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.

NativeAllocationInfo

public class NativeAllocationInfo
extends Object

java.lang.Object
↳	com.android.tradefed.device.server.NativeAllocationInfo

Stores native allocation information.

Contains number of allocations, their size and the stack trace.

Note: the ddmlib does not resolve the stack trace automatically. While this class provides storage for resolved stack trace, this is merely for convenience.

`String`	`END_STACKTRACE_KW`
`String`	`SIZE_KW`
`String`	`TOTAL_SIZE_KW`

Public constructors
`NativeAllocationInfo(int size, int allocations)` Constructs a new `NativeAllocationInfo`.

Public methods
`void`	`addStackCallAddress(long address)` Adds a stack call address for this allocation.
`boolean`	`equals(Object obj)` Indicates whether some other object is "equal to" this one.
`int`	`getAllocationCount()` Returns the allocation count.
`NativeStackCallInfo`	`getRelevantStackCallInfo()` Returns the first `NativeStackCallInfo` that is relevant.
	`getResolvedStackCall()` Returns the resolved stack call.
`int`	`getSize()` Returns the size of this allocation.
	`getStackCallAddresses()` Returns the stack call of this allocation as raw addresses.
`int`	`hashCode()`
`boolean`	`isStackCallResolved()` Returns whether the stack call addresses have been resolved into `NativeStackCallInfo` objects.
`boolean`	`isZygoteChild()` Returns whether the allocation happened in a child of the zygote process.
`void`	`setResolvedStackCall( resolvedStackCall)` Sets the resolved stack call for this allocation.
`boolean`	`stackEquals(NativeAllocationInfo mi)`
`String`	`toString()` Returns a string representation of the object.

Public constructors

NativeAllocationInfo

public NativeAllocationInfo (int size, 
                int allocations)

Constructs a new NativeAllocationInfo.

Parameters
`size`	`int`: The size of the allocations.
`allocations`	`int`: the allocation count

Public methods

addStackCallAddress

public void addStackCallAddress (long address)

Adds a stack call address for this allocation.

Parameters
`address`	`long`: The address to add.

equals

public boolean equals (Object obj)

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

Parameters
`obj`	`Object`: the reference object with which to compare.

Returns
`boolean`	`true` if this object is equal to the obj argument; `false` otherwise.

See also:

Object.equals(java.lang.Object)

getAllocationCount

public int getAllocationCount ()

Returns the allocation count.

Returns
`int`

getRelevantStackCallInfo

public NativeStackCallInfo getRelevantStackCallInfo ()

Returns the first NativeStackCallInfo that is relevant.

A relevant NativeStackCallInfo is a stack call that is not deep in the lower level of the libc, but the actual method that performed the allocation.

Returns
`NativeStackCallInfo`	a `NativeStackCallInfo` or `null` if the stack call has not been processed from the raw addresses.

See also:

getResolvedStackCall

public  getResolvedStackCall ()

Returns the resolved stack call.

Returns
	An array of `NativeStackCallInfo` or `null` if the stack call was not resolved.

See also:

getSize

public int getSize ()

Returns the size of this allocation.

Returns
`int`

getStackCallAddresses

public  getStackCallAddresses ()

Returns the stack call of this allocation as raw addresses.

Returns
	the list of addresses where the allocation happened.

hashCode

public int hashCode ()

Returns
`int`

isStackCallResolved

public boolean isStackCallResolved ()

Returns whether the stack call addresses have been resolved into NativeStackCallInfo objects.

Returns
`boolean`

isZygoteChild

public boolean isZygoteChild ()

Returns whether the allocation happened in a child of the zygote process.

Returns
`boolean`

setResolvedStackCall

public void setResolvedStackCall ( resolvedStackCall)

Sets the resolved stack call for this allocation.

If resolvedStackCall is non null then isStackCallResolved() will return true after this call.

Parameters
`resolvedStackCall`	: The list of `NativeStackCallInfo`.

stackEquals

public boolean stackEquals (NativeAllocationInfo mi)

Parameters
`mi`	`NativeAllocationInfo`

Returns
`boolean`

toString

public String toString ()

Returns a string representation of the object.

Returns
`String`

Object.toString()
