Constants
ERROR_BUSY
public static final int ERROR_BUSY
The system is too busy to handle the request.
This error is transient. Applications should consider retrying the operation after a short delay, potentially using an exponential backoff strategy.
Constant Value: 1 (0x00000001)
ERROR_DISK_FULL
public static final int ERROR_DISK_FULL
The operation failed because the disk is full.
This error is potentially transient if the user clears enough space on the storage device.
Constant Value: 6 (0x00000006)
ERROR_INVALID_REQUEST
public static final int ERROR_INVALID_REQUEST
The system cannot fulfill the request as configured.
This error is permanent as it indicates a malformed or invalid request.
Constant Value: 2 (0x00000002)
ERROR_NONE
public static final int ERROR_NONE
Successful operation.
Constant Value: -1 (0xffffffff)
ERROR_PERMISSION_DENIED
public static final int ERROR_PERMISSION_DENIED
The operation failed due to missing permissions.
This error is permanent unless the user manually grants the required permissions.
Constant Value: 5 (0x00000005)
ERROR_UNKNOWN
public static final int ERROR_UNKNOWN
An unknown error.
Constant Value: 0 (0x00000000)
ERROR_UNSUPPORTED_SOURCE
public static final int ERROR_UNSUPPORTED_SOURCE
The source of the operation is unsupported or invalid.
This error is permanent as it indicates an issue with the request.
Constant Value: 3 (0x00000003)
ERROR_UNSUPPORTED_TARGET
public static final int ERROR_UNSUPPORTED_TARGET
The target of the operation is unsupported or invalid.
This error is permanent as it indicates an issue with the request.
Constant Value: 4 (0x00000004)
STATUS_FAILED
public static final int STATUS_FAILED
The operation failed.
Constant Value: 4 (0x00000004)
STATUS_FINISHED
public static final int STATUS_FINISHED
The operation finished successfully.
Constant Value: 3 (0x00000003)
STATUS_IN_PROGRESS
public static final int STATUS_IN_PROGRESS
The operation is currently running.
Constant Value: 2 (0x00000002)
STATUS_QUEUED
public static final int STATUS_QUEUED
The operation is queued and waiting to start.
Constant Value: 1 (0x00000001)
STATUS_UNKNOWN
public static final int STATUS_UNKNOWN
Unknown status.
Constant Value: 0 (0x00000000)
Fields
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(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 |
getErrorCode
public int getErrorCode ()
Returns the error code if the operation failed.
| Returns | |
|---|---|
int | Value is one of the following: |
getErrorMessage
public String getErrorMessage ()
Returns the error message if the operation failed.
| Returns | |
|---|---|
String | This value may be null. |
getFailedPaths
public List<String> getFailedPaths ()
Returns the list of failures.
This list is only populated when the operation reaches a terminal state (STATUS_FINISHED or STATUS_FAILED).
Note: Due to binder transaction limits, this list can truncate the total number of reported failures. If failures occurred, only the first FileManager.getMaxReportedFailures() are reported.
| Returns | |
|---|---|
List<String> | This value cannot be null. |
getRequestId
public String getRequestId ()
Returns the unique ID of the request.
| Returns | |
|---|---|
String | This value cannot be null. |
getSource
public OperationSource getSource ()
Returns the OperationSource that was configured in the original FileOperationRequest.
For example, if an operation was created using a ERROR(/AppDataFileSource) that object would be returned here.
| Returns | |
|---|---|
OperationSource | This value cannot be null. |
getStatus
public int getStatus ()
Returns the current status of the operation.
| Returns | |
|---|---|
int | Value is one of the following: |
getTarget
public OperationTarget getTarget ()
Returns the target of the file operation.
| Returns | |
|---|---|
OperationTarget | This value may be null. |
writeToParcel
public void writeToParcel (Parcel dest, int flags)
Flatten this object in to a Parcel.
| Parameters | |
|---|---|
dest | Parcel: This value cannot be null. |
flags | 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 the following: |
