我正在使用 Android facebook SDK 在 facebook 墙上发帖。我使用以下代码进行墙贴,但每次都出现异常android.os.NetworkOnMainThreadException
public void postToWall(String message) {
Bundle parameters = new Bundle();
parameters.putString("message", message);
parameters.putString("description", "topic share");
try {
facebook.request("me");//Error here
String response = facebook.request("me/feed", parameters, "POST");
Log.d("Tests", "got response: " + response);
if (response == null || response.equals("")
|| response.equals("false")) {
showToast("Blank response.");
} else {
showToast("Message posted to your facebook wall!");
}
finish();
} catch (Exception e) {
showToast("Failed to post to wall!");
e.printStackTrace();
finish();
}
}
