I cant drag and drop items either on activity_main.xml file or content_main.xml file. From my research, I learned that I have to downgrade from android API 24 to android API 23, but when I click on API 24 image to downgrade I can't find API 23.

    You have to install other SDK. Go to SDK Manager and install lower versions of sdk, then restart. – danypata Jul 29 '16 at 13:27

Check the image and download API 23, then restart Android Studio and you will see API 23 too there.

You will see this window, then start the download:

I think you are confusing rendering API level to application API level. You see, the icon above will render according to the API level you chose. That makes seance because some APIs have different overall design.

If you want to downgrade the application API you can change in the manifest (if you are using eclipse) OR change in the gradle settings(if you are using Android Studio) like so:

In the build.gradle(Module app):

    defaultConfig {
    applicationId "com.shlomi.alarm"
    minSdkVersion 17
    targetSdkVersion 24
    versionCode 1
    versionName "1.0"
    }

Insert your API level in minSdkVersion.

Simply go to your res directory through your windows explorer there you may find folders like 1)drawable 2)drawable-v24 3)layouts and so on..... cut all the content from drawable-v24 and paste it into drawable folder. This solution worked for me. cheers.
