Android 致命异常 ActivityNotFoundException

Question

首先，我使用的是 Eclipse IDE。我正在尝试制作一个应用程序商店。我不知道发生了什么，但它以前有效，现在我在 LogCat 中收到此错误。

主 Activity .java

package com.servetech.appstore;


import android.os.Bundle;
import android.app.Activity;
import android.content.Intent;
import android.view.View;
import android.widget.Button;

public class MainActivity extends Activity {


Button btn;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    btn = (Button) findViewById(R.id.button1);

    btn.setOnClickListener(
            new View.OnClickListener() {

                @Override
                public void onClick(View v) {
                    // TODO Auto-generated method stub
                    Intent myIntent = new Intent("com.example.appstore.GAMENAME");
                    startActivity(myIntent);
                }
            });

}



}

Android list :

<?xml version="1.0" encoding="utf-8"?>

package="com.servetech.appstore"
android:versionCode="1"

        android:label="@string/app_name" >
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

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

    <activity
        android:name=".GameName"
        android:label="@string/app_name" >
        <intent-filter>
            <action android:name="com.servetech.appstore.GAMENAME" />

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

</application>

PS:我注意到我启动 Activity 的方式与其他人略有不同。只是想让你知道我正在学习新波士顿教程。我希望这不是问题。如果需要，我可以发布 GameName 类。

编辑:已经解决了这个问题，所以不要浪费你的时间试图提供帮助:)

Answer 1

您尝试运行类 "com.example.appstore.GAMENAME 但在 list 中您得到了 packageName+.GameName。所以不是 Intent myIntent = new Intent("com.example.appstore.GAMENAME"); 试试 Intent myIntent = new Intent("com.servetech.appstore.GAMENAME");
