java - Appium getScreenshotAs() 抛出 java.lang.IllegalStateException：无法压缩回收的位图（Samsung Galaxy A3 2017）

问题描述

public static BufferedImage createScreenshotOfMiddleOfTheElement(final MobileElement element) throws Exception {
    final File screenshotFile = element.getScreenshotAs(OutputType.FILE);
    final BufferedImage screenshot = ImageIO.read(screenshotFile);
    final int width = screenshot.getWidth() / 5;
    final int height = screenshot.getHeight() / 5;
    final int x = width * 2;
    final int y = height * 2;
    return screenshot.getSubimage(x, y, width, height);
}

在上述方法的第一行中，当尝试对该元素进行截图时，Appium 将抛出：

org.openqa.selenium.WebDriverException: An unknown server-side error occurred while processing the command. Original error: java.lang.IllegalStateException: Can't compress a recycled bitmap

到目前为止，代码都能正确执行。可疑的是 - 它只在三星 Galaxy A3 (2017) 上中断。我该如何解决？
