Question

mImageReader = ImageReader.newInstance(mWidth, mHeight, PixelFormat.RGBA_8888, 4);
mVirtualDisplay = mMediaProjection.createVirtualDisplay(TAG, mWidth, mHeight, mDPI,DisplayManager.VIRTUAL_DISPLAY_FLAG_AUTO_MIRROR, mImageReader.getSurface(), getimg(), null);
image = mImageReader.acquireLatestImage();

我遇到了同样的问题，但不是在我的设备上，而是在我的一位客户身上。我在 this 上发现了一些东西地点。他们使用以下代码:

Image image;
    try {
        image = mImageReader.acquireLatestImage();
    } catch (RuntimeException e) {
        /* In API level 23 or below,  it will throw "java.lang.RuntimeException:
           ImageReaderContext is not initialized" when ImageReader is closed. To make the
           behavior consistent as newer API levels,  we make it return null Image instead.*/
        if (isImageReaderContextNotInitializedException(e)) {
            image = null;
        } else {
            throw e;  // only catch RuntimeException:ImageReaderContext is not initialized
        }
    }
    if (image == null) {
        return null;
    }



private boolean isImageReaderContextNotInitializedException(RuntimeException e) {
    return "ImageReaderContext is not initialized".equals(e.getMessage());
}

我还不知道它是否能解决问题，因为我的设备上没有发生崩溃。让我知道它是否有帮助。
