Question

I have a fairly simple app that takes the input from a user and then sets it as a notification. The user can create as many notifications as he/she likes. I want the user to click the notification and get taken to a new activity called ResultActivity. ResultActivity in turn reads in the putExtras from the notifications intent and shows it to the user. The code below allows me to do almost everything I wanted, except anytime a notification is pressed, I receive the putExtra of the last created notification.

Intent notificationIntent = new Intent(ctx, MainActivity.class);
PendingIntent contentIntent = PendingIntent.getActivity(ctx, i,notificationIntent,PendingIntent.FLAG_CANCEL_CURRENT);

NotificationManager nm = (NotificationManager) ctx.getSystemService(Context.NOTIFICATION_SERVICE);

Resources res = ctx.getResources();
NotificationCompat.Builder builder = new NotificationCompat.Builder(ctx);
builder.setContentIntent(contentIntent)
    .setSmallIcon(R.drawable.ic_launcher)
    .setLargeIcon(BitmapFactory.decodeResource(res,R.drawable.ic_launcher))
    .setTicker("Remember to " + text.getText())
    .setWhen(System.currentTimeMillis()).setAutoCancel(true)
    .setContentTitle(text.getText());

// Creates an explicit intent for an Activity in your app
Intent resultIntent = new Intent(this, ResultActivity.class);
String pass = text.getText().toString();

resultIntent.putExtra("title", pass);
resultIntent.putExtra("uid", i);

TaskStackBuilder stackBuilder = TaskStackBuilder.create(this);
// Adds the back stack for the Intent (but not the Intent itself)
stackBuilder.addParentStack(ResultActivity.class);
// Adds the Intent that starts the Activity to the top of the stack
stackBuilder.addNextIntent(resultIntent);
PendingIntent resultPendingIntent = stackBuilder.getPendingIntent(0,PendingIntent.FLAG_UPDATE_CURRENT);

new Uri.Builder().scheme("data").appendQueryParameter("text", "my text").build();
builder.setContentIntent(resultPendingIntent);

Notification n = builder.build();
n.flags = Notification.FLAG_NO_CLEAR;
nm.notify(i++, n);
text.setText(null);

1. Open the application

2. Type in “One”

3. Hit ok

4. Notification is sent

5. Open the application

6. Type in “Two”

7. Hit ok

8. Notification is sent

Now you have two notifications. One that says “One” and one that says “Two”. If you click on the notification “Two” it takes you to a screen that says “Two”. Perfect!

If you click on the notification “One” it takes you to a screen that says “Two”. BROKEN!

ResultActivity.java

public class ResultActivity extends Activity {
    String title = null;
    TextView text;

    int i=0;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        // TODO Auto-generated method stub
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity);
        text = (TextView) findViewById(R.id.textView1);



        title = getIntent().getStringExtra("title");
         i = getIntent().getIntExtra("uid", 0);


        text.setText(title);

    }

You create multiple intents that are mixed. I cleaned up the code (but did not test it)

    NotificationManager nm = (NotificationManager) ctx
            .getSystemService(Context.NOTIFICATION_SERVICE);

    Resources res = ctx.getResources();

    // Creates an explicit intent for an Activity in your app
    Intent resultIntent = new Intent(this, ResultActivity.class);
    String pass = text.getText().toString();
    resultIntent.setData(new Uri.Builder().scheme("data")
            .appendQueryParameter("text", "my text").build());
    resultIntent.putExtra("title", pass);
    resultIntent.putExtra("uid", i);

    TaskStackBuilder stackBuilder = TaskStackBuilder.create(this);
    // Adds the back stack for the Intent (but not the Intent itself)
    stackBuilder.addParentStack(ResultActivity.class);
    // Adds the Intent that starts the Activity to the top of the stack
    stackBuilder.addNextIntent(resultIntent);
    PendingIntent resultPendingIntent = stackBuilder.getPendingIntent(0,
            PendingIntent.FLAG_UPDATE_CURRENT);

    NotificationCompat.Builder builder = new NotificationCompat.Builder(ctx);
    builder.setSmallIcon(R.drawable.ic_launcher)
            .setLargeIcon(
                    BitmapFactory.decodeResource(res,
                            R.drawable.ic_launcher))
            .setTicker("Remember to " + text.getText())
            .setWhen(System.currentTimeMillis()).setAutoCancel(true)
            .setContentTitle(text.getText())
            .setContentIntent(resultPendingIntent);

    Notification n = builder.build();
    n.flags = Notification.FLAG_NO_CLEAR;
    nm.notify(i++, n);

    text.setText(null);
