我正在使用Download Manger下载一些多媒体文件并对其进行分类.我也在使用Crashlytics,这是一个错误,我经常在不同的设备和Android版本上得到它.我正在寻找你的解决方案/建议!

您可以在下面看到我的代码:

private class DownloadClickListener implements View.OnClickListener {
    @Override
    public void onClick(View view) {
        // Check if download manager available before request
        if (!DownloadHelper.isDownloadManagerAvailable(getActivity())) {
            // Build custom alert dialog
            AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());
            builder.setMessage(R.string.download_manager_disabled);
            builder.setCancelable(false);
            builder.setPositiveButton(R.string.ok, (dialog, which) -> {
                dialog.dismiss();
            });
            // Create and …

我的订单文件夹中的外部存储中有图像，并且我正在尝试使用意图将该图像共享到外部应用程序

File file = new File(Environment.getExternalStorageDirectory().getAbsolutePath()+"/Orders");
String filename = "OrderID.jpg";
File file = new File(file,filename);
  Intent intent = new Intent(Intent.ACTION_SEND);
  intent.setType("image/*");
                intent.setFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
 intent.putExtra(Intent.EXTRA_STREAM,Uri.fromFile(file));
                try {
                     startActivity(intent);
                } catch (android.content.ActivityNotFoundException ex) {

                }

我已授予加载应用程序本身的存储权限，但每次应用程序崩溃时我都会得到

ndroid.os.FileUriExposedException: file:///storage/emulated/0/Orders/OrderID.jpg exposed beyond app through ClipData.Item.getUri()

任何人都可以帮我解决这个问题吗？我在谷歌上关注了很多帖子但没有用

android.os.FileUriExposedException：file.jpg 通过 ClipData.Item.getUri() 暴露在应用程序之外
