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.

Public constructors

Builder

public Builder ()

Public methods

addApk

public IncrementalInstallSession.Builder addApk (Path apk, 
                Path signature)

Adds an APK to set of APKs to be installed. The app must be signed with APK Signature Scheme v4.

Parameters
`apk`	`Path`: the apk to install
`signature`	`Path`: the v4 signature of the apk

Returns
`IncrementalInstallSession.Builder`

addExtraArgs

public IncrementalInstallSession.Builder addExtraArgs (String... extraArgs)

Adds extra arguments to pass to the installation. See 'adb shell pm install --help' for available options.

Parameters
`extraArgs`	`String`: the extra arguments to pass to the installation

Returns
`IncrementalInstallSession.Builder`

build

public IncrementalInstallSession build ()

Builds and starts the streaming install session.

Returns
`IncrementalInstallSession`

Throws
	if the apk or signature file are not able to be read or are invalid.

setAllowReinstall

public IncrementalInstallSession.Builder setAllowReinstall (boolean reinstall)

Sets whether re-install of an app should be performed.

Parameters
`reinstall`	`boolean`: whether re-install of an app should be performed

Returns
`IncrementalInstallSession.Builder`

setBlockFilter

public IncrementalInstallSession.Builder setBlockFilter (IBlockFilter filter)

Sets the callback used to determine whether a block of data that must be delivered to the device should be sent to the device.

Parameters
`filter`	`IBlockFilter`: the callback

Returns
`IncrementalInstallSession.Builder`

setBlockTransformer

public IncrementalInstallSession.Builder setBlockTransformer (IBlockTransformer transformer)

Sets the callback used to transform the block of data before sending.

Parameters
`transformer`	`IBlockTransformer`: the callback

Returns
`IncrementalInstallSession.Builder`

setLogger

public IncrementalInstallSession.Builder setLogger (ILogger logger)

Sets the logger interface used to log errors, warnings, and information regarding the incremental install session.

Parameters
`logger`	`ILogger`: the callback

Returns
`IncrementalInstallSession.Builder`

setResponseTimeout

public IncrementalInstallSession.Builder setResponseTimeout (long timeout, 
                TimeUnit maxTimeUnits)

Sets the maximum amount of time during which no response from the device is allowed when invoking IncrementalInstallSession.waitForInstallCompleted(long, TimeUnit) and IncrementalInstallSession.waitForServingCompleted(long, TimeUnit).

Parameters
`timeout`	`long`: the maximum amount of time during which no response from the device is allowed. A value of 0 allows the specified methods to wait indefinitely for the next response from the device
`maxTimeUnits`	`TimeUnit`: units for non-zero `timeout`

Returns
`IncrementalInstallSession.Builder`
