this is the most bizarre error I have ever seen, after I had error with database leaked I solve it by using static instance, now my activity crash but not every time only when I use it more than once and use another activity then back to it it will crash with the logcat below

the code of my activity when using this static instance is this

protected void onStart() {
        super.onStart();

        try {
            if (DBconnection.getInstance(getApplicationContext()).hasData("Standing")) {
                try {

                    StandingDataList = DBconnection.getInstance(getApplicationContext()).GetAllStanding();
                    Standing_adapter = new ExpandableAdapter(getApplicationContext(), StandingDataList);
                    Standing_ListView.setAdapter(Standing_adapter);
                    Standing_adapter.notifyDataSetChanged();
                } catch (Exception e) {
                    e.getMessage();
                }

and this is my database helper class 

public class DBconnection extends SQLiteOpenHelper {
    public static final String DBName="my.db";
    public static final int Version=1;
    private static DBconnection mInstance = null;



    public static DBconnection getInstance(Context ctx) {
        if (mInstance == null) {
            mInstance = new DBconnection(ctx.getApplicationContext());
        }
        return mInstance;
    }
    private DBconnection(Context context) {
        super(context, DBName, null, Version);

    }

I have searched a lot for a solution with no luck, so please any help will be precious

  • "this is the most bizarre error" -- nothing in those messages represents an error. Error messages start with `E/`; those start with `W/` (warning), `I/` (information), and `D/` (debug). – CommonsWare Feb 22 '16 at 20:37
  • after all the app is crashing as I mentioned, thanks for your information – Wael Abed Feb 23 '16 at 06:21
  • Then you need to find your Java stack trace associated with your crash: http://stackoverflow.com/questions/23353173/unfortunately-myapp-has-stopped-how-can-i-solve-this – CommonsWare Feb 23 '16 at 11:55

SEC is Samsung Electronic Corporation. It looks like a problem in their built in clock app, not in yours.
