Sometimes you might encounter an issue with the Android Development Tools bundle where the Android SDK manager fails to open or closes immediately after showing a command prompt like a window. Fortunately, it is really easy to solve.
Step 1 : Go to [sdk-folder]/tools folder (For me it was C:\adt-bundle-windows-x86_64-20130522\sdk\tools).
Step 2 : Open the file android.bat in notepad by right clicking on it and selecting Edit from the context menu.
Step 3 : Find the line in the file that says java_exe.
Step 4: Now edit the “set java_exe=” line to
set java_exe="C:\Program Files\Java\jre7\bin\java.exe"
Here “C:\Program Files\Java\jre7\bin\java.exe” is the path where the java.exe file for the JRE is installed. You should check your Java executable location and change the line accordingly.
Now save the file and close it. To test it out, in Eclipse go to Window > Android SDK Manager.
Ta daa ..!
