### 1. 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();
    }
```

### 2. 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");
```

### 3. 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'
   }
   ```

### 4. 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:‘
   //    … 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.

### 5. I received a policy violation notice from Google Play Store when trying to publish my Razorpay-integrated app. How do I proceed?

This error appeared due to an intent redirection issue that was present in the older versions of the Razorpay Android Custom SDK. To resolve this, please [upgrade](/payments/payment-gateway/android-integration/custom#step-1-install-razorpay-android-custom-sdk) to the latest SDK version.

    options.put("subscription_id", subscription_id);
    razorpay.getPaymentMethods(options, new PaymentMethodsCallback() {
   	 @Override
   	 public void onPaymentMethodsReceived(String result) {
   	 	JSONObject paymentMethods = new JSONObject(result);
   	 }

   	 @Override
   	 public void onError(String error){

   	 }
   	 });
    });
```

### 7. How to fetch Subscription amount?

If you are using [Subscriptions](/payments/subscriptions), you can fetch the subscription amount by calling the `getSubscriptionAmount` method.

```java: Fetch Subscription Amount theme={null}
