Can't transition from a Dialog to an Activity

Question

I can't seem to transition from a Dialog to an Activity and I was wondering if anyone is clever enough to figure out why!

This is the last bug I need to fix before submitting this project.

package com.mkyong.android;

import android.app.Activity;
import android.app.AlertDialog;
import android.content.Context;
import android.content.DialogInterface;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;

public class AppActivity extends Activity {

final Context context = this;
private Button button;

public void onCreate(Bundle savedInstanceState) {

    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);

    button = (Button) findViewById(R.id.button1);

    // add button listener
    button.setOnClickListener(new OnClickListener() {

    @Override
    public void onClick(View arg0) {

        AlertDialog.Builder alertDialogBuilder = new AlertDialog.Builder(
            context);

        // set title
        alertDialogBuilder.setTitle("Settings Menu");

        // set dialog message
        alertDialogBuilder
            .setMessage("Link or Delete?")
            .setCancelable(false)
            .setPositiveButton("Link",new DialogInterface.OnClickListener() {
        public void onClick(DialogInterface dialog,int id) {
            //start new activity

            Intent intentApp2Activity = new Intent(AppActivity.this, App2Activity.class);
            startActivity(intentApp2Activity);

            // if this button is clicked, close
            // current activity
            AppActivity.this.finish();
        }
      })
            .setNegativeButton("Delete",new DialogInterface.OnClickListener() {
                public void onClick(DialogInterface dialog,int id) {
                    // if this button is clicked, just close
                    // the dialog box and do nothing
                    dialog.cancel();
                }
            });

            // create alert dialog
            AlertDialog alertDialog = alertDialogBuilder.create();

            // show it
            alertDialog.show();
        }
    });
}

}

can you please explain what issue are you facing and is there any exception — Karan_Rana, Mar 02 '13 at 08:14
Apologies - Force Close after clicking "Link" (which is supposed to transition to the other activity) — Guy Richards, Mar 02 '13 at 08:17
Post the logcat stack trace please. BTW, the "paypal" thing is neither wanted nor desired. I've edited it out. This is a free community managed by volunteers for the good of the community. — Simon, Mar 02 '13 at 08:17
@AmaniSwann : make sure u have added App2Activity Activity in AndroidManifest.xml file. if yes then u have issue inside App2Activity Activity instead of AppActivity .so u will need to add App2Activity class code with Log cat trace — ρяσѕρєя K, Mar 02 '13 at 08:19
It's already in the Manifest and I can access it successfully independently and via 2 other buttons - just not the dialog script. LOG CAT: https://docs.google.com/file/d/0Bzs014LBJ1sWMjRPT1VwOEdQNWc/edit?usp=sharing — Guy Richards, Mar 02 '13 at 08:21

http://stackoverflow.com/questions/1124788/java-unresolved-compilation-problem - does your code even compile? — Code Painters, Mar 02 '13 at 08:27
Add this line in your imports:.. import android.content.Intent; — Karan_Rana, Mar 02 '13 at 08:31

Make sure that you have imported android.content.Intent, clean your project and rebuild.

This is a flaky piece of Android. As the exception hints, you have an unresolved compile time problem which should produce a compile time error. Smells like a bug in the ADT or Eclipse (I assume that you are using Eclipse) to me.
