Question

当我尝试 ionic build android 时，无法在 ubuntu 上编译我的应用程序

我的AndroidManifest.xml

<uses-sdk android:minSdkVersion="16" android:targetSdkVersion="19" />

我的项目.属性

target=android-19
android.library.reference.1=CordovaLib

我的错误:

使用https://www.thepolyglotdeveloper.com/2014/09/install-android-cordova-ionic-framework-ubuntu/安装 ionic 环境

已尝试删除平台并再次添加平台。

以前有人遇到过这个错误吗？

谢谢!

android.webkit.ClientCertRequest ，此类需要 API 级别 21 或更高级别。 android:targetSdkVersion和target应该是 21 或更高。 一种方法是安装 API 21 或更高版本。另一种方法是通过运行 ionic platforms add <a href="https://stackoverflow.com/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="1d7c73796f7274795d2e332b3329" rel="noreferrer noopener nofollow">[email protected]</a> 添加旧的 Android 平台。 。 现在命令ionic build android会起作用的。
