Once you click on the Browse… button, you will be displayed with the following dialog box where you need to select the appropriate JDK7 path.
Step 3: After this step, you will be asked to select the Android Studio components as per your requirement. Keep in mind that you need to select all the components as all of these will be helpful in the Android application development. So, you will be selecting all the components which include Android Studio, Android SDK, Android Virtual Device, and Performance (Inter chip).
Step 4: After this step Android Studio Setup, you will be asked to enter the local machine path for both the Android Studio and Android SDK. As mentioned in the below figure, ensure that the specified location must have a minimum of 500 MB of available disk space.
