扩展类com.facebook.widget.LoginButton时出错

Question

我使用3.0文档中的步骤构建了Facebook集成。当我使用Eclispe将应用程序部署到手机时，它可以正常工作;但是，当我导出应用程序将其上传到商店并侧面加载apk时，它会失败，并显示以下错误。当我导出它时，SDK就在那里并加载了。关于我哪里出错的任何线索？

编辑：--------------------------------------------- -

以下是我的尝试：

1. 尝试清理我的项目和FacebookSDK大约50次。
2. 删除了FacebookSDK并重读了3次。

我已经尝试了所有可以在互联网上找到的东西，但无法弄清楚问题是什么。

Answer 1

FacebookSdk.sdkInitialize(getApplicationContext());

这在setContentView

之前

  setContentView(R.layout.activity_home);

Answer 2

如果您使用的是Facebook SDK 4.x，请注意包名称已更改。它现在是com.facebook.login.widget.LoginButton

Answer 3

我遇到了同样的错误，我刚刚清理了我的项目（facebook sdk和当前项目）并且已经解决了。

Answer 4

你必须在setContentView之前初始化facebook SDK，所以在setContentView正上方添加以下行

FacebookSdk.sdkInitialize(getApplicationContext());

Answer 5

将Facebook添加为模块后，您必须将其添加到Gradle中的依赖项中，将下一行添加到依赖项块中：

compile project(':facebook')

我希望它可以提供帮助。

Answer 6

我发现修复此问题的唯一方法是将整个SDK放入我的项目中。现在它有效。不是首选的解决方案，但它确实有效。

Answer 7

即使我试图在模拟器中运行它，我也有同样的错误。

我的问题更加相关，我将Facebook Sdk添加到构建路径，而不是在“属性”选项卡中添加项目。我从another stackoverflow answer

得到了答案

Answer 8

刚刚初始化FacebookSdk.sdkInitialize（getApplicationContext（））;在您的Application类中。因为Application类甚至在您的活动初始化之前就已初始化。

就像这样：

public class ApplicationController扩展Application {

@Override
public void onCreate() {
    super.onCreate();
    FacebookSdk.sdkInitialize(getApplicationContext());
}

}

Answer 9

一种解决方案是将Facebook SDK的路径添加到项目中的“project.properties”。

像：

android.library.reference.1=../libfacebook/facebook-android-sdk-3.0.1/facebook

Answer 10

我也有同样的错误，只是通过android-support-v4.jar与android-support-v13.jar关联解决问题。

Answer 11

以防万一..如果有人还需要它，只清理facebook项目，然后将其作为库添加回项目中。这解决了我的问题

Answer 12

我尝试以编程方式创建LoginButton的实例，以编程方式

itemsArray[n][name]

并将其添加到 LinearLayout

Item 2

这是我的布局xml的一瞥

LoginButton loginButton = new LoginButton(this);

这是@Lalit Kumar's answer建议的编辑之后 如果我错过任何东西，请告诉我。

Answer 13

如果您将facebook库添加到Properties-＆gt; Android的应用程序中，则应删除facebooksdk路径/ bin / facebook.jar中的facebook.jar。在eclipse中链接时会导致错误。然后你清理你的Facebook sdk和你的应用程序。我希望能正常工作。
