send file arduino to android

hi
Can I transfer a file (jpg or...) from arduino to android via Bluetooth???

Withot using the terminal app on android.

Probably. All you need do is make Arduino look like a PC and use any Android file transfer app that isn't actually a terminal app. I won't ask why you don't want to use a terminal app, perhaps you can write your own Android app, and call it "not a terminal"

Because I want to send a file to people I don't know bay Bluetooth.

I don't know how make arduino looks like a PC. Do you have any information about that?

Set the arduino up as a web server and let the people download the file with their browsers.

Perhaps you should get to know them. They might tell you that using a terminal app to receive a file by Bluetooth is a really good idea.

this is the option that people will find most familiar and in the end will be easier than writing apps for each of the different phones
but the Arduino will not hold much information. data files and text files, maybe one small picture.
if you want to transfer larger files or multiple files, then there are better platforms.

First of all I want to know is there anyway to send a .jpg file from SD card to Android without any 3rd party or terminal app or not(and why not?)?

I've used an arduino with an ethernet shield that had an SD card serve .jpg pictures to requesting client browsers. Pictures can be served from ESP8266 based boards as the ESP8266 has maybe 4MB of on board memory for such things. "(and why not?)?" is your homework assignment for your project.
