我已经构建了一个应用程序来插入记录但它在编译时出错请帮助我我的 jasonparser 类是

    public JSONParser() {}

            StringBuilder sb = new StringBuilder();
            String line = null;
            while ((line = reader.readLine()) != null) {
                sb.append(line + "\n");
            }
            is.close();
            json = sb.toString();
        } catch (Exception e) {

        }
        try {
            jObj = new JSONObject(json);
        } catch (JSONException e) {
            Log.e("JSON Parser", "Error parsing data " + e.toString());
        }
        return jObj;
    }
}

在导入库时出现错误导入 org.apache.http

请帮助我提前谢谢

加入 build.gradle 后它在调试时出错应用程序正在打开然后它不幸地给出错误应用程序关闭

请检查一下谢谢我的日志猫是

【问题讨论】：

标签： java android apache-httpcomponents

【解决方案1】：

您的目标是 MarshMallow 吗？请检查您的build.gradle 文件。如果它包含minSdkVersion=23，那么您还必须在构建文件中包含以下内容。

android {
    useLibrary 'org.apache.http.legacy'
}

Apache 库已被弃用，并已从 Android MarshMallow 的 Android SDK 中移除。在此处阅读更多信息：https://developer.android.com/about/versions/marshmallow/android-6.0-changes.html

【讨论】：

我现在这样做了新的错误请检查它我正在更新我的问题
这是一个新错误，与您的主要问题无关。如果您需要帮助，请打开一个新问题。至于新错误，请检查 MainActivity.java 文件中的第 36 行。您在这里使用 EditText，它会崩溃，因为您的布局中的视图不是 EditText，而是 TextView。

【解决方案2】：

在带有 Gradle 的 Android Studio 中使用“org.apache.http.client”时，我遇到了类似的问题。如果您使用的是最新的构建工具，即 SDK 23，则此库已被弃用。

要解决此问题，您可以通过另一种方式包含它，它仍应与最新的构建工具/SDK 一起使用：

dependencies {
    compile 'org.jbundle.util.osgi.wrapped:org.jbundle.util.osgi.wrapped.org.apache.http.client:4.1.2'
}

你也可以参考这个答案： Can't import org.apache.http.HttpResponse in Android Studio
