Read a file as binary data in JavaScript on the client side -

-

as question states, i'd way read files on client side using javascript (is there other possible alternative?).

these files(images mostly) part of webpage, , not need access filesystem.

so question should reduce to, possible open file in binary mode in javascript , read byte byte?

there seems confusion i'm trying achieve. question how load binary image data using javascript , xmlhttprequest? deals case when user able make own requests server , set own mime-types etc.

i wish create js function/script reads loaded files on web-page binary, purposes of meta-data extraction.

android - getbluetoothservice() called with no bluetoothmanagercallback -

i getting getbluetoothservice() called no bluetoothmanagercallback error in android application. i have no idea causing or bluetooth manager callbacks. can give me idea of causing problem or start looking. by reading android source code, seems warning cannot about. source code shows if call bluetoothsocket#connect(); then call bluetoothadapter.getdefaultadapter().getbluetoothservice(null); the key here, null parameter passes in above line. due this, there no callback, , bluetoothsocket class throw out warning. since warning, not think need it. https://android.googlesource.com/platform/frameworks/base/+/master/core/java/android/bluetooth/bluetoothsocket.java line 306 https://android.googlesource.com/platform/frameworks/base/+/master/core/java/android/bluetooth/bluetoothadapter.java line 1610
