ImageSwitcher and memory errors

Question

I use very simple code to show a gallery of images stored as drawings. All images are less than 200kb in size and have a resolution of 1024x576 pixels.

my code works fine on the 4 devices I tested, and for most of my users. But some of them continue to get a known issue with vm budget memory.

he is my code:

in the onCreate () method of my activity:

// set Factory for Image Switcher imageSwitcher = (ImageSwitcher) findViewById(R.id.ImageSwitcher); imageSwitcher.setFactory(new MyImageSwitcherFactory()); 

Factory class:

 private class MyImageSwitcherFactory implements ViewFactory { public View makeView() { ImageView imageView = new ImageView(Main.this); imageView.setScaleType(ImageView.ScaleType.CENTER_CROP); imageView.setLayoutParams(new ImageSwitcher.LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.FILL_PARENT)); return imageView; } } 

and code for displaying images:

 try { // this is internal image loaded from drawables imageSwitcher.setImageResource(images.get(imageNumber - 1).imageResourceID); } catch (Exception e) { // no image will be shown } 

The error on some phones (a very small percentage of downloads) in the try / catch block and with some phone actions cannot start at all.

I read about recycling bitmaps and memory leaks, but my activity runs in sigle-top mode and does not recreate when orientation changes, so this is always the same action. I also do not use bitmap images directly.

Can I improve my code to get rid of this error?

Answer 1

Bitmap Error:
You should consider sampling your bitmap and resizing it before creating it in memory. take a look at the next stream Processing large raster images

The second mistake is that the runtime cannot create a hierarchy of views from an XML layout. Do you use a custom view in your layout?

Edit : your XML format looks correct, and now that you have placed the entire dump, the only problem for me is the size of the bitmap. I still claim that you will have to dump sample images.

What is the format of your images; An image with a resolution of 1024 x 576 may be too large when decompressed in Bitmap .

See if any of these discussions provide any pointers: 1 , 2 , 3 .
