Webview Capturing Causes Out Of Memory Exception
i am loading html data into webview , after that i need to capture webview data and stored that image into sd card. Its working fine for small images, but it gives out of memory ex
Solution 1:
like @varan said, try to decode the image:
public static Bitmap decodeSampledBitmapFromResource(Resources res, int resId,
int reqWidth, int reqHeight) {
// First decode with inJustDecodeBounds=true to check dimensions
final BitmapFactory.Options options = new BitmapFactory.Options();
options.inJustDecodeBounds = true;
BitmapFactory.decodeResource(res, resId, options);
// Calculate inSampleSize
options.inSampleSize = calculateInSampleSize(options, reqWidth, reqHeight);
// Decode bitmap with inSampleSize set
options.inJustDecodeBounds = false;
return BitmapFactory.decodeResource(res, resId, options);
}
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 stretch_width = Math.round((float)width / (float)reqWidth);
int stretch_height = Math.round((float)height / (float)reqHeight);
if (stretch_width <= stretch_height) return stretch_height;
else return stretch_width;
}
I don't know how to do it in your special case from Picture to Bitmap, so if someone else knows feel free to edit this post.
