/**
 * 方法4：通过使用UsageStatsManager获取，此方法是ndroid5.0A之后提供的API
 * 必须：
 * 1. 此方法只在android5.0以上有效
 * 2. AndroidManifest中加入此权限<uses-permission xmlns:tools="http://schemas.android.com/tools" android:name="android.permission.PACKAGE_USAGE_STATS"
 * tools:ignore="ProtectedPermissions" />
 * 3. 打开手机设置，点击安全-高级，在有权查看使用情况的应用中，为这个App打上勾
 *
 * @param context     上下文参数
 * @param packageName 需要检查是否位于栈顶的App的包名
 * @return
