判斷Android 系統是MIUI 的，魅族的Flyme ，還是原生的?

// 檢測MIUI
import java.io.IOException;

public final class MIUIUtils {

	private static final String KEY_MIUI_VERSION_CODE = "ro.miui.ui.version.code";
	private static final String KEY_MIUI_VERSION_NAME = "ro.miui.ui.version.name";
	private static final String KEY_MIUI_INTERNAL_STORAGE = "ro.miui.internal.storage";

	public static boolean isMIUI() {
		try {
			final BuildProperties prop = BuildProperties.newInstance();
			return prop.getProperty(KEY_MIUI_VERSION_CODE, null) != null
					|| prop.getProperty(KEY_MIUI_VERSION_NAME, null) != null
					|| prop.getProperty(KEY_MIUI_INTERNAL_STORAGE, null) != null;
		} catch (final IOException e) {
			return false;
		}
	}
}

// 檢測Flyme
import android.os.Build;

import java.lang.reflect.Method;

public final class FlymeUtils {

	public static boolean isFlyme() {
		try {
			// Invoke Build.hasSmartBar()
			final Method method = Build.class.getMethod("hasSmartBar");
			return method != null;
		} catch (final Exception e) {
			return false;
		}
	}

}
