Added in [API level 36](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)

```
public Builder ()
```

<br />

<br />

### Builder

Added in [API level 36](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)

```
public Builder (GpuHeadroomParams params)
```

Returns a new builder with the same values as this object.

<br />

| Parameters ||
|---|---|
| `params` | `GpuHeadroomParams`: This value cannot be `null`. <br /> |

## Public methods

### build

Added in [API level 36](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)

```
public GpuHeadroomParams build ()
```

Builds the `https://developer.android.com/reference/android/os/GpuHeadroomParams` object.

<br />

| Returns ||
|---|---|
| `https://developer.android.com/reference/android/os/GpuHeadroomParams` | This value cannot be `null`. <br /> |

### setCalculationType

Added in [API level 36](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)

```
public GpuHeadroomParams.Builder setCalculationType (int calculationType)
```

Sets the headroom calculation type.

<br />

<br />

| Parameters ||
|---|---|
| `calculationType` | `int`: Value is one of the following: - `https://developer.android.com/reference/android/os/GpuHeadroomParams#GPU_HEADROOM_CALCULATION_TYPE_MIN` - `https://developer.android.com/reference/android/os/GpuHeadroomParams#GPU_HEADROOM_CALCULATION_TYPE_AVERAGE` |

| Returns ||
|---|---|
| `https://developer.android.com/reference/android/os/GpuHeadroomParams.Builder` | This value cannot be `null`. <br /> |

| Throws ||
|---|---|
| `https://developer.android.com/reference/java/lang/IllegalArgumentException` | if the type is invalid. |

### setCalculationWindowMillis

Added in [API level 36](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)

```
public GpuHeadroomParams.Builder setCalculationWindowMillis (int windowMillis)
```

Sets the headroom calculation window size in milliseconds.

<br />

<br />

| Parameters ||
|---|---|
| `windowMillis` | `int`: the window size in milliseconds ranges from `https://developer.android.com/reference/android/os/health/SystemHealthManager#getGpuHeadroomCalculationWindowRange()`. The smaller the window size, the larger fluctuation in the headroom value should be expected. The default value can be retrieved from the `https://developer.android.com/reference/android/os/GpuHeadroomParams#getCalculationWindowMillis()`. The device will try to use the closest feasible window size to this param. Value is 1 or greater <br /> |

| Returns ||
|---|---|
| `https://developer.android.com/reference/android/os/GpuHeadroomParams.Builder` | This value cannot be `null`. <br /> |

| Throws ||
|---|---|
| `https://developer.android.com/reference/java/lang/IllegalArgumentException` | if the window is invalid. |
