我有这样做fb代码：

private void fbLike_optionA() {

    Bundle params1 = new Bundle();
    params1.putString("object", "http://samples.ogp.me/226075010839791");
    /* make the API call */
    new Request(Session.getActiveSession(), "/me/og.likes", params1,
            HttpMethod.POST, new Request.Callback() {
                public void onCompleted(Response response) {
                    /* handle the result */

                    String a = "1";
                }
            }).executeAsync();
}
由于假（？）url？

，

是错误

我屯并得到这个错误：

我建议你使用这个库（details here）：

dependencies {
    compile 'com.shamanland:facebook-like-button:0.1.8'
}

这个库实现了＆＃39; like＆＃39;使用基于facebook plugin的WebView和基于<iframe>的行动。

AsyncTask的这种方法引发了异常：

public final AsyncTask<Params, Progress, Result> executeOnExecutor(Executor exec, Params... params) {
    if (mStatus != Status.PENDING) {
        switch (mStatus) {
            case RUNNING:
                throw new IllegalStateException("Cannot execute task:"
                        + " the task is already running.");
            case FINISHED:
                throw new IllegalStateException("Cannot execute task:"
                        + " the task has already been executed "
                        + "(a task can be executed only once)");
        }
    }

    mStatus = Status.RUNNING;

    onPreExecute();

    mWorker.mParams = params;
    exec.execute(mFuture);

    return this;
}

所以这意味着你尝试执行已经运行的任务。
