        } catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }

MainActivity.java

public class MainActivity extends Activity {
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        String extStorageDirectory = Environment.getExternalStorageDirectory()
                .toString();
        File folder = new File(extStorageDirectory, "pdf");
        folder.mkdir();
        File file = new File(folder, "Read.pdf");
        try {
            file.createNewFile();
        } catch (IOException e1) {
            e1.printStackTrace();
        }
        DownloadFile.downloadFile("http://14.140.41.194/monali/i.pdf",
                file);

        showPdf();
    }

     public void showPdf()
     {
         File file = new File(Environment.getExternalStorageDirectory()+"/pdf/Read.pdf");
         PackageManager packageManager = getPackageManager();
         Intent testIntent = new Intent(Intent.ACTION_VIEW);
         testIntent.setType("application/pdf");
         List list = packageManager.queryIntentActivities(testIntent, PackageManager.MATCH_DEFAULT_ONLY);
         Intent intent = new Intent();
         intent.setAction(Intent.ACTION_VIEW);
         Uri uri = Uri.fromFile(file);
         intent.setDataAndType(uri, "application/pdf");
         startActivity(intent);
     }
}

Can someone help me out where is the error in my code. ???

Answer 1

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

Intent intent = new Intent(Intent.ACTION_VIEW);
        intent.setDataAndType(
                Uri.parse("file://" + getFilesDir() + "/example.pdf"),
                "application/pdf");

        startActivity(intent);
    }
