Intent URI to launch Gmail App

Question

Is there any URI which can point to the GMAIL App in android and help me launch it?

Answer 1

This works to intent just the gmail app.

final Intent intent = new Intent(Intent.ACTION_VIEW)
    .setType("plain/text")
    .setData(Uri.parse("[email protected]"))
    .setClassName("com.google.android.gm", "com.google.android.gm.ComposeActivityGmail")
    .putExtra(Intent.EXTRA_EMAIL, new String[]{"[email protected]"})
    .putExtra(Intent.EXTRA_SUBJECT, "test")
    .putExtra(Intent.EXTRA_TEXT, "hello. this is a message sent from my demo app :-)");
startActivity(intent);

use for plenty of emails:

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

for single emails:

intent.setData(Uri.parse("[email protected]"));

You may add extra putExtra(Intent.EXTRA..) and change the setType for your purpose. :P

Update (1/22/14): It is important to note that if you are going to use this code, you check to make sure that the user has the package "com.google.android.gm" installed on their device. In any language, make sure to check for null on specific Strings and initializations.

Answer 2

I'm using this in my apps:

Intent mailClient = new Intent(Intent.ACTION_VIEW);
mailClient.setClassName("com.google.android.gm", "com.google.android.gm.ConversationListActivity");
startActivity(mailClient);

Answer 3

Using package name is not recommended as its an undocumented method. In case if the package name changes some day the code will fail.

Try this code instead

 Intent emailIntent = new Intent(Intent.ACTION_SENDTO, Uri.fromParts(
 "mailto", "[email protected]", null));
 emailIntent.putExtra(Intent.EXTRA_SUBJECT, "This is my subject text");
 context.startActivity(Intent.createChooser(emailIntent, null));

Answer 4

Use this:

Intent intent = getPackageManager().getLaunchIntentForPackage("com.google.android.gm");
startActivity(intent);

This could be device and API level dependent. Use with care.

Answer 5

Simple and 100 % working

Intent intent = new Intent (Intent.ACTION_SEND);
intent.setType("message/rfc822");
intent.putExtra(Intent.EXTRA_EMAIL, new String[]{"[email protected]"});
intent.putExtra(Intent.EXTRA_SUBJECT, "Any subject if you want");
intent.setPackage("com.google.android.gm");
if (intent.resolveActivity(getPackageManager())!=null)
    startActivity(intent);
else
    Toast.makeText(this,"Gmail App is not installed",Toast.LENGTH_SHORT).show();

Answer 6

Try this

i have tried to many solutions but finally i got a correct way that works fine for me

try {
    Intent intent = new Intent (Intent.ACTION_VIEW , Uri.parse("mailto:" + "[email protected]"));
    intent.putExtra(Intent.EXTRA_SUBJECT, "your_subject");
    intent.putExtra(Intent.EXTRA_TEXT, "your_text");
    startActivity(intent);
} catch(Exception e) {
    Toast.makeText(Share.this, "Sorry...You don't have any mail app", Toast.LENGTH_SHORT).show();
    e.printStackTrace(); 
}

Note

• This will open your installed mail application(Email,Gmail) to send mail in which you can select one among them.
• Don't use direct package name like("com.google.android.gm") because in future if they change package name your app will face problems.

Answer 7

Later the requirements changed to starting an "Email app", so the below code basically starts an email app and the user has to choose among the choices shown up.

So, I had to use

Intent intent = new Intent(Intent.ACTION_SEND);
intent.setType("plain/text");
intent.putExtra(Intent.EXTRA_SUBJECT, "Emailing link");
intent.putExtra(Intent.EXTRA_TEXT, "Link is \n" +
        "This is the body of hte message");
startActivity(Intent.createChooser(intent, ""));

Answer 8

This trick work for ALL version (API 3+), as well as text/plain or text/html (by sonida) :

Intent intent = new Intent(android.content.Intent.ACTION_SEND);
intent.setType("text/html");
// intent.setType("text/plain");
final PackageManager pm = getPackageManager();
final List<ResolveInfo> matches = pm.queryIntentActivities(intent, 0);
ResolveInfo best = null;
for (final ResolveInfo info : matches) {
    if (info.activityInfo.packageName.endsWith(".gm") || info.activityInfo.name.toLowerCase().contains("gmail")) {
        best = info;
        break;
    }
}
if (best != null) {
    intent.setClassName(best.activityInfo.packageName, best.activityInfo.name);
}
intent.putExtra(android.content.Intent.EXTRA_SUBJECT, "YOUR SUBJECT");
intent.putExtra(android.content.Intent.EXTRA_TEXT, Html.fromHtml("YOUR EXTRAS"));

startActivity(intent);

Answer 9

It works.

Intent intent = new Intent(Intent.ACTION_SEND);

String[] strTo = { getString(R.string.mailto) };

intent.putExtra(Intent.EXTRA_EMAIL, strTo);
intent.putExtra(Intent.EXTRA_SUBJECT, getString(R.string.mail_subject));
intent.putExtra(Intent.EXTRA_TEXT, getString(R.string.mail_body));

Uri attachments = Uri.parse(image_path);
intent.putExtra(Intent.EXTRA_STREAM, attachments);

intent.setType("message/rfc822");

intent.setPackage("com.google.android.gm");

startActivity(intent);

Answer 10

The best way to do it, is by using the generic way/method:

Intent intent = new Intent(Intent.ACTION_SEND);
intent.setType("plain/text");
intent.putExtra(Intent.EXTRA_SUBJECT, "Email Subject goes here");
intent.putExtra(Intent.EXTRA_TEXT, "Your Message goes here");
startActivity(Intent.createChooser(intent, ""));

This will give the users a choice where they can pick GMail (if installed) or any other email supporting app they have.

Answer 11

Please check the following code it'll open default mail composer automatically.

try {
        Intent intent = new Intent(Intent.ACTION_MAIN);
        intent.addCategory(Intent.CATEGORY_APP_EMAIL);
        context.startActivity(intent);
} catch (android.content.ActivityNotFoundException anfe) {
        handleException();
}

Answer 12

startActivity(new Intent(Intent.ACTION_SENDTO, Uri.parse("mailto:"+mailId)));

Answer 13

Yes its working code perfectly.....

            Intent intent = new Intent(Intent.ACTION_SEND);
            String[] strTo = { "[email protected]" };
            intent.putExtra(Intent.EXTRA_EMAIL, strTo);
            intent.putExtra(Intent.EXTRA_SUBJECT, "Subject");
            intent.putExtra(Intent.EXTRA_TEXT, "Body");
            intent.setType("message/rfc822");
            intent.setPackage("com.google.android.gm");
            startActivity(intent);

Answer 14

Working as for me is just simple like this:

 Intent(Intent.ACTION_SEND).apply{
            setPackage("com.google.android.gm")
            type = "text/plain"
            putExtra(Intent.EXTRA_TEXT, "Go, go share text!")
        }.also{readyIntent->
            startActivity(readyIntent)
        }

Answer 15

This snippet will open a chooser which is supposed to point to Gmail inbox.

val intent = Intent(Intent.ACTION_MAIN)
intent.addCategory(Intent.CATEGORY_APP_EMAIL)
try {
    startActivity(Intent.createChooser(intent, getString(R.string.open_email_app)))
            } catch (e: ActivityNotFoundException) {
    showErrorDialog(R.string.error_activity_is_not_found)
            }

Answer 16

Neither was working for me, as the subject and message were always empty, until I found the official solution here.

fun composeEmail(addresses: Array<String>, subject: String, attachment: Uri) {
    val intent = Intent(Intent.ACTION_SEND).apply {
        type = "*/*"
        putExtra(Intent.EXTRA_EMAIL, addresses)
        putExtra(Intent.EXTRA_SUBJECT, subject)
        putExtra(Intent.EXTRA_STREAM, attachment)
    }
    if (intent.resolveActivity(packageManager) != null) {
        startActivity(intent)
    }
}

Answer 17

This answer is old,but still appears in the Google Search at first position.

Hence,from the android documentation,the better way to do this now is :

public void composeEmail(String[] addresses, String subject, Uri attachment) {
Intent intent = new Intent(Intent.ACTION_SEND);
intent.setType("*/*");
intent.putExtra(Intent.EXTRA_EMAIL, addresses);
intent.putExtra(Intent.EXTRA_SUBJECT, subject);
intent.putExtra(Intent.EXTRA_STREAM, attachment);
if (intent.resolveActivity(getPackageManager()) != null) {
    startActivity(intent);
}

}

Answer 18

final String package = "com.google.android.gm";
// return true if gmail is installed
boolean isGmailInstalled = isAppInstalled(MainActivity.this, package);

Intent intent = new Intent(Intent.ACTION_SEND);
intent.putExtra(Intent.EXTRA_EMAIL, new String[] {"[email protected]"});
if (isGmailInstalled) {
    intent.setType("text/html");
    intent.setPackage(package);
    startActivity(intent);
} else {  // allow user to choose a different app to send email with
    intent.setType("message/rfc822");
    startActivity(Intent.createChooser(intent, "choose an email client"));
}

// Method to check if app is installed
private boolean isAppInstalled(Context context, String packageName) {
    try {
        context.getPackageManager().getApplicationInfo(packageName, 0);
        return true;
    } catch (PackageManager.NameNotFoundException e) {
        return false;
    }
}
