ionic cordova build android的时候报错
No resource identifier found for attribute 'appComponentFactory' in package 'android'
或者：error: resource android:attr/fontVariationSettings resource android:attr/ttcIndex not found.
解决方案如下：
在build.gradle 的allprojects里面加上
configurations.all {
resolutionStrategy.force 'com.android.support:support-v4:24.0.0'
}
