android aidl import

aidl, android, import

Solution

Using `android.content.Context` isn't going to work since it doesn't implement `android.os.Parcelable`.

However - ff you have a class (`MyExampleParcelable` for instance) that you want to transfer in an AIDL interface (& that actually implements `Parcelable`) you create an `.aidl` file, `MyExampleParcelable.aidl` in which you write:

package the.package.where.the.class.is;

parcelable MyExampleParcelable;

Now, unless you desperately want to talk across processes you should consider local services. Edit(slightly more helpful):

Is this a local service (i.e. it will only be used inside your own application & process)? In these cases it's usually just better to implement a binder and return that directly.

public class SomeService extends Service {
    ....
    ....
    public class SomeServiceBinder extends Binder {
        public SomeService getSomeService() {
            return SomeService.this;
        }
    }

    private final IBinder mBinder = new SomeServiceBinder();

    @Override
    public IBinder onBind(Intent intent) {
        return mBinder;
    }

    public void printToast(Context context, String text) {
        // Why are you even passing Context here? A Service can create Toasts by it self.
        ....
        ....
    }
    // And all other methods you want the caller to be able to invoke on
    // your service.
}

Basically, when the `Activity` has bound to your service it will simply cast the resulting `IBinder` to `SomeService.SomeServiceBinder`, call `SomeService.SomeServiceBinder#getSomeService()` - and bang, access to the running `Service` instance + you can call stuff in its API.

Problem

I'm trying to import android.content.Context to AIDL file but eclipse doesn't recognize it.. here's my code: ``` package nsip.net; import android.content.Context; // error couldn't find import for class ... interface IMyContactsService{ void printToast(Context context, String text); } ``` Can anyone help me?
