从android应用程序生成csv文件并从android 12开始共享时出现问题

Question

我想制作csv文件，并为用户提供共享该文件的选项。我使用的这段代码在android 12之前一直运行良好，但android 12并没有授予从应用程序保存文件的权限。

          FileOutputStream fileOutputStream = null;
          final File filePath = new 
           File(Environment.getExternalStorageDirectory().toString() + "/excelFile.csv");

    try {
        fileOutputStream = new FileOutputStream(filePath);
        fileOutputStream.write(239);
        fileOutputStream.write(187);
        fileOutputStream.write(191);
        printWriter = new PrintWriter(new OutputStreamWriter(fileOutputStream, StandardCharsets.UTF_8));

        printWriter.println("צד" + ","
                + "קבוצה" + ','
                + "שם" + ","
                + "מס' מוזמנים" + ","
                + "נשלחה הזמנה" + ","
                + "סטטוס הגעה" + ","
                + "טלפון" + ","
                + "כתובת מייל" + ","
                + "סכום מתנה משוער" + ","
                + "הערות" + ","
                + "אירועים קשורים");


        Uri uriForFile = FileProvider.getUriForFile(this, getApplicationContext().getPackageName() + ".share", filePath);
        Intent intent = new Intent("android.intent.action.SEND");
        intent.setType("vnd.android.cursor.dir/email");
        intent.putExtra("android.intent.extra.EMAIL", new String[] 
        {"[e-mail]"});
        intent.putExtra("android.intent.extra.STREAM", uriForFile);
        intent.putExtra("android.intent.extra.SUBJECT", "excelFile");
        startActivity(Intent.createChooser(intent, "send"));
        printWriter.flush();
        printWriter.close();
    } catch (IOException e) {
        e.printStackTrace();
    }

我得到了这个错误：

W/System.err：java.io.FileNotFound异常： /storage/emulated/0/excelFile.csv：打开失败：EACCES（权限被拒绝）
