I am trying to download and open a PDF file inside android application i.e. without using any other application(pdf viewer,etc) installed on phone.
Please tell me is it possible??
So far What I have done is :
PdfViewerActivity.java
public class PDFViewerActivity extends Activity { private Button mDownLoadPdf; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.pdfviewer_activity); } public void downloadPDF(View v) { // new DownloadFile().execute("http://maven.apache.org/maven-1.x/maven.pdf", "maven.pdf"); new DownloadFile().execute("http://dev-hop-docs.seechangehealth.com/SitePages/PDFLoader.aspx?test=abc"); Toast.makeText(this,"Download finished,Viewing PDF...",Toast.LENGTH_SHORT).show(); view(); } public void view() { File pdfFile = new File(Environment.getExternalStorageDirectory() + "/testthreepdf/" + "privacy notice.pdf"); // -> filename = maven.pdf Uri path = Uri.fromFile(pdfFile); Intent pdfIntent = new Intent(Intent.ACTION_VIEW); pdfIntent.setDataAndType(path, "application/pdf"); pdfIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP); try{ startActivity(pdfIntent); }catch(ActivityNotFoundException e){ Toast.makeText(PDFViewerActivity.this, "No Application available to view PDF", Toast.LENGTH_SHORT).show(); } } private class DownloadFile extends AsyncTask<String, Void, Void> { @Override protected Void doInBackground(String... strings) { String fileUrl = strings[0]; // -> http://maven.apache.org/maven-1.x/maven.pdf // String fileName = strings[1]; // -> maven.pdf String fileName = "privacy notice.pdf"; String extStorageDirectory = Environment.getExternalStorageDirectory().toString(); File folder = new File(extStorageDirectory, "testthreepdf"); folder.mkdir(); File pdfFile = new File(folder, fileName); try{ pdfFile.createNewFile(); }catch (IOException e){ e.printStackTrace(); } FileLoader.downloadFile(fileUrl, pdfFile); return null; } } } And this is my FileLoader.java
public class FileLoader { private static final int MEGABYTE = 1024 * 1024; public static void downloadFile(String fileUrl, File directory){ try { URL url = new URL(fileUrl); HttpURLConnection urlConnection = (HttpURLConnection)url.openConnection(); urlConnection.setRequestMethod("GET"); // urlConnection.setDoOutput(true); // urlConnection.connect(); InputStream inputStream = urlConnection.getInputStream(); FileOutputStream fileOutputStream = new FileOutputStream(directory); int totalSize = urlConnection.getContentLength(); byte[] buffer = new byte[MEGABYTE]; int bufferLength = 0; while((bufferLength = inputStream.read(buffer))>0 ){ fileOutputStream.write(buffer, 0, bufferLength); } fileOutputStream.close(); } catch (FileNotFoundException e) { e.printStackTrace(); } catch (MalformedURLException e) { e.printStackTrace(); } catch (IOException e) { e.printStackTrace(); } } } Using the above code , I am getting following error :
Invalid PDF Format.
But when i paste this webservice url on pc browser it opens a pdf.
Please tell me what I have done wrong. Or is there any other way to achieve it.
