使用truetime-android第三方库实现

github地址：https://github.com/instacart/truetime-android

配置教程

详见：github的wiki，也可阅读本文实例教程。

Add this to your application’s build.gradle file:

repositories {
    maven {
        url "https://jitpack.io"
    }
}

dependencies {
    // ...
    implementation 'com.github.instacart.truetime-android:library-extension-rx:<release-version>'

    // or if you want the vanilla version of Truetime:
    implementation 'com.github.instacart.truetime-android:library:<release-version>'
}

allprojects {
    repositories {
        google()
        jcenter()
        maven {
            url "https://jitpack.io"
        }
    }

}

dependencies {
    implementation fileTree(dir: 'libs', include: ['*.jar'])
    implementation 'com.android.support:appcompat-v7:28.0.0-rc02'
    implementation 'com.android.support.constraint:constraint-layout:1.1.2'
    implementation 'com.github.instacart.truetime-android:library:3.3'
}

Importing ‘com.github.instacart.truetime-android:library:‘ should be sufficient for this.

Then you must initialize it in onCreate() in your class that extendsandroid.app.Application.

1
TrueTime.build().initialize();

例子：

APP.java

public class App extends Application {
    @Override
    public void onCreate() {
        super.onCreate();

        new Thread(new Runnable() {
            @Override
            public void run() {
                try {
                    TrueTime.build().withNtpHost("time.ustc.edu.cn").initialize();
                } catch (IOException e) {
                    e.printStackTrace();
                }
            }
        }).start();

    }
}

将APP.java添加到AndroidManifest.xml

<application
	android:name=".App"
</application>

使用Date noReallyThisIsTheTrueDateAndTime = TrueTime.now();来获取网络时间。
