我正在尝试构建一个开发人员可以在自己的应用程序中使用的.jar库。我的库中有3个视图（活动），我希望开发人员能够在他们的应用程序中显示如下：
// Developer's activity
public class MainActivity extends Activity {
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
// This method returns an intent which calls
// an activity packaged in my .jar file
startActivity(EvelynsLibrary.showView(this));
}
}
主库类EvelynsLibrary有一个静态'showView'方法，它接受一个活动（获取上下文），根据上下文和我的.jar中捆绑的Activity创建一个intent，并返回一个Intent，开发人员可以使用startActivity进行演示。
不确定是否需要，但我还将外部活动添加到调用应用的AndroidManifest.xml文件中，如下所示：
<activity
android:name="com.evelyn.EvelynsActivity"
android:label="Evelyn"
android:configChanges="orientation|screenSize"
android:screenOrientation="fullSensor">
<intent-filter>
<action android:name="android.intent.action.MAIN"/>
<category android:name="android.intent.category.LAUNCHER"/>
</intent-filter>
</activity>
我收到以下错误：
java.lang.RuntimeException: Unable to start activity ComponentInfo{com.example.myapp/com.evelyn.EvelynsActivity}: android.content.res.Resources$NotFoundException: Resource ID #0x7f030002
这是我的整个错误（Logcat）输出：

问题：我哪里错了？如何实现这一点并允许开发人员调用我的.jars活动？
答案 0 :(得分：1)
你应该创建一个Android库项目而不是jar
