Display PDF file inside my android application

Question

I cannot figure out how to show a PDF file inside an Android application. So far I've found out that it is possible to launch an Intent and open the PDF using the Android default app. But I want to view PDF file directly inside my application without exiting. I have an header and a footer in my layout - I'd like to open the PDF in between. I have also found a PdfReader.jar file from github.com, but it opens the PDF in a new activity.

You can download the source from here(Display PDF file inside my android application)

Add this dependency in your gradle file:

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

activity_main.xml

<RelativeLayout android:layout_width="match_parent"     android:layout_height="match_parent"     android:background="#ffffff"     xmlns:android="http://schemas.android.com/apk/res/android" >      <TextView         android:layout_width="match_parent"         android:layout_height="40dp"         android:background="@color/colorPrimaryDark"         android:text="View PDF"         android:textColor="#ffffff"         android:id="@+id/tv_header"         android:textSize="18dp"         android:gravity="center"></TextView>      <com.github.barteksc.pdfviewer.PDFView         android:id="@+id/pdfView"         android:layout_below="@+id/tv_header"         android:layout_width="match_parent"         android:layout_height="match_parent"/>       </RelativeLayout> 

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 = "android_tutorial.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 + "-");             }         }     }  }

Maybe you can integrate MuPdf in your application. Here is I've described how to do this: Integrate MuPDF Reader in an app
