Read an online PDF using MuPDF

Question

I have two questions 1) Annotations do not work 2) I want to read an online PDF document

I am creating MuPDF using this link http://mupdf.com/doc/how-to-build-mupdf-for-android

1) I get the mupdf / platform / android project I run this default application annotation, it works fine, but I create this project in the library file that they want to save, but the annotations are not saved.

2) It will read the local file, but I also want to read the online file. my android code

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); } }); 

Modified MuPDFActivity - I change the whole file to the openBuffer open method

 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; } 

My main resident

 <application android:allowBackup="true" android:icon="@drawable/ic_launcher" android:label="@string/app_name" android:theme="@style/AppTheme" > <activity android:name=".PdfTestActivity" android:label="@string/app_name" > <intent-filter> <action android:name="android.intent.action.MAIN" /> <category android:name="android.intent.category.LAUNCHER" /> </intent-filter> </activity> <activity android:name="com.artifex.mupdfdemo.MuPDFActivity" android:label="@string/app_name" android:theme="@style/AppBaseTheme" > </activity> <activity android:name="com.artifex.mupdfdemo.OutlineActivity" android:label="@string/outline_title" android:theme="@android:style/Theme.Light.NoTitleBar.Fullscreen" > </activity> <activity android:name="com.artifex.mupdfdemo.PrintDialogActivity" android:label="@string/print" android:theme="@android:style/Theme.Light.NoTitleBar.Fullscreen" > </activity> </application>

Answer 1

I download a PDF file and convert to Bytes and open MuPDF in the kernel.

Upload file

 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(); }); 

Open core

 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));
