Android Check if the storage space is low on app boot

Question

I think I can use Intent.ACTION_DEVICE_STORAGE_LOW within a broadcast receiver to notify me when the device storage is low. Explained here.

I know that I could find out how much space the user has available here.

However, I want to avoid having to set a boundary of what is/isn't enough space available if possible. The OS gives the user a notification when the storage is low.

Question: Is there anyway of only showing an in app error message on boot if the OS thinks the space available is low?

Answer 1

Per some related sample code from google you can take this route:

IntentFilter lowstorageFilter = new IntentFilter(Intent.ACTION_DEVICE_STORAGE_LOW);
boolean hasLowStorage = registerReceiver(null, lowstorageFilter) != null;

In other words, there is a DeviceStorageMonitorService service that runs at the OS level and detects a low storage situation. From there, it sends a sticky broadcast that any activity or service can check, later. In this example, they registered a null receiver as a way to just test if the sticky broadcast has been sent.
