Eclipse Error "Adb Server Didn't Ack, Failed to Start Daemon"

Eclipse error ADB server didn't ACK, failed to start daemon

I have solved my first question: Open Eclipse, open the SDK Manager, and choose the device to open.

Or you can open the SDK directory. Open the SDK Manager, and then choose the device to open

2: Close Eclipse, and then open it.

How to resolve the ADB server didn't ACK error?

Try the following:

1. Close Eclipse.
2. Restart your phone.
3. End adb.exe process in Task Manager (Windows). In Mac, force close in Activity Monitor.
4. Issue kill and start command in <sdk_folder>\platform-tools\
   
   • C:\sdk\platform-tools>adb kill-server
   • C:\sdk\platform-tools>adb start-server
5. If it says something like 'started successfully', you are good.

Error initializing ADB: Unable to create Debug Bridge: Unable to start ADB server

There are a couple of solutions depending on what exactly is causing the problem.

So, just follow the following steps.

Step 1:- Close Android-Studio.

Step 2:- Open Command prompt or win + r, type cmd and press Enter.

Step 3:- Navigate to your platform-tools, in most of the cases the location is:

C:\Users\[user]\AppData\Local\Android\android-sdk\platform-tools

but in your case, the location is:

C:\Android\Sdk\

For Mac users the path is

/Users/[user]/Library/Android/sdk/platform-tools

Step 4:- Type adb.exe start-server, Press Enter

Step 5:- Open Android Studio again.

For Mac the command is just adb start-server

The problem should be solved!

If the problem persists, then follow these steps-

Step 1:- Close Android Studio.

Step 2:- Press Alt + Ctrl + Del, then choose Start Task Manager.

Windows Task Manager opens.

Step 3:- Go to the processes tab.

Step 4:- Look for adb.exe and select that.

Step 5:- Press End Process.

Step 6:- Open Android Studio again.

That's it. Now your problem must be solved!

But if the problem is still there (which I don't think will happen), then there is something wrong (or might be missing) in your platform-tools.

To fix that, delete platform-tools from your computer, then download them again from Official Android Developer website.

Extract the downloaded file.

Now place the extracted file, where platform-tools were located before deleting.

Default Location of platform-tools is

C:\Users\[user]\AppData\Local\Android\android-sdk\

But in your case, the location is

C:\Android\Sdk\
