Try to use Project -> Clean. That actually helped me.
EDIT: If that doesn't help, try to relaunch Eclipse after Clean.

you are using a custom class - twowayview. fix you build path. check if you have checked the added jars in your build path. clean the project. delete bin folder.clear/refresh the project. it will work

Getting a DialogFragment to instantiate

I am new to Android.
Trying to show a dialog on press of a button like below using DialogFragments
File : Dialog2/LoginDialog.java
package com.kartnet.Dialog2;
import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.view.LayoutInflater;
import android.widget.Toast;
import android.content.Context;
import android.app.Dialog;
import android.content.DialogInterface;
import android.app.AlertDialog;
import android.app.DialogFragment;
import android.util.Log;
public class LoginDialog extends DialogFragment
{
#Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
AlertDialog.Builder ad_builder = new AlertDialog.Builder(getActivity());
//ad_builder.setMessage(R.string.login_dialog);
DialogInterface.OnClickListener ad_listener =
new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dlg1, int id) {
final String tag = "CustomDlg";
Log.d(tag, id + " clicked");
}
};
ad_builder.setTitle(R.string.btn_dialog_custom_title);
LayoutInflater linf = getActivity().getLayoutInflater();
ad_builder.setView(linf.inflate(R.layout.dialog_signin, null));
ad_builder.setNegativeButton("Cancel", ad_listener);
ad_builder.setPositiveButton("Ok", ad_listener);
return ad_builder.create();
}
}
File : Dialog2/Dialog2App.java
package com.kartnet.Dialog2;
import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.view.LayoutInflater;
import android.widget.Toast;
import android.content.Context;
import android.app.Dialog;
import android.content.DialogInterface;
import android.app.DialogFragment;
import android.app.AlertDialog;
import android.util.Log;
public class Dialog2App extends Activity
{
/* Called when the activity is first created. */
#Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
}
public void displayDialogCustom(View v)
{
LoginDialog ld = new LoginDialog(); /*<<=== FAILS with runtime exception */
// ld.show(getFragmentManager(), "login_dialog");
} /* displayCustomDialog */
}
Why should it fail at runtime, with no errors during compile time? Also, since both files are declared to be in the same package (com.kartnet.Dialog2), is there anything special I need to get these two java files to be in the application?
Here is what the error displayed

Based on the attached log, it appears you're trying to run the code on an older device which does not offer native support to Fragments:
Unable to resolve superclass of Lcom/kartnet/Dialog2/LoginDialog;
Above basically means that android.app.DialogFragment could not be resolved, which will happen on pre-Honeycomb (< Android 3.0 / API level 11) devices. You were probably looking for the backwards compatible Fragment classes that are part of the support library (in the android.support.v4.app.* package).
To migrate your code to the classes in the support libary, you should:
Set up the support library.
Change all android.app.DialogFragment references to android.support.v4.app.DialogFragment (and also any other Fragment classes you may be using).
Change your Activity to a FragmentActivity (also located in the support libary).

Use this dialog manager to display simple dialogs.
public class AlertDialogManager {
/**
* Function to display simple Alert Dialog
* #param context - application context
* #param title - alert dialog title
* #param message - alert message
* #param status - success/failure (used to set icon)
* - pass null if you don't want icon
* */
public void showAlertDialog(Context context, String title, String message,
Boolean status) {
AlertDialog alertDialog = new AlertDialog.Builder(context).create();
// Setting Dialog Title
alertDialog.setTitle(title);
// Setting Dialog Message
alertDialog.setMessage(message);
if(status != null)
// Setting alert dialog icon
alertDialog.setIcon((status) ? R.drawable.success : R.drawable.fail);
// Setting OK Button
alertDialog.setButton("OK", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
}
});
// Showing Alert Message
alertDialog.show();
}
}
In your activity you can use this
alert.showAlertDialog(MainActivity.this,"Header","Message", false);

Try this:
Properties->Java Build Path->Order and Export and check Android Private Libraries

You can try to create the dialog before you return it with
Dialog d = ad_builder.create();
return d;
to see if it fail to create the dialog.

DialogFragment are singletons, so you cannot do:
LoginDialog ld = new LoginDialog(); /*<<=== FAILS with runtime exception */
you should use LoginDialog.instantiate(...) method

Google Maps Android API v2 ClassNotFound Runtime error

EDIT: For those struggling with this, checkout this link. Follow it carefully, but it does work! The crucial part is using keytool to generate your SHA1 hash against your debug keystore. Also, don't forget to add one for release too!
I've been trying to setup Google Maps Android API v2 and after setting everything up as said I'm getting this runtime exception ClassNotFound:

Your Activity needs to extend FragmentActivity from the support library

FTP connection drivehq

I created an Android app which has an FTP connection, however when I start the app it says "unfortunately your app must stopped", and I can't find the problem.
I tried to enter local passive mode however it didn't help me, I also tried to run the app on my phone however it gave me the same message.

Look at the stack trace. It says you have a NullPointerException on line 32.
If I counted right, that's this line:
ftpclient.changeToParentDirectory();
Notice that your class member ftpClient is not instantiated; so it's still null when you try to call changeToParentDirectory() on it.
Adding ftpClient = new FtpClient( ... ) somewhere before this call should solve your problem. Add the correct parameters for the dots.

check if checkbox is checked return null pointer

I have this code for an expandable list, I want to have a checkbox in the childgroups of the list view, and check if one of the checkboxes is checked.
The problem is that when I check if the checkbox is checked I get a NULL Pointer Exception.
Can you please tell me whats wrong?
here's my code - I've edited the code to inflate a view of the child_row.xml that holds that checkbox but I still get that null pointer, what am I doing wrong?!?!

If you get a nullpointer on a certain line, something on that line is null. If it is the if(childBox.isChecked() line, probably childBox is null. Hard to say without the stack, but most probable cause is the line where you retrieve that checkbox.
final CheckBox childBox = (CheckBox) findViewById(R.id.childBOX);
Might be returning null, and this could be for several reasons. It could be your id is childBox instead of childBOX. Or that it is not in R.layout.list.
The best thing you can do is start debugging. What line is the error. Find the object that is null. Find out why it is null and if that is expected or not.

Instead of checking the childBox.isChecked() you can use the isChecked value. So your code would look like this:
#Override
public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
if(isChecked == true){
choosenGroup.setText("Shift Set");
}
}

Check your layout list.xml I think this layout may is missing android:id="#+id/childBOX" for Check Box or android:id="#+id/choosen" for TextView
Check the folowin sample
<CheckBox android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/childBOX"/>
<TextView android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/choosen"/>
