Pass image through intent using URI to another activity

Question

I am a beginner in programming. I am trying to create Meme generator app. I have got to a point where I display an array of images in a GridView, user can click on one image and it will take them to a new activity where user can enter top and bottom text.

I would appreciate your help with below based on the code I have.

• A) I am trying to convert a Relative Layout (two TextViews and one ImageView) in a bitmap. Is the code correct?
• - B) I want to send bitmap created from Relative Layout to FullImage.java activity when user clicks on Create button. Is the code correct you think?
• - C) When Create button is clicked by the user, currently I get "Failed Binder Transaction". I think its because I am passing an image. I tried to understand and use how to pass URI but was not
  successful. I tried to find snippet on SO and other blogs but was not successful. Is it possible for you to give me detail code? (As a beginner, Ill be thankful!)

Answer 1

In your FullImageActivity, do this to retrieve the bitmap

   Intent intent = getIntent();
   Bitmap bitmap = (Bitmap) intent.getParcelableExtra("pic"); 

This is because the bitmap class in android implements parcelable. http://developer.android.com/reference/android/graphics/Bitmap.html
