Permissão negada para o anexo do gmail android

Quando eu pressionar o botão, eu quero enviar o arquivo json dentro do dispositivo via e-mail. Quando eu mudar para o Gmail lado, eu recebo o erro "permissão negada para o anexo". Como posso resolver este problema?

manifesto:

    <uses-permission android:name="android.permission.INTERNET" />
    <uses-permission android:name="android.permission.WRITE_INTERNAL_STORAGE" />
    <uses-permission android:name="android.permission.READ_INTERNAL_STORAGE" />
    <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
    <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />

meu código;

 sendgmailButton.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                String filepath = "/data/data/com.example.newgen/files/jsonexample.json";


                        Intent emailIntent = new Intent(android.content.Intent.ACTION_SEND);
                        emailIntent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
                        emailIntent.addFlags(Intent.FLAG_GRANT_WRITE_URI_PERMISSION);
                        emailIntent.setType("application/json");
                         emailIntent.putExtra(android.content.Intent.EXTRA_EMAIL, new String[]
                                {"[email protected]"});
                        emailIntent.putExtra(android.content.Intent.EXTRA_SUBJECT,
                                "Test Subject");
                        emailIntent.putExtra(android.content.Intent.EXTRA_TEXT,
                                "go on read the emails");
               
                        emailIntent.putExtra(Intent.EXTRA_STREAM, Uri.parse("file://"+ filepath));


        
                        startActivity(Intent.createChooser(emailIntent, "Send mail..."));


            }
        });
