This is the error because you have not added the class in your Android Manifest file. Try adding the class name i.e activity to your Manifest.xml and run it. It must work.. 
|
|
|
|
|
I thick you changed manifest.xml
in that see wheather the <activity android:name=".MainActivity">
is there

Hi All,
I am just developing one Android app, in which we have to capture the video. Now user will capture the video in portrait view but while it will play, it will automatically play in landscape.
i.e. video is capture in portrait view, though it will play in landscape view. when i will check in memory card, video is still captured in portrait view and also while playing video from memory card, it will play in portrait view.
I have checked, manifest file and seems all files are fine.
Please let me know if any one have any idea.
Regards
Keyur Satyadev

Hello,
I've been trying to make my first Android app.
I created a library project that cointain an activity called 'Reader':
public class Reader extends Activity {
private String ID;
public void setID(String id) {
ID = id;
}
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_reader);
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.activity_reader, menu);
return true;
}
}
also i created a (test) project that contain another activity called 'MainActivity':
public class MainActivity extends Reader {
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setID("bla_bla_bla");
}
}
when it comes to the GUI the inheritance is working well, i can see everything I placed in 'Reader' on 'MainActivity', but when it comes to using inherited methods such as 'setID(String)' i get a compilation error Eclipse Quote: The method setID(String) is undefined for the type MainActivity
How can it be?
thank you very much!!!

Have you tried using
super.setID("bla_bla_bla");

How do I add method for last_insert_rowid
I added a record to the table. As soon as it is entered I want to get the rowed that SQLite gave to it. How can I accomplish this?
|
|
|
|
|
You should be able to use last_insert_rowid for the last row id that was inserted for that connection. Basically, inside the same connection, issue a separate select command:
SELECT last_insert_rowid
|

Hi Pete,
I tried this and it wont let me compile. I don't know the correct syntax. There is not much out there for WP8 SQLite
string query = "select last_insert_rowid() as id from myTable";
using (var db = new SQLite.SQLiteConnection(System.IO.Path.Combine(ApplicationData.Current.LocalFolder.Path, "SM.db"), true))
{
SQLite.SQLiteCommand cmd = new SQLite.SQLiteCommand(db);
var result = cmd.ExecuteNonQuery();
}
|
|
|
|
|
No. Only select last_insert_rowid();. You don't need the rest. There's a reaaon I didn't include it in my answer there.
|
|
|
|
|
I tried that and I get this error
SQLite.SQLiteException: Misuse
|
|
|
|
|
I tried this also and the error is "Row"
SQLite.SQLiteCommand cmd = new SQLite.SQLiteCommand(db);
cmd.CommandText = query.ToString();
var result2 = cmd.ExecuteNonQuery();
|
|
|
|
|
If you're trying to retrieve the record, use ExecuteScalar, not ExecuteNonQuery.
|
|
|
|
|
Ok,
So what is the syntax for that?
cmd.ExecuteScalar< ? >;
Sorry, I just don't know SQLite
|
|
|
|
|
It should just be something like:
private int GetLastRowId(SQLLite.SQLLiteConnection connection)
{
SQLLite.SQLLiteCommand cmd = new (connection);
cmd.CommandText = "SELECT last_insert_rowid";
object rowId = cmd.ExecuteScalar();
return Convert.ToInt32(rowId);
}
|
|
|
|
|
|
|
Cursor cursor = getReadableDatabase().
rawQuery("select * from todo where _id = ?", new String[] { id });
