Android start app from email

How to open an installed app from an email URL in Android? [duplicate]

I want to open my app from an email URL, basically like the example shown below for Twitter.com.

Email with link:

Selection to open app or browser:

After you click on the app choice, the Twitter app opens:

I tried the following code, but it is not working:

If anyone has a proper answer, please write some examples here.

The following code worked for me:

With the email link set as http://www.my.app.com/launch .

Ex: Your url will be something like https://roadies.com and you have the intent filter in manifest as below

For me, none of the answers posted here worked. I tried tens of different syntaxes without any success. I was getting a parsing error while building the app via Cordova.

I finally encountered this answered which led me on the right track.

So I created a hook in the PROJECT_ROOT/hooks/after_prepare/ folder called 010_add_intent_filters.sh . Here is the content of this hook :

This finally worked. No modification to config.xml is required if you take the hook path. I hope this helps someone in need.

PS: I am convinced Cordova is a great technology, but I have rarely seen such a badly documented library. How painful it is to work with it is just unbelievable.

How to send emails from my Android application?

I am developing an application in Android. I don’t know how to send an email from the application?

24 Answers 24

The best (and easiest) way is to use an Intent :

Otherwise you’ll have to write your own client.

Use .setType(«message/rfc822») or the chooser will show you all of the (many) applications that support the send intent.

I’ve been using this since long time ago and it seems good, no non-email apps showing up. Just another way to send a send email intent:

I was using something along the lines of the currently accepted answer in order to send emails with an attached binary error log file. GMail and K-9 send it just fine and it also arrives fine on my mail server. The only problem was my mail client of choice Thunderbird which had troubles with opening / saving the attached log file. In fact it simply didn’t save the file at all without complaining.

I took a look at one of these mail’s source codes and noticed that the log file attachment had (understandably) the mime type message/rfc822 . Of course that attachment is not an attached email. But Thunderbird cannot cope with that tiny error gracefully. So that was kind of a bummer.

After a bit of research and experimenting I came up with the following solution:

It can be used as follows:

As you can see, the createEmailOnlyChooserIntent method can be easily fed with the correct intent and the correct mime type.

It then goes through the list of available activities that respond to an ACTION_SENDTO mailto protocol intent (which are email apps only) and constructs a chooser based on that list of activities and the original ACTION_SEND intent with the correct mime type.

Another advantage is that Skype is not listed anymore (which happens to respond to the rfc822 mime type).

How to start an application using Android ADB tools

How do I send an intent using Android’s ADB tools?

14 Answers 14

Or you can use this directly:

You can also specify actions to be filter by your intent-filters:

/.bash_profile to be much faster function androidrun() < ant clean debug adb shell am start -n $1/$1.MainActivity >and its usage androidrun com.example.test

It’s possible to run an application specifying the package name only using the monkey tool by follow this pattern:

The command is used to run the app using the monkey tool which generates random input for the application. The last part of the command is an integer which specifies the number of generated random input for the app. In this case the number is 1, which in fact is used to launch the app (icon click).

Or, you could use this:

/android-sdk-linux/build-tools/20.0.0/aapt dump badging yourapp.apk , which will list the following entry: launchable-activity: name=’com.company.android.package.YourLaunchableActivity’

Linux and Mac users can also create a script to run an APK file with something like the following:

Create a file named «adb-run.sh» with these three lines:

Then «chmod +x adb-run.sh» to make it executable.

Now you can simply:

The benefit here is that you don’t need to know the package name or launchable activity name. Similarly, you can create «adb-uninstall.sh myapp.apk»

Note: This requires that you have Android Asset Packaging Tool ( aapt ) in your path. You can find it under the new build tools folder in the SDK.

Step 1: First get all the package names of the apps installed in your device, by using:

Step 2: You will get all the package names. Copy the one you want to start using ADB.

Step 3: Add your desired package name in the below command.

to start the Es explorer.

Also, I want to mention one more thing.

When you start an application from adb shell am , it automatically adds FLAG_ACTIVITY_NEW_TASK flag which makes behavior change. See the code.

For example, if you launch a Play Store activity from adb shell am , pressing the ‘Back‘ button (hardware back button) wouldn’t take you your app. Instead, it would take you previous Play Store activity if there was some (if there was not a Play store task, then it would take you to your app). FLAG_ACTIVITY_NEW_TASK documentation says:

if a task is already running for the activity you are now starting, then a new activity will not be started; instead, the current task will simply be brought to the front of the screen with the state it was last in

This caused me to spend a few hours to find out what went wrong.

So, keep in mind that adb shell am add FLAG_ACTIVITY_NEW_TASK flag.

Sending Email in Android using JavaMail API without using the default/built-in app

I am trying to create a mail sending application in Android.

This will launch the built-in Android application; I’m trying to send the mail on button click directly without using this application.

Send e-mail in Android using the JavaMail API using Gmail authentication.

Steps to create a sample Project:

MailSenderActivity.java:

GMailSender.java:

JSSEProvider.java:

ADD 3 jars found in the following link to your Android Project

And don’t forget to add this line in your manifest:

Just click below link to change account access for less secure apps https://www.google.com/settings/security/lesssecureapps

Run the project and check your recipient mail account for the mail. Cheers!

P.S. And don’t forget that you cannot do network operation from any Activity in android. Hence it is recommended to use AsyncTask or IntentService to avoid network on main thread exception.

Thank you for your valuable information. Code is working fine. I am able to add attachment also by adding following code.

Could not connect to SMTP host: smtp.gmail.com, port: 465

Add this line in your manifest:

You can use JavaMail API to handle your email tasks. JavaMail API is available in JavaEE package and its jar is available for download. Sadly it cannot be used directly in an Android application since it uses AWT components which are completely incompatible in Android.

You can find the Android port for JavaMail at the following location: http://code.google.com/p/javamail-android/

Add the jars to your application and use the SMTP method

100% working code with demo You can also send multiple emails using this answer.

Download Project HERE

Step 1: Download mail, activation, additional jar files and add in your project libs folder in android studio. I added a screenshot see below Download link

Login with gmail (using your from mail) and TURN ON toggle button LINK

Most of the people forget about this step i hope you will not.

Step 2 : After completing this process. Copy and past this classes into your project.

GMail.java

SendMailTask.java

Step 3 : Now you can change this class according to your needs also you can send multiple mail using this class. i provide xml and java file both.

activity_main.xml

SendMailActivity.java

Note Dont forget to add internet permission in your AndroidManifest.xml file

Hope it work if it not then just comment down below.

In order to help those getting a Network On Main Thread Exception with an SDK Target >9. This is using droopie’s code above but will work similarly for any.

You can use AsyncTask as below

Using SMTP is one way to go, and the others have already pointed out ways how to do it. Just note that while doing this, you completely circumvent the built in mail app, and you will have to provide the address of the SMTP server, the user name and password for that server, either statically in your code, or query it from the user.

Another way would involve a simple server side script, like php, that takes some URL parameters and uses them to send a mail. This way, you only need to make an HTTP request from the device (easily possible with the built in libraries) and don’t need to store the SMTP login data on the device. This is one more indirection compared to direct SMTP usage, but because it’s so very easy to make HTTP request and send mails from PHP, it might even be simpler than the direct way.

Mail Application

If the mail shall be send from the users default mail account that he already registered with the phone, you’d have to take some other approach. If you have enough time and experience, you might want to check the source code of the Android Email application to see if it offers some entry point to send a mail without user interaction (I don’t know, but maybe there is one).

Maybe you even find a way to query the users account details (so you can use them for SMTP), though I highly doubt that this is possible, because it would be a huge security risk and Android is built rather securely.

• Now go to dependencies and from the right click on the green + sign and then click on file dependencies.

file dependencies

• Now go to libs folder and add all the three .jar files (you can see in the image)

adding jar android studio

• Now click on ok, ok and you have added the apis to your project.
• Now come to activity_main.xml and create the following layout.

android email app

• Use the following code for creating the above layout.

• For this android email app we will use gmail to send emails. So create a new java class named Config.java and write the following code.

• You have to write your gmail username and password.
• Now create a new class SendMail.java. It will send our email. Write the following code in this class.

• Now come to MainActivity.java and write the following code.

• Finally add internet permission to manifest.

Allow Access Less Secured App

I also gave permission. Never again

this security setting works for me thanks

Hello sir, I had also the same problem. I put my exact gmail account and password but I don’t still get any mails. Even though it tells me that the mail was sent. Please help me. Thank you

The application works properly, however gmail has a security setting which needs to be addressed.
You need to go to your security settings and turn on “Allow less secure apps:”.

Hi , thanks for this tutorial , but i have question : can i make this app accept any types of emails ( yahoo , hotmail , gmail , ….. ) ?

Same question! I already tried several different ways but I wasn’t successful.
I’m trying to send an Email with the Email address the user’s typing in a text field.
Any help is appreciated!

thanks for the code. but i am getting error in MainActivity.java file in Error:(3, 30) error: cannot find symbol class AppCompatActivity and Error:(31, 36) error: cannot find symbol method findViewById(int). i did all the dependencies in the exact way. waiting for your reply.

Actually this is the problem with your sdk, update your android studio and sdk. Or you can use Activity or ActionbarActivity instead of AppCompatActivity

yeah!! it is working now. can i have your email, so that i can contact you directly?.

• 

Visit about page 😉

Thank u for your code!! Could you also show how to receive messages using JavaMail API, please? I tried to rework your code, but it wasn’t successful:(

Hello , this message is being translated by Google Translate because I do not speak English, I hope you understand .

//Setting sender address
mm.setFrom(new InternetAddress(Config.EMAIL));
//Adding receiver
mm.addRecipient(Message.RecipientType.TO, new InternetAddress(email));

//Setting sender address
mm.setFrom(new InternetAddress(>>email<>Config.EMAIL Reply

not working on my android device even no error in coding……

I implement the same as you have done!
but no message is received in the target email address.
I changed the config file also.
here is the logcat :
01-17 22:19:41.473 12231-12231/polimi.aap.yas.personalhealthrecord E/ViewRootImpl: sendUserActionEvent() mView == null

it says sign in attempt was blocked in my mail

You need to enable POP go to your gmail and from settings enable POP or IMAP

Thank you . Your code and this reply helped me a lot to put the application working. It turns out htat the POP/IMAP was turn off on gmail setting.

thanks for the tut..but when i have my mail and pass stored in config.java .what i want is when user uses my app and wants to send a mail to me, im not getting the mail to my mail ,instead it shows like u got a mail from sv53@gmail.com(this is in config file) to the mail which i entered in receipient field .
when a user send a mail using his mail id, i need to get mail to my sv53 mail id, but how to?

If you are having problems disable you anti-virus and check it again…

Also had to allow less secure app in google.

It works . Thanks man, God Bless You 🙂

It is showing me Message sent in toast but when i check gmail account no mail is received..

Cool tut, I wish I understood Android Studio better but I am just now teaching myself and could use help on a couple projects. I can only imagine how busy you must be, but if you would/could help me just a bit, I sure would appreciate it! If you are interested, please contact me via admin@mohtech.ca

Thank you in advance!

I get the same error. Can anyone help?
Error: java.lang.NoClassDefFoundError: com.sun.mail.util.MailLogger

You should check the gradle file
(App). If you have written duplicate about mail, it would have shown error message like you.
For example, in your gradle file,
If there are more than a line,
compile javax.javamail.5-
dependencies <
compile fileTree(dir: ‘libs’, include: [‘*.jar’])
-> this is two lines about javamail.

So delete one of them. 🙂 i solved the problem in this way
