statistics, such as non-essential operations, can be in sufficient power or connected to the WiFi, reference Jobscheduler.(4) Streamline redundant services (service)to avoid power consumption for a long time.(5) Attention to the acquisition of positioning information, the use of timely closure.Battery optimization is not difficult, but needs to be very familiar with the business, to understand some of the use of power consumption, timely optimization
total power consumption is reduced.
Of course, we can even delay the request task until the mobile phone network is switched to WiFi, and the mobile phone is recharged and then executed. In the previous description, we encountered a problem: how to delay network requests and execute them in batches. Fortunately, Android provides JobScheduler to help us achieve this goal.1.2) how to transmit network data

However, setting a timeout setting is not enough to solve the problem. For example, how long is the timeout setting more appropriate? When can I retry?
Resolved: To solve the problem above, the correct method may be to use an inaccurate timer. Generally, we will set a time for an operation, but it may be better to modify it dynamically.
For example, if another program needs to wake up five minutes later than the time you set,

Then the mobile security problem is connected to irresolute, which is mainly divided into mobile network security and client application security.

On the other hand, the neural network API was introduced in Android 8.1 to speed up machine learning on Android devices. Android P expands and improves these APIs, adding support for 9 operations, namely pad, batchtospacend, spacetobatchnd, transpose, strided Slice, Mean, Div, Sub and squeeze. After Android p, the

For example: Producer data production is higher than maxrate, the current cluster processing capacity is higher than maxrate, which will lead to the reduction of resource utilization and so on.

the service engine framework. The service engine draws on the "businessdelegate" pattern in corej2ee pattern.After the calling program invokes the service through the Service engine framework, the service engine first extracts the parameters of the calling service and constructs the context of the service invocation. Then choose the right dispatcher, it is actually businessdelegate. He chooses the right engine to perform the service. OFBiz will first determine if the service is "special", such

If there is an input, there must be an output. If there is no output, all the previous actions are meaningless. How can we bind these inputs to the output? The solution to this problem depends on dstreamgraph, which records the input stream and output stream.

problem, the correct way may be to use a non-precision timer. Normally, we set a time to do something, but it might be better to change the time dynamically. For example, if you have another program that needs to wake up 5 minutes later than the time you set, it's best to wait until that time when the two task bundles work together simultaneously, which is how the non-precision timer works at its core. We can customize the scheduled tasks, but if the system detects a better time, it can postpon
