Sometimes, for some things or for others, an application does not feel like starting. To try to solve this we can do several things:
- Close the application from multitasking if it continues to work
- Clear the application cache. To do this we will enter Settings> Applications and select the application that we want. Once inside, we will click on the "Clear cache" button.
- If this does not work try to delete the data of this application, option that is given in the same route previously written a little above where is the button of the cache.
- Uninstall the application and reinstall it.
If after this the application still fails to boot it is possible that it is due to a fault between the application and your device. Notify in comments on Google Play and maybe the developer can solve your problem.
