FATAL EXCEPTION: main java.lang.OutOfMemoryError at android.graphics.BitmapFactory.nativeDecodeStream(Native Method)

Question

I keep getting this error when I run my app. The app will compile fine and once I start interacting with it (ImageSlider) sometimes it breaks and comes up with that message.

Answer 1

if anyone trying to get images from sqlite and getting outOfMemory error try following :

cursor = adapter.getAllrecords(); //get your table records in cursor

//moving to the current position in cursor 
cursor.moveToPosition(position);

byte [] image = cursor.getBlob(cursor.getColumnIndex("image"));

 BitmapFactory.Options options = new  BitmapFactory.Options();
 options.inJustDecodeBounds = true;
 bitmapImage = BitmapFactory.decodeByteArray(image, 0, image.length, options);
 imageView.setImageBitmap(decodeSampledBitmapFromResource(80, 80));//pass height and             
                                                      //width as per your requirement 



public  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) {

            final int halfHeight = height / 2;
            final int halfWidth = width / 2;

// Calculate the largest inSampleSize value that is a power of 2 and keeps both
// height and width larger than the requested height and width.
             while ((halfHeight / inSampleSize) > reqHeight
                    && (halfWidth / inSampleSize) > reqWidth) {
                inSampleSize *= 2;
            }
        }

        return inSampleSize;
    }
        public  Bitmap decodeSampledBitmapFromResource(int reqWidth, int reqHeight) {

            // First decode with inJustDecodeBounds=true 
                to check dimensions
            final BitmapFactory.Options options = new BitmapFactory.Options();
            options.inJustDecodeBounds = true;
            BitmapFactory.decodeByteArray(image, 0, image.length, options);

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

            // Decode bitmap with inSampleSize set
            options.inJustDecodeBounds = false;
            return BitmapFactory.decodeByteArray(image, 0, image.length, options);
        }

this code worked for me..however according to developer guideliness we should handle image related task using AsyncTask...we should not run it on UI thread.
