I am learning android yet and not expert. I think I have some logic issue in handle my sqllite database. Let me explain what I am doing and what I am getting.
I have one application of quotes. I am providing local database as well online. I have included database file in Assets and copying database from it during first time when user open application from splash screen. After that I am checking last author and last quote number of local database which are stored in user's device and comparing with online database. If there new data in online then I am downloading and storing it in splash screen.
Now my splash screen code for do same is like below
DAO database=DAO.getInstance(this);
int lastAuthor =database.getLastAuthor();
String updatesUrl = constant.MainUrl + String.valueOf(lastAuthor)+ "/" + String.valueOf(lastQuote);
My DAO class is looking like this
public class DAO {
private SQLiteDatabase database;
private DBHandler dbHandler;
private static final String TABLE_QUOTES = "quotes";
private static final String TABLE_AUTHORS = "authors";
private static final String TABLE_SETTINGS = "settings";
private static final String QU_ID = "_quid";
private static final String QU_TEXT = "qu_text";
private static final String QU_AUTHOR = "qu_author";
private static final String QU_FAVORITE = "qu_favorite";
private static final String QU_TIME = "qu_time";
private static final String AU_NAME = "au_name";
private static final String AU_PICTURE = "au_picture";
private static final String AU_PICTURE_SDCARD = "au_picture_sdcard";
private static final String AU_WEB_ID = "au_web_id";
private static DAO dBObject;
private final Object lockObj=new Object();
public static DAO getInstance(Context context){
if(dBObject==null)dBObject=new DAO(context);
return dBObject;
}
private DAO(Context context) {
synchronized (lockObj) {
dbHandler = new DBHandler(context);
try {
dbHandler.createDataBase();
} catch (IOException e) {
e.printStackTrace();
}
dbHandler.openDataBase();
open();
}
}
public int getLastAuthor() {
String query = "SELECT " + AU_WEB_ID + " FROM " + TABLE_AUTHORS
+ " ORDER BY " + AU_WEB_ID + " DESC LIMIT 1";
Cursor cursor = database.rawQuery(query, null);
cursor.moveToFirst();
int tmp = cursor.getInt(cursor.getColumnIndex(AU_WEB_ID));
cursor.close();
return tmp;
}
// ==============================================================================
public int getLastQuote() {
String query = "SELECT " + QU_ID + " FROM " + TABLE_QUOTES
+ " ORDER BY " + QU_ID + " DESC LIMIT 1";
Cursor cursor = database.rawQuery(query, null);
cursor.moveToFirst();
int tmp = cursor.getInt(cursor.getColumnIndex(QU_ID));
cursor.close();
return tmp;
}
// ==============================================================================
public void addAuthor(String au_name, String au_picture, int au_web_id) {
open();
ContentValues v = new ContentValues();
v.put(AU_NAME, au_name);
v.put(AU_PICTURE, au_picture);
v.put(AU_PICTURE_SDCARD, 1);
v.put(AU_WEB_ID, au_web_id);
database.insert(TABLE_AUTHORS, null, v);
}
// ==============================================================================
public void addQuote(String qu_text, int qu_author, int _quid, String qu_time) {
open();
ContentValues v = new ContentValues();
v.put(QU_TEXT, qu_text);
v.put(QU_AUTHOR, qu_author);
v.put(QU_FAVORITE, "0");
v.put(QU_ID, _quid);
v.put(QU_TIME, qu_time);
database.insert(TABLE_QUOTES, null, v);
}
// ==============================================================================
//method changed
private void open() throws SQLException {
if(database!=null&&database.isOpen())return; //changed line
database = dbHandler.getWritableDatabase();
}
// ==============================================================================
public void closeDAO(){
synchronized (lockObj){
if(dbHandler!=null)dbHandler.close();
dbHandler=null;
database=null;
}
}
public static void dispose(){
if(dBObject!=null){
dBObject.closeDAO();
}
dBObject=null;
}
}
And My database handler class looking like this
public class DBHandler extends SQLiteOpenHelper {
private static String DB_PATH;
private static String DB_NAME = "xxx";
private SQLiteDatabase myDataBase;

try {

}
if (checkDB != null) {

However application does not getting crashed and working fine as I
need. But This errors are confusing me what I need to change for
resolve this errors. I am trying to solve from last two days but not
found any working solution for it. Let me know if any senior developer
can help me for come out from this. Thanks
If you are not already using a bundled database with your apk, you have not actually created the database here in your code.
#Override
public void onCreate(SQLiteDatabase db) {
//you must create the database here
}
// ==============================================================================
#Override
public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) {
//Handle the database update here
}
You need to do something like this.
#Override
public void onCreate(SQLiteDatabase db) {
try {
db.execSQL(CREATE_STRING);
} catch (SQLException e) {
e.printStackTrace();
}
Log.e(TAG, "Table Created");
}
#Override
public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) {
db.execSQL("DROP TABLE IF EXISTS " + TABLE_NAME_STRING);
onCreate(db);
Log.d(TAG, "Table upgraded to Version :" + newVersion);
}
I would also recommend to start using ROOM Android Architecture Component, which provides much better abstraction level for the Sqlite for the pattern are using.
I have create the recycerview and this recycerview display the Person image ,person name and + button when i have press + button change the button image like true.and after recycerview bottom one button this button click all data show the next activity..

First you should implement Serializable interface in your Build model class like this :-
public class Build implements Serializable{
//Content will be as it is
}
Change your clickListener like this :-
holder.button.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
build.setSelected(!build.isSelected());
if (build.isSelected()) {
holder.button.setBackgroundResource(R.drawable.selected_true_icon_new);
Intent intent = new Intent(context, youractivity.class)
intenet.putExtra("build",build);
context.startActivity(intent);
} else
holder.button.setBackgroundResource(R.drawable.add_button_icon);
}
});
In the onCreate method of receiving activity write this :-
Build build = (Build) getIntent().getSerializableExtra("build");
Add Intent in below Method,
holder.button.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
build.setSelected(!build.isSelected());
if (build.isSelected()) {
holder.button.setBackgroundResource(R.drawable.selected_true_icon_new);
Intent intent = new Intent(context, youractivity.class)
intenet.putExtra("key","value");
context.startActivity(intent);
} else
holder.button.setBackgroundResource(R.drawable.add_button_icon);
}
});
Huge mistak that you register to the click event on your ViewHolder! you will get diffrent position from the actual because when android use notifyItemMoved the viewBindHolder will not be called and than you got the wrong position.
and in the click listener implementation you should pass Intent with your data
I am creating an android app (still the basic structure, without any design) from an Job site through XML feed using REST api.
Till now, I could managed to parse the XML data, displaying the List View with an POP UP menu item on each row. I am passing Data from PostBaseAdapter to MarkAsFav class. Could You please tell me if I am doing right or not? coz, I am getting no any data saved in database
Now, I have a problems:
I have 3 pop up menu item:
1. Set as Favourite
2. Share on Fb
3. email to Your friend
I am working on point number-1.
For now,I would be saving the data in SQLite Database itself. so, I am passing all the data (all the details about the job with all rows) to another activity, more over I am accepting a user given name to save the details through insertDB() in my Database.
But, unfortunately , nothing is getting saved in the database .
Can you tell me, if the data is getting passed or not and if the datas are being saved in database or not?
Please help me out. Please tell me where and how to modify the code?

How to fix this error and use Asynctask in my application? tnx <3
Create your database tables in the onCreate of your DBHandler class.(Replace table name and columns)
