# Does my app need cleartext network traffic support?

World's #1 PDF SDK Library for Web, Mobile, Server, Desktop

In order to view remote documents from an HTTP URL, cleartext network traffic support is required. On Android 9.0 (API level 28) or higher, cleartext support is disabled by default and apps targeting Android 9.0 or higher will need to add the `android:usesCleartextTraffic="true"` flag in the `AndroidManifest.xml` file. If you are only working with HTTPS files, this flag is not required.

**Example:**

{% tabs %}
{% tab title="XML" %}
{% code lineNumbers="true" %}

```xml
<?xml version="1.0" encoding="utf-8"?>
<manifest ...>

    <!-- Required permissions are added here -->
    <uses-permission android:name="android.permission.INTERNET"/>
    <uses-permission android:name="android.permission.RECORD_AUDIO" />

    <!-- Add multidex support and enable largeHeap. Also enable usesCleartextTraffic in application attributes if you are working with HTTP files. If you are only working with HTTPS files, this is not required.-->
    <application android:name="androidx.multidex.MultiDexApplication" android:largeHeap="true" + android:usesCleartextTraffic="true" ...>    
        ...
    </application>
</manifest>
```

{% endcode %}
{% endtab %}
{% endtabs %}

## 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.apryse.com/android/get-started/faq/uses-clear-text-traffic.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.
