DownloadRequest

public final class DownloadRequest
extends Object implements Parcelable

java.lang.Object
   ↳ android.telephony.mbms.DownloadRequest


Describes a request to download files over cell-broadcast. Instances of this class should be created by the app when requesting a download, and instances of this class will be passed back to the app when the middleware updates the status of the download.

Summary

Nested classes

class DownloadRequest.Builder

 

Inherited constants

Fields

public static final Creator<DownloadRequest> CREATOR

Public methods

int describeContents()

Describe the kinds of special objects contained in this Parcelable instance's marshaled representation.

boolean equals(Object o)

Indicates whether some other object is "equal to" this one.

Uri getDestinationUri()
String getFileServiceId()
static int getMaxAppIntentSize()

Maximum permissible length for the app's destination path, when serialized via Uri.toString().

static int getMaxDestinationUriSize()

Maximum permissible length for the app's download-completion intent, when serialized via Intent.toUri(int).

Uri getSourceUri()
int getSubscriptionId()
int hashCode()

Returns a hash code value for the object.

byte[] toByteArray()

This method returns a byte array that may be persisted to disk and restored to a DownloadRequest.

void writeToParcel(Parcel out, int flags)

Flatten this object in to a Parcel.

Public methods

describeContents

added in API level 28
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(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.

equals

added in API level 28
public boolean equals (Object o)

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 return true.
  • It is symmetric: for any non-null reference values x and y, x.equals(y) should return true if and only if y.equals(x) returns true.
  • It is transitive: for any non-null reference values x, y, and z, if x.equals(y) returns true and y.equals(z) returns true, then x.equals(z) should return true.
  • It is consistent: for any non-null reference values x and y, multiple invocations of x.equals(y) consistently return true or consistently return false, provided no information used in equals comparisons on the objects is modified.
  • For any non-null reference value x, x.equals(null) should return false.

The equals method for class Object implements the most discriminating possible equivalence relation on objects; that is, for any non-null reference values x and y, this method returns true if and only if x and y refer to the same object (x == y has the value true).

Note that it is generally necessary to override the hashCode method whenever this method is overridden, so as to maintain the general contract for the hashCode method, which states that equal objects must have equal hash codes.

Parameters
o Object: the reference object with which to compare.

Returns
boolean true if this object is the same as the obj argument; false otherwise.

getDestinationUri

added in API level 28
public Uri getDestinationUri ()

Returns
Uri The destination Uri of the downloaded file.

getFileServiceId

added in API level 28
public String getFileServiceId ()

Returns
String The ID of the file service to download from.

getMaxAppIntentSize

added in API level 28
public static int getMaxAppIntentSize ()

Maximum permissible length for the app's destination path, when serialized via Uri.toString().

Returns
int

getMaxDestinationUriSize

added in API level 28
public static int getMaxDestinationUriSize ()

Maximum permissible length for the app's download-completion intent, when serialized via Intent.toUri(int).

Returns
int

getSourceUri

added in API level 28
public Uri getSourceUri ()

Returns
Uri The source URI to download from

getSubscriptionId

added in API level 28
public int getSubscriptionId ()

Returns
int The subscription ID on which to perform MBMS operations.

hashCode

added in API level 28
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 hashCode method must consistently return the same integer, provided no information used in equals comparisons 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 equals(Object) method, then calling the hashCode method 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 equals(java.lang.Object) method, then calling the hashCode method 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.

As much as is reasonably practical, the hashCode method defined by class Object does return distinct integers for distinct objects. (This is typically implemented by converting the internal address of the object into an integer, but this implementation technique is not required by the Java™ programming language.)

Returns
int a hash code value for this object.

toByteArray

added in API level 28
public byte[] toByteArray ()

This method returns a byte array that may be persisted to disk and restored to a DownloadRequest. The instance of DownloadRequest persisted by this method may be recovered via DownloadRequest.Builder.fromSerializedRequest(byte[]).

Returns
byte[] A byte array of data to persist.

writeToParcel

added in API level 28
public void writeToParcel (Parcel out, 
                int flags)

Flatten this object in to a Parcel.

Parameters
out Parcel: The Parcel in which the object should be written.

flags int: Additional flags about how the object should be written. May be 0 or Parcelable.PARCELABLE_WRITE_RETURN_VALUE.
