import android.os.Bundle;
import android.app.Activity;
import android.view.Window;
import android.webkit.WebChromeClient;
import android.webkit.WebView;
import android.webkit.WebViewClient;

public class Gossipmate extends Activity 
{
    final Activity activity = this;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        this.getWindow().requestFeature(Window.FEATURE_PROGRESS);
        setContentView(R.layout.activity_gossip_mate);
        final WebView webView = (WebView) findViewById(R.id.webview);
        webView.getSettings().setJavaScriptEnabled(true);
        webView.setWebChromeClient(new WebChromeClient() {
            public void onProgressChanged(WebView view, int progress) {
                activity.setTitle("Loading");
                activity.setProgress(progress * 100);

                if (progress == 100)
                    activity.setTitle(R.string.app_name);
            }

        });
        webView.setWebViewClient(new WebViewClient() {
            @Override
            public void onReceivedError(WebView view, int errorCode,
                    String description, String failingUrl) {
                // Handle the error
            }

            @Override
            public boolean shouldOverrideUrlLoading(WebView view, String url) {
                view.loadUrl(url);
                return true;

清单文件

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.gossipmate.mobi"
android:versionCode="1"
android:versionName="1.0" >

<uses-sdk
    android:minSdkVersion="10"
    android:targetSdkVersion="15" />

<uses-permission android:name="android.permission.INTERNET" >
</uses-permission>

<application
    android:icon="@drawable/ic_launcher"
    android:label="@string/app_name"
    android:theme="@style/AppTheme" >
    <activity
        android:name=".GossipMate"
        android:label="@string/title_activity_gossip_mate" >
        <intent-filter>

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
</application>

以上是我使用的清单代码我相信我已经注册了活动

使用m更改M并启动新项目后，应用程序正在运行，没有任何问题。

Answer 1

检查Manifest文件中活动名称的拼写，错误。它应该是Gossipmate而不是GossipMate。

<强>更新

尝试将此行放入您的清单android:name="com.example.gossipmate.mobi.Gossipmate"而不是android:name=".GossipMate"

Answer 2

在AndroidManifest.xml.中，活动的名称为android:name=".GossipMate"，其中m的配偶为大写字母，活动中的位置为Gossipmate !!!

检查java.lang.RuntimeException: Unable to instantiate activity ComponentInfo

Webview android app forcecloses
