This example demonstrates how do I send an email with a file attachment in android.
Step 1 − Create a new project in Android Studio, go to File ⇒ New Project and fill all required details to create a new project.
Step 2 − Add the following code to res/layout/activity_main.xml.
<?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="https://schemas.android.com/apk/res/android" xmlns:tools="https://schemas.android.com/tools" android:layout_width="match_parent" android:layout_height="wrap_content" android:orientation="vertical" android:padding="4dp" tools:context=".MainActivity"> <EditText android:id="@+id/etTo" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_margin="5dp" android:hint="Receiver's Email Address!" android:inputType="textEmailAddress" android:singleLine="true" /> <EditText android:id="@+id/etSubject" android:layout_width="match_parent" android:layout_height="wrap_content" android:layout_margin="5dp" android:hint="Enter Subject" android:singleLine="true" /> <EditText android:id="@+id/etMessage" android:layout_width="match_parent" android:layout_height="200dp" android:layout_margin="5dp" android:gravity="top|start" android:hint="Compose Email" android:inputType="textMultiLine" /> <RelativeLayout android:layout_width="match_parent" android:layout_height="wrap_content"> <Button android:id="@+id/btSend" android:layout_width="80dp" android:layout_height="50dp" android:layout_margin="5dp" android:text="Send" /> <Button android:id="@+id/btAttachment" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_alignParentEnd="true" android:text="attachment" /> </RelativeLayout> <TextView android:id="@+id/tvAttachment" android:layout_width="match_parent" android:layout_height="wrap_content" android:drawableStart="@drawable/ic_attach" android:visibility="gone" /> </LinearLayout>
Step 3 − Add the following code to src/MainActivity.java
import android.app.Activity;
import android.content.Intent;
import android.net.Uri;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;
import android.widget.TextView;
import android.widget.Toast;
public class MainActivity extends Activity {
EditText etEmail;
EditText etSubject;
EditText etMessage;
Button Send;
Button attachment;
TextView tvAttachment;
String email;
String subject;
String message;
Uri URI = null;
private static final int PICK_FROM_GALLERY = 101;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
etEmail = findViewById(R.id.etTo);
etSubject = findViewById(R.id.etSubject);
etMessage = findViewById(R.id.etMessage);
attachment = findViewById(R.id.btAttachment);
tvAttachment = findViewById(R.id.tvAttachment);
Send = findViewById(R.id.btSend);
Send.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
sendEmail();
}
});
//attachment button listener
attachment.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
openFolder();
}
});
}
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == PICK_FROM_GALLERY && resultCode == RESULT_OK) {
URI = data.getData();
tvAttachment.setText(URI.getLastPathSegment());
tvAttachment.setVisibility(View.VISIBLE);
}
}
public void sendEmail() {
try {
email = etEmail.getText().toString();
subject = etSubject.getText().toString();
message = etMessage.getText().toString();
final Intent emailIntent = new Intent(android.content.Intent.ACTION_SEND);
emailIntent.setType("plain/text");
emailIntent.putExtra(android.content.Intent.EXTRA_EMAIL, new String[]{email});
emailIntent.putExtra(android.content.Intent.EXTRA_SUBJECT, subject);
if (URI != null) {
emailIntent.putExtra(Intent.EXTRA_STREAM, URI);
}
emailIntent.putExtra(android.content.Intent.EXTRA_TEXT, message);
this.startActivity(Intent.createChooser(emailIntent, "Sending email..."));
} catch (Throwable t) {
Toast.makeText(this, "Request failed try again: "+ t.toString(), Toast.LENGTH_LONG).show();
}
}
public void openFolder() {
Intent intent = new Intent();
intent.setType("image/*");
intent.setAction(Intent.ACTION_GET_CONTENT);
intent.putExtra("return-data", true);
startActivityForResult(Intent.createChooser(intent, "Complete action using"), PICK_FROM_GALLERY);
}
}Step 4 − Add the following code to androidManifest.xml
<?xml version="1.0" encoding="utf-8"?> <manifest xmlns:android="https://schemas.android.com/apk/res/android" package="app.com.sample"> <uses-permission android:name="android.permission.INTERNET" /> <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" /> <uses-permission android:name="android.permission.READ_INTERNAL_STORAGE" /> <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" /> <application android:allowBackup="true" android:icon="@mipmap/ic_launcher" android:label="@string/app_name" android:roundIcon="@mipmap/ic_launcher_round" android:supportsRtl="true" android:theme="@style/AppTheme"> <activity android:name=".MainActivity"> <intent-filter> <action android:name="android.intent.action.MAIN" /> <category android:name="android.intent.category.LAUNCHER" /> </intent-filter> </activity> </application> </manifest>
Let's try to run your application. I assume you have connected your actual Android Mobile device with your computer. To run the app from android studio, open one of your project's activity files and click Runicon from the toolbar. Select your mobile device as an option and then check your mobile device which will display your default screen −
