[android] How to test android apps in a real device with Android Studio?

I started to develop in android with Android Studio IDE, I tested my apps on the emulator and works fine, but when I tried to test the apps directly in my device doesn't recognize it and the console shows next message:

Waiting for device. USB device not found

• I configured "USB Device" in Run>Edit Configurations...> in tab "General", menu "Target Device"
• I enabled the "Debug option" in my device
• Plug/Unplug USB

I have a Nexus 4 and own a Thinkpad L430 Windows 8.1

My errors: "Waiting for device. USB device not found"

I went to: Device Manager > View > Drop to "Acer Device" > Right click on Acer Composite ADB Interface > Update it

Afterward, Reboot/Restart your computer. Once it turned on Plug Your USB Device onto the computer.

Go to: Setting > Enable "Developer options" > Check the "USB debugging" option > Check "Allow mock locations" > Check "Verify apps over USB".

Swipe down from the drop down menu of your phone where it Shows the USB Connection Icon. Tap on USB Computer Connection > Select the Check box "Camera (PTP)"

Run your Android Studio App and it should work

I tried @Mr. Stark answer. It didn't work. It failed to install the drive. I have Samsung S8 plus. I enabled the debugging mode on device then installed Android USB Driver for Windows from Samsung site, it works.

You have to Download the driver for your Device just go to device manager-->> your device-->update driver-->choose the usb driver path from sdk extras folder and click next. You can get the correct driver and you can run on real device

• First we have to enable the USB debugging mode. for that go to Settings -> Developer Options ->USB debugging in your phone checked it and allow it.
• After it open android studio, click on SDK manager , check mark the Google USB Driver and hit install package.
• After Installing Google USB Driver, close SDK Manager window, Connect your phone or tablet through USB cable to your laptop or PC.
• Now click on My Computer (Windows 7) (or) This PC(Windows 8.1).Select Manage.
• Select Device Manager –> Portable Devices –> Your Device Name
• Right Click on Your Device Name and Select Browse My Computer For Driver Software.
• Point it to C:\Users\YourUserName\AppData\Local\Android\sdk\extras\google\usb_driver. Hit Next and Finish.
• Now Hit Run Button after selecting Your Project in Project Explorer in Android studio. Choose your device and press OK.

For Android 7, Galaxy S6 Edge:

1. Settings > Developer Options > Turn the switch ON > Debugging Mode (Turn On)

If Developer Options is not available then

2. Settings > About Device > Software Info > Build number (Tap It 7 time)

Now perform step 1. Now it should work, if its still not working then perform these steps. It worked for me.

if you are using IOS react native platform and want to debugging real android device you can use following code:

adb reverse tcp:8081 tcp:8081
npm start -- --reset-cache
react-native run-android

If USB Debugging Mode is enabled and does not work, you should install your device driver.

For Nexus Devices;

• Install Google USB Drivers on SDK Tools.
• Go to Control Panel > Device Manager and check drivers status. (Probably you can see warning icon on ADB Interface Driver.) Select ADB Interface driver and click update. Choose "Browse my computer for driver software" and set folder path like "D:\Users\userName\AppData\Local\Android\sdk".

For Another Devices;

• If you install the model's driver, it may work. For ex: Samsung Kies, LG PC Suite.

Hope it helps!

Step 1: Firstly, Go to the Settings in your real device whose device are used to run android app.

Step 2: After that go to the “About phone” if Developer Options is not shown in your device

Step 3: Then Tap 7 times on Build number to create Developer Options.

Step 4: After that go back and Developer options will be created in your device.
