Question

我尝试使用Facebook登录按钮构建一个简单的应用程序，我使用了教程，应用程序启动，Facebook登录按钮就在那里，但是当我按下它时，应用程序“退出”（在任务切换器中仍然可见））。

我尝试使用

compile 'com.facebook.android:facebook-android-sdk:4.6.0'

和

compile 'com.facebook.android:facebook-android-sdk:4.11.0'

。

日志没有说任何特殊内容：

最后2个条目（触摸事件：ACTION_DOWN和ACTION_UP）是按下登录按钮的日志。之后没有日志条目。

活动：

 public class LoginActivity extends AppCompatActivity {

 public static final String FLRT = "FLRT";

     private LoginButton loginButton;

     public CallbackManager callbackManager;

     @Override
     protected void onCreate(Bundle savedInstanceState) {
         super.onCreate(savedInstanceState);
         Log.d(FLRT, "onCreate");

         facebookSDKInitialize();

         setContentView(R.layout.activity_login);

         loginButton = (LoginButton) findViewById(R.id.login_button);
         loginButton.setReadPermissions("public_profile", "user_friends","user_birthday","user_about_me","email");
         getLoginDetails(loginButton);

     }

     @Override
     public void onBackPressed() {
         LoginActivity.this.finish();
         super.onBackPressed();
     }

     protected void facebookSDKInitialize() {
         Log.d(FLRT, "facebookSDKInitialize");

         FacebookSdk.sdkInitialize(LoginActivity.this);
         AppEventsLogger.activateApp(this);
         callbackManager = CallbackManager.Factory.create();
     }

     protected void getLoginDetails(LoginButton login_button){
         Log.d(FLRT, "getLoginDetails");

         // Callback registration
         login_button.registerCallback(callbackManager, new FacebookCallback<LoginResult>() {
             @Override
             public void onSuccess(LoginResult login_result) { 

                 Log.d(FLRT, "Facebook Login: Successful!");
             }

             @Override
             public void onCancel() {
                 // code for cancellation

                 Log.d(FLRT, "Facebook Login: Canceled!");
             }

             @Override
             public void onError(FacebookException exception) {
                 //  code to handle error

                 Log.d(FLRT, "Facebook Login: Error: " + exception.toString());
             }
         });
     }

     @Override
     protected void onActivityResult(int requestCode, int resultCode, Intent data) {
         super.onActivityResult(requestCode, resultCode, data);
         Log.d(FLRT, "onActivityResult");

         callbackManager.onActivityResult(requestCode, resultCode, data);
         Log.e("data",data.toString());
     }
}

哪里失败了？

谢谢！

您是否已将应用ID添加到AndroidManifest.xml

<meta-data
            android:name="com.facebook.sdk.ApplicationId"
            android:value="@string/facebook_app_id" />

Android - Facebook SDK registerCallback永远不会被调用？
