I got the error below:

The relevant code:
DbHelper.java

}

ApplicationConstant.java

myDbHelper = new DbHelper(context);

}
}

I am using splash screen to load the database initially.
Splash.java line 35:
try {
ApplicationConstant app = (ApplicationConstant) getApplication();
app.ReadyApplicationDatabase(Splash.this);
} catch (Exception e) {
e.printStackTrace();
Mint.logExceptionMessage("splash", "EnrollDevice204", e);
}
The app runs perfectly on other devices.I tried each and every solutions but ended up with no result.Please help.
