Question

Trying to downgrade my appl from android 2.2 (API 8) down to android 2.1 (API7), I’m facing some issues with dialog boxes. Based on this thread, I’m trying to catch these exceptions but can’t override the showDialog method.

I turned the Java compiler from 1.5 to 1.6 according to this answer to a similar issue, but no changes, Eclipse still returns :

Cannot override the final method from Activity

public class MyActivity extends Activity implements
        SeekBar.OnSeekBarChangeListener {


// ... some stuffs

    @Override // here is the issue
    public void showDialog(int dialogId) {
        try {
            super.showDialog(dialogId);
        } catch (IllegalArgumentException e) {
            Log.e(ACTIVITY_TAG, "Error dialog");
        }
    }
    @Override
    protected Dialog onCreateDialog(int id) {

        switch (id) {
        case DIALOG_ALERT:
            // Create out AlertDialog
            Builder builder = new AlertDialog.Builder(this);
            builder.setMessage(msg);
            builder.setCancelable(false);
            builder.setPositiveButton(GOTO_BOOK, new OkOnClickListener());
            builder.setNegativeButton(STAY_HERE, new CancelOnClickListener());
            AlertDialog dialog = builder.create();
            dialog.show();
            break;
        case DIALOG_ONCREATE:
            // Create out AlertDialog during the "onCreate" method (only "Ok"
            // button)
            Builder builder2 = new AlertDialog.Builder(getParent());
            builder2.setMessage(msg);
            builder2.setCancelable(false);
            builder2.setPositiveButton(GO_BACK, new OkOnClickListener());

            AlertDialog dialog2 = builder2.create();
            dialog2.show();
            break;
        }

        return super.onCreateDialog(id);

    }

    // ... some stuffs

    }

Answer 1

onCreateDialog should not show the dialog , show part will be done by framework. All you need to do is return the correct dialog.

Remove the override part. You dont need a workaround for this issue. There is problem in your code

Remove

dialog.show();

Also Instead of this

return super.onCreateDialog(id);

use

return dialog;
