Instead of using setClassName use setComponent, as below

Intent intentDeviceTest = new Intent("android.intent.action.MAIN");  
intentDeviceTest.setComponent(new ComponentName("com.intent.service",
                                 "com.intent.service.InentServiceDemoActivity"));
startActivity(intentDeviceTest);

i've tried this code now and it works , it opens the AddAccount Activity : 

Intent intent = new Intent(Settings.ACTION_ADD_ACCOUNT);
        startActivity(intent);

All the answer are correct. You should however NEVER target an application by package name UNLESS it is your application. This will cause problems with future releases if you follow this pattern.

Try...

Intent intent = new Intent(DevicePolicyManager.ACTION_ADD_DEVICE_ADMIN);
startActivity(intent);

From the docs...

DevicePolicyManager.ACTION_ADD_DEVICE_ADMIN

you can read this code 

public class CurrentActivity extends Activity {
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {       
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        Intent intent=new Intent(this,TargetActivityName.class);       
        this.startActivity(intent);

    }
}

Set DeviceAdminAdd activity property exported=true in manifest file. and call as follows:

Intent intent = new Intent(com.android.settings.this, com.android.settings.DeviceAdminAdd.class);
startActivity(intent);

Try this instead(note the 1st line is different):

Intent intent = new Intent(Intent.ACTION_MAIN);
intent.setClassName("com.android.settings", "com.android.settings.DeviceAdminAdd");
startActivity(intent);

If it doesn't work for some reason another (better) option is to use the PackageManager to get an Intent for the package:

PackageManager pm = getPackageManager();
Intent intent = pm.getLaunchIntentForPackage("com.android.settings");
startActivity(intent);

Please try this, 

Intent LaunchIntent = getPackageManager().getLaunchIntentForPackage("com.package.address");
startActivity( LaunchIntent );
