## Public constructors
### InputDriver.Builder
```
InputDriver.Builder ()
```
Constructs a new builder.
| Returns ||
|---|----------------------------------------------------------------------------------------------------------------------------------------------------|
| | A new[InputDriver.Builder](https://developer.android.com/reference/com/google/android/things/userdriver/input/InputDriver.Builder)instance.
|
## Public methods
### build
```
InputDriver build ()
```
Build an[InputDriver](https://developer.android.com/reference/com/google/android/things/userdriver/input/InputDriver). Builds an[InputDriver](https://developer.android.com/reference/com/google/android/things/userdriver/input/InputDriver)with the provided characteristics.
| Returns ||
|---------------------------------------------------------------------------------------------------------------|----------------------------------------------------------------------------------------------------------------------------------|
| [InputDriver](https://developer.android.com/reference/com/google/android/things/userdriver/input/InputDriver) | A new[InputDriver](https://developer.android.com/reference/com/google/android/things/userdriver/input/InputDriver)object.
|
### setAxisConfiguration
```
InputDriver.Builder setAxisConfiguration (int axis,
int min,
int max,
int fuzz,
int flat)
```
Configure an absolute axis supported by this driver. This method should be called for each axis supported.
| Parameters ||
|--------|-------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
| `axis` | `int`: One of the axis constants from[MotionEvent](https://developer.android.com/reference/android/view/MotionEvent.html). Currently only X and Y are supported.
|
| `min` | `int`: An inclusive minimum value of positions on this axis.
|
| `max` | `int`: An inclusive maximum value of positions on this axis.
|
| `fuzz` | `int`: An int to denote the error tolerance of the axis measurements.
|
| `flat` | `int`: An int denoting the extent of the center flat position.
|
| Returns ||
|-------------------------------------------------------------------------------------------------------------------------------|-----------------------------------|
| [InputDriver.Builder](https://developer.android.com/reference/com/google/android/things/userdriver/input/InputDriver.Builder) | The same builder instance.
|
| Throws ||
|--------------------------------------------------------------------------------------------------------|----------------------------------------------|
| [IllegalArgumentException](https://developer.android.com/reference/java/lang/IllegalArgumentException) | if \|axis\| is not supported or max \<= min. |
### setName
```
InputDriver.Builder setName (String name)
```
Set the name of the input driver.
| Parameters ||
|--------|-----------------------------------------------------------------------------------------------------------------------|
| `name` | `String`: A String representing the name of the driver. If a name is not provided, one will be auto-generated.
|
| Returns ||
|-------------------------------------------------------------------------------------------------------------------------------|-----------------------------------|
| [InputDriver.Builder](https://developer.android.com/reference/com/google/android/things/userdriver/input/InputDriver.Builder) | The same builder instance.
|
### setProductId
```
InputDriver.Builder setProductId (int productId)
```
Set the product id for the driver. A product id uniquely identifies which product within the address space of a given vendor, identified by the device's vendor id. A value of 0 will indicates a product id is not available.
| Parameters ||
|-------------|--------------------------------------------------------------------|
| `productId` | `int`: An int representing the input device. Defaults to 0.
|
| Returns ||
|-------------------------------------------------------------------------------------------------------------------------------|-----------------------------------|

|
### setSupportedKeys
```
InputDriver.Builder setSupportedKeys (int[] supportedKeyCodes)
```
Set the keys supported by this driver.
| Parameters ||
|---------------------|----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
| `supportedKeyCodes` | `int`: An array of key codes representing the keys this input driver supports. The codes must be values from[KeyEvent](https://developer.android.com/reference/android/view/KeyEvent.html).
|
| Returns ||
|-------------------------------------------------------------------------------------------------------------------------------|-----------------------------------|
| [InputDriver.Builder](https://developer.android.com/reference/com/google/android/things/userdriver/input/InputDriver.Builder) | The same builder instance.
|
| Throws ||
|--------------------------------------------------------------------------------------------------------|-------------------------------------------------------|
| [IllegalArgumentException](https://developer.android.com/reference/java/lang/IllegalArgumentException) | if any of the key codes are not recognized key codes. |
### setVendorId
```
InputDriver.Builder setVendorId (int vendorId)
```
Set the vendor id for the driver. A vendor id uniquely identifies the company who manufactured the device. A value of 0 indicates a vendor id is not available.
| Parameters ||
|------------|-------------------------------------------------------------------|
| `vendorId` | `int`: An int representing the vendor code. Defaults to 0.
|
| Returns ||
|-------------------------------------------------------------------------------------------------------------------------------|-----------------------------------|
| [InputDriver.Builder](https://developer.android.com/reference/com/google/android/things/userdriver/input/InputDriver.Builder) | The same builder instance.
