如何在 Android 中声明两个不同的应用程序 Manifest 或将它们合并为一个应用程序 class

Question

我已将两个包合并为一个：this and this 合并为一个。我面临的问题是我只能在 android 清单中声明一个应用程序。我有两个应用程序要声明：用于 Volley 的 AppController 和用于 Parse 包的 ParseApplication。

如何在AndroidManifest中只申报一个应用程序？我还是个新手，正在尝试通过合并一些我在网上找到的代码来练习我在网上阅读或观看的内容。

谢谢！

更新：这是 Appcontroller class：

Public class AppController extends Application {

public static final String TAG = AppController.class.getSimpleName();

private RequestQueue mRequestQueue;
private ImageLoader mImageLoader;
LruBitmapCache mLruBitmapCache;

private static AppController mInstance;

@Override
public void onCreate() {
    super.onCreate();
    mInstance = this;
}

public static synchronized AppController getInstance() {
    return mInstance;
}

public RequestQueue getRequestQueue() {
    if (mRequestQueue == null) {
        mRequestQueue = Volley.newRequestQueue(getApplicationContext());
    }

    return mRequestQueue;
}

public ImageLoader getImageLoader() {
    getRequestQueue();
    if (mImageLoader == null) {
        getLruBitmapCache();
        mImageLoader = new ImageLoader(this.mRequestQueue, mLruBitmapCache);
    }

    return this.mImageLoader;
}

public LruBitmapCache getLruBitmapCache() {
    if (mLruBitmapCache == null)
        mLruBitmapCache = new LruBitmapCache();
    return this.mLruBitmapCache;
}

public <T> void addToRequestQueue(Request<T> req, String tag) {
    req.setTag(TextUtils.isEmpty(tag) ? TAG : tag);
    getRequestQueue().add(req);
}

public <T> void addToRequestQueue(Request<T> req) {
    req.setTag(TAG);
    getRequestQueue().add(req);
}

public void cancelPendingRequests(Object tag) {
    if (mRequestQueue != null) {
        mRequestQueue.cancelAll(tag);
    }
}

}

public class ParseApplication extends Application {

@Override
public void onCreate() {
    super.onCreate();
    Parse.enableLocalDatastore(this);
    // Add your initialization code here
  Parse.initialize(this, "ui3OHYCLF4wlTNZcbkPhRkiEN4yiURuRZxYnXMSX", "J60b54ajmUuDk7wu94GmX3DpBbJOrv5IzSuRd5V2");

    ParseUser.enableAutomaticUser();
    ParseACL defaultACL = new ParseACL();

    // If you would like all objects to be private by default, remove this
    // line.
    defaultACL.setPublicReadAccess(true);

    ParseACL.setDefaultACL(defaultACL, true);
}

}

Answer 1

假设您只想要一个应用程序并且只想使用两个合并包中的每个活动和类，您可以添加 application 中的所有 activity 声明第二个包的标签到第一个包的 manifest 文件的 application 标签。

现在只使用第一个包的manifest文件，把应用名称和图标改成你喜欢的。

希望对您有所帮助，否则请更详细地解释您想要实现的目标。

Answer 2

我通过将 ParseApplication class 合并到 AppController class 并仅将 AppController 声明为 application 来修复它manifest。谢谢。
