Bug: 10667740 A3D creates Allocations before knowing the underlying Type (and thus size). Moving the mSize calculation to be conditional for concrete Allocations eliminates the bug. In the future, we could let A3D dynamically update the Allocation size if it is necessary to improve heap behavior. Change-Id: I520246806b6ead0387a1a41372dade1a6e7c2271

/**
|
|
* <p> This class provides the primary method through which data is passed to
|
|
* and from RenderScript kernels. An Allocation provides the backing store for
|
|
* a given {@link android.renderscript.Type}. </p>
|
|
*
|
|
* <p>An Allocation also contains a set of usage flags that denote how the
|
|
* Allocation could be used. For example, an Allocation may have usage flags
|
|
* specifying that it can be used from a script as well as input to a {@link
|
|
* android.renderscript.Sampler}. A developer must synchronize across these
|
|
* different usages using {@link android.renderscript.Allocation#syncAll} in
|
|
* order to ensure that different users of the Allocation have a consistent view
|
|
* of memory. For example, in the case where an Allocation is used as the output
|
|
* of one kernel and as Sampler input in a later kernel, a developer must call
|
|
* {@link #syncAll syncAll(Allocation.USAGE_SCRIPT)} prior to launching the
|
|
* second kernel to ensure correctness.
|
|
*
|
|
* <p>An Allocation can be populated with the {@link #copyFrom} routines. For
|
|
* more complex Element types, the {@link #copyFromUnchecked} methods can be
|
|
* used to copy from byte arrays or similar constructs.</p>
