Anwendung stürzt unter Last Browser

Question

Ich versuche, die Browser-Funktion in meiner Android-Anwendung zu arbeiten, aber die Anwendung stürzt beim Laden ab. Hier ist der Code, wenn die neue Tätigkeit geladen wird:

@Override 
public void onCreate(Bundle savedInstanceState) { 
    WebView webview = new WebView(this); 
    setContentView(webview); 

    webview.loadUrl("http://erik-edgren.nu/weather"); 
    getWindow().requestFeature(Window.FEATURE_PROGRESS); 

    WebSettings webSettings = webview.getSettings(); 
    webSettings.setJavaScriptEnabled(true); 
} 

Und hier ist der LogCat:

Wie kann ich dieses Problem beheben?

Answer 1

Versuchen Sie dieses, Und lassen Sie mich wissen, was passieren

@Override 
public void onCreate(Bundle savedInstanceState) { 
super.onCreate(savedInstanceState); 

getWindow().requestFeature(Window.FEATURE_PROGRESS); 
    WebView webview = new WebView(this); 
    WebSettings webSettings = webview.getSettings(); 
    webSettings.setJavaScriptEnabled(true); 
    setContentView(webview); 

    webview.loadUrl("http://erik-edgren.nu/weather"); 
} 

Answer 2

Der Fehler sagt requestFeature() must be called before adding content. Versuchen Sie, diese (auch hinzugefügt, um die super.onCreate Aufruf):

@Override 
public void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstancsState); 
    WebView webview = new WebView(this); 

    getWindow().requestFeature(Window.FEATURE_PROGRESS); 

    WebSettings webSettings = webview.getSettings(); 
    webSettings.setJavaScriptEnabled(true); 

    setContentView(webview); 
    webview.loadUrl("http://erik-edgren.nu/weather"); 
}
