This is the simple code on how to detect the sd card if present or not using code.


This is the MainActivity.java

import android.os.Bundle;
import android.os.Environment;
import android.app.Activity;
import android.view.Menu;
import android.widget.TextView;

public class MainActivity extends Activity {

 @Override
 protected void onCreate(Bundle savedInstanceState) {
  super.onCreate(savedInstanceState);
  setContentView(R.layout.activity_main);
  
  TextView state = (TextView) findViewById(R.id.sdcardstatus);
  if(Environment.getExternalStorageState().equals(Environment.MEDIA_MOUNTED)) {
   state.setText("SD card is present");
  } else {
   state.setText("SD card is not present");
  }
 }
}

The activity_main.xml
