I have an error initializing ADB : Android debud bridge not found message on my mac . What should i do?

I am trying to connect my android phone to my android studio via my macbook but the android studio keeps displaying the “Error initializing ADB: Android Debug Bridge not found” message.
Please let me know on what i should do .
thanks
First go to File>Invalidate Caches and Restart.
After restart, in the terminal write the command adb devices. If you get the error, as you mentioned then that means you don't have adb installed. But as far as I have used Android Studio, you don't get this error in Linux and Mac.
Also if you are trying to connect to your physical phone, then you need to enable Developer Options, and then check enable USB Debugging.

Android studio app run error for virtual device

When I develop an app, I use a virtual machine but when I run the app it gives an error message that says
Instant Run requires 'Tools |Android| Enable ADB integration' to be enabled.
What should I do?
You can do it according to the picture,and choose the Enable ADB Integration.

Debugging not working in Android Studio

I am unable to debug my app in Android Studio. It always keep showing this message
Warning: debug info can be unavailable. Please close other application using ADB: Monitor, DDMS, Eclipse
Restart ADB integration and try again
Waiting for process: com.#######
I can't debug by any method neither run time nor launching app in debug mode.
Did you turn it on the Android side? The option is hidden behind a backdoor now.
Then Windows need driver, Linux does not need driver, same might be but I don't know goes to Mac OS X. Windows driver for Nexuses are already included.
This method that I'm writing it works for windows :
1-You need to get your device's drivers using the manufacturer's website. (ADB Drivers).This is a must for debugging and it seems that it is where your problem is lying beneath. If you use a simulator like Genymotion, skip this step.
2-Enable USB debugging from developer options.
3-Connect your device.
As the error message is displaying
Warning: debug info can be unavailable. Please close other application using ADB: Monitor, DDMS, Eclipse
You have Eclipse program running which is using the ADB Connection. So first close the Eclipse Program and Try Debugging in Android Studio, if problem persist then restart Android Studio or restart machine

Visual Studio & Xamarin: deploy to Hyper-V emulator failed

When I'm trying to run my project Xamarin.Android in Hyper-V with Visual Studio 2015 RC (generally speaking, this error/bug or whatever may occur in different VS versions), I'm getting no deploy process to the emulator. However, the emulator has starting successfully, but nothing deployed into it. After closing the emulator, I'm getting this message:
Build Failed: MonoDroid does not support running the previous
version. Please ensure your solution builds before running or
debugging it.
My solution is:
Connect to android device in Hyper-V
Run in terminal "su root"
Run "netcfg" to obtain device ip addrress
Then in ADB command prompt type "adb connect 192.168.1.63"
After this VS/Xamarin begins the deploying process and all working fine.
End :)
Is this a bug OR can Xamarin/Visual Studio deploy applications (for example, android) to the device emulator automatically?
