android - How to include email recipient information in intents on Android 12?

Question

Ive been using the recommended way to populate an email intent since the early days of Android. This includes recipient, subject, and body text.

On Android 12 however - the recipient field is always left out when doing this, everything else works exactly the same.

Whats is the issue here? Is this a bug in the OS? Im testing with gmail by default, but the same thing applies to other email clients, still only on Android 12.

private fun createIntent(
    metadata: String
): Intent {
    val uri = Uri.parse("mailto:")

    return Intent(ACTION_SENDTO)
        .setData(uri)
        .putExtra(
            EXTRA_EMAIL,
            arrayOf("example@gmail.com") //Ive also tried without arrayOf, no difference.
        )
        .putExtra(
            EXTRA_SUBJECT,
            "Feedback"
        )
        .putExtra(
            EXTRA_TEXT,
            metadata
        )
}

似乎与块ACTION_SEND结合使用可以解决问题。selector这适用于所有 API 级别，直到 API 21。我让其他人解释为什么会这样，但重要的是它有效。

private fun createIntent(
    metadata: String
): Intent {
    return Intent(ACTION_SEND)
        .putExtra(
            EXTRA_EMAIL,
            arrayOf(EMAIL)
        )
        .putExtra(
            EXTRA_SUBJECT,
            TITLE
        )
        .putExtra(
            EXTRA_TEXT,
            metadata
        )
        .apply {
            selector = Intent(ACTION_SENDTO).setData(Uri.parse("mailto:"))
        }
}
