Open new Activity from Xamarin Custom Renderer

Question

This is my first Custom Renderer project and just getting hold of xamarin. I have a Camera Custom Renderer, and want to pass the image preview (through the file path) to another activity for extra functions, in Android. Using the classic:

            Intent intent = new Intent(this, typeof(ResultPage));
        StartActivity(intent);

It throws to errors: -The first one in "this", says that "error CS1503 argument 1: 'CustomRenderer.Droid.CameraPageRenderer' canto be converted to 'Android.Content.Context'" -Second, is in "StartActivity" that says "Error CS0103 The name 'StartActivity' doesn't exist in the actual context 'CustomRenderer.Android'"

Here's is the method where it should go:

        async void TakePhotoButtonTapped(object sender, EventArgs e)
    {
        camera.StopPreview();

        var image = textureView.Bitmap;

        try
        {
            var absolutePath = Android.OS.Environment.GetExternalStoragePublicDirectory(Android.OS.Environment.DirectoryDcim).AbsolutePath;
            var folderPath = absolutePath + "/Images";
            var filePath = System.IO.Path.Combine(folderPath, string.Format("image_{0}.jpg", Guid.NewGuid()));

            var fileStream = new FileStream(filePath, FileMode.Create);
            await image.CompressAsync(Bitmap.CompressFormat.Jpeg, 50, fileStream);
            fileStream.Close();

            image.Recycle();

            var intent = new Android.Content.Intent(Android.Content.Intent.ActionMediaScannerScanFile);
            var file = new Java.IO.File(filePath);
            var uri = Android.Net.Uri.FromFile(file);
            intent.SetData(uri);
            MainActivity.Instance.SendBroadcast(intent);

            CameraPageRenderer cameraPageRenderer = this;
            Intent intent = new Intent(this, typeof(ResultPage));
            StartActivity(intent);

        }
        catch (Exception ex)
        {
            System.Diagnostics.Debug.WriteLine(@"               ", ex.Message);
        }

A CustomRenderer is not an Android Context. You need to retrieve the current Android Context and use it:

var context = this.Context;
Intent intent = new Intent(context, typeof(ResultPage));
context.StartActivity(intent);

Remember that your custom renderer needs to implement the parameterized constructor that accepts a Context as it's parameter in order for this to work:

public MyCustomRenderer(Context context) : base(context) { }
