I can assure the in my phone I have a pdf file named "adobe.pdf" at /storage/emulated/0/Documents/adobe.pdf
I downloaded the pdf through a URL link and the stored in Documents. Here is how I downloaded it and stored it. This is another activity within the same app.
public void DownloadBooks(String url,String title){
DownloadManager.Request request=new DownloadManager.Request(Uri.parse(url));
String tempTitle=title.trim();
request.setTitle(tempTitle);
if(Build.VERSION.SDK_INT>= Build.VERSION_CODES.HONEYCOMB){
request.allowScanningByMediaScanner();
request.setNotificationVisibility(DownloadManager.Request.VISIBILITY_VISIBLE_NOTIFY_COMPLETED);
}
request.setDestinationInExternalPublicDir(Environment.DIRECTORY_DOCUMENTS,tempTitle+".pdf");
DownloadManager downloadManager=(DownloadManager)getSystemService(Context.DOWNLOAD_SERVICE);
request.setMimeType("application/pdf");
request.allowScanningByMediaScanner();
request.setAllowedNetworkTypes(DownloadManager.Request.NETWORK_MOBILE | DownloadManager.Request.NETWORK_WIFI);
downloadManager.enqueue(request);
}
DownloadBooks("a link"," adobe");
After the download has completed the pdf adobe.pdf is stored at /storage/emulated/0/Documents/ and I want to view this downloaded PDF.
I am using the library to display the PDF but it is not visible. Here is my code
package com.shivansh.firebasedemo;
public class DownloadedPDFViewerActivity extends AppCompatActivity implements ViewPager.OnPageChangeListener, OnLoadCompleteListener {
PDFView pdfView;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_downloaded_p_d_f);
pdfView =findViewById(R.id.pdfView);
File root = Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DOCUMENTS);
File file = new File(root,"adobe.pdf");
Log.i("5656",file.toString());
pdfView.fromFile(file).
enableSwipe(true)
.defaultPage(0)
.swipeHorizontal(false)
.onLoad(this)
.load();
}
@Override
public void onPageScrolled(int position, float positionOffset, int positionOffsetPixels) {
}
@Override
public void onPageSelected(int position) {
}
@Override
public void onPageScrollStateChanged(int state) {
}
@Override
public void loadComplete(int nbPages) {
}
}
The above log statements prints
2021-05-06 03:13:31.734 9470-9470/com.shivansh.firebasedemo I/5656: /storage/emulated/0/Documents/adobe.pdf
Which suggests that I have located the correct location of the file on the device.
Now , how do I make this pdf to render in my activity ?
