Is battery optimization enabled? [Android 6.0 or later]

Battery optimization (Doze mode) has been implemented as a new feature of Android 6.0. Battery optimization is a function that reduces battery drain by disabling network access for each app during sleep. This Widget App uses network access to receive score data during sleep, so if the battery optimization function is enabled, automatic updates will not be possible during sleep.

Countermeasure

This Widget App will be able to communicate even during sleep by excluding it from battery optimization. See below for how to do this.
1. Touch “App optimization”

2. Then follow the displayed guidelines to disable battery optimization.

Is Data Saver enabled? [Android 7.0 or later ]

Data Saver has been implemented as a new feature since Android 7.0. Data saver is a function that can save data traffic by blocking “background communication”(*). This Widget App receives each data via background communication, so the app will not be able to receive data if Data saver is enabled.
(*): Communication performed by app even when a user is not operating a device.

Countermeasure

By excluding this Widget App from Data saver, the app will be able to communicate in background as well. See below for how to do this.
1. Touch “App optimization”

2. Then follow the displayed guidelines to disable battery optimization.

Is a communication control app enabled?

Some communication control apps disable background communication. This Widget App receives each data via background communication, so the app will not be able to receive data if background communication is disabled by a communication control app.

Countermeasure

Exclude this Widget App from the target of traffic control.

* The setting method differs depending on a communication control app, so please refer to the help of the communication control app.
