How to resize the captured image in android

Question

When I am working on my Photo Editor Android application, after capturing the image from the camera through the app, I am resizing the image and then saving the image in the Gallery/Photos folder in the phone

Following is the HomeActivity code:

package com.saashtechs.photoeditor;

So when I capture the image and then when the user is taken to edit the application, it doesn't, it takes me back to Home page again after capturing the image

Error log is:

Can you please tell me where am I going wrong ?

Thanks in advance

Answer 1

add in your onActivityResult

after:

image = Bitmap.createScaledBitmap(image, 300, 300, false);

image = resizeBitmap(image, 300);

you can change size to anySize u want

add this in you class: send bitmap and maximum size and get bitmap

public Bitmap resizeBitmap(Bitmap getBitmap, int maxSize) {
    int width = getBitmap.getWidth();
    int height = getBitmap.getHeight();
    double x;

    if (width >= height && width > maxSize) {
        x = width / height;
        width = maxSize;
        height = (int) (maxSize / x);
    } else if (height >= width && height > maxSize) {
        x = height / width;
        height = maxSize;
        width = (int) (maxSize / x);
    }
    return Bitmap.createScaledBitmap(getBitmap, width, height, false);
}
