点击“使用Facebook登录”(简单的登录按钮)时出现此错误。
我拥有Google，并在此处阅读其他主题-但看不到任何与我的问题相符的内容。
我在下面添加Login.java类。
public class Login extends Activity {
/**
* Called when the activity is first created.
*/
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
FacebookSdk.sdkInitialize(getApplicationContext());
setContentView(R.layout.activity_login);
CallbackManager callbackManager = CallbackManager.Factory.create();
LoginButton loginButton = (LoginButton) findViewById(R.id.login_button);
loginButton.setReadPermissions("public_profile", "email", "user_friends");
// Other app specific specialization
loginButton.registerCallback(callbackManager, new FacebookCallback<LoginResult>() {
@Override
public void onSuccess(LoginResult loginResult) {
Log.i("Login", "Logged in: ");
Intent i = new Intent(Login.this, MainActivity.class);
startActivity(i);
}
@Override
public void onCancel() {
// App code
}
@Override
public void onError(FacebookException exception) {
// App code
Log.i("Error" , "Error");
}
});
}
}
