How to open File from sdcard in Android

Just open your main XML file and paste below code:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/ll"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="vertical" >

    <Button
        android:id="@+id/button1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="My BOOK"
        android:onClick="book"/>

</LinearLayout>


Now open your java file and paste below code:


package sel.listG; //package name

import java.io.File;
import android.net.Uri;
import android.os.Bundle;
import android.view.View;
import android.widget.Toast;
import android.app.Activity;
import android.content.ActivityNotFoundException;
import android.content.Intent;

public class MainActivity extends Activity  {


      @Override
      protected void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            setContentView(R.layout.activity_main);
                       
           
      }
      public void book(View v)
      {
//your pdf file path
            File file=new File("/sdcard/anna.pdf");
            if(file.exists())
            {
                  Intent i= new Intent(Intent.ACTION_VIEW);
//set pdf to doc if you want to open doc
                  i.setDataAndType(Uri.fromFile(file), "application/pdf");
                  i.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
                  try
                  {
                  startActivity(i);
                  }
                  catch(ActivityNotFoundException e)
                  {
//if pdf reader not found than open browser to download pdf reader
                        Intent i1=new Intent(Intent.ACTION_VIEW, Uri.parse("https://play.google.com/store/apps/details?id=com.adobe.reader&hl=en"));
                        startActivity(i1);
                  }
            }
            else
            {
//if pdf not found on given location
                  Toast.makeText(getApplicationContext(), "anna.pdf not found", Toast.LENGTH_LONG).show();
            }
      }
}
 

Now run your code....
