# SdkDiagnostics

Container for SDK diagnostics observers.

Use this class to register callbacks for internal SDK diagnostic events and pass them to `SentianceOptions.Builder.diagnostics(...)` during SDK initialization.

## SdkDiagnostics API

### `getGooglePlayServicesObserver`

> ```java
> @Nullable GooglePlayServicesObserver getGooglePlayServicesObserver()
> ```
>
> Returns the [observer](/important-topics/sdk/api-reference/android/sdkdiagnostics/googleplayservicesobserver.md) for Google Play Services related diagnostic events.\
> Returns `null` if no Google Play Services observer is configured.

### `getServiceLifecycleObserver`

> ```java
> @Nullable ServiceLifecycleObserver getServiceLifecycleObserver()
> ```
>
> Returns the [observer](/important-topics/sdk/api-reference/android/sdkdiagnostics/servicelifecycleobserver.md) for SDK service lifecycle diagnostic events.\
> Returns `null` if no service lifecycle observer is configured.

## SdkDiagnostics.Builder API

Builder class for `SdkDiagnostics`.

### `Builder`

> ```java
> Builder()
> ```
>
> Creates a builder used to configure diagnostics observers.

### `googlePlayServicesObserver`

> ```java
> Builder googlePlayServicesObserver(GooglePlayServicesObserver observer)
> ```
>
> Registers an [observer](/important-topics/sdk/api-reference/android/sdkdiagnostics/googleplayservicesobserver.md) for Google Play Services related diagnostic events.\
> Returns the same builder instance for chaining.

### `serviceLifecycleObserver`

> ```java
> Builder serviceLifecycleObserver(ServiceLifecycleObserver observer)
> ```
>
> Registers an [observer](/important-topics/sdk/api-reference/android/sdkdiagnostics/servicelifecycleobserver.md) for SDK service lifecycle diagnostic events.\
> Returns the same builder instance for chaining.

### `build`

> ```java
> SdkDiagnostics build()
> ```
>
> Builds and returns a `SdkDiagnostics` instance containing the configured observers.

## Example

```java
SdkDiagnostics diagnostics =
        new SdkDiagnostics.Builder()
                .googlePlayServicesObserver(myGooglePlayServicesObserver)
                .serviceLifecycleObserver(myServiceLifecycleObserver)
                .build();

SentianceOptions options =
        new SentianceOptions.Builder(context)
                .diagnostics(diagnostics)
                .build();
```
