android-sdk - unable to run the SDK manager

  • 772

I'm trying to run the Android SDK manager tool using the following command inside the folder where android-sdk-tools are located.

./sdkmanager

It gives me the following error.

Error: Could not find or load main class com.android.sdklib.tool.SdkManagerCli

Can someone please help with this?

android android-sdk

  1. I got this, so I went looking on a system where it worked. The command lives here:

    unzip -t Android/Sdk/tools/lib/sdklib-26.0.0-dev.jar | grep sdkman
testing: com/android/sdklib/tool/sdkmanager/   OK
testing: com/android/sdklib/tool/sdkmanager/ListAction.class   OK
...etc

    This zip doesn't exist on my bad machine. I have no idea why, and some of the .jar files in there complain about 

    bad extra-field entry:
  EF block length (0 bytes) invalid (< 4)

    but I just copied what I needed from a working machine.

    Another cleaner way to go about this is to follow the following steps:

    • Go to /path-to-android-sdk/
    • Delete the Tools directory
    • Open Android Studio
    • Open tools -> Sdk Manager
    • Click on the Sdk Tools Tab
    • Uncheck Hide Obsolete Packages
    • Go into the Modal and check Android Sdk Tools (Obsolete)
    • Click Apply
    • Wait While it Downloads....
    • When download is done,go back to /path-to-android-sdk/
    • You should find your tools directory again
    • Everything should work fine now.

    Note: What we simply did was delete and replace the old Tools which was corrupted or incompatible
