我点击"使用Facebook登录"(简单登录按钮)时收到此错误.
我有谷歌,并在这里阅读其他主题 - 但我看不到任何匹配我的问题.
我在下面添加了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 …当我运行我的Android应用程序,并单击批准给予权限时,它不会被重定向到MainActivity."登录"消息未显示在Catlog中.我已阅读Facebook开发人员指南,并将我的代码与Stack的不同主题进行了比较.我看不出我做错了什么.
