To develop a network-based application on the Android platform, you must determine the current network connection status. The following code, as an example, describes in detail how to judge the current network situation.
First, let's look at a self-defined application class.
Public class networkdetector {
This class has only one static method to check whether the network of the current system is available. If a

The HVR data synchronization software is being tested today. Due to the large data volume (14 MB for one record, containing the lob field and 3000 records) and the IO is poor, as a result, synchronization (specifically HVR refresh) is slo
In awr, "PHYSICAL_MEMORY_BYTES" indicates the available physical memory and physical memory.
Environment: Microsoft Windows x86 64-bit, Oracle Database 11.2.0.1.0, single-host
In awr, the memory displayed by "PHYSICAL_MEMORY_BYTES" is the currently available physical memory.
Note: The current available physical memory is not the sum of the memory size insert
Docker ~ Swarm builds a highly available docker cluster and swarmdocker
Back to directorySwarm Concept
Swarm is a Docker company launched to manage docker clusters. It turns a group of Docker hosts into a single, virtual host. Swarm uses standard Docker API interfaces as its front-end access portals. in other words, various forms of Docker clients (such as docker Client in Go, docker_py, and docker) can communicate directly with Swarm. Almost all Swar
To see which tasks is available for my build we can run Gradle with the command-line option- t or --tasks
