byte[] bytes;
try {
File file = new File(this.getFilesDir().getAbsolutePath()+"/2010Q2_SDK_Overview.pdf");
FileInputStream is = new FileInputStream(file);

long length = file.length();
bytes = new byte[(int) length];
int offset = 0;
int numRead = 0;
while (offset < bytes.length && (numRead=is.read(bytes, offset, bytes.length-offset)) >= 0) {
offset += numRead;
}
ByteBuffer buffer = ByteBuffer.NEW(bytes);
String data = Base64.encodeToString(bytes, Base64.DEFAULT);
PDFFile pdf_file = new PDFFile(buffer);
PDFPage page = pdf_file.getPage(2);
RectF rect = new RectF(0, …Run Code Online (Sandbox Code Playgroud)
