android – Put a big image in an ImageView not working

Posted by: admin June 15, 2020 Leave a comment


I think there is a problem with my ImageView.
i created a gallery, where I can touch an image and put it in my ImageView below:

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

<Gallery android:layout_height="wrap_content" 
    android:layout_width="fill_parent" />

<ImageView android:layout_below="@+id/gallery"

This is perfectly working with small image, but not with big image (3264 * 1952). When I touch it (so, trying to put it in the ImageView), I have an error and my appplication crash.
Here is my java code to display the image:

        public void onCreate(Bundle savedInstanceState) {


            File images; // Trouver le bon endroit de stockage
            if (Environment.MEDIA_MOUNTED.equals(Environment.getExternalStorageState()))
                images = new File("/sdcard/MyPerformance/Photo");
                images = this.getFilesDir();

            File[] imagelist = images.listFiles(new FilenameFilter(){   
                public boolean accept(File dir, String name)   
                    return ((name.endsWith(".jpg"))||(name.endsWith(".png")));

            mFiles = new String[imagelist.length];
            for(int i = 0 ; i< imagelist.length; i++)   
                mFiles[i] = imagelist[i].getAbsolutePath();   
            mUrls = new Uri[mFiles.length];
            for(int i = 0; i < mFiles.length; i++)   
                mUrls[i] = Uri.parse(mFiles[i]);      

            imgView = (ImageView)findViewById(R.id.laphoto);
            if(mFiles.length != 0)

            gallery = (Gallery) findViewById(R.id.gallery);
            gallery.setAdapter(new ImageAdapter(this));

            gallery.setOnItemClickListener(new OnItemClickListener() {
                public void onItemClick(AdapterView<?> parent, View v, int position, long id) {

Either the problem comes from the setImageURI (but I don’t think this is the cause, since it’s work with small image) or because of the size of the picture.

What solution can you give me to resolve this problem?
You have my thanks.

How to&Answers:

Your image is probably too big for Android and it goes out of memory. Apps might have as low as 16Mb of usable memory. Your image takes 3264 * 1952 * 4 = ~25.5Mb (widthheightargb). So might be best to resize the images into smaller size.

See: http://android-developers.blogspot.co.uk/2009/01/avoiding-memory-leaks.html
Then: Strange out of memory issue while loading an image to a Bitmap object
Finally: VM running out of memory while getting images from the cache


Here’s a bitmap[ util class to assist you with the handling of the large bitmaps.

import android.graphics.Bitmap;
import android.graphics.BitmapFactory;

public class BitmapUtils {

    public static int calculateInSampleSize(
            BitmapFactory.Options options, int reqWidth, int reqHeight) {
    // Raw height and width of image
    final int height = options.outHeight;
    final int width = options.outWidth;
    int inSampleSize = 1;

    if (height > reqHeight || width > reqWidth) {

        // Calculate ratios of height and width to requested height and width
        final int heightRatio = Math.round((float) height / (float) reqHeight);
        final int widthRatio = Math.round((float) width / (float) reqWidth);

        // Choose the smallest ratio as inSampleSize value, this will guarantee
        // a final image with both dimensions larger than or equal to the
        // requested height and width.
        inSampleSize = heightRatio < widthRatio ? heightRatio : widthRatio;


    return inSampleSize;

    public static Bitmap decodeSampledBitmapFromResource(String pathToFile,
                int reqWidth, int reqHeight) {

        // First decode with inJustDecodeBounds=true to check dimensions
        final BitmapFactory.Options options = new BitmapFactory.Options();
        options.inJustDecodeBounds = true;
        BitmapFactory.decodeFile(pathToFile, options);

        // Calculate inSampleSize
        options.inSampleSize = calculateInSampleSize(options, reqWidth, reqHeight);

        // Decode bitmap with inSampleSize set
        options.inJustDecodeBounds = false;
        return BitmapFactory.decodeFile(pathToFile, options);



With Glide library:


Glide does all the backend work.
