我已经创建了一个带有以下变量的Ionic 6.19.1应用程序。gradle文件和“ionic capacitor run android”命令可以完美运行，应用程序也可以完美运行：

ext {
    minSdkVersion = 26
    compileSdkVersion = 30
    targetSdkVersion = 30
    androidxActivityVersion = '1.2.0
    androidxAppCompatVersion = '1.2.0
    androidxCoordinatorLayoutVersion = '1.1.0
    androidxCoreVersion = '1.3.2
    androidxFragmentVersion = '1.3.0
    junitVersion = '4.13.1
    androidxJunitVersion = '1.1.2
    androidxEspressoCoreVersion = '3.3.0
    cordovaAndroidVersion = '7.0.0'
}

但如果我将compileSdkVersion = 30替换为compileSdkVersion = 26，则“ionic capacitor run android”命令会产生以下错误：
