Mainly the application I am buiding should be able to insert the title, description time and date the title is created. This is the database table I have created
for inserting title, content, date and time for an journal application.
While I was executing " the error as journal table column does not have a date " error occurred.

According to your log, there is no column named "date" in your table, check it please.
I wrote code for example "SMS Retreiver API" https://developers.google.com/identity/sms-retriever/request

Help what do I do wrong?
I had same problem. First you need to generate a unique key (App Signature) that will identify message and your device. Once you generate key, your broadcaster will be able to detect message.
public class AppSignature extends ContextWrapper {
public static final String TAG = AppSignature.class.getSimpleName();
private static final String HASH_TYPE = "SHA-256";
public static final int NUM_HASHED_BYTES = 9;
public static final int NUM_BASE64_CHAR = 11;
public AppSignature(Context context) {
super(context);
}
/**
* Get all the app signatures for the current package
* #return
*/
public ArrayList<String> getAppSignatures() {
ArrayList<String> appCodes = new ArrayList<>();
try {
// Get all package signatures for the current package
String packageName = getPackageName();
PackageManager packageManager = getPackageManager();
Signature[] signatures = packageManager.getPackageInfo(packageName,
PackageManager.GET_SIGNATURES).signatures;
// For each signature create a compatible hash
for (Signature signature : signatures) {
String hash = hash(packageName, signature.toCharsString());
if (hash != null) {
appCodes.add(String.format("%s", hash));
}
}
} catch (PackageManager.NameNotFoundException e) {
Log.e(TAG, "Unable to find package to obtain hash.", e);
}
return appCodes;
}
private static String hash(String packageName, String signature) {
String appInfo = packageName + " " + signature;
try {
MessageDigest messageDigest = MessageDigest.getInstance(HASH_TYPE);
messageDigest.update(appInfo.getBytes(StandardCharsets.UTF_8));
byte[] hashSignature = messageDigest.digest();
// truncated into NUM_HASHED_BYTES
hashSignature = Arrays.copyOfRange(hashSignature, 0, NUM_HASHED_BYTES);
// encode into Base64
String base64Hash = Base64.encodeToString(hashSignature, Base64.NO_PADDING | Base64.NO_WRAP);
base64Hash = base64Hash.substring(0, NUM_BASE64_CHAR);
return base64Hash;
} catch (NoSuchAlgorithmException e) {
}
return null;
}
}
After this initiate this class in your firs activity.
Hope this will help you.
I get the following error when running my app using android studio.
Error
==============================================
java.lang.IllegalStateException: Couldn't read row 0, col -1 from CursorWindow. Make sure the Cursor is initialized correctly before accessing data from it.
My database is SQLite.
My app allows a user to register and login.
Sports app.
From here they can add "Players" to their team.
I have two tables set up in my db one for users and one for players with the "user_id" field from users table being used as the foreign key to link both dbs.
Basically only the logged in users who add a certain player can see that players information and not all others that other users created.
Originally the app was saving the players to the correct table.
However the foreign key was not getting filled.
I then re wrote the code to correct this.
However this is when i encountered this new problem.
Any help or advice at all is much appreciated.

I believe that your issue may be that your foreign key is acting as it should and that a conflict is being raised because the the player passed to the addPlayer method doesn't appear to have the user set (unless dome within the construction of the Player object).
That is user may well be null or some other value that is not a value that is stored in the User_id column in the User table.
That is you only appear to pass the email from activity to activity and then only use the checkUser (only returns a boolean) and the getColumnsUserName (only returns a String that appears to be the email that was found according to the email used as the search argument).
The User_id however MUST be an integer value for it to be a valid User_id column in the User table.
That is as the User_id column being defined using INTEGER PRIMARY KEY (with or without AUTOINCREMENT) is an alias of the hidden rowid column and MUST be an INTEGER value (SQLite Autoincrement P.S. additionally note the summary in regards to using AUTOINCREMENT).
Determining the issue
I would suggest placing a breakpoint on the line db.insert(TABLE_PLAYERS, null, values); in the DatabaseHelper and running in Debug, when the breakpoint is reached to then inspect the value of foreignId in the player object.
You may wish to read Debug your app
However, if the cause is as suspected I also believe that the Stack-trace should also indicate the CONFLICT.
Personally rather than passing the email from activity to activity I'd suggest passing the User_id value as this will be UNIQUE and is also the most efficient means to locate the respective row as per :-
The data for rowid tables is stored as a B-Tree structure containing
one entry for each table row, using the rowid value as the key. This
means that retrieving or sorting records by rowid is fast. Searching
for a record with a specific rowid, or for all records with rowids
within a specified range is around twice as fast as a similar search
made by specifying any other PRIMARY KEY or indexed value.
ROWIDs and the INTEGER PRIMARY KEY
Additonal
There are two issues that will each result in the index -1 issue.
The -1 issue itself is because the Cursor getColumnIndex method returns -1 if the column passed to the method does not exist in the Cursor (note a Cursor only has the columns that have been specified).
The first issue is with the line :-
user = cursor.getString(cursor.getColumnIndex("EMAIL"));
There is no such column in the user table so this would always fail. Changing this to :-
user = cursor.getString(cursor.getColumnIndex(COLUMN_USER_EMAIL));
will specify a column that is in the table.
The second issue is that although COLUMN_USER_EMAIL is a valid column in the table, that column is not included in the Cursor.
To include that column in the Cursor then change :-
String[] columns = {
COLUMN_USER_ID
};
to :-
String[] columns = {
COLUMN_USER_ID,
COLUMN_USER_EMAIL
};
or to :-
String[] columns = {"*" }; //<<<<<<<<<< * means ALL columns
or instead change :-
Cursor cursor = db.query(TABLE_USER,
columns,
selection,
selectionArgs,
null,
null,
null);
int cursorCount = cursor.getCount();
to
Cursor cursor = db.query(TABLE_USER,
null, //<<<<<<<<<< null equates to * and thus ALL columns
selection,
selectionArgs,
null,
null,
null);
So the app is now working correctly after a rebuild.
Pretty strange behavior but i wont complain.
Thanks for you help.
Eamon
I am using PrimeFaces 6.0 components:
<p:commandButton type="submit" value="Create Customer"
icon="ui-icon-check"
actionListener="#{newCustomerBean.saveNewCustomer}"
update = "#form"
oncomplete="ajaxUploadFile();"/>
<p:inputText id="saveCustomerId" value ="#{newCustomerBean.savedKundeId}"/>
and I want to execute the following sequence of actions with them:
1.) Execute the actionListener method on the backing bean to save a customer;
2.) Update the form field saveCustomerId with the id of the customer that is saved on step (1). The actionListener method generates a customer Id after the successful save and stores is as a bean property;
3.) Execute the Java Script method ajaxUploadFile()
According to the link
Execution order of events when pressing PrimeFaces p:commandButton
this sequence shall be as I have imagined.
However, in reality, the method
ajaxUploadFile()
is called BEFORE the input field with id saveCustomerId is updated.
Could you help me get the right sequence?
Here is the backing bean:
#ManagedBean
#ViewScoped
public class NewCustomerBean implements Serializable {
public enum KundeTyp {
TYP_NATPERS("Nat. Person"), TYP_FIRMA("Firma");
private String value;

private Map<String, KundeTyp> custmerTypes;
private long savedKundeId;
#Inject
private KundeDBService kundeService;
private String vorname;
private String addresse;
private String steuerNummer;
private String kundeTyp = Integer.MIN_VALUE + "";
#PostConstruct
public void init() {
custmerTypes = new HashMap<String, KundeTyp>();
custmerTypes.put(KundeTyp.TYP_NATPERS.value, KundeTyp.TYP_NATPERS);
custmerTypes.put(KundeTyp.TYP_FIRMA.value, KundeTyp.TYP_FIRMA);
}
public KundeTyp getCustmerType() {
return custmerType;
}
public void setCustmerType(KundeTyp custmerType) {
this.custmerType = custmerType;
}
public Map<String, KundeTyp> getCustmerTypes() {
return custmerTypes;
}
public void setCustmerTypes(Map<String, KundeTyp> custmerTypes) {
this.custmerTypes = custmerTypes;
}
public String getVorname() {
return vorname;
}
public void setVorname(String vorname) {
this.vorname = vorname;
}
public String getAddresse() {
return addresse;
}
public void setAddresse(String addresse) {
this.addresse = addresse;
}
public String getSteuerNummer() {
return steuerNummer;
}
public void setSteuerNummer(String steuerNummer) {
this.steuerNummer = steuerNummer;
}
public String getKundeTyp() {
return kundeTyp;
}
public void setKundeTyp(String kundenTyp) {
this.kundeTyp = kundenTyp;
}
public String saveNewCustomer(ActionEvent e) {
Kunde neuerKunde = null;
switch (this.custmerType) {
case TYP_NATPERS: {
neuerKunde = new NatuerlichePerson();
break;
}
case TYP_FIRMA: {
neuerKunde = new Firma();
((Firma) neuerKunde).setSteuerNummer("123456");
break;
}
}
neuerKunde.setVorname(vorname);
neuerKunde.setAdresse(this.addresse);
try {
savedKundeId = kundeService.saveKunde(neuerKunde);
} catch (ServiceException se) {
FacesContext.getCurrentInstance().addMessage(null, new FacesMessage(FacesMessage.SEVERITY_ERROR, "Error",
"Unable to save the new customer: " + se.getMessage()));
}
return null;
}
public long getSavedKundeId() {
return savedKundeId;
}
public void setSavedKundeId(long savedKundeId) {
this.savedKundeId = savedKundeId;
}
}
I would propose a work-around here, since I was not able to find a solution.
Instead of updating the customerId on the front-end, we put it as a session attribute in the HttpSession.
Then, in the UploadServlet, which handles the file upload, we read this attribute and save the image under this customerId.
I'm trying to call a BHO plugin function from javascript, that BHO injected to page.
But:
console.log(window.myExtension) is "none" or "undefined"
OnDocumentComplete fires not on each browser start. (it's because of IE?)
OnDocumentComplete not fires on F5, just if set cursor in address field and press Enter (and see 2nd)
