1. Launching to Activities
To start Activities, we must make two steps as follow:

1<activity
2 android:name=".SecondActivity"
3 android:label="@string/title_activity_second" >
4 <intent-filter>
5 <action android:name="android.intent.action.MAIN" />
6
7 <category android:name="android.intent.category.LAUNCHER" />
8 </intent-filter>
9 </activity>
2 android:name=".SecondActivity"
3 android:label="@string/title_activity_second" >
4 <intent-filter>
5 <action android:name="android.intent.action.MAIN" />
6
7 <category android:name="android.intent.category.LAUNCHER" />
8 </intent-filter>
9 </activity>
Step 2: Create Intent to call the Activity.
1Intent secondActivity = new Intent(this, SecondActivity.class);
2 startActivity(secondActivity)
;2 startActivity(secondActivity)
2.2. Start Service
To start Services, we must make two steps as follow:
Step 1: Declare Service in Manifest.
1<service android:name="MyService" >
2 </service>
2 </service>
Step 2: Create Intent to call the Service.
1Intent myServiceIntent = new Intent(this, MyService.class);
2 startService(myServiceIntent);
2 startService(myServiceIntent);
2.3. Send BroadcastReceiver
To start BroadcastReceiver, we must make two steps as follow:
Step 1: Declare BroadcastReceiver in Manifest.
1<receiver android:name="MyBroadcastReceiver" >
2 <intent-filter>
3 <action android:name="com.example.intenttutorial.myrecevier" />
4 </intent-filter>
5 </receiver>
Step 2: Create Intent to send the BroadcastReceiver.2 <intent-filter>
3 <action android:name="com.example.intenttutorial.myrecevier" />
4 </intent-filter>
5 </receiver>
1Intent broadcastIntent = new Intent(broadcastFilter);
2 broadcastIntent.putExtra("9Android.net","MyBroadcastReciver is called!");
3 sendBroadcast(broadcastIntent);
2 broadcastIntent.putExtra("9Android.net","MyBroadcastReciver is called!");
3 sendBroadcast(broadcastIntent);
