Saving Image Clicked From Camera Or Loaded From Gallery In Database And Retrieving It

I am trying to save the image in imageview alongwith the other fields that user inputs. I wish to store the image in database and it will be retrieved on other page when the data i

Solution 1:

Do this to get the bitmap from the imageview:

Bitmap myBitmap= ((BitmapDrawable)image.getDrawable()).getBitmap();

then you need to convert the bitmap to a byte array:

ByteArrayOutputStreamstream=newByteArrayOutputStream();
myBitmap.compress(Bitmap.CompressFormat.PNG, 100, stream);
byte[] byteArray = stream.toByteArray();

then you can store it as a blob in the DB

EDIT:

to retrieve the bimap you get the byte array from the db and convert it back to a bitmap

Cursorc= db.raw......
    byte[] byteArray = c.getBlob(0);

    Bitmapbm= BitmapFactory.decodeByteArray(byteArray, 0, byteArray.length);

Now you can just set the ImageView bitmap to the retrieved bitmap.

Solution 2:

Instead of storing and retrieving from DB, since your usage is for one time, you should store the image in a public static variable which you can access across whole project.

publicstatic Uri publicSelectedImage; // Write this in NewPat at class level. 

in your onActivityResult() assign value to this variable as following

UriselectedImage= data.getData();
publicSelectedImage = selectedImage;         // write this line. 

Now from any other activity you can access this variable as following way,

UripublicImage= NewPat.publicSelectedImage;
