Recent changes made in Google Play Store have affected the process of how the client manages download requests. The early version permitted to implement multiple downloads simultaneously. Now Play Store requires just one at a time. This is the reason why the error message pops up. Other apps are just pending for download. However there is a simple way to fix the issue. We will show it below.
First, you need to clear the download queue to make sure there are no interferences. In doing so, go to Play Store and swipe in the middle of the screen from right edge. Select "My apps and games" option. Tapping the downloaded app will let you access to the X button that you can use to clear download queue.
Some users manage to get rid of the issue following the above instruction. If it’s not the case you have to navigate your device Settings menu, then go to Play Store. On Play Store page select Clear Cache and Clear Data functions. In doing so, you will delete only Play Store info data. Hence you should not worry about losing important files. If you use Marshmallow or later Android versions, select "Storage", and then clear cache and data from that page.
If you still have trouble and fail to download an app, you have to employ Force stop Google Play. To do so, follow the steps:
- Navigate Settings;
- Select Play Store in Apps menu;
- Tap Force stop.
Following all instructions above, you will definitely get rid of the issue in near future. If the issue shows up again, you can always repeat these steps once more.
