我使用Processing开发了基于物理的（Box2d）Android游戏，我想为它添加分数分享选项，以便用户可以在游戏后的Facebook时间线上分享他/她的最佳分数。我在eclipse中设置了Facebook SDK。我通过互联网搜索并找到了这个解决方案：
public class FacebookConnector {
private static final String APP_ID = "*************";
private Facebook facebook;
private AsyncFacebookRunner mAsyncRunner;
String FILENAME = "AndroidSSO_data";
SharedPreferences mPrefs;
public FacebookConnector() {
facebook = new Facebook(APP_ID);
mAsyncRunner = new AsyncFacebookRunner(facebook);
}
public void loginToFacebook() {
mPrefs = getPreferences(MODE_PRIVATE);
String access_token = mPrefs.getString("access_token", null);
long expires = mPrefs.getLong("access_expires", 0);
if (access_token != null) {
facebook.setAccessToken(access_token);
}
if (expires != 0) {
facebook.setAccessExpires(expires);
}
if (!facebook.isSessionValid()) {
facebook.authorize(LocalPakistaniGames.this,
new String[] { "email",
"publish_stream" }, new DialogListener() {
public void onCancel() {
// Function to handle cancel event
}
public void onComplete(Bundle values) {
// Function to handle complete event
// Edit Preferences and update facebook acess_token
SharedPreferences.Editor editor = mPrefs.edit();
editor.putString("access_token",
facebook.getAccessToken());
editor.putLong("access_expires",
facebook.getAccessExpires());
editor.commit();
}
public void onError(DialogError error) {
// Function to handle error
}
public void onFacebookError(FacebookError fberror) {
// Function to handle Facebook errors
}
});
}
}
public void logoutFromFacebook() {
mAsyncRunner.logout(LocalPakistaniGames.this,
new RequestListener() {
@Override
public void onComplete(String response, Object state) {
Log.d("Logout from Facebook", response);
if (Boolean.parseBoolean(response) == true) {
// User successfully Logged out
}
}
@Override
public void onIOException(IOException e, Object state) {
}
@Override
public void onFileNotFoundException(FileNotFoundException e,
Object state) {
}
@Override
public void onMalformedURLException(MalformedURLException e,
Object state) {
}
@Override
public void onFacebookError(FacebookError e, Object state) {
}
});
}
public void getProfileInformation() {
mAsyncRunner.request("me", new RequestListener() {
public void onComplete(String response, Object state) {
Log.d("Profile", response);
String json = response;
try {
JSONObject profile = new JSONObject(json);
// getting name of the user
final String name = profile.getString("name");
// getting email of the user
final String email = profile.getString("email");
runOnUiThread(new Runnable() {
@Override
public void run() {
Toast.makeText(getApplicationContext(),
"Name: " + name + "\nEmail: " + email,
Toast.LENGTH_LONG).show();
}
});
} catch (JSONException e) {
e.printStackTrace();
}
}
public void onIOException1(IOException e, Object state) {
}
public void onFileNotFoundException1(FileNotFoundException e,
Object state) {
}
public void onMalformedURLException1(MalformedURLException e,
Object state) {
}
@Override
public void onFacebookError(FacebookError e, Object state) {
}
@Override
public void onIOException(IOException e, Object state) {
// TODO Auto-generated method stub
}
@Override
public void onFileNotFoundException(FileNotFoundException e,
Object state) {
// TODO Auto-generated method stub
}
@Override
public void onMalformedURLException(MalformedURLException e,
Object state) {
// TODO Auto-generated method stub
}
});
}
public void postToWall(int level, int score) {
// post on user's wall.
String msg = "I just made new best score in Level " + level
+ ". My new Best Score is " + score + ". Beat my score!";
final Bundle parameters = new Bundle();
parameters.putString("description", msg);
parameters.putString("picture", "http://i57.tinypic.com/fui2o.png");
parameters.putString("link",
"https://www.facebook.com/LocalPakistaniGamesAndroid");
parameters.putString("name", "Local Pakistani Games");
parameters.putString("caption",
"Share this. Be a part of preserving Pakistani culture.");
LocalPakistaniGames.this.runOnUiThread(new Runnable() {
public void run() {
facebook.dialog(LocalPakistaniGames.this, "feed",
parameters, new DialogListener() {
@Override
public void onComplete(Bundle values) {
// TODO Auto-generated method stub
if (values != null) {
Toast.makeText(LocalPakistaniGames.this,
"Shared successfully on your timeline!",
Toast.LENGTH_SHORT).show();
} else {
Toast.makeText(
LocalPakistaniGames.this,
"Share cancelled!",
Toast.LENGTH_SHORT).show();
}
}
@Override
public void onFacebookError(FacebookError e) {
// TODO Auto-generated method stub
Toast.makeText(LocalPakistaniGames.this,
"Facebook Error!",
Toast.LENGTH_SHORT)
.show();
}
@Override
public void onError(DialogError e) {
// TODO Auto-generated method stub
Toast.makeText(LocalPakistaniGames.this,
"Error!", Toast.LENGTH_SHORT)
.show();
}
@Override
public void onCancel() {
// TODO Auto-generated method stub
Toast.makeText(LocalPakistaniGames.this,
"Share cancelled!",
Toast.LENGTH_SHORT).show();
}
});
}
});
}
}
它工作正常，并提供一个预先填充的对话框，用户可以在其中共享或关闭对话框。我已经检查过，它在Facebook时间线上正确分享。但问题是它没有在设备上安装Facebook应用程序。它在我的设备上使用chrome登录Facebook。 有没有办法强迫它使用Facebook应用程序的Android而不是去Chrome（或任何其他浏览器）??

使用Facebook SDK存在许多问题，但我会直接解决您的问题。
您正在使用＆＃34; Feed＆＃34;对话框分享。这是一个Web对话框，这就是它弹出WebView（而不是实际的浏览器应用程序）的原因。您也不会将任何会话或访问令牌传递给Feed对话框，这就是用户需要先登录才能共享的原因。
如果您想使用Facebook应用分享，我建议您使用此文档：https://developers.facebook.com/docs/android/share
如果您想正确使用Facebook SDK（而不是旧的弃用版），请从此处开始：https://developers.facebook.com/docs/android/getting-started/

Here是您问题的解决方案。如果你想在Facebook墙上制作自动出版物，你必须使用图形API。
此外，您要做的第一件事是使用Facebook登录，之后，您必须再次请求权限。
如果您使用LoginManager：
LoginManager.getInstance().logInWithPublishPermissions(this, Arrays.asList("publish_actions"));
此代码行为您的应用提供了代表用户制作出版物的权限
