單擊后退按鈕時，Phonegap Android應用程序崩潰

Question

我正在使用cordova 3.3.0。在我的應用程序中，當我單擊“后退”按鈕時，一旦應用程序啟動，應用程序就會崩潰。

我已經在“主要活動”中處理了后退按鈕動作，但結果相同。

以下是崩潰。

公共類MainActivity擴展了DroidGap {

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    super.setIntegerProperty("loadUrlTimeoutValue", 60000); 
     new CordovaWebClient(this, appView);
    super.loadUrl("file:///android_asset/www/index.html");
}

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    // Inflate the menu; this adds items to the action bar if it is present.
    getMenuInflater().inflate(R.menu.main, menu);
    return true;
}

public void onReceivedSslError(WebView view,
                SslErrorHandler handler, SslError error) {
Log.e("Error", "Received SSL error"+ error.toString());
handler.proceed();
}
@Override

    CordovaWebView webView = new CordovaWebView(MainActivity.this);

    this.init(webView, webViewClient, new MyCordovaChromeClient(this, webView));

private class MyCordovaChromeClient extends CordovaChromeClient{
