Fit cannot be used with get.

Error message

Fit cannot be used with get.

What it means

Thrown by RequestCreator.get() when the chain called fit(). fit() marks the request as deferred so it can wait for the target ImageView to be measured at layout time; get() is a synchronous, target-less API, so the two are fundamentally incompatible and Picasso throws IllegalStateException.

Solutions

1. Remove fit() before get(), and specify explicit sizing instead: .resize(w, h).centerInside().get()
2. If the image is destined for an ImageView, use into(imageView) and keep fit()
3. For prefetching, drop fit() and use fetch(), or get() with resize() matching the view size

Example fix

// before
Bitmap bmp = picasso.load(url).fit().get(); // throws "Fit cannot be used with get."

// after
Bitmap bmp = picasso.load(url).resize(1080, 1920).centerInside().get();

RequestCreator rc = picasso.load(url);
if (needSync) {
    Bitmap bmp = rc.resize(width, height).centerInside().get(); // no fit()
} else {
    rc.fit().into(imageView);
}

When it happens

Trigger: Calling picasso.load(url).fit().get(), e.g. to prefetch/measure the bitmap synchronously on a background thread while reusing fit() from an into() chain.

Common situations: Copying an into(imageView) chain (which used fit()) into a background preheat method that calls get(); adapting widget/AppWidget code that needs the Bitmap directly; unit-test helpers that synchronously load via get().
