Question

我在离子应用程序中进行了功能更改，并在浏览器中通过离子服务进行了测试。一切都很顺利，继续进行离子构建。所以它让我失误了。

I:\myprojects\fizion>ionic package info 30

  id       │ 30
  status   │ FAILED
  platform │ android
  mode     │ debug
  started  │ Jul 30th, 2017 10:32:28

output:

ANDROID_HOME=/opt/android-sdk
JAVA_HOME=/usr/lib/jvm/java-8-oracle
Error: Could not find gradle wrapper within Android SDK. Might need to update your Android SDK.
Looked here: /opt/android-sdk/tools/templates/gradle/wrapper

我不确定其建议升级的Android SDK。矿井或离子云？好的，我尝试升级我的android studio SDK然后开始其他问题。然后我发出以下命令来传播对android的新变化。

cordova prepare android

我已经构建了.apk文件并在手机中启动了。它崩溃了，所以在模拟器中尝试并得到以下错误。

我一直在经历许多SO帖子并尝试过许多但没有成功的事情。我很高兴分享我的android studio配置截图。我确信这是由于android studio的升级，但在哪里破解它。

有人可以指导我，我被封锁了。

Answer 1

我的android工作室向我展示了以下帖子中提到的警告。所以我忽略了它。但这是罪魁祸首并解决了这个问题。

Android, IntelliJ Idea, changing module type

Android Studio的Ionic Build错误。
