Disable shared preferences entirely for directBootAware broadcast receiver

[dasgarner]

Hey,

Firstly thanks for the great library!

I am using it in an application which sometimes interacts with USB devices and as such I have a receiver defined for the android.hardware.usb.action.USB_DEVICE_ATTACHED event. This receive needs to have android:directBootAware="true" to detect USB devices which are already attached on boot.

For quite some time we've had reports of our devices showing a "Xibo has stopped" dialog immediately on boot, and finally managed to track it down to the above receiver.

Caused by: java.lang.IllegalStateException: SharedPreferences in credential encrypted storage are not available until after user is unlocked
	at android.app.ContextImpl.getSharedPreferences(ContextImpl.java:387)
	at android.app.ContextImpl.getSharedPreferences(ContextImpl.java:372)

	at android.app.LoadedApk.makeApplication(LoadedApk.java:983)

Because the app process is being created by the receiver, ACRA init is being called, which is loading SharedPreferences - but the encrypted storage isn't unlocked yet.

My question is whether there is a way to completely disable the reading of shared preferences - accepting that we would not get them in our reports. (I think no, as they are always loaded in init)

Any help would be much appreciated!

Thanks,
Dan

Hi @dasgarner, there was an attempt to add direct boot support to ACRA, but the author went unresponsive so it never got merged. You could pick it up: #889

Thanks for the reply - I'll take a look at that PR and see what they did.
