android - 在 Android 中使用带有图像附件的 Gmail 通过隐式 Intent 发送邮件？

Question

它很简单但在我的应用程序中产生了问题。我正在使用隐式 Intent 发送电子邮件，并附有图像作为附件。但是下面的代码会产生问题。

File file = new File(path);
Intent emailIntent = new Intent(Intent.ACTION_SEND); 
emailIntent.setType("vnd.android.cursor.dir/email");
emailIntent.putExtra(Intent.EXTRA_EMAIL, new String[]{""}); 
emailIntent.putExtra(Intent.EXTRA_SUBJECT,"Wedding App"); 
emailIntent.putExtra(Intent.EXTRA_TEXT, "Sharing image via email."); 
emailIntent.putExtra(Intent.EXTRA_STREAM, Uri.parse(file.toString()));
startActivity(Intent.createChooser(emailIntent, "Send mail..."));

创建崩溃:

Answer 1

试试下面的代码。

Intent emailIntent = new Intent(android.content.Intent.ACTION_SEND);
emailIntent.setType("png/image");
emailIntent.putExtra(android.content.Intent.EXTRA_EMAIL, new String[] {
                "mail--id" });
emailIntent.putExtra(android.content.Intent.EXTRA_SUBJECT, subject);
emailIntent.putExtra(android.content.Intent.EXTRA_TEXT, message);
Uri uri = Uri.fromFile(new File(Environment
                .getExternalStorageDirectory(), "/saved_images/MyImage.png"));
emailIntent.putExtra(Intent.EXTRA_STREAM, uri);
emailIntent.setType("text/plain");
startActivity(emailIntent);

并且不要忘记在 list 文件中添加以下权限。

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