System Server crash with SQLiteDiskIOException

[anonwu]

Hi all:

When my device in low storage condition, the system server will crash.
From the log, it was caused by SettingsProvider.

"
E/AndroidRuntime( 178): at
android.database.sqlite.SQLiteOpenHelper.getReadableDatabase(SourceFile:
228)

E/AndroidRuntime( 178): at
com.android.providers.settings.SettingsProvider.query(SettingsProvider.java:
435)
"

But the default Settings provider not handle "SQLiteDiskIOException",
system will crash in some extremely condition.
I don't know why the "getReadableDatabase" method not force developer
to handle such exception? ex: "SQLiteDatabase getReadableDatabase()
throws SQLiteException". Any bad code can be checked in build time.

Or this thought may cause another problem?

Cheers

When storage is extremely low, content providers will be opened read-only.  This is a bad state to be in, that is why the notification is put up to have the user free up storage.  However ever release of Android goes through tests to ensure that you can boot and run a device in such a state enough to be able to go to settings and free storage.  If this is not working for you, my first assumption is that there is something different in your build from the base platform causing a problem.
