How to open local PDF file in WebView in Android?

Question

I want to open local (SD card) PDF file in a WebView.

I already tried this:

webview = (WebView) findViewById(R.id.webview);
webview.getSettings().set         


        

Answer 1

From android OS 5.0(lollipop) on-wards you can use PdfRenderer instead of webview/library. You can use this class to show pdf's within the app.

If you want to support OS lower than that you can use a library/other approach mentioned in other answer as there is no native support.

Read more about it from the docs, you can also refer this example

Answer 2

you can use the SkewPdfView library for loading pdf from remote or local urls.

First of all, Add following in your root build.gradle:

allprojects {
repositories {
    ...
    maven { url 'https://jitpack.io' }
}

}

and add the SkewPdfView Library as:

dependencies {
    implementation 'com.github.naya-aastra:SkewPdfView:1.1'
}

Now Include SkewPdfView in your layout:

<com.nayaastra.skewpdfview.SkewPdfView
    android:id="@+id/skewPdfView"
    android:layout_width="match_parent"
    android:layout_height="match_parent"/>

Save all the local files in assets folder and then use SkewPdfView as follows. Load a PDF file programmatically as:

SkewPdfView skewPdfView;
skewPdfView = findViewById(R.id.skewPdfView);
String pdfLink = "LINK TO ASSET FILE";
skewPdfView.loadPdf(pdfLink);

As @Sameer replied in your comment above, the only solution to view PDF in webview is through Google Docs' online viewer which will render and send back a readable version to your app.

• Open a pdf file inside a webview.

Answer 4

After going through several posts I came across this simple answer on Quora which pretty much do the work. Following are steps:-

Add this dependency in your gradle file:

compile 'com.github.barteksc:android-pdf-viewer:2.0.3'

activity_main.xml

 <com.github.barteksc.pdfviewer.PDFView
    android:id="@+id/pdfView"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
     />

MainActivity.java

package pdfviewer.pdfviewer;

import android.app.Activity;
import android.os.Bundle;
import android.util.Log;
import com.github.barteksc.pdfviewer.PDFView;
import com.github.barteksc.pdfviewer.listener.OnLoadCompleteListener;
import com.github.barteksc.pdfviewer.listener.OnPageChangeListener;
import com.github.barteksc.pdfviewer.scroll.DefaultScrollHandle;
import com.shockwave.pdfium.PdfDocument;

import java.util.List;

public class MainActivity extends Activity implements OnPageChangeListener,OnLoadCompleteListener{
    private static final String TAG = MainActivity.class.getSimpleName();
    public static final String SAMPLE_FILE = "sample_pdf.pdf";
    PDFView pdfView;
    Integer pageNumber = 0;
    String pdfFileName;

    @Override    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);


        pdfView= (PDFView)findViewById(R.id.pdfView);
        displayFromAsset(SAMPLE_FILE);
    }

    private void displayFromAsset(String assetFileName) {
        pdfFileName = assetFileName;

        pdfView.fromAsset(SAMPLE_FILE)
                .defaultPage(pageNumber)
                .enableSwipe(true)

                .swipeHorizontal(false)
                .onPageChange(this)
                .enableAnnotationRendering(true)
                .onLoad(this)
                .scrollHandle(new DefaultScrollHandle(this))
                .load();
    }


    @Override    public void onPageChanged(int page, int pageCount) {
        pageNumber = page;
        setTitle(String.format("%s %s / %s", pdfFileName, page + 1, pageCount));
    }


    @Override    public void loadComplete(int nbPages) {
        PdfDocument.Meta meta = pdfView.getDocumentMeta();
        printBookmarksTree(pdfView.getTableOfContents(), "-");

    }

    public void printBookmarksTree(List<PdfDocument.Bookmark> tree, String sep) {
        for (PdfDocument.Bookmark b : tree) {

            Log.e(TAG, String.format("%s %s, p %d", sep, b.getTitle(), b.getPageIdx()));

            if (b.hasChildren()) {
                printBookmarksTree(b.getChildren(), sep + "-");
            }
        }
    }

}

You have to make sure that your asset folder contains sample_pdf.pdf (Library also support opening pdf from Uri and SDCard)

Happy coding :)

Answer 5

WebView can not open a .pdf file. The most popular solution (google docs' url + your url in WebView) just shows you converted by google docs pictures. However there is still no simple way to open .pdf from url.

Answer 6

You cannot. Using an Intent, you can open the PDF in an external viewer application like Acrobat Reader:

try
{
 Intent intentUrl = new Intent(Intent.ACTION_VIEW);
 intentUrl.setDataAndType(uri, "application/pdf");
 intentUrl.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
 mActivity.startActivity(intentUrl);
}
catch (ActivityNotFoundException e)
{
 Toast.makeText(mActivity, "No PDF Viewer Installed", Toast.LENGTH_LONG).show();
}
