Open folder as android studio project

Open windows registry by pressing Window + r type regedit and enter Run the registry editor Go to HKEY_CLASSES_ROOT\Directory\shell Right click on shell create a new key and name it as you want to see the entry in context menu then right click on the created file and create a new key and name it as command in lower case Click command and on right side pane you will see a key named as default Double click the default entry and enter the path of application exe file as the value. You need enter a spacebar then %1 at the end of application path that you entered as a value of default value. It worked for me.

Just save this as a .cmd file and run. Be sure to change the path to your android studio installation path.

        @echo off

    :: change the path below to match your installed version
    SET AndroidStudioPath=C:\Program Files\Android\Android Studio\bin\studio64.exe
     
    echo Adding file entries
    @reg add "HKEY_CLASSES_ROOT\*\shell\AndroidStudio" /t REG_SZ /v "" /d "Open with AndroidStudio"   /f
    @reg add "HKEY_CLASSES_ROOT\*\shell\AndroidStudio" /t REG_EXPAND_SZ /v "Icon" /d "%AndroidStudioPath%,0" /f
    @reg add "HKEY_CLASSES_ROOT\*\shell\AndroidStudio\command" /t REG_SZ /v "" /d "%AndroidStudioPath% \"%%1\"" /f
     
    echo Adding within a folder entries
    @reg add "HKEY_CLASSES_ROOT\Directory\Background\shell\AndroidStudio" /t REG_SZ /v "" /d "Open with AndroidStudio"   /f
    @reg add "HKEY_CLASSES_ROOT\Directory\Background\shell\AndroidStudio" /t REG_EXPAND_SZ /v "Icon" /d "%AndroidStudioPath%,0" /f
    @reg add "HKEY_CLASSES_ROOT\Directory\Background\shell\AndroidStudio\command" /t REG_SZ /v "" /d "%AndroidStudioPath% \"%%V\"" /f

    echo Adding folder entries
    @reg add "HKEY_CLASSES_ROOT\Directory\shell\AndroidStudio" /t REG_SZ /v "" /d "Open with AndroidStudio"   /f
    @reg add "HKEY_CLASSES_ROOT\Directory\shell\AndroidStudio" /t REG_EXPAND_SZ /v "Icon" /d "%AndroidStudioPath%,0" /f
    @reg add "HKEY_CLASSES_ROOT\Directory\shell\AndroidStudio\command" /t REG_SZ /v "" /d "%AndroidStudioPath% \"%%1\"" /f

    pause
