# Android SDK: Prefill the widget form

> Prefill feedback form fields with known values with the Gleap Android SDK. Follow the integration code examples.

In some situations you might want to prefill some fields for the user. This can be achieved by the following method.

```java theme={null}
JSONObject prefill = new JSONObject();
try{
    prefill.put("description", "Prefill the description with this.");
}catch (Exception ex){
    ex.getStackTrace();
}

PrefillHelper.getInstance().setPrefillData(prefill);
```

You need to pass a key value pair to the `setPrefillData`. The key is the form identifier, which can be found under the 'Advanced' section of a question. (see screenshot for an example)
