Question

我尝试用greendroid做一个应用程序，但我遇到了问题，我不知道如何解决它... 在这个时候，我已经尝试了我在网上找到的所有东西，但没有解决我的问题......

如果有人知道什么是错的......

MainApplication.java：

package com.example.testtt;
import greendroid.app.GDApplication;
    public class MainApplication extends GDApplication {
        @Override
        public Class<?> getHomeActivityClass() {
            return MainApplication.class;
        }
    }
}

MainActivity.java：

package com.example.testtt;

import greendroid.app.GDActivity;
import android.os.Bundle;

public class MainActivity extends GDActivity {

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        //setContentView(R.layout.activity_main);
    }

}

和清单：

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

    <uses-sdk
        android:minSdkVersion="7"
        android:targetSdkVersion="15" />

    <application android:icon="@drawable/ic_launcher" android:label="@string/app_name"
         android:theme="@style/Theme.GreenDroid" android:name="com.example.testtt.MainApplication">
        <activity
            android:name="com.example.testtt.MainActivity"
            android:label="@string/title_activity_main" >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

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

</manifest>

我有这个错误：

Answer 1

在您的应用程序MainActivity.class中返回getHomeActivityClass()。

android.content.ActivityNotFoundException：无法找到显式活动类[greendroid]
