Question

我已将以下（http://loopj.com/android-async-http/）添加到我的/ libs文件夹中，并将其作为库放入模块设置中并勾选导出按钮。在实际文件中没有错误，因为它找不到类，当我导入com.loopj时，它会为我完成它并向我显示可用的选项。

但是，当我在手机上运行它时会出现以下错误：

和代码的提取（不完整的obv，因为URL是假的，但不应该影响任何东西）：

  private void requestAPIKeyFromOAuthToken(String token) {
        AsyncHttpClient client = new AsyncHttpClient();        // <-- this is line 118
        RequestParams params = new RequestParams("token", token);

        client.post("https://myrailsapp.com/api/v1/auth/verify", params, new AsyncHttpResponseHandler() {
            @Override
            public void onSuccess(String response) {
                Log.w("OAUTH", "Got API key from server: " + response);
                finish();
            }

            @Override
            public void onFailure(Throwable e) {
                Log.w("OAUTH", "Error getting API key");
                Toast.makeText(getApplicationContext(), R.string.connection_error_message, Toast.LENGTH_LONG).show();

                e.printStackTrace();
            }
        });
    }

有人知道这个问题的解决方案吗？

非常感谢，丹尼尔

在Android Studio中，您必须将jar添加到lib文件夹中，将依赖项添加到build.gradle文件中并从控制台调用gradlew clean。 gradlew位于项目目录中。

（Android）com.loopj.android.http.AsyncHttpClient没有Class Def Found错误
