| Name | Description |
|---|---|
| ImportFileAsync(Int32, ParcelFileDescriptor) |
Runs ImportFile(Int32, ParcelFileDescriptor) on a thread-pool thread. |
| ImportFileAsync(Int32, String) |
Runs ImportFile(Int32, String) on a thread-pool thread. |
ImportFileAsync(Int32, ParcelFileDescriptor)
Runs ImportFile(Int32, ParcelFileDescriptor) on a thread-pool thread.
public System.Threading.Tasks.Task<bool> ImportFileAsync(int objectHandle, Android.OS.ParcelFileDescriptor descriptor);member this.ImportFileAsync : int * Android.OS.ParcelFileDescriptor -> System.Threading.Tasks.Task<bool>Parameters
- objectHandle
- Int32
The handle of the object to read from the device.
- descriptor
- ParcelFileDescriptor
The destination file descriptor. Keep it open until the task completes, then close it when it is no longer needed. This operation does not close it.
Returns
A task whose result is the Boolean returned by ImportFile(Int32, ParcelFileDescriptor). A result of true does not confirm that all destination writes succeeded. A failed or short write can leave an incomplete file even when the result is true.
Remarks
This limitation is verified in MtpDevice.cpp in Android 16 (android-16.0.0_r1): readData records destination write errors but returns whether the MTP response is OK.
