Android facebook crash

Question

I setup the Facebook sdk in Eclipse and I am using Facebook sdk 4.18.

I already added Facebook.jar to build path, but also crashes.

    protected void onCreate(Bundle savedInstanceState){
        super.onCreate(savedInstanceState); 

        FacebookSdk.sdkInitialize(this); //Crash this line
    }

public void initFB(){
        Log.e("Facebook", "init facebook");
        LoginManager.getInstance().logInWithReadPermissions(this, Arrays.asList("public_profile"));

        Log.e("Facebook", "init facebook2");
        LoginManager.getInstance().registerCallback(callbackManager, new FacebookCallback<LoginResult>() {

            @Override
            public void onSuccess(LoginResult loginResult) {

                Log.d("FB", "access token got.");

                fbLoginCallBack(loginResult.getAccessToken().getToken());

//              accessToken = loginResult.getAccessToken();
            }

            @Override
            public void onCancel() {
                // App code
                Log.d("FB", "CANCEL");
            }

            @Override
            public void onError(FacebookException exception) {
                // App code
                Log.d("FB", exception.toString());
            }
        });
    }

Answer 1

@Manlok Wong I am also facing this problem, So the solution is like

FacebookSdk. sdkInitialize (this); It is not properly taking the class

So, try this FacebookSdk. sdkInitialize (Your Activity. this); FacebookSdk. sdkInitialize (Your Activity. this);

And in Application class, in **onCreate () ** Method

FacebookSdk. sdkInitialize (getApplicationContext ());

Answer 2

Try

FacebookSdk.sdkInitialize(getApplicationContext());

//or

FacebookAPI.getInstance().init(getApplicationContext());

Answer 3

Right Click on your project -> Build Path -> Configure Build Path -> Order and Export Tab.

Make sure that "Facebook.jar" is checked for Export.

Answer 4

In my case, our Android app was completly crashing (in Android 8 only) whenever a call to logInWithReadPermissions() was made:

/* This caused an immediate crash of the application - wrapping with 
   try/catch failed to "catch" any unhandled expection that may have been
   causing the crash */
LoginManager.getInstance().logInWithReadPermissions(this, PERMISSIONS);

It turns out that the inclusion of the android:screenOrientation attribute in our manifest's com.facebook.FacebookActivity activity was the cause of the crash:

<!-- Causes crash -->
<activity 
    android:name="com.facebook.FacebookActivity"
    android:label="@string/app_name"
    android:configChanges="keyboard|keyboardHidden|screenLayout|screenSize|orientation"
    android:screenOrientation="portrait" />

Updating the <acitivty/> as follows fixed the bug:

<!-- Resolved the crash -->
<activity 
    android:name="com.facebook.FacebookActivity"
    android:label="@string/app_name" />

As part of my investigation into the cause of this bug, I also updated the project's FacebookSDK dependancy from com.facebook.android:facebook-android-sdk:4.20.0 to the more recent com.facebook.android:facebook-android-sdk:5.0.0 .

Hope this helps someone!
