imageSwitcher and memory errors

Tags:

memory

image

I am using very simple code to show gallery of images stored as drawables. All images are less than 200kb in size and 1024x576 pixels resolution.

my code works fine on 4 devices I tested and for the most of my users. But some of them keep getting famous vm budget memory issue.

he is my code:

in 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 the code to show images:

try {
    // this is internal image loaded from drawables
    imageSwitcher.setImageResource(images.get(imageNumber - 1).imageResourceID);

} catch (Exception e) {
    // no image will be shown
}

error happens on some phones (very very small percent of downloads) in try/catch block and with some phones activity cannot even start at all.

I read about recycling bitmaps and memory leaks issues, but my activity is run in sigle-top mode and not recreated on orientation changes, so it is always the same activity. I also do not use bitmaps directly.

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

first type of error:

About the Bitmap error:
You should consider down sampling your bitmap and resize them before creating them in memory. take a look at the following thread Handling Large Bitmaps

The second errors is cause the runtime is unable to create a view hierarchy from the Layout XML. Are you using a custom view in your layout?

Edit: your layout XML looks correct and now that you've posted entire dump, to me the only problem is size of the Bitmap. I still maintain that you will have to down sample the images.

What is the format of your images; a 1024 x 576 JPEG image could be too big when decompressed into Bitmap.

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