Appium 切换上下文环境

Appium 切换上下文环境，代码如下：

    private void switchToContext(String sContext) {
        LogManager.getLogger(this.getClass()).info("Swith to Context: " + sContext);
        Set<String> contextNames = driver.getContextHandles();
        LogManager.getLogger(this.getClass()).info("Exists Contexts: " + contextNames.toString());
        for (String contextName : contextNames) {
            if (contextName.contains(sContext)) {
                driver.context(contextName);
                LogManager.getLogger(this.getClass()).info("Swith to Context SUCCESS.");
                break;
            }
        }
    }
