Use the lib https://github.com/barteksc/PdfiumAndroid

public Bitmap getBitmap(File file){
 int pageNum = 0;
            PdfiumCore pdfiumCore = new PdfiumCore(context);
            try {
                PdfDocument pdfDocument = pdfiumCore.newDocument(openFile(file));
                pdfiumCore.openPage(pdfDocument, pageNum);

                int width = pdfiumCore.getPageWidthPoint(pdfDocument, pageNum);
                int height = pdfiumCore.getPageHeightPoint(pdfDocument, pageNum);


                // ARGB_8888 - best quality, high memory usage, higher possibility of OutOfMemoryError
                // RGB_565 - little worse quality, twice less memory usage
                Bitmap bitmap = Bitmap.createBitmap(width , height ,
                        Bitmap.Config.RGB_565);
                pdfiumCore.renderPageBitmap(pdfDocument, bitmap, pageNum, 0, 0,
                        width, height);
                //if you need to render annotations and form fields, you can use
                //the same method above adding 'true' as last param

                pdfiumCore.closeDocument(pdfDocument); // important!
                return bitmap;
            } catch (IOException ex) {
                ex.printStackTrace();
            }
            return null;
}

 public static ParcelFileDescriptor openFile(File file) {
        ParcelFileDescriptor descriptor;
        try {
            descriptor = ParcelFileDescriptor.open(file, ParcelFileDescriptor.MODE_READ_ONLY);
        } catch (FileNotFoundException e) {
            e.printStackTrace();
            return null;
        }
        return descriptor;
    }
