Changing ImageView content causes OutOfMemoryError

android, android-widget

Solution

Seems like before loading a new Bitmap I had to recycle the Bitmap displayed by the ImageView, now it is working without a problem. Hope this helps someone else, just call the folowing method before setting the new ImageView's content.

`((BitmapDrawable)imageView.getDrawable()).getBitmap().recycle();`

so the code now looks like this:

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data){
    super.onActivityResult(requestCode, resultCode, data);
    switch(requestCode){
        case INTENT_REQUEST_SELECT_IMAGE:
            if(resultCode==Activity.RESULT_OK){
                Uri selectedImageUri = data.getData();
                Log.i(TAG,"selectedImageUri.getPath()"+selectedImageUri.getPath() );
                ImageView imageView = (ImageView) this.findViewById(R.id.ImageView_of_text);
                ((BitmapDrawable)imageView.getDrawable()).getBitmap().recycle();
                imageView.setImageURI(selectedImageUri);
                imageView.invalidate();

            }else{
                //TODO define what to do in case the user canceled OCR or any other event
            }
            break;
        default:
            break;
    }
}

Please note the call to recycle on the Bitmap of the ImageView.

Problem

I have a very simple application with one ImageView and a Button. The first Drawable resource loaded by my ImageView is specified with the "android:src" tag in the XML Layout, however at runtime i want to change the picture displayed by it. To do so i start an Activity for result to pick an image from the sd card (intent sent to MediaStore.Images.Media.EXTERNAL_CONTENT_URI). However when the picture is selected, i try to update the ImageView with the chosen Picture's URI but i get the message "java.lang.OutOfMemoryError: bitmap size exceeds VM budget" I'am trying to load pictures taken with the camera (pics size are around 1.1M) of my HTC-Hero but no success, seems to work only with pictures that are less than 500KB.However i need to load pictures taken with the camera. How can i solve this? what am I doing wrong. Seem to me that the code is very simple and should work. ``` public void onClick(View v){ Intent selectImageIntent=new Intent(Intent.ACTION_PICK , android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI); startActivityForResult(selectImageIntent,1); } @Override protected void onActivityResult(int requestCode, int resultCode, Intent data){ super.onActivityResult(requestCode, resultCode, data); if(resultCode==Activity.RESULT_OK){ Uri selectedImageUri = data.getData(); Log.i(TAG,"chosen image: "+selectedImageUri.toString()); ImageView imageView = (ImageView) this.findViewById(R.id.ImageView01); imageView.setImageURI(selectedImageUri);//here I get the OutOfMemoryError imageView.invalidate(); }else{ //canceled } } ``` p.s. that is the only thing the App should do, I'm not creating other objects so I will like to point out that I am not using heap space for other stuff besides displaying the image.
