android_convertGralloc1To0Usage() is used to convert gralloc1_usage(uint64_t) to gralloc_usage (int32_t), then passed as a para in allocateGraphicBuffer(). But definition of allocateGraphicBuffer() is as void CameraAidlTest::allocateGraphicBuffer(uint32_t width, uint32_t height, uint64_t usage, PixelFormat format, buffer_handle_t* buffer_handle). The type of "usage" is uint64_t. So the convert (uint64_t -> int32_t -> uint64_t) will change usages(31 bit is 1) such as 0x0000000080020b00 to 0xffffffff80020b00. It's unexpected. Use ANDROID_NATIVE_UNSIGNED_CAST to fix the issue.
