Android : Maximum allowed width & height of bitmap

Question

Im creating an app that needs to decode large images to bitmaps to be displayed in a ImageView.

If i just try to decode them straight to a bitmap i get the following

Answer 1

this will decode and scale image before loaded into memory,just change landscape and portrait to the size you actually want

BitmapFactory.Options options = new BitmapFactory.Options();
options.inJustDecodeBounds = true;
BitmapFactory.decodeFile(path, options);
int imageHeight = options.outHeight;
int imageWidth = options.outWidth;
String imageType = options.outMimeType;
if(imageWidth > imageHeight) {
    options.inSampleSize = calculateInSampleSize(options,512,256);//if landscape
} else{
    options.inSampleSize = calculateInSampleSize(options,256,512);//if portrait
}
options.inJustDecodeBounds = false;
bitmap = BitmapFactory.decodeFile(path,options);

method for calculating size

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;
}
