android - 即使文件大小非常小，也会出现 TransactionTooLargeException

Question

尝试共享图像文件时，我不断收到此错误:

java.lang.RuntimeException:android.os.TransactionTooLargeException:数据包大小1085992字节

我认为解决这个问题的方法是进一步压缩图像，从而减小尺寸。这是完成这项工作的函数:

 public static File saveBitmaptoFile(Bitmap bitmap, File pictureFile) {
    FileOutputStream out = null;
    try {
        out = new FileOutputStream(pictureFile);

        // on the next line I'm trying compress the heck out of image.
        bitmap.compress(Bitmap.CompressFormat.JPEG, 1, out);
    } catch (Exception e) {
        e.printStackTrace();
    } finally {
        try {
            if (out != null) {
                out.close();
            }
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
    return pictureFile;
}

这是分享功能:

 private void shareToInstagram() {
        String type = "image/png";
        Intent share = new Intent(Intent.ACTION_SEND);
       //saveBitmpatoFile saves an extremely small and compressed file about 5kb in size

        File pictureFile = ImageUtil.saveBitmaptoFile(photo, ImageUtil.getOutputMediaFile());
        Uri imgUri = FileProvider.getUriForFile(mContext,"com.mycompany.myapp", pictureFile);

        share.setType(type);
        share.putExtra(Intent.EXTRA_STREAM, imgUri);
        mContext.startActivity(Intent.createChooser(share, "Share to"));
    }

我不明白，即使对图片文件应用了如此极端的压缩，TransactionTooLarge 错误仍然会抛出，表示包裹大小实际上没有改变一点。更重要的是，当我选择通过 gmail 共享文件时，我可以看到文件大小为 5kb；我的缓冲区大小远低于文档中 1000kb 的缓冲区大小!有人知道什么可能导致此错误仍然被抛出吗？

Answer 1

因此，解决此 TransactionTooLarge 异常的 final方法是识别具有其从属 fragment 、 View 等的 Activity，将数据包添加到 bundle 中。然后我在上述 Activity 中运行了这段代码:

@Override
protected void onSaveInstanceState(Bundle outState) {
    super.onSaveInstanceState(outState);
    //Clear the Activity's bundle of the subsidiary fragments' bundles.
    outState.clear();
}

这为我解决了这个问题。希望这可以帮助那里的人!
