android webview 无法加载插件,webView 测试问题，无法检测到 webView 控件

配置：android 5.0 模拟器 +AppiumForWindows-1.3.4.1

这是测试源代码：

```java

import org.junit.After;

import org.junit.Before;

import org.junit.Test;

import org.openqa.selenium.*;

import org.openqa.selenium.remote.CapabilityType;

import org.openqa.selenium.remote.DesiredCapabilities;

import android.webkit.WebView;

import io.appium.java_client.AppiumDriver;

import java.io.File;

import java.net.URL;

import java.util.Set;

public class AndroidWebViewTest {

private AppiumDriver driver;

@Before

public void setUp() throws Exception {

File classpathRoot = new File(System.getProperty("user.dir"));

File appDir = new File(classpathRoot, "apps");

File app = new File(appDir, "WebView.apk");

DesiredCapabilities capabilities = new DesiredCapabilities();

capabilities.setCapability(CapabilityType.BROWSER_NAME, "");

capabilities.setCapability(CapabilityType.PLATFORM, "WINDOWS");

capabilities.setCapability("app", app.getAbsolutePath());

capabilities.setCapability("appPackage", "com.example.webview");

capabilities.setCapability("appActivity", ".MainActivity");

capabilities.setCapability("platformName", "Android");

// capabilities.setCapability("deviceName","HUAWEI G700-U00");

capabilities.setCapability("deviceName","myAVD");

capabilities.setCapability("platformVersion", "21");

driver = new AppiumDriver(new URL("http://127.0.0.1:4723/wd/hub"), capabilities);

}

@Test

public void main(){

Set contextNames = driver.getContextHandles();

System.out.println(contextNames.size());

for (String contextName : contextNames) {

System.out.println(contextName);

if(contextName.contains("WEBVIEW")||contextName.contains("webview")){

driver.context(contextName);

}else{

System.out.println("no WEBVIEW");

}

}

// Thread.sleep(15000);

// driver.context("WEBVIEW");

// System.out.print("CurrentUrl"+driver.getCurrentUrl());

}

@After

public void tearDown() throws Exception {

driver.quit();

}

}

2. 这是打印的结果

```java

NATIVE_APP

no WEBVIEW

这是控制台打屏
