SmsManager<\/code><\/a> class<\/li>\n- By using an
implicit Intent<\/a><\/code><\/li>\n<\/ul>\nThe use of SmsManager<\/code> facilitates the sms sending because it gives us the opportunity to customize this functionality with the manner we want, within our own Activity<\/code>. In parallel, the use of Intents<\/code> implies the use of built-in applications and sms clients that are installed in each Android device. In this example, we are going to implement both ways. More specifically, we are going to send a sms by using SmsManager<\/code> and implicit Intent<\/code> with SENDTO<\/code> action and\/or VIEW<\/code> action.<\/p>\nFor this tutorial, we will use the following tools in a Windows 64-bit platform:<\/p>\n
\n- JDK 1.7<\/li>\n
- Eclipse 4.2 Juno<\/li>\n
- Android SDK 4.4<\/li>\n<\/ol>\n
1. Create a New Android Application Project<\/h2>\n
Open Eclipse IDE and go to File \u2192 New \u2192 Project \u2192 Android Application Project.<\/p>\n
Specify the name of the application, the project and the package in the appropriate fields. Then click Next.<\/p>\n
![\"sendSmsProj1\"](\"http:\/\/examples.javacodegeeks.com\/wp-content\/uploads\/2013\/12\/sendSmsProj1.png\")
<\/a><\/p>\nIn the next window, choose the \u201cCreate Activity\u201d check-option. The new created activity will be the main activity of your project. Then press Next button. <\/p>\n
![\"sendSmsProj2\"](\"http:\/\/examples.javacodegeeks.com\/wp-content\/uploads\/2013\/12\/sendSmsProj2.png\")
<\/a><\/p>\nIn \u201cConfigure Launcher Icon\u201d window you should choose the icon you want to have in your app. We will use the default icon of android, so click Next. <\/p>\n
![\"createProject3!\"](\"http:\/\/examples.javacodegeeks.com\/wp-content\/uploads\/2013\/11\/createProject3.png\")
<\/a><\/p>\nSelect the \u201cBlank Activity\u201d option and press Next. <\/p>\n
![\"createProject4!\"](\"http:\/\/examples.javacodegeeks.com\/wp-content\/uploads\/2013\/11\/createProject4.png\")
<\/a><\/p>\nSpecify a name for the new Activity and a name for the layout description of your app. The .xml file for the layout will automatically be created in the\u00a0res\/layout<\/code>\u00a0folder. Finally, press Finish. <\/p>\n![\"createProject5!\"](\"http:\/\/examples.javacodegeeks.com\/wp-content\/uploads\/2013\/11\/createProject5.png\")
<\/a><\/p>\nNow, you can see the structure of your created project.<\/p>\n
![\"sendSmsStructure\"](\"http:\/\/examples.javacodegeeks.com\/wp-content\/uploads\/2013\/12\/sendSmsStructure.png\")
<\/a><\/p>\n2. Create the layout of the Main Activity<\/h2>\n
We will put two EditTexts<\/code> so that the user can fill in a phone number and a message for a SMS. Also, we are going to add three different Buttons<\/code>, that each one enables a different action and uses a suitable class (smsManager<\/code>, Intent<\/code> with SENDTO<\/code> action, Intent<\/code> with VIEW<\/code> action).<\/p>\nOpen res\/layout\/activity_main.xml<\/code> and go to the respective xml tab. Then paste the following. <\/div> <\/div><\/p>\nactivity_main.xml:<\/u><\/em><\/p>\n\r\n<?xml version=\"1.0\" encoding=\"utf-8\"?>\r\n<LinearLayout xmlns:android=\"http:\/\/schemas.android.com\/apk\/res\/android\"\r\n android:id=\"@+id\/linearLayout1\"\r\n android:layout_width=\"fill_parent\"\r\n android:layout_height=\"fill_parent\"\r\n android:orientation=\"vertical\" >\r\n\r\n <TextView\r\n android:id=\"@+id\/text\"\r\n android:layout_width=\"fill_parent\"\r\n android:layout_height=\"wrap_content\"\r\n android:text=\"Complete the fields to send a sms\"\r\n android:textAppearance=\"?android:attr\/textAppearanceMedium\" \/>\r\n\r\n <EditText\r\n android:id=\"@+id\/phoneNumber\"\r\n android:layout_width=\"fill_parent\"\r\n android:layout_height=\"wrap_content\"\r\n android:ems=\"10\"\r\n android:hint=\"ex: 1234567890\"\r\n android:inputType=\"phone\" \/>\r\n\r\n <EditText\r\n android:id=\"@+id\/smsBody\"\r\n android:layout_width=\"fill_parent\"\r\n android:layout_height=\"80dp\"\r\n android:layout_marginBottom=\"30dp\"\r\n android:hint=\"Write your sms here....\" \/>\r\n\r\n <Button\r\n android:id=\"@+id\/smsManager\"\r\n android:layout_width=\"fill_parent\"\r\n android:layout_height=\"wrap_content\"\r\n android:text=\"Send the sms by SmsManager\" \/>\r\n\r\n <Button\r\n android:id=\"@+id\/smsSIntent\"\r\n android:layout_width=\"fill_parent\"\r\n android:layout_height=\"wrap_content\"\r\n android:text=\"Send the sms by SENDTO\" \/>\r\n\r\n <Button\r\n android:id=\"@+id\/smsVIntent\"\r\n android:layout_width=\"fill_parent\"\r\n android:layout_height=\"wrap_content\"\r\n android:text=\"Send the sms by VIEW\" \/>\r\n\r\n<\/LinearLayout>\r\n<\/pre>\n3. Code the Main Activity<\/h2>\n
SmsManager<\/code> handles SMS operations and getDefault()<\/code> method should be called, in order to get an instance of this object. For the intent with ACTION_SENDTO<\/code> we have to define the data as smsto:<\/code> and the phone number added at the end. Respectively, for the intent with ACTION_VIEW<\/code> we will define the type as vnd.android-dir\/mms-sms<\/code>, so only sms-mms providers will launch. Also, we have to add the phone number and the message as extra fields to that intent.<\/p>\nOpen src\/com.javacodegeeks.android.sendsmstest\/MainActivity.java<\/code> and paste the following.<\/p>\nMainActivity.java:<\/u><\/em><\/p>\n\r\npackage com.javacodegeeks.android.sendsmstest;\r\n\r\nimport android.app.Activity;\r\nimport android.content.Intent;\r\nimport android.net.Uri;\r\nimport android.os.Bundle;\r\nimport android.telephony.SmsManager;\r\nimport android.view.View;\r\nimport android.view.View.OnClickListener;\r\nimport android.widget.Button;\r\nimport android.widget.EditText;\r\nimport android.widget.Toast;\r\n\r\npublic class MainActivity extends Activity {\r\n\r\n\tprivate EditText phoneNumber;\r\n\tprivate EditText smsBody;\r\n\tprivate Button smsManagerBtn;\r\n\tprivate Button smsSendToBtn;\r\n\tprivate Button smsViewBtn;\r\n\r\n\t@Override\r\n\tpublic void onCreate(Bundle savedInstanceState) {\r\n\t\tsuper.onCreate(savedInstanceState);\r\n\t\tsetContentView(R.layout.activity_main);\r\n\r\n\t\tphoneNumber = (EditText) findViewById(R.id.phoneNumber);\r\n\t\tsmsBody = (EditText) findViewById(R.id.smsBody);\r\n\t\tsmsManagerBtn = (Button) findViewById(R.id.smsManager);\r\n\t\tsmsSendToBtn = (Button) findViewById(R.id.smsSIntent);\r\n\t\tsmsViewBtn = (Button) findViewById(R.id.smsVIntent);\r\n\r\n\t\tsmsManagerBtn.setOnClickListener(new OnClickListener() {\r\n\t\t\t public void onClick(View view) {\r\n\t\t\t\t sendSmsByManager();\r\n\t\t\t }\r\n\t\t});\r\n\t\t\r\n\t\tsmsSendToBtn.setOnClickListener(new OnClickListener() {\r\n\t\t\t public void onClick(View view) {\r\n\t\t\t\t sendSmsBySIntent();\r\n\t\t\t }\r\n\t\t});\r\n\t\t\r\n\t\tsmsViewBtn.setOnClickListener(new OnClickListener() {\r\n\t\t\t public void onClick(View view) {\r\n\t\t\t\t sendSmsByVIntent();\r\n\t\t\t }\r\n\t\t});\r\n\t\t\r\n\t}\r\n\t\r\n\tpublic void sendSmsByManager() {\r\n\t\ttry {\r\n\t\t\t\/\/ Get the default instance of the SmsManager\r\n\t\t\tSmsManager smsManager = SmsManager.getDefault();\r\n\t\t\tsmsManager.sendTextMessage(phoneNumber.getText().toString(), \r\n\t\t\t\t\tnull, \r\n\t\t\t\t\tsmsBody.getText().toString(), \r\n\t\t\t\t\tnull, \r\n\t\t\t\t\tnull);\r\n\t\t\tToast.makeText(getApplicationContext(), \"Your sms has successfully sent!\",\r\n\t\t\t\t\tToast.LENGTH_LONG).show();\r\n\t\t} catch (Exception ex) {\r\n\t\t\tToast.makeText(getApplicationContext(),\"Your sms has failed...\",\r\n\t\t\t\t\tToast.LENGTH_LONG).show();\r\n\t\t\tex.printStackTrace();\r\n\t\t}\r\n\t}\r\n\t\r\n\tpublic void sendSmsBySIntent() {\r\n\t\t\/\/ add the phone number in the data\r\n\t\tUri uri = Uri.parse(\"smsto:\" + phoneNumber.getText().toString());\r\n\t\t\r\n\t\tIntent smsSIntent = new Intent(Intent.ACTION_SENDTO, uri);\r\n\t\t\/\/ add the message at the sms_body extra field\r\n\t\tsmsSIntent.putExtra(\"sms_body\", smsBody.getText().toString());\r\n\t\ttry{\r\n\t\t\tstartActivity(smsSIntent);\r\n\t\t} catch (Exception ex) {\r\n\t\t\tToast.makeText(MainActivity.this, \"Your sms has failed...\",\r\n\t\t\t\t\tToast.LENGTH_LONG).show();\r\n\t\t\tex.printStackTrace();\r\n\t\t}\r\n\t}\r\n\t\r\n\tpublic void sendSmsByVIntent() {\r\n\t\t\r\n\t\tIntent smsVIntent = new Intent(Intent.ACTION_VIEW);\r\n\t\t\/\/ prompts only sms-mms clients\r\n\t\tsmsVIntent.setType(\"vnd.android-dir\/mms-sms\");\r\n\t\t\r\n\t\t\/\/ extra fields for number and message respectively\r\n\t\tsmsVIntent.putExtra(\"address\", phoneNumber.getText().toString());\r\n\t\tsmsVIntent.putExtra(\"sms_body\", smsBody.getText().toString());\r\n\t\ttry{\r\n\t\t\tstartActivity(smsVIntent);\r\n\t\t} catch (Exception ex) {\r\n\t\t\tToast.makeText(MainActivity.this, \"Your sms has failed...\",\r\n\t\t\t\t\tToast.LENGTH_LONG).show();\r\n\t\t\tex.printStackTrace();\r\n\t\t}\r\n\r\n\t}\r\n}\r\n<\/pre>\n4. Set the SMS\u00a0Permission<\/h2>\n
We should set SEND_SMS<\/code> as permission in the AndroidManifest.xml<\/code> file, in order to send an SMS via our application. At this point, we should mention that the permission must be defined for smsManager<\/code>, but it is not necessary for the implicit Intents<\/code>.<\/p>\nOpen AndroidManifest.xml<\/code> file and go to the respective xml tab. Then paste the permission android.permission.SEND_SMS<\/code>, as you can see below.<\/p>\nAndroidManifest.xml:<\/u><\/em><\/p>\n\r\n<?xml version=\"1.0\" encoding=\"utf-8\"?>\r\n<manifest xmlns:android=\"http:\/\/schemas.android.com\/apk\/res\/android\"\r\n package=\"com.javacodegeeks.android.sendsmstest\"\r\n android:versionCode=\"1\"\r\n android:versionName=\"1.0\" >\r\n\r\n <uses-sdk\r\n android:minSdkVersion=\"8\"\r\n android:targetSdkVersion=\"19\" \/>\r\n \r\n <uses-permission android:name=\"android.permission.SEND_SMS\" \/>\r\n\r\n <application\r\n android:allowBackup=\"true\"\r\n android:icon=\"@drawable\/ic_launcher\"\r\n android:label=\"@string\/app_name\"\r\n android:theme=\"@style\/AppTheme\" >\r\n <activity\r\n android:name=\"com.javacodegeeks.android.sendsmstest.MainActivity\"\r\n android:label=\"@string\/app_name\" >\r\n <intent-filter>\r\n <action android:name=\"android.intent.action.MAIN\" \/>\r\n\r\n <category android:name=\"android.intent.category.LAUNCHER\" \/>\r\n <\/intent-filter>\r\n <\/activity>\r\n <\/application>\r\n\r\n<\/manifest>\r\n<\/pre>\n5. Run the application<\/h2>\n
To run our application, right click on our project \u2192 Run as \u2192 Android Application. The AVD will appear with the app loaded.<\/p>\n
Fill in a phone number and a message in order to send a sms, as shown in the picture below.<\/p>\n
![\"ADVSmsProj1\"](\"http:\/\/examples.javacodegeeks.com\/wp-content\/uploads\/2013\/12\/ADVSmsProj1.png\")
<\/a><\/p>\nLets press “Send the sms by SmsManager” button. The sms will be sent via smsManager<\/code>, so a Toast<\/code> will appear which certify the success of sms sending. Otherwise, an error message would be appeared.<\/p>\n![\"ADVSmsProj2\"](\"http:\/\/examples.javacodegeeks.com\/wp-content\/uploads\/2013\/12\/ADVSmsProj2.png\")
<\/a><\/p>\nNow press the “Send the sms by SENDTO” button. If more than one applications, that use a SENDTO<\/code> action exist, the user will choose one of the displayed ones. For example, our emulator contains an application that uses an implicit intent with ACTION_SENDTO<\/code>, as shown in the picture. <\/p>\n![\"ADVSmsProj3\"](\"http:\/\/examples.javacodegeeks.com\/wp-content\/uploads\/2013\/12\/ADVSmsProj3.png\")
<\/a> <\/p>\nLets choose the default Android app for sms. As you can see in the picture below, the fields are completed with the elements that the user gave previously.<\/p>\n
