Picasso producing OutOfMemoryError

Question

We are using Picasso to load all images in our app, from small avatars to large full screen images and we are getting 1 of these errors for every 10 daily active users. The Picasso cache is filling up, but our understanding that it should maintain itself.

Our logs indicate these errors are occurring most often when loading the large full screen images (1080x1920) and large avatars (720x720) on high end devices (Galaxy S4), but occasionally on small avatars (135x135).

Answer 1

I've had same issue and one of the temporary workarounds is

<application
    ...
    android:largeHeap="true">

For now, I haven't found another solution (maybe I've searched not enough). But many people have OOM with Picasso.
