This API is not generally intended for third party application developers. Use the AndroidX Media3 session Library for consistent behavior across all devices.
 Define a command that a MediaController2 can send to a MediaSession2.
 
 If getCommandCode() isn't COMMAND_CODE_CUSTOM), it's predefined command.
 If getCommandCode() is COMMAND_CODE_CUSTOM), it's custom command and
 getCustomAction() shouldn't be null.

Constants
COMMAND_CODE_CUSTOM
public static final int COMMAND_CODE_CUSTOM
Command code for the custom command which can be defined by string action in the
 Session2Command.
Constant Value: 0 (0x00000000)
Fields
Public constructors
Session2Command
public Session2Command (int commandCode)
Constructor for creating a command predefined in AndroidX media2.
| Parameters | |
|---|---|
| commandCode | int: A command code for a command predefined in AndroidX media2. | 
Session2Command
public Session2Command (String action, Bundle extras)
Constructor for creating a custom command.
| Parameters | |
|---|---|
| action | String: The action of this custom command.
 This value cannot benull. | 
| extras | Bundle: An extra bundle for this custom command.
 This value may benull. | 
Public methods
describeContents
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 0orCONTENTS_FILE_DESCRIPTOR | 
equals
public boolean equals (Object obj)
Indicates whether some other object is "equal to" this one.
 The equals method implements an equivalence relation
 on non-null object references:
 
- It is reflexive: for any non-null reference value
     x,x.equals(x)should returntrue.
- It is symmetric: for any non-null reference values
     xandy,x.equals(y)should returntrueif and only ify.equals(x)returnstrue.
- It is transitive: for any non-null reference values
     x,y, andz, ifx.equals(y)returnstrueandy.equals(z)returnstrue, thenx.equals(z)should returntrue.
- It is consistent: for any non-null reference values
     xandy, multiple invocations ofx.equals(y)consistently returntrueor consistently returnfalse, provided no information used inequalscomparisons on the objects is modified.
- For any non-null reference value x,x.equals(null)should returnfalse.
An equivalence relation partitions the elements it operates on into equivalence classes; all the members of an equivalence class are equal to each other. Members of an equivalence class are substitutable for each other, at least for some purposes.
| Parameters | |
|---|---|
| obj | Object: This value may benull. | 
| Returns | |
|---|---|
| boolean | trueif this object is the same as the obj
          argument;falseotherwise. | 
getCommandCode
public int getCommandCode ()
Gets the command code of a predefined command.
 This will return COMMAND_CODE_CUSTOM for a custom command.
| Returns | |
|---|---|
| int | |
getCustomAction
public String getCustomAction ()
Gets the action of a custom command.
 This will return null for a predefined command.
| Returns | |
|---|---|
| String | |
getCustomExtras
public Bundle getCustomExtras ()
Gets the extra bundle of a custom command.
 This will return null for a predefined command.
| Returns | |
|---|---|
| Bundle | |
hashCode
public int hashCode ()
Returns a hash code value for the object. This method is
 supported for the benefit of hash tables such as those provided by
 HashMap.
 
 The general contract of hashCode is:
 
- Whenever it is invoked on the same object more than once during
     an execution of a Java application, the hashCodemethod must consistently return the same integer, provided no information used inequalscomparisons on the object is modified. This integer need not remain consistent from one execution of an application to another execution of the same application.
- If two objects are equal according to the equalsmethod, then calling thehashCodemethod on each of the two objects must produce the same integer result.
- It is not required that if two objects are unequal
     according to the equalsmethod, then calling thehashCodemethod on each of the two objects must produce distinct integer results. However, the programmer should be aware that producing distinct integer results for unequal objects may improve the performance of hash tables.
| Returns | |
|---|---|
| int | a hash code value for this object. | 
writeToParcel
public void writeToParcel (Parcel dest, int flags)
Flatten this object in to a Parcel.
| Parameters | |
|---|---|
| dest | Parcel: This value cannot benull. | 
| flags | int: Additional flags about how the object should be written.
 May be 0 orParcelable.PARCELABLE_WRITE_RETURN_VALUE.
 Value is either0or a combination ofParcelable.PARCELABLE_WRITE_RETURN_VALUE, and android.os.Parcelable.PARCELABLE_ELIDE_DUPLICATES |
