添加 Scringo 库后的 Android 错误答案

【问题标题】：Android Errors after adding Scringo Library添加 Scringo 库后的 Android 错误
【发布时间】：2013-12-22 09:50:01
【问题描述】：

在我的项目中包含 Scringo 库后，实施快速入门说明：

private Scringo scringo;
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);
    Scringo.setAppId("<MY_SCRINGO_APP_ID>");
    scringo = new Scringo(this);
    scringo.init();
    scringo.addSidebar();


}

@Override
protected void onStart() {
    super.onStart();
    scringo.onStart();
}

@Override
protected void onStop() {
    super.onStop();
    scringo.onStop();
}

我合并 Manifest.xml 以获得权限并设置新按钮以打开 Scringo 菜单。运行应用程序后，单击按钮打开 Scringo 菜单时，出现错误：

请帮忙...

【问题讨论】：

标签： android android-library httpconnection

【解决方案1】：

仔细查看日志，你会发现你需要在你的AndroidManifest.xml中添加INTERNET权限：

<uses-permission android:name="android.permission.INTERNET" />

【讨论】：

这不是问题...我添加了互联网权限并仔细检查是否是问题所在。还有其他想法吗？
@MuliBachar 请将该清单部分复制粘贴到问题中。这是最可能的原因，如果权限名称中有一个拼写错误，它就不会起作用。

【解决方案2】：

当您将 Scringo 项目库设置为项目的依赖项并在 project.properties 中设置 manifestmerger.enabled=true 时，它会将您的清单与 Scringo 清单合并。在 Scringo 清单中，已经添加了 INTERNET 权限。如果合并中出现某种错误，您将在 Eclipse 控制台中看到它。

合并后的清单应该在您的 bin 文件夹中，看看那里是否合并正确以及那里是否存在 INTERNET 权限。

顺便说一句，有时“清理”项目会有所帮助；-)
