android.database.sqlite.SQLiteConstraintException: error code 19: constraint failedexception

Question

I created a table named resources but when I insert values in it, this exception is thrown:

android.database.sqlite.SQLiteConstraintException:
error         


        

Answer 1

In order to get more information about SQLite errors, one can use ADB dumpsys:

adb shell dumpsys dbinfo -v

combined with grep:

adb shell dumpsys dbinfo -v | grep executeForLastInsertedRowId

or grep'ed twice:

adb shell dumpsys dbinfo -v | grep executeForChangedRowCount | grep failed

Answer 2

Constraint failed usually indicates that you did something like pass a null value into a column that you declare as not null when you create your table.
