How to use a intent in android?

Question

I have a sony smart watch and i'm trying to invoke a vibration intent by using the following:

Intent intentImplicit = new Intent(Control.Intents.CONTROL_VIBRATE_INTENT);
startActivity(intentImplicit);

it says startActivity its not declared in the control extension. How can I fix this? I found this online "You can get a Context object from the Constructor for the Control and save it to a member variable then just call context.startActivity()." but i'm unsure on how to do this

Answer 1

What is the purpose of trying to send that Intent? If you are just trying to activate the Vibration, there is already a method built into the utilities class to do this. Take a look at the ControlExtension.startVibrator() method in the SmartExtensionUtils project.

Answer 2

The Sony SDK documentation says you should use sendBroadcast()

See: http://developer.sonymobile.com/reference/sony-addon-sdk/com/sonyericsson/extras/liveware/aef/control/Control.Intents#CONTROL_VIBRATE_INTENT

So this should work:

context.sendBroadcast(intentImplicit, Registration.HOSTAPP_PERMISSION);

If you used a sample application from Sony as base, the context is already saved as a field of your class. If not, you can get a reference in the constructor of the Extension and save it to a field like this:

public class TestExtension extends ControlExtension 
{
    private Context context;

    TestExtension(final String hostAppPackageName, final Context context, Handler handler) 
    {
        super(context, hostAppPackageName);
        this.context = context;
    }
}
