Leggere file PDF online utilizzando MuPDF

Question

Ho due problemi 1) Annotazione non funziona 2) Voglio leggere online in formato pdf

costruisco MuPDF utilizzando questo link http://mupdf.com/doc/how-to-build-mupdf-for-android

1) ottengo progetto MuPDF/platform/android Eseguo che l'annotazione app predefinita funzioni bene, ma creo quel progetto nel file della libreria che chiedono vogliono salvare ma l'annotazione non viene salvata.

2) Legge il file locale ma voglio anche leggere il file online. il mio codice Android

pdf = (TextView) findViewById(R.id.pdf); 
    onPdf = (TextView) findViewById(R.id.onPdf); 

    pdf.setOnClickListener(new OnClickListener() { 

     @Override 
     public void onClick(View v) { 

      Uri uri = Uri.parse(path); 

      Intent intent = new Intent(context, MuPDFActivity.class); 

      intent.setAction(Intent.ACTION_VIEW); 

      intent.setData(uri); 

      startActivity(intent); 


     } 
    }); 

    onPdf.setOnClickListener(new OnClickListener() { 

     @Override 
     public void onClick(View v) { 

      Uri uri = Uri.parse(netPath); 


      Intent intent = new Intent(context, MuPDFActivity.class); 

      intent.setAction(Intent.ACTION_VIEW); 

      intent.setData(uri); 

      startActivity(intent); 

     } 
    }); 

MuPDFActivity Modified - a cambiare tutti i file sono il metodo openBuffer aperto

private MuPDFCore openBuffer(byte buffer[]) { 
    System.out.println("Trying to open byte buffer"); 
    try { 
     String magic = ""; 
     core = new MuPDFCore(this, buffer, magic); 
     // New file: drop the old outline data 
     OutlineActivityData.set(null); 
    } catch (Exception e) { 
     System.out.println(e); 
     return null; 
    } 
    return core; 
}

Answer 1

posso scaricare PDF f ile e convertire in byte e aprire in MuPDF Core.

file Download

byte buffer[] = null; 
    HttpURLConnection urlConnection = null; 
    try { 

     urlConnection = (HttpURLConnection) urls[0].openConnection(); 
     urlConnection.setReadTimeout(TIMEOUT_READ); 
     InputStream inputStream = urlConnection.getInputStream(); 

     int len = inputStream.available(); 
     buffer = new byte[len]; 

     // inputStream.read(buffer, 0, len); 

     while ((len = inputStream.read(buffer)) != -1) { 
      byteBuffer.write(buffer, 0, len); 
     } 
     Log.e("Length", "" + byteBuffer.size()); 
     inputStream.close(); 
     // and then we can return your byte array. 

    } catch (Exception e) { 
     e.printStackTrace(); 

     });

RelativeLayout mupdfWrapper; 
MuPDFCore core; 
public byte[] buffer; 
mupdfWrapper = (RelativeLayout) viewRoot 
       .findViewById(R.id.mupdf_wrapper); 
     // Intent intent =new Intent(getActivity(),MuPDFActivity.class); 
     // startActivity(intent); 

     core = new MuPDFCore(getActivity(), buffer, ""); 
     MuPDFReaderView mDocView = new MuPDFReaderView(getActivity()); 
     mDocView.setAdapter(new MuPDFPageAdapter(getActivity(), core)); 
     mupdfWrapper.addView(mDocView, new LayoutParams(
       LayoutParams.MATCH_PARENT, LayoutParams.WRAP_CONTENT));
