我正在使用cordova 3.3.0。在我的应用程序中，当我点击返回按钮时，一旦应用程序启动，应用程序就会崩溃。Phonegap Android应用程序崩溃，当点击返回按钮

我在主要活动中处理了后退按钮操作，但结果相同。

请发表您的代码。 –

Sid，它的理由是webview多数民众赞成它。我加载了像\t super.loadUrl（“file：///android_asset/www/index.html”）; –

你是否传递任何“上下文”？ –

公共类MainActivity扩展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 
public void init() { 
    Log.e(TAG, "init()"); 
    CordovaWebView webView = new CordovaWebView(MainActivity.this); 
    CordovaWebViewClient webViewClient; 
    if(android.os.Build.VERSION.SDK_INT < android.os.Build.VERSION_CODES.HONEYCOMB) 
    { 
     webViewClient = new CordovaWebViewClient(this, webView); 
    } 
    else 
    { 
     webViewClient = new IceCreamCordovaWebViewClient(this, webView); 
    } 
    this.init(webView, webViewClient, new MyCordovaChromeClient(this, webView)); 
} 

private class MyCordovaChromeClient extends CordovaChromeClient{ 
    private CordovaInterface cordova; 
    public MyCordovaChromeClient(CordovaInterface ctx, CordovaWebView app) { 
     super(ctx, app); 
     this.cordova = ctx; 
    }
