Effective in 2026, to align with our trunk stable development model and ensure platform stability for the ecosystem, we will publish source code to AOSP in Q2 and Q4. For building and contributing to AOSP, we recommend utilizing android-latest-release instead of aosp-main. The android-latest-release manifest branch will always reference the most recent release pushed to AOSP. For more information, see Changes to AOSP.

LogAssociation

public class LogAssociation
extends Object

java.lang.Object

Public constructors

LogAssociation

public LogAssociation (Invocation invocation, 
                String workUnitId, 
                TestResult testResult, 
                long legacyResultId, 
                LogFile log)

Create an association for a log file. A log file can be associated to an individual test, or to a test run or a module. If a log is associated with a test then a TestReseult object for that test needs to be provided. Otherwise only provide invocation and work unit.

Parameters
`invocation`	`Invocation`: invocation to which the log file belongs to.
`workUnitId`	`String`: work unit id representing the stage of the test that produced the log.
`testResult`	`TestResult`: if a log was produced by a test, testResult object that represents that test.
`legacyResultId`	`long`
`log`	`LogFile`: log file that needs to be associated.

Public methods

equals

public boolean equals (Object o)

Parameters
`o`	`Object`

Returns
`boolean`

getAttemptId

public String getAttemptId ()

Returns attempt id which is required for v2 log upload.

Returns
`String`

getBuildId

public String getBuildId ()

Returns build id. This is required for v2 log upload which needs build info.

Returns
`String`

getBuildTarget

public String getBuildTarget ()

Returns the name of the build target. This is required for v2 log upload.

Returns
`String`

getBuildType

public String getBuildType ()

Returns the build type. This is required for v2 log upload, where build info is required to upload the log. V3 does not need this because that information is already available in invocation.

Returns
`String`

getInvocationId

public String getInvocationId ()

Returns
`String`

getLegacyResultId

public long getLegacyResultId ()

Returns the legacy result id used to upload the log. For backward compatibility the logs are uploaded using V2 version of the api which requires legacy result id. After the log is uploaded we create an associating using the v3 api, using invocation id and work unit id, but we still want the logs to be accessible using the legacy tools which rely on the legacy result id.

Returns
`long`

getLog

public LogFile getLog ()

Returns
`LogFile`

getResourceId

public String getResourceId ()

Returns resource id for the log which uniquely identifies the log on the remote server in this particular invocation.

Returns
`String`

getTestResultId

public String getTestResultId ()

Returns
`String`

getWorkUnitId

public String getWorkUnitId ()

Returns
`String`

hashCode

public int hashCode ()

Returns
`int`

isSupported

public boolean isSupported ()

Returns true if log association is supported for this entry. Logs without resource id do not have a valid association.

Returns
`boolean`

toString

public String toString ()

Returns
`String`
