# Deliverables

NFC Wallet SDK for Android includes libraries to integrate into your **digital wallet application**.

The delivery package also includes API documentation to support your integration.

### Library naming

Library files follow this naming convention:

`TSHPaySDK-<build type>-<version number>.<version qualifier>.aar`

`<version qualifier>` is optional and depends on the delivery (for example, `rc1`).

### Build types

`<build type>` is one of:

* `release`: Use for `Production` and certification builds.
* `dev`: Use for development and testing only. It is functionally equivalent to `release`, except it enables SDK logging, HTTP inspection, and debugging. Do not release a **digital wallet application** that includes the `dev` build.

{% hint style="warning" %}
Do not use the `dev` SDK build in `Production`.

* For `Production`, set your **digital wallet application** to non-debuggable:
  * Set `debuggable false` in `build.gradle`.
  * Set `android:debuggable="false"` in `AndroidManifest.xml`.
* If a `Production` build initializes with the `dev` library, initialization fails with `DEBUG_SDK_USED`.
  {% endhint %}

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.payments.thalescloud.io/nfc-wallet-sdk-android/general/deliverables.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
