android studio邮件,Android Studio mailto Intent doesn't show subject and mail body

问题

I'm trying to send an e-mail from my Android App. With the click on a button, gmail should open and show a new email with my previously defined recipient, subject and email body. So far I've tried sending the Intent.ACTION_VIEW as well as Intent.ACTION_SENDTO. Both show my draft with the recipient only. Both subject and message are being opressed. Weird thing is when using the emulator, it works just fine. Also was trying to lock at the android errorlog. Seems like i don't have permission. Is it really a permission problem or could it be something else?

I'd really appreciate any help

cheers

Here is my code:

sending email via ACTION_VIEWIntent intent = new Intent(Intent.ACTION_VIEW, Uri.parse("mailto:" + to));

intent.putExtra(intent.EXTRA_SUBJECT, subject);

intent.putExtra(intent.EXTRA_TEXT, message);

mainActivity.startActivity(intent);

sending email via ACTION_SENDTOIntent email = new Intent(Intent.ACTION_SENDTO);

email.setType("message/rfc822");

email.putExtra(Intent.EXTRA_EMAIL, new String[]{to});

email.putExtra(Intent.EXTRA_SUBJECT, subject);

email.putExtra(Intent.EXTRA_TEXT, message);

mainActivity.startActivity(Intent.createChooser(email, "Choose an Email client :"));

回答1:

try out this code, it worked for me.

Intent intent = new Intent(Intent.ACTION_SENDTO);

intent.setData(Uri.parse("mailto:")); // only email apps should handle this

intent.putExtra(Intent.EXTRA_EMAIL, new String[]{email});

intent.putExtra(Intent.EXTRA_SUBJECT, "Subject here");

intent.putExtra(Intent.EXTRA_TEXT,"Body Here");

if (intent.resolveActivity(getPackageManager()) != null) {

startActivity(intent);

}

also add intent filter in android manifest.

I think we had the same issue. Android API 29 introduced some improvements about sending data to other apps. See more details here: Sending simple data to other apps

Here is the solution that works for me.

Intent selectorIntent = new Intent(Intent.ACTION_SENDTO);

selectorIntent.setData(Uri.parse("mailto:"));

final Intent emailIntent = new Intent(Intent.ACTION_SEND);

emailIntent.putExtra(Intent.EXTRA_EMAIL, new String[]{"address@mail.com"});

emailIntent.putExtra(Intent.EXTRA_SUBJECT, "The subject");

emailIntent.putExtra(Intent.EXTRA_TEXT, "The email body");

emailIntent.setSelector( selectorIntent );

activity.startActivity(Intent.createChooser(emailIntent, "Send email..."));

In few words, with this you are asking for the Android standard app chooser and, in addition, you specify that you want to send an email. So, as result, email clients will appear only.

If user has one email client installed only, the intent will redirect to it instantly.

Hope this helps you too.

try this code

val emailIntent = Intent(Intent.ACTION_SEND)

emailIntent.setType("text/plain")

emailIntent.putExtra(Intent.EXTRA_EMAIL, arrayOf("jon@example.com"))

emailIntent.putExtra(Intent.EXTRA_SUBJECT, "Email subject")

emailIntent.putExtra(Intent.EXTRA_TEXT, "Email message text")

val packageManager = packageManager

val activities = packageManager.queryIntentActivities(emailIntent, 0)

val isIntentSafe = activities.size > 0

if (isIntentSafe) {

startActivity(emailIntent);

}else{

Log.d("MainActivty","Email App not installed");

}

Our old code for emails stopped working some days ago.

It was the following:

public static void shareTextToEmail(Context context, String[] email, String subject, String text)

Intent emailIntent = new Intent(Intent.ACTION_SENDTO, Uri.parse("mailto:" + TextUtils.join(",", email)));

emailIntent.putExtra(Intent.EXTRA_EMAIL, email);

emailIntent.putExtra(Intent.EXTRA_SUBJECT, subject);

emailIntent.putExtra(Intent.EXTRA_TEXT, text);

try {

context.startActivity(Intent.createChooser(emailIntent, context.getString(R.string.share_email_title)));

} catch (android.content.ActivityNotFoundException e) {

Toast.makeText(context, context.getString(R.string.share_no_intent_handler_found), Toast.LENGTH_SHORT).show();

}

}

I've adopted it according to the Zak.Antonio answer:

public static void shareTextToEmail(Context context, String[] email, String subject, String text)

Intent selectorIntent = new Intent(Intent.ACTION_SENDTO);

selectorIntent.setData(Uri.parse("mailto:"));

final Intent emailIntent = new Intent(Intent.ACTION_SEND);

emailIntent.putExtra(Intent.EXTRA_EMAIL, email);

emailIntent.putExtra(Intent.EXTRA_SUBJECT, subject);

emailIntent.putExtra(Intent.EXTRA_TEXT, text);

emailIntent.setSelector(selectorIntent);

try {

context.startActivity(Intent.createChooser(emailIntent, context.getString(R.string.share_email_title)));

} catch (android.content.ActivityNotFoundException e) {

Toast.makeText(context, context.getString(R.string.share_no_intent_handler_found), Toast.LENGTH_SHORT).show();

}

}

The key points are:

Replace Intent.ACTION_SENDTO with Intent.ACTION_SEND in emailIntent

Move Intent.ACTION_SENDTO to a selectorIntent

Do not put emails in intent data, put them only in extras at Intent.EXTRA_EMAIL
