Leider hat meine Webview App in Marshmallow gestoppt

Question

Ich entwickle eine WebView-Anwendung in Android. Es funktioniert gut in Android Lollipop oder es ist niedrigere Versionen. Aber wenn ich versuche, die gleiche Anwendung in Marshmallow zu starten, gibt es den Fehler "Leider gestoppt".

Hinweis: Ich habe die Frage mit meinem Code aktualisiert.

Dies ist meine Manifest-Seite.

     <activity

    </application> 
</manifest> 

Dies ist build.gradle Datei

apply plugin: 'com.android.application' 
android { 
    compileSdkVersion 23 
    buildToolsVersion "23.0.2" 
    defaultConfig { 
     applicationId "com.xamarin.gcmexample" 
     minSdkVersion 11 
     targetSdkVersion 23 
     versionCode 1 
     versionName "1.0" 
    } 
    buildTypes { 
     release { 
      minifyEnabled false 
      proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro' 
     } 
    } 
} 
dependencies { 
    compile fileTree(dir: 'libs', include: ['*.jar']) 
    testCompile 'junit:junit:4.12' 
    compile 'com.android.support:appcompat-v7:23.2.1' 
    compile 'com.android.support:design:23.2.1' 
    compile 'com.google.android.gms:play-services:8.4.0' 
}

Answer 1

Sie können dies als

Ihrer Tätigkeit innerhalb onCreate tun

webView.getSettings().setJavaScriptEnabled(true); 
    webView.setWebViewClient(new MyWebViewClient()); 
    webView.loadUrl("your url link"); 

Und dann

private class MyWebViewClient extends WebViewClient{ 

    @Override 
    public boolean shouldOverrideUrlLoading(WebView view, String url) { 
     webView.loadUrl("your url link"); 
     return true; 
    } 

    @Override 
    public void onPageStarted(WebView view, String url, Bitmap favicon) { 
     super.onPageStarted(view, url, favicon); 
     ....code here 
    } 

    @Override 
    public void onPageFinished(WebView view, String url) { 
     super.onPageFinished(view, url); 
     .... code here 
    } 

    @Override 
    public void onReceivedError(WebView view, WebResourceRequest request, WebResourceError error) { 
     super.onReceivedError(view, request, error); 
     ,.....code here 
    } 
} 

Ich hoffe, es kann Ihnen helfen.
