android:layout_height="match_parent"
   tools:context=".MainActivity">
   <Button
      android:id="@+id/bt_delete"
      android:layout_width="wrap_content"
      android:layout_height="wrap_content"
      android:text="Delete SMS"
      android:layout_centerInParent="true" />
</RelativeLayout>

Step 3 − Add the following code to src/MainActivity.java

import android.content.Context;
import android.net.Uri;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.Toast;
public class MainActivity extends AppCompatActivity {
   private Context mContext;
   @Override
   protected void onCreate(Bundle savedInstanceState) {
      super.onCreate(savedInstanceState);
      setContentView(R.layout.activity_main);
      mContext = this;
      Button btn = (Button) findViewById(R.id.bt_delete);
      btn.setOnClickListener(new View.OnClickListener() {
         @Override
         public void onClick(View v) {
            if (deleteSMS()) {
               Toast.makeText(mContext, "Your message is deleted.", Toast.LENGTH_LONG).show();
            } else {
               Toast.makeText(mContext, "Sorry we can't delete messages.", Toast.LENGTH_LONG).show();
            }
         }
      });
   }
   private boolean deleteSMS() {
      boolean isDeleted = false;
      try {
         mContext.getContentResolver().delete(Uri.parse("content://sms/"), null, null);
         isDeleted = true;
      } catch (Exception ex) {
         isDeleted = false;
      }
      return isDeleted;
   }
}

Step 4 − Add the following code to androidManifest.xml

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android" package="app.com.sample">
   <uses-permission android:name="android.permission.READ_SMS" />
   <uses-permission android:name="android.permission.WRITE_SMS" />
   <application
      android:allowBackup="true"
      android:icon="@mipmap/ic_launcher"
      android:label="@string/app_name"
      android:roundIcon="@mipmap/ic_launcher_round"
      android:supportsRtl="true"
      android:theme="@style/AppTheme">
      <activity android:name=".MainActivity">
         <intent-filter>
            <action android:name="android.intent.action.MAIN" />
            <category android:name="android.intent.category.LAUNCHER" />
         </intent-filter>
      </activity>
   </application>
</manifest>

Let's try to run your application. I assume you have connected your actual Android Mobile device with your computer. To run the app from android studio, open one of your project's activity files and click Run  icon from the toolbar. Select your mobile device as an option and then check your mobile device which will display your default screen −
