2021-06-21MTP: Skip runtime thumbnail generation for Android HostJames Wei
Android Host is not capable to deal with the long processing time for runtime thumbnail generation. Skip runtime thumbnail generation for Android Host but keep no impact to other Host Bug: 188752500 Test: atest MtpTests Test: atest MtpServerTest Test: atest MtpServiceTests Test: manual test on Windows 10 File Explorer Test: manual test on Android Host Files App Change-Id: I24ed3bb29c5a6912398a9e00e7748fd406cf6a64
2017-04-03Properly guard access to CloseGuard in finalizers.Narayan Kamath
CloseGuard instances are allocated in constructors and usually assigned to final fields. This implies they're non-null in finalizers except in the case where the constructor throws. We add a null check to make sure we can continue cleaning up other state in the finalizer (if applicable). Also, this change decouples closeguard warnings in constructors from other state based logic. This because the logic there is usually duplicated with the call to close(). NOTE: This change is not a "complete" fix. Many of these finalizers are broken in the case where <init> throws. The only objective of this change is to make such errors more obvious. Note that some of these classes don't have CTS tests. Test: make, CtsMediaTestCases. Bug: 35609098 Change-Id: I24d9e0215f80e44914dba8ab99b6312fd6ed1fc0

2016-09-14Do not access MTP devices when disabled.Philip P. Moltmann
The USB data transfer is disabled we should not allow access MTP devices (e.g. usb sticks). We have two ways of accessing them: Either by mounting them or by creating a MTPDevice in an app. Of course an app could implement implement their own MTPDevice implementation. In this case we cannot enforce the policy without completely suppressing all MTP USB devices which would be too restrictive. Note: When the policy is set we do _not_ disconnect already connected MTP devices Fixes: 31472955 Change-Id: I6080c48c49657102774b2b3b4d89ff030245a266

2016-04-18Handle API review comments from the council.Daichi Hirono
* MtpEvent: Remove public constructor since properties cannot be set directly. * MtpEvent: Move event constants from MtpConstants to MtpEvent class. * getPartialObject64: the byte[] must have indices of Integer.MAX_VALUE at most. Document as such. * sendObjectInfo: what happens if the transfer doesn’t succeed? How is the app notified? If there is a reason for the failure communicated, how does the app find this out? Add docs. * Add isOperationSupported(int) and isEventSupported(int) helpers. Change-Id: Ifd80016d2ddd3b66d5c45f6da76b6133f0c9a617 Fixes: 28146379

2016-03-25Add getObjectSizeLong hidden API to MtpDevice class.Daichi Hirono
In the MTP spec, the object size is stored in MtpObjectInfo as unsigned 32-bit integer and fetched by the getObjectInfo operation. For the objects that are more than 4GB, the object size is provided as one of extra properties, which are fetched by different operation. The CL adds to getObjectSizeLong hidden method to Java MtpDevice class so that client code can obtain 4GB+ object size. BUG=27805369 Change-Id: I8a5b85c8db39734f00e49709c61b271eb48ff33d

2014-01-07AArch64: Use long for pointers in MTP classesAshok Bhat
For storing pointers, long is used in MTP classes, as native pointers can be 64-bit. In addition, some minor changes have been done to conform with standard JNI practice (e.g. use of jint instead of int in JNI function prototypes) Change-Id: I67805547251722e7b77611d47d0bb632a64d3e6d Signed-off-by: Ashok Bhat <ashok.bhat@arm.com> Signed-off-by: Marcus Oakland <marcus.oakland@arm.com> Signed-off-by: Kévin PETIT <kevin.petit@arm.com>
