FeatureInfo

Kotlin |Java

public class FeatureInfo
extends Object implements Parcelable

java.lang.Object
↳	android.content.pm.FeatureInfo

Definition of a single optional hardware or software feature of an Android device.

This object is used to represent both features supported by a device and features requested by an app. Apps can request that certain features be available as a prerequisite to being installed through the uses-feature tag in their manifests.

Starting in Build.VERSION_CODES.N, features can have a version, which must always be backwards compatible. That is, a device claiming to support version 3 of a specific feature must support apps requesting version 1 of that feature.

Summary

Constants
`int`	`FLAG_REQUIRED` Set on `flags` if this feature has been required by the application.
`int`	`GL_ES_VERSION_UNDEFINED` Default value for `reqGlEsVersion`;

Inherited constants

From interface android.os.Parcelable

`int`	`CONTENTS_FILE_DESCRIPTOR` Descriptor bit used with `describeContents()`: indicates that the Parcelable object's flattened representation includes a file descriptor.
`int`	`PARCELABLE_WRITE_RETURN_VALUE` Flag for use with `writeToParcel(Parcel, int)`: the object being written is a return value, that is the result of a function such as "`Parcelable someFunction()`", "`void someFunction(out Parcelable)`", or "`void someFunction(inout Parcelable)`".

Fields
`public static final Creator<FeatureInfo>`	`CREATOR`
`public int`	`flags` Additional flags.
`public String`	`name` The name of this feature, for example "android.hardware.camera".
`public int`	`reqGlEsVersion` The GLES version used by an application.
`public int`	`version` If this object represents a feature supported by a device, this is the maximum version of this feature supported by the device.

Public constructors
`FeatureInfo()`
`FeatureInfo(FeatureInfo orig)`

Public methods
`int`	`describeContents()` Describe the kinds of special objects contained in this Parcelable instance's marshaled representation.
`String`	`getGlEsVersion()` This method extracts the major and minor version of reqGLEsVersion attribute and returns it as a string.
`String`	`toString()` Returns a string representation of the object.
`void`	`writeToParcel(Parcel dest, int parcelableFlags)` Flatten this object in to a Parcel.

Inherited methods

From class


        
          java.lang.Object

`Object`	`clone()` Creates and returns a copy of this object.
`boolean`	`equals(Object obj)` Indicates whether some other object is "equal to" this one.
`void`	`finalize()` Called by the garbage collector on an object when garbage collection determines that there are no more references to the object.
`final Class<?>`	`getClass()` Returns the runtime class of this `Object`.
`int`	`hashCode()` Returns a hash code value for the object.
`final void`	`notify()` Wakes up a single thread that is waiting on this object's monitor.
`final void`	`notifyAll()` Wakes up all threads that are waiting on this object's monitor.
`String`	`toString()` Returns a string representation of the object.
`final void`	`wait(long timeoutMillis, int nanos)` Causes the current thread to wait until it is awakened, typically by being notified or interrupted, or until a certain amount of real time has elapsed.
`final void`	`wait(long timeoutMillis)` Causes the current thread to wait until it is awakened, typically by being notified or interrupted, or until a certain amount of real time has elapsed.
`final void`	`wait()` Causes the current thread to wait until it is awakened, typically by being notified or interrupted.

From interface


        
          android.os.Parcelable

`abstract int`	`describeContents()` Describe the kinds of special objects contained in this Parcelable instance's marshaled representation.
`abstract void`	`writeToParcel(Parcel dest, int flags)` Flatten this object in to a Parcel.

Constants

FLAG_REQUIRED

Added in API level 5

public static final int FLAG_REQUIRED

Set on flags if this feature has been required by the application.

Constant Value: 1 (0x00000001)

GL_ES_VERSION_UNDEFINED

Added in API level 5

public static final int GL_ES_VERSION_UNDEFINED

Default value for reqGlEsVersion;

Constant Value: 0 (0x00000000)

Fields

CREATOR

Added in API level 5

public static final Creator<FeatureInfo> CREATOR

flags

Added in API level 5

public int flags

Additional flags. May be zero or more of FLAG_REQUIRED.

name

Added in API level 5

public String name

The name of this feature, for example "android.hardware.camera". If this is null, then this is an OpenGL ES version feature as described in reqGlEsVersion.

reqGlEsVersion

Added in API level 5

public int reqGlEsVersion

The GLES version used by an application. The upper order 16 bits represent the major version and the lower order 16 bits the minor version. Only valid if name is null.

version

Added in API level 24

public int version

If this object represents a feature supported by a device, this is the maximum version of this feature supported by the device. The device implicitly supports all older versions of this feature.

If this object represents a feature requested by an app, this is the minimum version of the feature required by the app.

When a feature version is undefined by a device, it's assumed to be version 0.

Public constructors

FeatureInfo

Added in API level 5

public FeatureInfo ()

FeatureInfo

Added in API level 5

public FeatureInfo (FeatureInfo orig)

Parameters
`orig`	`FeatureInfo`

Public methods

describeContents

Added in API level 5

public int describeContents ()

Describe the kinds of special objects contained in this Parcelable instance's marshaled representation. For example, if the object will include a file descriptor in the output of writeToParcel(android.os.Parcel, int), the return value of this method must include the CONTENTS_FILE_DESCRIPTOR bit.

Returns
`int`	a bitmask indicating the set of special object types marshaled by this Parcelable object instance. Value is either `0` or `CONTENTS_FILE_DESCRIPTOR`

getGlEsVersion

Added in API level 5

public String getGlEsVersion ()

This method extracts the major and minor version of reqGLEsVersion attribute and returns it as a string. Say reqGlEsVersion value of 0x00010002 is returned as 1.2

Returns
`String`	String representation of the reqGlEsVersion attribute

toString

Added in API level 5

public String toString ()

Returns a string representation of the object.

Returns
`String`	a string representation of the object.

writeToParcel

Added in API level 5

public void writeToParcel (Parcel dest, 
                int parcelableFlags)

Flatten this object in to a Parcel.

Parameters
`dest`	`Parcel`: The Parcel in which the object should be written. This value cannot be `null`.
`parcelableFlags`	`int`: Additional flags about how the object should be written. May be 0 or `Parcelable.PARCELABLE_WRITE_RETURN_VALUE`. Value is either `0` or a combination of `Parcelable.PARCELABLE_WRITE_RETURN_VALUE`, and android.os.Parcelable.PARCELABLE_ELIDE_DUPLICATES
