First of all you have to sort usb device issue since your computer is not able to install the drivers for the usb you connected I can see this in your image.
Follow these steps :

<ol>
<li>Completely Shutdown your computer and remove the power cable. (Also remove the battery if you own a laptop). Leave it unplugged for about 5-10 minutes and then re-plug the power cord (and the battery). Turn On your computer and check if your USB devices are working.</li>
<li>If you own a laptop:

<ul>
<li>Turn off your laptop.</li>
<li>Unplug the AC power adapter and the battery.</li>
<li>Leave your computer without power for about 15 minutes.</li>
<li>Reinsert the battery</li>
<li>Turn on your laptop.</li>
<li>Plug one by one all USB devices.</li>
<li>Check if the USB not recognized problem is solved and the USB devices are working.</li>
<li>Plug the AC power adapter.

<ol start="3">
<li>Change the USB cable that connects your computer with the USB device.</li>
</ol></li>
</ul></li>
</ol>

Hope this will sort Your issue with USB as this works for me..

Next 

<ol>
<li>Go to this <a href="http://developer.samsung.com/technical-doc/view.do?v=T000000117" rel="nofollow">Samsung Usb Drivers</a>
Download and Install Usb Drivers ..
Now connect your device with your computer /Laptop via usb cable..
Wait for drivers to install completely..
Now</li>
<li>On android device: go to Settings > Developer Options and enable it
Then enable "USB Debugging"</li>
<li>Start Android Studio Click on Debug Button check if your device name is there in connected device
If the device name is their in connected device name,then you can go with debugging.

Go to settings > additional settings > developer options > Install via usb.

I have developed an Android application using Android Studio. It is working smoothly on Simulator. But after testing on a real device by exporting the apk file it throws an exception. 

So I want to solve that problem by testing in a real device, but I'm not able to do it.

There is an error like this in the image:

<a href="https://i.stack.imgur.com/a3QR8.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/a3QR8.png" alt="enter image description here"></a>

How do I test it on my real device?

I have an android Phone Samsung Galaxy j3 (model no: sm-j320f).

我已经使用Android Studio开发了一个Android应用程序。它在模拟器上工作得很顺利。但在真实设备上通过导出apk文件进行测试后，它抛出了一个异常。所以我想通过在真实的设备上测试来解决这个问题，但我无法做到。在图像中有一个类似如下的错误：​​如何在我的真实设备上测试它？我有一部安卓手机三星Galaxy j3 (型号: sm-j320f)。
