  <Accordion title="How to handle situations where a customer has pressed the Back button on the browser before the payment is complete?">
    You can use the `onBackPressed` method to handle a situation where the customer has pressed the Back button before completing the payment. This marks the payment as `failed` on the Dashboard.

    ```java onBackPressed Method theme={null}
    			 /**
    			 * In your activity, you need to override onBackPressed
    			 */
    			 @Override
    			 public void onBackPressed() {
    				 if(razorpay != null){
    				 	razorpay.onBackPressed();
    				 }
    				 super.onBackPressed();
    			 }
    ```
  </Accordion>

  <Accordion title="How to change API keys?">
    You can change API keys after you have already initialized the `Razorpay` object by calling `razorpay.changeMerchantKey(merchantKey)`. This is an optional method that overrides the existing API key. The new key is used for authenticating the requests sent to Razorpay.

    ```java API Key Change theme={null}
    		 /**
    		 * change the API key
    		 */
    		 razorpay.changeMerchantKey("YOUR_KEY_ID");
    ```

  <Accordion title="How can I check the Razorpay Android Custom SDK version?">
    To check the SDK version:

    1. Open your Android project in Android Studio.
    2. Navigate to the `build.gradle` file of your app module (usually `app/build.gradle`).
    3. Locate the `dependencies` block in the file.
    4. Find the line that includes the Razorpay SDK dependency. The version number will be alongside the SDK name in the format`x.y.z`.

    ```java build.gradle theme={null}
    			 dependencies {
    			 implementation 'com.razorpay:customui:3.9.22'
    			 }
    ```
  </Accordion>

  <Accordion title="How can I update the Razorpay Android Custom SDK version?">
    To update the Custom Android SDK, follow these steps:

    1. Check the [latest SDK version](https://mvnrepository.com/artifact/com.razorpay/customui).
    2. In the app-level gradle build file, update the SDK version to the latest release.

    ```java Update SDK theme={null}
    			 dependencies {
    			 //    … other dependencies
    			 //  For Razorpay checkout SDK
    			 implementation ‘com.razorpay:customui:<latest-version-name-goes-here>‘
    			 //    … other dependencies
    			
    			 }
    ```

    3. After updating, sync gradle and check for any compile-time errors.
    4. Ensure all changes are correctly integrated and the application functions as expected.
