Android SDK manager won't open

Solution 1:

Make sure your java\bin directory is in your path statement before the windows\system32 directory. The SDK Manager uses java and it was finding the one in the system32 folder.

In a CMD window, you can run 'where java'. Don't forget to restart your CMD after changing the path variable for checking.

Alright, I had the same problem, and none of these answers worked for me (I'm running Windows 8). I tried running tools/android.bat and noticed I got some errors there. I investigated further and it seems there is something wrong in the code that finds your Java path.

This is how you fix it:

1. Open up tools/android.bat in your favorite text editor

2. Search for this piece of code:

   set java_exe=
   call lib\find_java.bat
   if not defined java_exe goto :EOF
   

3. Replace it with this:

   set java_exe=D:\Program Files\Java\jdk1.7.0_07\bin\java.exe 
   

   where the path is the path to your Java exe.

4. Run android.bat

(in my case I had to specify the path to java_exe in step 3 with no quotes to make it work.)

Solution 3:

There are many reasons as to why the SDK Manager won't open. Rather than trying each one of them blindly, I recommend running the android.bat in a command window so you can read the error message and apply the correct fix.

Solution 4:

In the latest version of the Android SDK, running "SDK Manager.exe" and/or "AVD Manager.exe" will not open anymore. Even the "Launch Standalone SDK Manager" link in Android Studio, which can be previously found in Android SDK Settings, is now gone.

It is now recommended to perform manual SDK and AVD management inside Android Studio. But for those who do not have an Android Studio or for those who do not like to open Android Studio just to perform SDK management, you can still manage the SDK using the command line tools, "tools/bin/sdkmanager.bat" and "tools/bin/avdmanager.bat".

This information is available when running "tools/android.bat". I think this is true for those who currently have Android SDK tooks v25.3.1 and above.
