    Dimension size = null;
    try {
        size = driver.manage().window().getSize();
    } catch (Exception e) {
        e.printStackTrace();
    }
    Logger.debug(size == null ? "NULL" : size.toString());

Environment

• java client: 6.0.0 (6.0.0-BETA5 works well)
• Appium server: 1.8.1(on Mac) or 1.8.0(on Windows)
• Desktop OS/version: MacOS 10.13.4 or Windows 7
• Node.js: 10.1.0(on Mac) or 8.9.2(on Windows)
• Mobile platform/version under test: iOS 10.3.3(with Mac) or Android 5.1(with Windows)

I have done it incompletely.(Only for the iOS. The problem still exists on Android.)
It happens when I use the driver.switchTo().alert().accept() function(Only for the iOS) to accept a dialog. (Pardon me, I didn't show all the code. )
To solve this, I must add driver.switchTo().defaultContent() before driver.manage().window() to ensure the driver can get the desire window.
Thank you so much. @SrinivasanTarget

@waitshang, switch to native before, getSize only gets the device resolution while in native context, that's why your default content action fixes it, unless your default content is webview.
driver.context("NATIVE_APP");
