Question

我尝试为我的应用制作社交模块，类似于包装器，包含google +，Facebook和twitter集成模板。

我决定从Facebook开始，但我无法弄清我需要将两个模块的哪些数据放入Facebook API信息中心。

我有两个包名：

模块：com.example.denis.socialwrapper
app：com.example.denis.socialapp

我的模块项目只有一个班FacebookTemplate
我的应用项目有Activity和Fragment

当我编译项目并按下LoginButton时，它只显示progressBar。

这是我的FacebookTemplate类，位于模块中：

public class FacebookTemplate {
//template should has only one instance
private static FacebookTemplate facebookTemplate;

private String permissions;
private String requestFields;
private CallbackManager callbackManager; //fb callback
private LoginButton fbButton;
private FacebookCallback<LoginResult> callbackListener;
private GraphRequest.Callback graphAPIListener;

//========================================================================
//GET STATIC INSTANCE VIA DIFFERENT CONSTRUCTORS
//========================================================================

public static FacebookTemplate getInstance(){
    if(facebookTemplate==null){
        facebookTemplate = new FacebookTemplate();
        facebookTemplate.setPermissions("user_profile");
        facebookTemplate.setRequestFields("id,name");
        return facebookTemplate;
    }
    return facebookTemplate;
}

public FacebookTemplate() {
}

//you must invoke this method before debug
public void initFacebookIntegration(Context context){
    FacebookSdk.sdkInitialize(context);
}
//======================================================================
// CONFIGURING FACEBOOK INTEGRATION (FRAGMENT/ACTIVITY)
//======================================================================

public void configureFacebookUsingFragment(@NonNull Fragment fragment){
    callbackManager = CallbackManager.Factory.create();
    fbButton.setReadPermissions(permissions);
    fbButton.setFragment(fragment);
    // Callback registration
    fbButton.registerCallback(callbackManager, callbackListener);
}
public void configureFacebookUsingActivity(){
    callbackManager = CallbackManager.Factory.create();
    fbButton.setReadPermissions(permissions);
    // Callback registration
    fbButton.registerCallback(callbackManager, callbackListener);
}

//======================================================================
// GETTING RESULT OF onActivityResult()
//======================================================================

public void throwToOnActivityResult(int requestCode,int resultCode,Intent data){
    callbackManager.onActivityResult(requestCode, resultCode, data);
}

//======================================================================
// GETTERS AND SETTERS
//======================================================================
@NonNull
public CallbackManager getCallbackManager() {
    return callbackManager;
}

public LoginButton getFbButton() {
    return fbButton;
}

public void setPermissions(String permissions) {
    this.permissions = permissions;
}

public String getPermissions() {
    return permissions;
}

public String getRequestFields() {
    return requestFields;
}

public void setRequestFields(String requestFields) {
    this.requestFields = requestFields;
}

public void setFbButton(LoginButton fbButton) {
    this.fbButton = fbButton;
}

public void setCallbackListener(FacebookCallback<LoginResult> callbackListener) {
    this.callbackListener = callbackListener;
}

public void setGraphAPIListener(GraphRequest.Callback graphAPIListener) {
    this.graphAPIListener = graphAPIListener;
}
public interface GraphAPIListener extends GraphRequest.Callback{
    @Override
    void onCompleted(GraphResponse graphResponse);
}
public interface FacebookCallbackListener extends FacebookCallback<LoginResult>{
    @Override
    void onSuccess(LoginResult loginResult);

    @Override
    void onCancel();

    @Override
    void onError(FacebookException e);
}

}

在Application类中我初始化Facebook SDK，这里是代码：

public class App extends Application {

private static FacebookTemplate FBTemplate;

@Override
public void onCreate() {
    super.onCreate();
    initFacebook();
}

private void initFacebook(){
    FBTemplate = FacebookTemplate.getInstance();
    FBTemplate.initFacebookIntegration(this);
}
public static FacebookTemplate getFacebookTemplate(){
    return FBTemplate;
}

}

这是我的片段：

public class MainFragment extends Fragment {

@Bind(R.id.facebook_button)LoginButton fbButton;
private FacebookTemplate facebookTemplate;
private static MainFragment fragment;
public static MainFragment getInstance(){
    if(fragment==null){
        fragment = new MainFragment();
        return fragment;
    }
    return fragment;
}
@Nullable
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
    View v = inflater.inflate(R.layout.main_fragment,container,false);
    ButterKnife.bind(this, v);
    configureFacebookAPI(null,null);
    return v;
}
private void configureFacebookAPI(@Nullable String permissions,@Nullable String requestFields){
    facebookTemplate = App.getFacebookTemplate();
    facebookTemplate.setFbButton(fbButton);
    if(permissions!=null) facebookTemplate.setPermissions(permissions);
    if(requestFields!=null) facebookTemplate.setRequestFields(requestFields);
    facebookTemplate.configureFacebookUsingFragment(this);
    facebookTemplate.setCallbackListener(callbackListener);
    facebookTemplate.setGraphAPIListener(graphAPIListener);
}
@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    facebookTemplate.throwToOnActivityResult(requestCode, resultCode, data);
}

@Override
public void onDestroyView() {
    super.onDestroyView();
    ButterKnife.unbind(this);
}

FacebookTemplate.FacebookCallbackListener callbackListener = new FacebookTemplate.FacebookCallbackListener() {
    @Override
    public void onSuccess(LoginResult loginResult) {

    }

    @Override
    public void onCancel() {

    }

    @Override
    public void onError(FacebookException e) {

    }
};

FacebookTemplate.GraphAPIListener graphAPIListener = new FacebookTemplate.GraphAPIListener() {
    @Override
    public void onCompleted(GraphResponse graphResponse) {

    }
};

}

Answer 1

仅尝试com.example.denis。您只需要输入您的包裹名称。

Answer 2

java＆＃34;包＆＃34;没关系。重要的是 AndroidManifest 包。从那里仔细检查您的包裹。

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.mygreatapp.droid" > <----- THIS PACKAGE

........

</manifest>

Answer 3

我设置的权限不正确;修复解决了我的问题。
