史铁生的《我与地坛》是我很喜欢的一篇文章,每次我感到低谷和失望时,就会拿出这篇文章来读一读,积蓄力量,奋力前行!

我在好几篇小说中都提到过一座废弃的古园,实际就是地坛。许多年前旅游业还没有开展,园子荒芜冷落得如同一片野地,很少被人记起。

地坛离我家很近。或者说我家离地坛很近。总之,只好认为这是缘分。地坛在我出生前四百多年就坐落在那儿了,而自从我的祖母年轻时带着我父亲来到北京,就一直住在离它不远的地方——五十多年间搬过几次家,可搬来搬去总是在它周围,而且是越搬离它越近了。我常觉得这中间有着宿命的味道:仿佛这古园就是为了等我,而历尽沧桑在那儿等待了四百多年。

它等待我出生,然后又等待我活到最狂妄的年龄上忽地残废了双腿。四百多年里,它剥蚀了古殿檐头浮夸的琉璃,淡褪了门壁上炫耀的朱红,坍圮了一段段高墙又散落了玉砌雕栏,祭坛四周的老柏树愈见苍幽,到处的野草荒藤也都茂盛得自在坦荡。这时候想必我是该来了。十五年前的一个下午,我摇着轮椅进入园中,它为一个失魂落魄的人把一切都准备好了。那时,太阳循着亘古不变的路途正越来越大,也越红。在满园弥漫的沉静光芒中,一个人更容易看到时间,并看见自己的身影。

自从那个下午我无意中进了这园子,就再没长久地离开过它。我一下子就理解了它的意图。正如我在一篇小说中所说的:“在人口密聚的城市里,有这样一个宁静的去处,像是上帝的苦心安排。”

两条腿残废后的最初几年,我找不到工作,找不到去路,忽然间几乎什么都找不到了,我就摇了轮椅总是到它那儿去,仅为着那儿是可以逃避一个世界的另一个世界。我在那篇小说中写道:“没处可去我便一天到晚耗在这园子里。跟上班下班一样,别人去上班我就摇了轮椅到这儿来。园子无人看管,上下班时间有些抄近路的人们从园中穿过,园子里活跃一阵,过后便沉寂下来。”“园墙在金晃晃的空气中斜切下一溜荫凉,我把轮椅开进去,把椅背放倒,坐着或是躺着,看书或者想事,撅一杈树枝左右拍打,驱赶那些和我一样不明白为什么要来这世上的小昆虫。”“蜂儿如一朵小雾稳稳地停在半空;蚂蚁摇头晃脑捋着触须,猛然间想透了什么,转身疾行而去;瓢虫爬得不耐烦了,累了祈祷一回便支开翅膀,忽悠一下升空了;树干上留着一只蝉蜕,寂寞如一间空屋;露水在草叶上滚动,聚集,压弯了草叶轰然坠地摔开万道金光。”“满园子都是草木竞相生长弄出的响动,窸窸窣窣片刻不息。”这都是真实的记录,园子荒芜但并不衰败。

除去几座殿堂我无法进去,除去那座祭坛我不能上去而只能从各个角度张望它,地坛的每一棵树下我都去过,差不多它的每一米草地上都有过我的车轮印。无论是什么季节,什么天气,什么时间,我都在这园子里呆过。有时候呆一会儿就回家,有时候就呆到满地上都亮起月光。记不清都是在它的哪些角落里了,我一连几小时专心致志地想关于死的事,也以同样的耐心和方式想过我为什么要出生。这样想了好几年,最后事情终于弄明白了:一个人,出生了,这就不再是一个可以辩论的问题,而只是上帝交给他的一个事实;上帝在交给我们这件事实的时候,已经顺便保证了它的结果,所以死是一件不必急于求成的事,死是一个必然会降临的节日。这样想过之后我安心多了,眼前的一切不再那么可怕。比如你起早熬夜准备考试的时候,忽然想起有一个长长的假期在前面等待你,你会不会觉得轻松一点?并且庆幸并且感激这样的安排?

剩下的就是怎样活的问题了,这却不是在某一个瞬间就能完全想透的、不是一次性能够解决的事,怕是活多久就要想它多久了,就像是伴你终生的魔鬼或恋人。所以,十五年了,我还是总得到那古园里去,去它的老树下或荒草边或颓墙旁,去默坐,去呆想,去推开耳边的嘈杂理一理纷乱的思绪,去窥看自己的心魂。十五年中,这古园的形体被不能理解它的人肆意雕琢,幸好有些东西是任谁也不能改变它的。譬如祭坛石门中的落日,寂静的光辉平铺的一刻,地上的每一个坎坷都被映照得灿烂;譬如在园中最为落寞的时间,一群雨燕便出来高歌,把天地都叫喊得苍凉;譬如冬天雪地上孩子的脚印,总让人猜想他们是谁,曾在哪儿做过些什么、然后又都到哪儿去了;譬如那些苍黑的古柏,你忧郁的时候它们镇静地站在那儿,你欣喜的时候它们依然镇静地站在那儿,它们没日没夜地站在那儿,从你没有出生一直站到这个世界上又没了你的时候;譬如暴雨骤临园中,激起一阵阵灼烈而清纯的草木和泥土的气味,让人想起无数个夏天的事件;譬如秋风忽至,再有一场早霜,落叶或飘摇歌舞或坦然安卧,满园中播散着熨帖而微苦的味道。味道是最说不清楚的,味道不能写只能闻,要你身临其境去闻才能明了。味道甚至是难于记忆的,只有你又闻到它你才能记起它的全部情感和意蕴。所以我常常要到那园子里去。

be stored compressed in the .apk. An empty string means to not
compress any files at all.
--debug-mode
inserts android:debuggable="true" in to the application node of the
manifest, making the application debuggable even on production devices.
--include-meta-data
when used with "dump badging" also includes meta-data tags.
--pseudo-localize
generate resources for pseudo-locales (en-XA and ar-XB).
--min-sdk-version
inserts android:minSdkVersion in to manifest. If the version is 7 or
higher, the default encoding for resources will be in UTF-8.
--target-sdk-version
inserts android:targetSdkVersion in to manifest.
--max-res-version
ignores versioned resource directories above the given value.
--values
when used with "dump resources" also includes resource values.
--version-code
inserts android:versionCode in to manifest.
--version-name
inserts android:versionName in to manifest.
--replace-version
If --version-code and/or --version-name are specified, these
values will replace any value already in the manifest. By
default, nothing is changed if the manifest already defines
these attributes.
--custom-package
generates R.java into a different package.
--extra-packages
generate R.java for libraries. Separate libraries with ':'.
--generate-dependencies
generate dependency files in the same directories for R.java and resource package
--auto-add-overlay
Automatically add resources that are only in overlays.
--preferred-density
Specifies a preference for a particular density. Resources that do not
match this density and have variants that are a closer match are removed.
--split
Builds a separate split APK for the configurations listed. This can
be loaded alongside the base APK at runtime.
--feature-of
Builds a split APK that is a feature of the apk specified here. Resources
in the base APK can be referenced from the the feature APK.
--feature-after
An app can have multiple Feature Split APKs which must be totally ordered.
If --feature-of is specified, this flag specifies which Feature Split APK
comes before this one. The first Feature Split APK should not define
anything here.
--rename-manifest-package
Rewrite the manifest so that its package name is the package name
given here. Relative class names (for example .Foo) will be
changed to absolute names with the old package so that the code
does not need to change.
--rename-instrumentation-target-package
Rewrite the manifest so that all of its instrumentation
components target the given package. Useful when used in
conjunction with --rename-manifest-package to fix tests against
a package that has been renamed.
--product
Specifies which variant to choose for strings that have
product variants
--utf16
changes default encoding for resources to UTF-16. Only useful when API
level is set to 7 or higher where the default encoding is UTF-8.
--non-constant-id
Make the resources ID non constant. This is required to make an R java class
that does not contain the final value but is used to make reusable compiled
libraries that need to access resources.
--shared-lib
Make a shared library resource package that can be loaded by an application
at runtime to access the libraries resources. Implies --non-constant-id.
--app-as-shared-lib
Make an app resource package that also can be loaded as shared library at runtime.
Implies --non-constant-id.
--error-on-failed-insert
Forces aapt to return an error if it fails to insert values into the manifest
with --debug-mode, --min-sdk-version, --target-sdk-version --version-code
and --version-name.
Insertion typically fails if the manifest already defines the attribute.
--error-on-missing-config-entry
Forces aapt to return an error if it fails to find an entry for a configuration.
--output-text-symbols
Generates a text file containing the resource symbols of the R class in the
specified folder.

ADB(Android Debug Bridge) 工具是Android开发中使用很频繁也是非常重要的一个工具,用于手机与电脑的通信。

安装 ADB 工具:

在计算机上安装 Android SDK 或者仅安装 ADB 工具。从 Android 官方网站或者其他可信赖的来源获取它们。

如果你使用 macOS 或 Linux,你可以通过终端使用系统包管理器或 Homebrew 安装 ADB。 如果你使用 Windows,你可以下载 Android Studio ,它包含了 ADB 工具。

连接 Android 设备:

使用 USB 线将 Android 设备连接到计算机上。 在 Android 设备上打开开发者选项。这通常需要在设备设置中多次点击“关于手机” -> “版本号”或者类似的选项。一旦开启,返回设置菜单并找到“开发者选项”。

在“开发者选项”中,启用“USB 调试”。

adb shell pm list packages adb shell pm list packages -s //系统应用 adb shell pm list packages -3 //第三方应用 adb shell pm list packages | grep qq //过滤查找qq应用

卸载普通应用程序

卸载应用程序:

1
adb uninstall package_name

将 package_name 替换为你想要卸载的应用程序的包名。你可以通过之前提到的 adb shell pm list packages 命令来获取应用程序的包名列表。

示例:

假设你想卸载名为 “com.example.app” 的应用程序,命令将如下所示:

1
adb uninstall com.example.app

确认卸载:

执行命令后,ADB 会尝试卸载该应用程序。等待一段时间,命令提示符/终端会显示成功或失败的信息。 这个指令卸载系统自带应用可以能会遇到 Failure [DELETE_FAILED_INTERNAL_ERROR] 错误提示

卸载系统自带应用程序

清除应用程序数据:

在卸载应用之前,尝试先清除该应用的数据。使用以下命令:

1
adb shell pm clear package_name

将 package_name 替换为应用程序的包名。

强制停止应用程序:

如果应用程序正在运行,尝试通过 ADB 强制停止应用程序再进行卸载:

1
adb shell am force-stop package_name

将 package_name 替换为应用程序的包名。

确保设备有足够的存储空间来完成卸载操作。有时设备存储空间不足可能会导致卸载失败。

使用 ADB shell 运行命令:

adb shell

pm uninstall -k –user 0 package_name

安装 APK 文件

将要安装的 APK 文件复制到计算机上,并记住它的路径,使用以下命令安装 APK 文件到设备:

1
adb install /path/to/your/app.apk

Hi, everybody. This Sunday is Father’s Day, and so I wanted to take a moment to talk about the most important job many of us will ever have – and that’s being a dad.

大家好。本周日是父亲节,所以我想花点时间谈谈我们很多人一生最重要的一项工作——做一名父亲。

Today we’re blessed to live in a world where technology allows us to connect instantly with just about anyone on the planet. But no matter how advanced we get, there will never be a substitute for the love and support and, most importantly, the presence of a parent in a child’s life. And in many ways, that’s uniquely true for fathers.

如今,我们有幸生活在一个科技随时都能与全球任何人保持联系的世界里。然而,无论科技多么先进,都永远无法代替关爱和支持,特别是无法代替父母陪伴对于孩子生活的意义。就很多方面而言,对于身为人父者尤其如此。

I never really knew my own father. I was raised by a single mom and two wonderful grandparents who made incredible sacrifices for me. And there are single parents all across the country who do a heroic job raising terrific kids. But I still wish I had a dad who was not only around, but involved; another role model to teach me what my mom did her best to instill – values like hard work and integrity; responsibility and delayed gratification – all the things that give a child the foundation to envision a brighter future for themselves.

我对生身父亲知之甚少,而是由寡母和外祖父母抚养成人,她们为此做出了巨大的牺牲。全国各地也有许多这样的单身父母,他们勇敢面对,养育儿女。然而,我还是情愿父亲在我身边,并参与我的成长。(我希望他)能成为另一个角色,教会我许多(后来不得已)由母亲尽力传授的价值观念。比如,勤奋、正直、责任感和不急于享乐等等,这一切都为他的孩子赢得一个灿烂的未来奠定了基础。

That’ s why I try every day to be for Michelle and my girls what my father was not for my mother and me. And I’ve met plenty of other people – dads and uncles and men without a family connection –who are trying to break the cycle and give more of our young people a strong male role model.

这就是为什么我每天都会为米歇尔和女儿们做点事情,这正是先父没来得及为他的妻儿所做的。我也碰到过许多父亲、叔伯和其他没有完整家庭的男人,他们正努力打破这种怪圈,为年轻人树立一个男子汉的榜样。

Being a good parent – whether you’re gay or straight; a foster parent or a grandparent – isn’t easy. It demands your constant attention, frequent sacrifice, and a healthy dose of patience. And nobody’s perfect. To this day, I’m still figuring out how to be a better husband to my wife and father to my kids.

不管你是同性恋、异性恋,是养父母还是祖父母,做个好父母都不容易。要持续用心,不断付出,并且有一种健康的心态。没有人能十全十美,时至今日,我还在努力做个妻子的好丈夫和女儿们的好父亲。

And I want to do what I can as President to encourage marriage and strong families. We should reform our child support laws to get more men working and engaged with their children. And my Administration will continue to work with the faith and other community organizations, as well as businesses, on a campaign to encourage strong parenting and fatherhood.

同时,作为国家总统,我尽量鼓励婚姻和强有力的家庭维系。我们应该改革儿童抚养法律,让更多人有工作,并参与亲子互动。政府也将秉承这种信念,与社区组织、企业一道,踏上一次倡导可靠教养和父爱的征程。

Because if there’s one thing I’ve learned along the way, it’s that all our personal successes shine a little less brightly if we fail at family. That’s what matters most. When I look back on my life, I won’t be thinking about any particular legislation I passed or policy I promoted. I’ll be thinking about Michelle, and the journey we’ve been on together. I’ll be thinking about Sasha’s dance recitals and Malia’s tennis matches –about the conversations we’ve had and the quiet moments we’ve shared. I’ll be thinking about whether I did right by them, and whether they knew, every day, just how much they were loved.

因为一路走来我明白了一件事:如果家庭失败,即使个人事业再成功都将美中不足。(经营家庭)这事最重要。当我回顾人生,我不会去想(当总统时)通过了哪个特别法规、推动实施了哪项政策,我会想到和米歇尔一起走过的人生历程。我会想到萨拉的舞蹈演出和玛丽亚的网球比赛,想到我们的对话和共同拥有的静谧时光。我会想我做得对不对,我会想她们是否明白,每天我是多么疼爱她们。

That’s what I think being a father is all about. And if we can do our best to be a source of comfort and encouragement to our kids; if we can show them unconditional love and help them grow into the people they were meant to be; then we will have succeeded.

这就是我觉得一位为人父者所要关心的。如果我们竭尽所能去宽慰和鼓励孩子,给予他们无条件的爱并帮助他们做成自己想做的人,那么我们就成功了。

Happy Father’s Day to all the dads out there, and have a great weekend.

祝父亲们节日快乐,周末愉快!
