Commented Feb 23, 2018 at 11:42 You can use a library for it too.. github.com/barteksc/AndroidPdfViewer Commented Feb 23, 2018 at 11:45 You need to integrate MuPDf in your application.

File file = new File(Environment.getExternalStorageDirectory().getAbsolutePath()+"/example.pdf"); Intent intent = new Intent(Intent.ACTION_VIEW); intent.setDataAndType(Uri.fromFile(file), "application/pdf"); intent.setFlags(Intent.FLAG_ACTIVITY_NO_HISTORY); startActivity(intent); If you dont like this method, and want to open pdf files inside your application, you can use a custom PDF Viewer.
In your gradle file compile this: 'com.github.barteksc:android-pdf-viewer:2.0.3'
After you sync your project, go to your xml file and add the PDF Viewer.
Now in your .java file you will import:
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; You will Implement two methods: OnPageChangeListener and OnLoadCompleteListener
public static final String SAMPLE_FILE = "android_tutorial.pdf"; //your file path 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; >@Override public void loadComplete(int nbPages) < PdfDocument.Meta meta = pdfView.getDocumentMeta(); printBookmarksTree(pdfView.getTableOfContents(), "-"); >public void printBookmarksTree(List tree, String sep) < for (PdfDocument.Bookmark b : tree) < if (b.hasChildren()) < printBookmarksTree(b.getChildren(), sep + "-"); >> >
P.S: First search on google, if you dont find something, write your question!
