. There is no leaked cursor information in the log.
Cause analysis:
When mediaprovider receives an external query request, the process of the other program exits, causing the imemememory binder of the passed cursorwindow to be cleared, therefore, when mediaprovider processes query_transaction, it finds that the memory address of the received imemory object is null, and an exception is thrown to Android. media. exit Process.

Occasionally, I am a programmer. Fortunately, I know that there is an adapter. For the above situation, I only need to buy a multi-port card reader (¥10.00) in the supermarket next to it ), the problem is completely solved.
The card reader mentioned above is actually an adapter used.Adapter Mode

Write function size question in Audiotrack
When I saw the audio of the Audiotrack::write function when I looked at the relevant part of "Understanding Android" recently, I had some questions about the size of the operation.
The complete code for the function is as follows:
ssize_t audiotrack::write (const void* buffer, size_t usersize)
{
if (msharedbuffer!= 0) return invalid_operation;
if (mistimed) return invalid_operation;
if (ssize_t (Usersize)
