Problems downloading and installing apps can prove to be a particular irritation. Perhaps it’s a game you’ve been downloading over Wi-Fi due to its size, only to find an error code accompanying a message informing you that the download failed. For large games, this is really annoying.
Many errors can sometimes be resolved by wiping the Google Play cache. Start by opening Settings> Apps, find the tab for All and look for Google Play Services. Tap Force Stop and when the app stops, go to Storage and tap Clear Cache.
You should repeat this action for Google Services and Google Framework Services, and perhaps even Download Manager. Once you have completed this, restart your Android device. Note that once you reboot, you may be required to re-enter your Google Play account credentials for verification.
Subsequent attempts to install apps should now work, but rather than heading straight for a large download, try a smaller file first, just in case.
