Requirements check results for android:
Java JDK: installed .
Android SDK: installed
Android target: not installed
Android SDK not found. Make sure that it is installed. If it is not at the defau
lt location, set the ANDROID_HOME environment variable.
Gradle: not installed
Could not find gradle wrapper within Android SDK. Might need to update your Andr
oid SDK.
Looked here: D:\D_C\Androidsdk\tools\templates\gradle\wrapper
Error: Some of requirements check failed
解决方法：将下载好的放到D:\D_C\Androidsdk\下
To run dex in process, the Gradle daemon needs a larger heap.
It currently has approximately 910 MB.
For faster builds, increase the maximum heap size for the Gradle daemon to more
than 2048 MB.
To do this set org.gradle.jvmargs=-Xmx2048M in the project gradle.properties.
For more information see https://docs.gradle.org/current/userguide/build_environ

解决办法：
这个问题我也遇到了，荡了好多帖子找到的解决方法。原因是最新版dx.jar文件可能不兼容导致。
先关闭IDE，
找到自己SDK下build-tools文件夹，打开后会有不止一个版本的文件夹。
选择一个版本较低的文件夹打开->打开lib文件夹->复制当前dx.jar文件；
向上返回，打开版本最新（高）的文件夹->打开lib文件夹->用复制的dx.jar文件替换当前文件（不放心可以先备份一个留着）。

解决办法：platforms/android/build.gradle中添加：
compileSdkVersion 28
buildToolsVersion “28.0.0”
为什么要这样呢？
Android中出现Error:In (declare-styleable) FontFamilyFont, unable to find attribute android:font 解决办法，今天由于项目要用到 support-v4 包，所以就导入v4 包到项目中，可是导入之后就出现 Error:In FontFamilyFont, unable to find attribute android:font 这个错误，如下图：
然后就是上网各种搜，看大多数都是说 compileSdkVersion 和buildToolsVersion 的版本不对应，所以才会出现这种问题，但是按照这种提示修改之后，问题依旧还在，然后就想会不会是 compileSdkVersion 和buildToolsVersion 的版本太低了，就把这两个的版本改成最新的，果然就没有问题了，希望此文章可以帮到遇到同样问题的你。
