Answer 1

You have the following NOT NULL values in your database definition:

CONTENT
PATH
VIDEO
TIME

But in your addDB you only put CONTENT and TIME in ContentValues so it definitely looking for PATH and VIDEO too. If they aren't present, it will give the error. There are two solution:

Solution 1:

remove NOT NULL constraint from VIDEO and PATH:

        db.execSQL("CREATE TABLE " + TABLE_NAME + "(" + ID
            + " INTEGER PRIMARY KEY AUTOINCREMENT," + CONTENT
            + " TEXT NOT NULL," + PATH
            + " TEXT," + VIDEO
            + " TEXT," + TIME
            + " TEXT NOT NULL)");

Solution 2:

add VIDEO and PATH to ContentValues:

private void addDB() {
    ContentValues cv = new ContentValues();
    cv.put(SecretAlbumDB.CONTENT, editText.getText().toString());
    cv.put(SecretAlbumDB.TIME, getTime());
    cv.put(SecretAlbumDB.VIDEO, getVideo());
    cv.put(SecretAlbumDB.Path, getPath());

    dbWriter.insert(SecretAlbumDB.TABLE_NAME, null, cv);
}

Answer 2

For sure you have declared your all fields (columns) as NOT NULL and you've not put the value to those fields while inserting cv. Either make those columns null acceptable or put all the values to cv for every Columns that are NOT NULL.
