task A << { println 'Hello from A' } task B << { println 'Hello from B' } B.dependsOn A It is an alternative way to define the dependency instead of using the task name. And the output is the same: > gradle -q B Hello from A Hello from B

import React, { Component } from 'react'; import { AppRegistry, Text } from 'react-native'; class HelloWorldApp extends Component { render() { return ( <Text>Hello world!</Text> ); } } AppRegistry.registerComponent('HelloWorldApp', () => HelloWorldApp); ...

You can add multiple dependencies. task A << { println 'Hello from A' } task B << { println 'Hello from B' } task C << { println 'Hello from C' } task D << { println 'Hello from D' } Now you can define a set of dependencies: B.dependsOn A...

You can add multiple dependencies. task A << { println 'Hello from A' } task B(dependsOn: A) << { println 'Hello from B' } task C << { println 'Hello from C' } task D(dependsOn: ['B', 'C'] << { println 'Hello from D' } The output is: >...

The remote module allows simple RMI (remote method invocation) of main process objects from renderer process. First create the main process in index.js const {app, BrowserWindow} = require('electron') let win = null app.on('ready', () => { win = new BrowserWindow() win.loadURL(`file://...

To install React Router, just run the npm command npm install --save react-router And you're done. This is literally all you have to do to install react router. Please Note : react-router is dependent on react, So make sure you install react as well. To set up: using an ES6 transpiler, like bab...

context.globalCompositeOperation = "destination-over" "destination-over" compositing places new drawing under existing drawings. context.drawImage(rainy,0,0); context.globalCompositeOperation='destination-over'; // sunny UNDER rainy context.drawImage(sunny,0,0);

context.globalCompositeOperation = "destination-out" "destination-out" compositing uses new shapes to erase existing drawings. The new shape is not actually drawn -- it is just used as a "cookie-cutter" to erase existing pixels. context.drawImage(apple,0,0); conte...

context.globalCompositeOperation = "source-over" "source-over" compositing [default], places all new drawings over any existing drawings. context.globalCompositeOperation='source-over'; // the default context.drawImage(background,0,0); context.drawImage(parachuter,0,0); ...

context.globalCompositeOperation = "destination-in" "destination-in" compositing clips existing drawings inside a new shape. Note: Any part of the existing drawing that falls outside the new drawing is erased. context.drawImage(picture,0,0); context.globalCompositeOperation...

context.globalCompositeOperation = "source-in"; source-in compositing clips new drawings inside an existing shape. Note: Any part of the new drawing that falls outside the existing drawing is erased. context.drawImage(oval,0,0); context.globalCompositeOperation='source-in'; // pictu...

There are many reasons a write operation may fail. A frequent one is because your security rules reject the operation, for example because you're not authenticated (by default a database can only be accessed by an authenticated user). You can see these security rule violations in the logcat output....

task A << { println 'Hello from A' } task B << { println 'Hello from B' } B.mustRunAfter A The B.mustRunAfter A line tells Gradle to run task after task specified as an argument. And the output is: > gradle -q B A Hello from A Hello from B The ordering rule d...

Make sure the following dependency is added to your app's build.gradle file under dependencies: compile 'com.android.support:support-core-ui:25.3.0' Then add the ViewPager to your activity layout: <android.support.v4.view.ViewPager android:id="@+id/viewpager" android:layo...

Custom sounds may be provided for notifications generated by your app. When the system displays an alert for a local notification or badges an app icon, it plays this sound (so long as the user has not disabled notification sounds). The default value is nil which means no sound is played for your n...

We're using a toplevel guard in our route config to catch the current user on first page load, and a resolver to store the value of the currentUser, which is our authenticated user from the backend. A simplified version of our implementation looks as follows: Here is our top level route: export c...

This example shows how to advertise a custom payload from a Windows 10 device in the foreground. The payload uses a made up company (identified as 0xFFFE) and advertises the string Hello World in the advertisement. BluetoothLEAdvertisementPublisher publisher = new BluetoothLEAdvertisementPublisher(...

General Listening This example shows how to listen for a specific advertisement. BluetoothLEAdvertisementWatcher watcher = new BluetoothLEAdvertisementWatcher(); // Use active listening if you want to receive Scan Response packets as well // this will have a greater power cost. watcher.Scanni...

CardView provides a default elevation and corner radius so that cards have a consistent appearance across the platforms. You can customize these default values using these attributes in the xml file: card_view:cardElevation attribute add elevation in CardView. card_view:cardBackgroundColor attr...
