java - Cannot insert values into SQLite database in android -

I have three classes I is an activity that sends the text of EditTexts to another class:

  string [] comments = new string [] {number.getText (). ToString (), ship_name.gate text () ToString (), ...} / 20 such values ​​commented = datastart.Create comment (comment);   
 This class handles Comments:  
  private String [] allColumns = {MySQLiteHelper.COLUMN_ID, MySQLiteHelper.COLUMN_IMO_NUMBER, MySQLiteHelper.COLUMN_VESSEL_NAME,. ..} // 21 make such value public VesproModel comment (string comment []) {long insertId = 0; Int i = 1, j = 0; Cursor cursor = null; Material values ​​= new material value (); Values.put (allColumns [0], insertId); {Values.put (all columns [i], comment [j] for I & lt; allColumns.length & amp; amp; amp; & amp; j & lt; comment length; i ++, j ++) ); InsertId = database.insert (MySQLiteHelper.TABLE_TPCS_VESSEL, zero, value); Cursor = database.query (MySQLiteHelper.TABLE_TPCS_VESSEL, all columns, MySQLiteHelper.COLUMN_ID + "=" + insert, empty, empty, empty, zero); } Cursor.movetofst (); VesproModel newcomment = cursor output (cursor); Cursor.close (); Return new comment; } Private VesproModel cursorToComment (cursor cursor) {VesproModel Comment = New VesproModel (); Log D. ("Cursor changes comment", "before cursor tutorial"); If (cursor! = Null & cursor. Posterior tofest ()) {log d. ("Post-cursor comment", "comment inside cursor"); Comment.setId (cursor.getLong (0)); Comment.setImo_number (cursor.getString (1)); Comment.setVessel_name (cursor.getString (2)); Comment.setVessel_type (cursor.getString (3)); ... ... comment.setNo_engines (cursor.getINt (20)); } And Log D. ("Cursor Tutorial", "Zero Evaluation"); Remarks of return; }   
 VesproModel includes variables and their gates and setters. MySQLiteHelper class SQLiteOpenHelper class exxtends which handles the query to create a table called TPC_VESSEL error message displays Logkt:

 1 Edit : Create table command in the MySQLiteHelper class:  
  database. ExecSQL ("Table" + "TABLE_TPCS_VESSEL +" ("+ COLUMN_ID +" integer primary key autoincrement, "+ COLUMN_IMO_NUMBER +" text is not zero, "+ COLUMN_VESSEL_NAME +" text is meaningless, the text "+ COLUMN_VESSEL_TYPE +" is not zero, "+ COLUMN_SR_CERTIFICATE_NO +" The text is not empty, "+ ... .... COLUMN_NO_ENGINES +" is not an integer faucet); ";    
 
 
 The logkets say all this  
  TPCS_VESSEL vessel_name  may not be blank. It seems that you have given it to  null < / Code> declared when not created, then better Set a default value to form. Or take when entering a value in the variable
