Question

我创建了一个项目并将平台切换到android，并更改包标识符。

我只是测试构建并运行但它出现在错误消息中。首先，

**CommandInvokationFailure: Failed to build apk.**
C:\Program Files\Java\jdk1.7.0_79\bin\java.exe -Xmx2048M -Dcom.android.sdkmanager.toolsdir="C:\Users\UserName\AppData\Local\Android\Sdk\tools" -Dfile.encoding=UTF8 -jar "E:\StudyProject\Unity\Editor\Data\PlaybackEngines\AndroidPlayer/Tools\sdktools.jar" -

和第二，

**UnityEditor.BuildPlayerWindow+BuildMethodException: Build failed with errors.**

我之前安装了Unity，但没有设置。

我不知道为什么会出现这种问题。

如果您了解它，请帮助我。
