Question

我正在尝试发送附带附件的电子邮件。内部存储中的文件，所以这是我的代码：

File filelocation = new File(getFilesDir().getAbsolutePath()+"/MyApp", "FileName");
        Uri path = Uri.fromFile(filelocation);
        Intent emailIntent = new Intent(Intent.ACTION_SEND);
        emailIntent .setType("vnd.android.cursor.dir/email");
        String to[] = {"mailmailmail@gmail.com"};
        emailIntent .putExtra(Intent.EXTRA_EMAIL, to);
        emailIntent .putExtra(Intent.EXTRA_STREAM, path);
        emailIntent .putExtra(Intent.EXTRA_SUBJECT, "Subject");
        startActivity(Intent.createChooser(emailIntent , "Send email..."));

但我总是得到：Permission denied for file。

我该如何解决？

Answer 1

我用这种方式解决了：我将文件复制到外部缓存目录，然后发送。

File temporaryFile = null;
    try {
        temporaryFile = File.createTempFile(keyType.getKeyTypeString(), ".pem", context.getExternalCacheDir() );
        Utils.copy(new File(getFilesDir().getAbsolutePath()+"/"+ Utils.APP_OPERATOR_DIR, keyType.getKeyTypeString()+".pem"), temporaryFile);
    } catch (IOException e) {
        e.printStackTrace();
    }

File filelocation = new File(getFilesDir().getAbsolutePath()+"/MyApp", "FileName");
        Uri path = Uri.fromFile(filelocation);
        Intent emailIntent = new Intent(Intent.ACTION_SEND);
        emailIntent .setType("vnd.android.cursor.dir/email");
        String to[] = {"mailmailmail@gmail.com"};
        emailIntent .putExtra(Intent.EXTRA_EMAIL, to);
        emailIntent .putExtra(Intent.EXTRA_STREAM, path);
        emailIntent .putExtra(Intent.EXTRA_SUBJECT, "Subject");
        startActivity(Intent.createChooser(emailIntent , "Send email..."));

- 确保您已在清单中添加了读取权限

uses-permission android：name =“android.permission.READ_EXTERNAL_STORAGE”。

-GMail 5.0仅接受来自外部存储的文件 Gmail 5.0 app fails with "Permission denied for the attachment" when it receives ACTION_SEND intent

你也可以使用这个库：compile'com.github.yesidlazaro：GmailBackground：1.1'。

    String imagePath = data.getStringExtra(GOTOConstants.IntentExtras.IMAGE_PATH);

    BackgroundMail.newBuilder(ReportBugActivity.this)
            .withUsername("some_email@gmail.com")
            .withPassword("pages123")
            .withMailto("mail_to_email.bugs@gmail.com")
            .withSubject("Android Bug Report")
            .withAttachments(imagePath)
            .withBody("Android Bug Report")
            .withOnSuccessCallback(new BackgroundMail.OnSuccessCallback() {
                @Override
                public void onSuccess() {
                    Toast.makeText(getApplicationContext(), "Email Sent", Toast.LENGTH_LONG).show();

                    finish();
                    startActivity(getIntent());
                }
            })
            .withOnFailCallback(new BackgroundMail.OnFailCallback() {
                @Override
                public void onFail() {
                    Toast.makeText(getApplicationContext(), "Failed", Toast.LENGTH_LONG).show();
                }
            }).send();
