The backup service of Android allows you to copy persistent application data to remote "Cloud" storage, so as to provide a restore point for application data and settings. If you restore the factory settings or convert the application to a new Android device, the system automatically restores the backup data when the application is re-installed. In this way, the user does not need to copy the data or set the previous data. This process is completely transparent to users and does not affect funct

3.3 Particle particleParticle system scripts can be used as templates to create multiple particle systems at run timeThe particle system script is loaded at initialization and defaults to the '. Particle ' file under all public resource locations (root::addresourcelocation). You can load the file type of the custom extension by using the Particlesystemmanager::getsingleton (). Parseallsources method, or by Particlesystemmanager:: Getsingleton (). Parsescript parsing a single script fileExample:P

Title Link: http://poj.org/problem?id=1106DescriptionIn a wireless network with multiple transmitters sending on the same frequencies, it's often a requirement that signals D On the ' t overlap, or at least that they don ' t conflict. One-of-the-accomplishing this is to restrict a transmitter's coverage area. This problem uses a shielded transmitter the only broadcasts in a semicircle.A transmitter T is loc

Now the industry of mobile payment is very chaotic, there are many legal and competitive payment methods, countless startups, industry giants, banking institutions, joint ventures and so on want to share from this market. In the big companies, the deer dominate the role of the time, consumers must wait for the change and patience. In the past few years, we have seen Square, Google, Intuit and other companies have issued a unique e-wallet. While mobile payments are the highlight of this year's C

When we develop the app, the application may require the device to support certain features to ensure that the application runs. For example need support phone, NFC. Gyroscope and so on.We can use the Hassystemfeature method of the Packagemanager object to check whether certain features are supported by the current device.The first method:Use code to check if the device supports certain features. This method is better. Because no matter where the app

Objective: To monitor the operation of Nginx and NFS services in the cluster, such as any service exception, send an email to notify the userCondition: 1. Host and the IP address of the sub-machine, hostname has been determined;2. The host and the sub-machine can be free of dense communication, that is, based on key communication (related commands: Ssh-keygen;ssh-copy-id-i web1);Required Files:1. Python Mail sending tool;2. nfc.sh monitor script, monitor Nginx and NFS service status, and call Ma

After introducing the HART protocol physical layer and the HART data link layer, we also elaborate on the HART service. Through these series of explanations, I believe everyone has a certain understanding of the HART Protocol application in the software platform. The last part is about the HART application layer specifications and related languages and commands. HART Protocol application layer Specification 1HARTCommand Common commands: All devices implement these commands. Command number range:

frequency of the finished infrared receiver head when using. The usual carrier frequency for infrared remote control is 38kHz, which is determined by the 455kHz crystal oscillator used by the transmitter. On the transmitter side to the Crystal Oscillator integer division, the frequency division coefficient is generally taken 12, so 455khz÷12≈37.9 khz≈38khz. There are also some remote control system using 3
