    Fresco

    Fresco

    An Android library for managing images and the memory they use

    ...When the image goes off-screen, it automatically releases its memory. A decompressed image - an Android Bitmap - takes up a lot of memory. This leads to more frequent runs of the Java garbage collector. This slows apps down. The problem is especially bad without the improvements to the garbage collector made in Android 5.0. On Android 4.x and lower, Fresco puts images in a special region of Android memory. It also makes sure that images are automatically released from memory when they’re no longer shown on screen. ...

Unlike the emphasis on traditional text editing functions found in most mainline writing apps, neutriNote focuses instead on the long-term searchability of information...
