# Uploading and Analyzing Media

### Server-Based Analyzes

Data to be uploaded and analyzed is stored in object sdkMediaResult, obtained after capturing and recording video. Upload it to the server and initiate required analyses via [Oz API](/oz-knowledge/guides/developer-guide/api/oz-api.md).

A simple scenario of interaction with Oz API can be implemented with the`uploadMediaAndAnalyze` method as described below.

{% tabs %}
{% tab title="Kotlin" %}

```kotlin
val statusListener = object: StatusListener<List<OzAnalysisResult>> {
            override fun onStatusChanged(status: String?) { /*your code for showing status message*/ }
            override fun onSuccess(result:List <OzAnalysisResult>) { /*your code to handle analysis result*/ }
            override fun onError(error: OzException) { /*your code to handle analysis error*/ }
        }
        val analysisCancelable = OzLivenessSDK.uploadMediaAndAnalyze(
            mediaList,
            listOf(OzAnalysis.QUALITY, OzAnalysis.BIOMETRY),
            statusListener
        )
```

{% endtab %}

{% tab title="Java" %}

```java
StatusListener<List<OzAnalysisResult>> statusListener = new StatusListener<List<OzAnalysisResult>>() {
            @Override public void onStatusChanged(@Nullable String s) { /*your code for showing status message*/ }
            @Override public void onSuccess(List<OzAnalysisResult> result) { /* your code to handle analysis result */ }
            @Override public void onError(@NonNull OzException e) { /* your code to handle analysis error */ }
        };
        Cancelable analysisCancelable = OzLivenessSDK.INSTANCE.uploadMediaAndAnalyze(
            mediaList,
            Arrays.asList(OzAnalysis.QUALITY, OzAnalysis.BIOMETRY),
            statusListener
        );
```

{% endtab %}
{% endtabs %}

#### On-Device Analyzes

To run the on-device analyses instead of server-based, use the following methods:

{% tabs %}
{% tab title="Kotlin" %}

```kotlin
OzLivenessSDK.runOnDeviceLivenessAnalysis(mediaList)
OzLivenessSDK.runOnDeviceBiometryAnalysis(mediaList)
```

{% endtab %}

{% tab title="Java" %}

```java
OzLivenessSDK.INSTANCE.runOnDeviceLivenessAnalysis(mediaList);
OzLivenessSDK.INSTANCE.runOnDeviceBiometryAnalysis(mediaList);
```

{% endtab %}
{% endtabs %}
