I need to install some packages in Android SDK Manager, but in my SDK folder there isn't the .exe file (There is only the AVD Manager and the folders).
How can I find it? My SDK works normally with Android Studio, without problems, it's strange that SDK Manager.exe isn't there.
I had to install an older version https://dl.google.com/android/installer_r24.4.1-windows.exe and update it. Going from there worked
To open the SDK Manager from Android Studio, click Tools > Android > SDK Manager or click SDK Manager in the toolbar. If you're not using Android Studio, you can download tools using the sdkmanager command-line tool.
Check this link: https://developer.android.com/studio/intro/update.html#sdk-manager
Go to android_sdk/tools/bin/ open cmd and type sdkmanager and hit enter you can use command prompt for it
I found C:\NVPACK\android-sdk-windows\tools\android.bat
When I ran it, it brought up SDK Manager.
Which was nice, because I couldn't find SDK Manager in the C:\NVPACK\android-sdk-windows\lib folder like I was told it would be there.
You can find Android SDK Manager.exe file in the following folder:
C:\Users[account]\AppData\Local\Android\sdk (sdk1 in my case)
You can tap on that and you will get the Android SDK Manager screen.
