Disable shared preferences entirely for directBootAware broadcast receiver #1188

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.content.ContextWrapper.getSharedPreferences(ContextWrapper.java:167)
	at android.preference.PreferenceManager.getDefaultSharedPreferences(PreferenceManager.java:526)
	at org.acra.prefs.SharedPreferencesFactory.create(SharedPreferencesFactory.java:40)
	at org.acra.ACRA.init(ACRA.java:25)
	at org.acra.ACRA.init(ACRA.java:10)
	at org.acra.ACRA.init(ACRA.java:9)
	at org.acra.ACRA.init(ACRA.java:5)
	at uk.org.xibo.player.Xibo.attachBaseContext(Xibo.java:4)
	at android.app.Application.attach(Application.java:189)
	at android.app.Instrumentation.newApplication(Instrumentation.java:1103)
	at android.app.Instrumentation.newApplication(Instrumentation.java:1087)
	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
