Android模拟器支持运行ARM应用，Android 11系统映像可直接将ARM指令转换成x86指令

随着 Android 11 开发者预览版的发布，我们同时也推出了 Android 11 系统映像。新的系统映像在执行 ARM 二进制文件方面取得了显著的性能提升。此前，依赖 ARM 库且无法构建 x86 版本应用的开发者只能使用完整的 ARM 模拟系统映像 (其速度远低于在 x86 设备上运行 x86 系统映像) 或者实体机。Android 11 系统映像能够在不影响整个系统的前提下，直接将 ARM 指令转换成 x86 指令。开发者无需搭建高负载的 ARM 环境即可执行 ARM 二进制文件并进行测试。

gradle cache目录(.gradle)剖析

gradle下载后会对文件路径进行修饰，本文给出反向解析，把文件路径修改为原始路径的办法。

之所以研究这个，本来的目的是为了让Gradle支持离线编译，但是由于Gradle目录组织的缺陷，如.gradle/caches/modules-2/metadata-2.23(metadata-xx跟使用的gradle版本有关)目录下module-artifacts.bin等bin文件中存的是本机的绝对路径，导致就算将.gradle拷贝给另一台机器，还是需要联网验证。

将gradle的jcenter重定向的方法见我的另一篇文章：[android]gradle下载加速 - 知乎专栏，例如阿里云的jcenter是Index of /repositories/jcenter

我在内网中搭建了jcenter仓库。然而我不想搭建一个大而全的jcenter的仓库，搭建大而全的仓库可以使用nexus来搭建，阿里云也是那么搭的，由于公司的网络需要上网认证，时不时会断一下，所以我的做法是通过利用.gradle目录来创建jcenter仓库。

下面先介绍.gradle目录的组织。

1 .gradle顶级目录

目录| 功能
caches | gradle缓存目录
daemon | daemon日志目录
native | gradle平台相关目录
wrapper | gradle-wrapper下载目录

2 caches目录

目录 | 功能
2.14.1 | gradle程序的脚本（gradle程序版本）
3.2.1 | gradle程序的脚本（gradle程序版本）
jars-1 | ?
jars-2 | ?
modules-2 | 下载缓存目录

2.1 caches/modules-2目录

目录 | 功能
files-2.1 | gradle下载的jar/aar目录
metadata-2.16 | gradle-2.14.1的描述文件？
metadata-2.23 | gradle-3.2.1的描述文件？

2.1.1 files-2.1的目录组织（jar/aar都下载到这里）

${org}/${package}/${version}/${shanum1}/${package-version}.pom 
${org}/${package}/${version}/${shanum2}/${package-version}.jar

1 2	${org}/${package}/${version}/${shanum1}/${package-version}.pom ${org}/${package}/${version}/${shanum2}/${package-version}.jar

例如：

#jcenter上jar的路径
https://jcenter.bintray.com/com/android/tools/lint/lint-api/25.1.3/lint-api-25.1.3.jar
#对应的缓存目录为
.gradle/caches/modules-2/files-2.1/com.android.tools.lint/lint-api/25.1.3/${shasum1}/lint-api-25.1.3.jar

#看下这个目录下有什么？
~ find .gradle/caches/modules-2/files-2.1/com.android.tools.lint/lint-api/25.1.3/ -type f
#除了jar包还有pom，用于描述jar。
.gradle/caches/modules-2/files-2.1/com.android.tools.lint/lint-api/25.1.3/14c6a94811fb8114a61b8f3ab29214f9466b5c59/lint-api-25.1.3.jar
.gradle/caches/modules-2/files-2.1/com.android.tools.lint/lint-api/25.1.3/c4844e26d84dd1f450f90d89d7e2d2d09f52760/lint-api-25.1.3.pom

#看下jar的shasum
~ shasum .gradle/caches/modules-2/files-2.1/com.android.tools.lint/lint-api/25.1.3/14c6a94811fb8114a61b8f3ab29214f9466b5c59/lint-api-25.1.3.jar

14c6a94811fb8114a61b8f3ab29214f9466b5c59  .gradle/caches/modules-2/files-2.1/com.android.tools.lint/lint-api/25.1.3/14c6a94811fb8114a61b8f3ab29214f9466b5c59/lint-api-25.1.3.jar
#即目录名。

#jcenter上jar的路径

https://jcenter.bintray.com/com/android/tools/lint/lint-api/25.1.3/lint-api-25.1.3.jar

#对应的缓存目录为

.gradle/caches/modules-2/files-2.1/com.android.tools.lint/lint-api/25.1.3/${shasum1}/lint-api-25.1.3.jar

#看下这个目录下有什么？

~ find .gradle/caches/modules-2/files-2.1/com.android.tools.lint/lint-api/25.1.3/ -type f

#除了jar包还有pom，用于描述jar。

.gradle/caches/modules-2/files-2.1/com.android.tools.lint/lint-api/25.1.3/14c6a94811fb8114a61b8f3ab29214f9466b5c59/lint-api-25.1.3.jar

.gradle/caches/modules-2/files-2.1/com.android.tools.lint/lint-api/25.1.3/c4844e26d84dd1f450f90d89d7e2d2d09f52760/lint-api-25.1.3.pom

#看下jar的shasum

~ shasum .gradle/caches/modules-2/files-2.1/com.android.tools.lint/lint-api/25.1.3/14c6a94811fb8114a61b8f3ab29214f9466b5c59/lint-api-25.1.3.jar

#即目录名。

注意：创建jcenter时，对于jar包，可以没有pom，但是如果使用aar，则必须有pom，所以最好是每个版本都有个pom。因为pom中也描述了依赖关系。

3 daemon目录（无需离线）

用于存放gradle daemon的运行日志。按gradle程序版本存放。

目录 | 功能
2.14.1 | gradle-2.14.1运行的日志
3.2.1 | gradle-3.2.1运行的日志

4 native目录（无需离线）

用于存放平台相关（Windows/Linux/Mac）的库。

目录 | 功能
19 | gradle-2.14.1对应的lib目录，按平台存放，如osx-amd64
21 | gradle-3.2.1对应的lib目录，按平台存放，如osx-amd64
jansi | ?

5 wrapper目录

用于存放gradle-wrapper下载gradle的zip包和解压后的文件夹。
wrapper的目录规则是
wrapper/dists/gradle-2.14.1-all/ $b a s e 36 / g r a d l e - 2.14 .1 - a l l . z i p w r a p p e r / d i s t s / g r a d l e - 2.14 .1 - a l l /$ {base36}/gradle-2.14.1-all.zip.lck
wrapper/dists/gradle-2.14.1-all/${base36}/gradle-2.14.1-all.zip.ok

其中base36的规则为：

从gradle/wrapper/gradle-wrapper.properties中得到distributionUrl，即https://services.gradle.org/distributions/gradle-2.14.1-all.zip，注意文件中的\不算。
对distributionUrl计算md5。例如printf “https://services.gradle.org/distributions/gradle-2.14.1-all.zip” | md5
得到8c9a3200746e2de49722587c1108fe87。
利用0x8c9a3200746e2de49722587c1108fe87构造一个uint 128位整数。
将整数利用base36得到base36的值（取小写）。

从gradle-wrapper的jar包中提取的Java代码如下：

import java.math.BigInteger;
import java.security.MessageDigest;

public class Hash {

    public static void main(String[] args) {
        try {
            MessageDigest messageDigest = MessageDigest.getInstance("MD5");
            byte[] bytes = args[0].getBytes();
            messageDigest.update(bytes);
            String str = new BigInteger(1, messageDigest.digest()).toString(36);
            System.out.println(str);
        } catch (Exception e) {
            throw new RuntimeException("Could not hash input string.", e);
        }
    }
}

import java.math.BigInteger;

import java.security.MessageDigest;

public class Hash {

public static void main(String[] args) {

try {

MessageDigest messageDigest = MessageDigest.getInstance("MD5");

byte[] bytes = args[0].getBytes();

messageDigest.update(bytes);

String str = new BigInteger(1, messageDigest.digest()).toString(36);

System.out.println(str);

} catch (Exception e) {

throw new RuntimeException("Could not hash input string.", e);

}

c++跟java代码见http://github.com/xiaoyur347/gradlew/helper。

6. 使用.gradle/caches/modules-2创建jcenter的方法

以下是mirror.sh，我把它放在.gradle目录下。运行脚本会在.gradle目录下生成jcenter目录。把它移走或直接把jcenter目录加入http服务器即可。

目前我的做法是在本地使用gradle编译一次，然后把gradle下载下来的jar/aar/pom全部提交到版本管理，然后由持续集成去拉版本库上的.gradle目录，然后生成jcenter提供给内网编译服务器。

#!/bin/bash
#use .gradle/caches/modules-2/files-2.1/ to create jcenter
SHPATH=$(cd "$(dirname "$0")"; pwd)
DIR="${SHPATH}/caches/modules-2/files-2.1/"
DIR_LENGTH=${#DIR}
if [ `uname` = "Darwin" ]; then
#mac will add "/"
	DIR_LENGTH=$((DIR_LENGTH+1))
fi
rm -rf ${SHPATH}/jcenter/*
find ${DIR} -type f | grep -Ev "DS_Store" | while read line
do
	SRC=${line}
	URL=${line:${DIR_LENGTH}}

	ORG=${URL%%/*}
	URL=${URL#*/}

	MODULE=${URL%%/*}
	URL=${URL#*/}

	REVISION=${URL%%/*}
	URL=${URL#*/}

	SHA1=${URL%%/*}
	URL=${URL#*/}

	FILE=${URL}
#echo "ORG=$ORG, MODULE=$MODULE, REVISION=$REVISION, SHA1=$SHA1, FILE=$FILE"

	DST=${SHPATH}/jcenter/${ORG//.//}/${MODULE}/${REVISION}/${FILE}
echo "$DST"
	mkdir -p `dirname ${DST}`
	if [ ! -f ${DST} ]; then
		cp -a ${SRC} ${DST}
fi
done

#!/bin/bash

#use .gradle/caches/modules-2/files-2.1/ to create jcenter

SHPATH=$(cd "$(dirname "$0")"; pwd)

DIR="${SHPATH}/caches/modules-2/files-2.1/"

DIR_LENGTH=${#DIR}

if [ `uname` = "Darwin" ]; then

#mac will add "/"

DIR_LENGTH=$((DIR_LENGTH+1))

rm -rf ${SHPATH}/jcenter/*

find ${DIR} -type f | grep -Ev "DS_Store" | while read line

SRC=${line}

URL=${line:${DIR_LENGTH}}

ORG=${URL%%/*}

URL=${URL#*/}

MODULE=${URL%%/*}

URL=${URL#*/}

REVISION=${URL%%/*}

URL=${URL#*/}

SHA1=${URL%%/*}

URL=${URL#*/}

FILE=${URL}

#echo "ORG=$ORG, MODULE=$MODULE, REVISION=$REVISION, SHA1=$SHA1, FILE=$FILE"

DST=${SHPATH}/jcenter/${ORG//.//}/${MODULE}/${REVISION}/${FILE}

echo "$DST"

mkdir -p `dirname ${DST}`

if [ ! -f ${DST} ]; then

cp -a ${SRC} ${DST}

done

另外，上面提到aar有可能会因为缺失pom导致无法使用，我还写了一个脚本，也是放在.gradle目录下，用于修复aar问题。本地运行时，可以只运行这个脚本，因为它会顺路执行上面的脚本。

以下是fix_aar_cache.sh的内容：

#!/bin/bash
SHPATH=$(cd "$(dirname "$0")"; pwd)

SRC_DIR=${SHPATH}/jcenter
CACHE_DIR="${SHPATH}/caches/modules-2/files-2.1/"
${SHPATH}/mirror.sh > /dev/null

DIR_LENGTH=${#SRC_DIR}
if [ `uname` = "Darwin" ]; then
#mac will add "/"
	DIR_LENGTH=$((DIR_LENGTH+1))
fi
find ${SRC_DIR} -name "*.aar" | while read line
do
	SRC=${line}
	LOCAL_POM=${SRC/.aar/.pom}
if [ -f ${LOCAL_POM} ]; then
continue
fi
echo "$LOCAL_POM not found"

	URL=${line:${DIR_LENGTH}}
	URL=${URL/.aar/.pom}
	REMOTE_POM=http://maven.aliyun.com/nexus/content/repositories/jcenter/${URL}
	REMOTE_POM_SHA1=${REMOTE_POM}.sha1

	SHA1=`wget -q -O- ${REMOTE_POM_SHA1}`
	SHA1=${SHA1:2} #remove additional \r\n
echo $SHA1
#reverse to get it
	FILE=${URL##*/}
	URL=${URL%/*}

	REVISION=${URL##*/}
	URL=${URL%/*}

	MODULE=${URL##*/}
	URL=${URL%/*}

	ORG=${URL}
echo "ORG=$ORG, MODULE=$MODULE, REVISION=$REVISION, FILE=$FILE"
#org /->.
	DST=${CACHE_DIR}/${ORG//\//\.}/${MODULE}/${REVISION}/${SHA1}/${FILE}
echo "$DST"
	mkdir -p `dirname ${DST}`
	if [ ! -f ${DST} ]; then
		wget -O ${DST} ${REMOTE_POM}
fi
done

#!/bin/bash

SHPATH=$(cd "$(dirname "$0")"; pwd)

SRC_DIR=${SHPATH}/jcenter

CACHE_DIR="${SHPATH}/caches/modules-2/files-2.1/"

${SHPATH}/mirror.sh > /dev/null

DIR_LENGTH=${#SRC_DIR}

if [ `uname` = "Darwin" ]; then

#mac will add "/"

DIR_LENGTH=$((DIR_LENGTH+1))

find ${SRC_DIR} -name "*.aar" | while read line

SRC=${line}

LOCAL_POM=${SRC/.aar/.pom}

if [ -f ${LOCAL_POM} ]; then

continue

echo "$LOCAL_POM not found"

URL=${line:${DIR_LENGTH}}

URL=${URL/.aar/.pom}

REMOTE_POM=http://maven.aliyun.com/nexus/content/repositories/jcenter/${URL}

REMOTE_POM_SHA1=${REMOTE_POM}.sha1

集成华为HMS debug/release 修改包名，取不同包名下的agconnect-services.json 文件

debug/release 修改包名，取不同包名下的agconnect-services.json 文件 V2 解决每次更换包名，都是要手动删除agconnect-services.json文件操作

问题描述

集成华为HMS Core/Push在打多渠道包的时候，我需要区分debug版本，release版本，其中涉及到包名的不同，我使用release编译的时候，发现如下错误信息。这个原因是因为你的agconnect-services文件里面含有一个 package_name 参数，这个参数是需要指定包名的，如果 package_name 填写的报名，和目前你所使用的包名没有对应上就会出现这样的错误

修改过程中遇到的错误信息

* What went wrong:
Execution failed for task ':app:processDebugAGCPlugin'.
> ERROR: Failed to verify AGConnect-Config '/client/package_name', expected: 'com.gxx.fast', but was: 'com.gxx.fast.debug'

* What went wrong:

Execution failed for task ':app:processDebugAGCPlugin'.

> ERROR: Failed to verify AGConnect-Config '/client/package_name', expected: 'com.gxx.fast', but was: 'com.gxx.fast.debug'

不是很完美的解决问题

既然是需要区分包名的，我不如直接copy 2份出来，放到src下面，并新建一个类 pushservices 里面存放 debug/release 的类并存放 agconnect-services.json文件，这样我们想使用哪个版本的，就使用哪个版本的

Android开源VPN客户端之ICS OpenVPN

1. 简介

Android API level 14+提供了VPNService服务框架，在不root的情况下，开发者可以创建自己的VPN服务应用。
目前主要有三种，分别为OpenVPN for Android（ICS OpenVPN），OpenVPN Connect，OpenVPN Settings。

OpenVPN for Android和OpenVPN Connect使用官方VPNService API (Android 4.0+)，不需要root权限，而OpenVPN Settings需要root权限。
OpenVPN for Android是一个开源的客户端，由Arne Schwabe开发，他定位于更高级的用户，提供更多的设置，它可以在app内导入配置文件。
OpenVPN Connect是一个不开源的客户端，它由OpenVPN Technologies , Inc. 开发，它定位于普通用户，它基于OpenVPN协议的C++实现。
OpenVPN Settings是最老的客户端，需要root权限，它并不使用VPNService API。

2. 编译OpenVPN for Android

2.1 开发环境搭建

Ubuntu16，Android Studio，NDK，SDK
首先在Ubuntu下安装Android studio，安装完毕后，使用sdk manager工具安装sdk。
关于NDK，可以使用sdk manager来下载，不过在编译源码的过程中出现了错误，经过尝试发现sdk manager下载的是14版本的ndk，而14版本的ndk编译OpenVPN for Android会出现错误，建议使用12版本的ndk。

2.2 配置环境变量

安装完Android studio，解压完ndk后，需要配置环境变量。

~/android-studio/bin Android studio安装目录
~/Android/android-ndk-r12b ndk解压目录

1 2	~/android-studio/bin Android studio安装目录 ~/Android/android-ndk-r12b ndk解压目录

进入用户目录（cd /home/bleach），打开配置文件（vim .bashrc），添加如下内容：

export PATH=$PATH:~/android-studio/bin:~/Android/android-ndk-r12b

1	export PATH=$PATH:~/android-studio/bin:~/Android/android-ndk-r12b

2.3 获取OpenVPN for Android源码

打开搜索引擎，输入ics openvpn，进行搜索，然后进入ics openvpn的github主页，选择master分支里的一个已经添加标签的版本，本文选择的是0.6.64版本的源码。

进入Ubuntu命令行，创建一个源码目录，然后使用git clone命令将源码下载到本地。

$ mkdir ics-openvpn-v0.6.64

$ cd ics-openvpn-v0.6.64

$ git clone https://github.com/schwabe/ics-openvpn.git

$ mkdir ics-openvpn-v0.6.64

$ cd ics-openvpn-v0.6.64

$ git clone https://github.com/schwabe/ics-openvpn.git

2.4 编译源码

step1：进入ics-openvpn-v0.6.64/ics-openvpn目录，修改.gitmodules文件。

$ cd ics-openvpn-v0.6.64/ics-openvpn

$ ls –a

$ vim .gitmodules

$ cd ics-openvpn-v0.6.64/ics-openvpn

$ ls –a

$ vim .gitmodules

将.gitmodules文件中的url更改掉。

[submodule "main/openvpn"]
path = main/openvpn
url = https://github.com/schwabe/openvpn.git

[submodule "main/openssl"]
path = main/openssl
url = https://github.com/schwabe/platform_external_openssl.git

[submodule "main/breakpad"]
path = main/breakpad
url = https://github.com/schwabe/breakpad.git

[submodule "main/openvpn"]

path = main/openvpn

url = https://github.com/schwabe/openvpn.git

[submodule "main/openssl"]

path = main/openssl

url = https://github.com/schwabe/platform_external_openssl.git

[submodule "main/breakpad"]

path = main/breakpad

url = https://github.com/schwabe/breakpad.git

step2：执行指令

$ git submodule sync

1	$ git submodule sync

step3：然后执行指令

$ git submodule init

1	$ git submodule init

step4：然后执行指令

$ git submodule update

1	$ git submodule update

upate指令会消耗一定的时间。
step5：最后进入ics-openvpn-v0.6.64/ics-openvpn/main目录，执行./misc/build-native.sh，等待编译完成，可能需要修改build-native.sh的执行权限。

$ cd main

$ chmod +x ./mics/build-native.sh

$ ./misc/build-native.sh

$ cd main

$ chmod +x ./mics/build-native.sh

$ ./misc/build-native.sh

3. 编译常见问题

3.1 ndk-build not found

未配置ndk环境变量，请参考2.2。

3.2 各种编译错误，比如unknown directive。

很有可能是ndk版本的问题，请使用12版本的ndk尝试编译。

3.3 cannot find .git directory in openvpn,aborting

不要在github上下载zip包的源码，请使用git clone指令将源码下载到本地。

4. 导入源码

将源码导入到Android studio中，目前OpenVPN for Android不支持导入到eclipse中，请使用Android studio开发环境。
打开Android studio，将源码导入，Android studio会自动更新gradle信息，更新完毕后，编译工程，就会生成对应apk包。

oKHttp 3.0忽略/检查https证书

最近公司项目需要，网络协议支持HTTPS，之前接触不多，所以这次想总结一下https在Android开发中的相关内容

一、HTTPS 证书

对于HTTPS和证书的概念，大家可以自行搜索百度。

证书分两种：

1、花钱向认证机构购买的证书。服务器如果使用了此类证书的话，那对于移动端来说，直接可以忽略此证书，直接用https访问。与之不同的是ios内置了很多信任的证书，所以他们不需要做任何操作

2、另一种是自己制作的证书，使用此类证书的话是不受信任的，也不需要花钱，所以需要我们在代码中将此类证书设置为信任证书

二、如何忽略证书

注意，下面的操作在线上环境强烈不建议采纳，只能是在测试环境中解决测试问题的时候才能使用。

1、服务器如果加上了证书的话，那么你们的网络请求的url将从http:xx改成https:xx,如果你直接也将http改成https的话而什么也不做的话，客户端将直接报错，如图：

Android：调整线程调用栈大小

在常规的Android开发过程中，随着业务逻辑越来越复杂，调用栈可能会越来越深，难免会遇到调用栈越界的情况，这种情况下，就需要调整线程栈的大小。

当然，主要还是增大线程栈大小，尤其是存在jni调用的情况下，C++层的栈开销有时候是非常恐怖的，比如说递归调用。

这就需要分三种情况，主线程，自定义线程池，AsyncTask。

主线程的线程栈是没有办法进行修改的，这个没办法处理。

针对线程池的情况，需要在创建线程的时候，调用构造函数

public Thread(@RecentlyNullable ThreadGroup group, @RecentlyNullable Runnable target, @RecentlyNonNull String name, long stackSize)

1	public Thread(@RecentlyNullable ThreadGroup group, @RecentlyNullable Runnable target, @RecentlyNonNull String name, long stackSize)

通过设置stackSize参数来解决问题。
