Hi Masud How are you? Unfortunately I couldn't find any solution for searching through PDF android app. I used a PDF viewer but it doesn't have search function. I couldn't understand! Sorry! did you mean you could find a way to search through PDF?

Yes! What i meant to say that i’ll work to solve this issue and add the search feature into the application! But I guess you guys should approve first before i start the implementation of it :)?

I don't think you need any approval to fork the code or implement your solution. You check check it out and make changes.

look here and here

implementation 'com.google.android.gms:play-services-vision:20.1.3' // search from pdf

 ParcelFileDescriptor fileDescriptor2 = getContentResolver().openFileDescriptor(Uri.parse(getSource), "r");
 PdfRenderer pdfRenderer = new PdfRenderer(fileDescriptor2);

 for (int i=0; i<pdfRenderer.getPageCount(); i++) {
      PdfRenderer.Page page = pdfRenderer.openPage(i);
      Bitmap bmp = Bitmap.createBitmap(page.getWidth(), page.getHeight(), Bitmap.Config.ARGB_8888);
      page.render(bmp, null, null, PdfRenderer.Page.RENDER_MODE_FOR_DISPLAY);

      TextRecognizer textRecognizer = new TextRecognizer.Builder(getApplicationContext()).build();
      Frame imageFrame = new Frame.Builder().setBitmap(bmp).build();
      String imageText = "";
      SparseArray<TextBlock> textBlocks = textRecognizer.detect(imageFrame);

      for (int j = 0; j < textBlocks.size(); j++) {
            TextBlock textBlock = textBlocks.get(textBlocks.keyAt(j));
            imageText = textBlock.getValue();                   // return string
            //Log.i("here", imageText);
       }
       page.close();
 }
 pdfRenderer.close();

This app is all ready done anyone can use reverse engineering.

pdfium should have this function, the problem is to implement it for android. I remember the old app "google pdf viewer" which however was based on pdfium and had this function

I did some research and found some libraries that have implemented the search, but I don't know if they work, they should be tested. It would take someone to test them and maybe fork and keep an updated fork.

Test them and let me know if they work in any way
