Android onKeyLongPress when webview exists

Question

Regarding to that question and that question if you use onKeyDown and onKeyLongPress one need to use event.startTracking(); inside onKeyDown. But I use WebViews.

What can I do to join onKeyDown and onKeyPress while not losing WebView's back function ?
I need this behaviour:
Inside webview,
* When user presses back button, webview will go back in history
* When user long presses back key, finish() will be called

public boolean onKeyDown(int keyCode, KeyEvent event) {
     if (keyCode == KeyEvent.KEYCODE_BACK) {
         if(mWebView.canGoBack()) {
             mWebView.goBack();
         } else {
             super.onBackPressed();
         }
         return true;
      }
     return super.onKeyDown(keyCode, event);
 }

@Override
public boolean onKeyLongPress(int keyCode, KeyEvent event) {
    if (keyCode == KeyEvent.KEYCODE_BACK)
    {
        finish();
        return true;
    }
    return super.onKeyLongPress(keyCode, event);
}

You need to override the onBackPressed() method instead of onKeyDown(), which is called from onKeyUp() post-Eclair unless the target SDK is set to lower than Eclair. Returning true from onKeyLongPress() will cause the event to be cancelled, and onBackPressed() won't be called.

@Override
public void onBackPressed() {
    if(mWebView.canGoBack()) {
        mWebView.goBack();
    } else {
        super.onBackPressed();
    }
}

@Override
public boolean onKeyLongPress(int keyCode, KeyEvent event) {
    if (keyCode == KeyEvent.KEYCODE_BACK && event.isTracking()
            && !event.isCanceled() {
        super.onBackPressed();
        return true;
    }
    return false;
}

Edit: Actually you should override the onKeyUp() method instead to provide the same experience, and set a flag on the onKeyLongPress() call to check if it has been long pressed:

private boolean isBackKeyLongPressed;

@Override
public boolean onKeyUp(int keyCode, KeyEvent event) {
    if (keyCode == KeyEvent.KEYCODE_BACK && event.isTracking()
            && !event.isCanceled()) {
        if (!isBackKeyLongPressed && mWebView.canGoBack()) {
            mWebView.goBack();
        } else {
            onBackPressed();
        }
        isBackKeyLongPressed = false;
        return true;
    }
    if (keyCode == KeyEvent.KEYCODE_BACK) {
        isBackKeyLongPressed = false;
    }
    return super.onKeyUp(keyCode, event);
}

@Override
public boolean onKeyLongPress(int keyCode, KeyEvent event) {
    if (keyCode == KeyEvent.KEYCODE_BACK && !event.isCanceled()) {
        isBackKeyLongPressed = true;
    }
    return false;
}
