Android Studio使用gradle实现资源自动拷贝

把下面的代码拷贝到app的gradle.build文件内

android.applicationVariants.all{ variant ->
    delete "${buildDir}/intermediates/merged_assets/${variant.dirName}"  // buildDir是app下的build目录
    variant.mergeAssets.doLast{
        def sourceDir = "${buildDir}/../"   // 资源存放目录，这里是app下
        print "${buildDir} \n"  // 打印路径
        copy { // 将from目录下的资源拷贝到into 下目录去
            from "${sourceDir}/fromDir"
            into "${outputDir}/res"
        }
    }
}

android.applicationVariants.all{ variant ->

delete "${buildDir}/intermediates/merged_assets/${variant.dirName}" // buildDir是app下的build目录

variant.mergeAssets.doLast{

def sourceDir = "${buildDir}/../" // 资源存放目录，这里是app下

print "${buildDir} \n" // 打印路径

copy { // 将from目录下的资源拷贝到into 下目录去

from "${sourceDir}/fromDir"

into "${outputDir}/res"

}

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。

参考代码如下：

/**

    @Override
    public Thread newThread(@NonNull final Runnable runnable) {
        final Thread thread = new Thread(group, runnable, "PoolWorkerThread", workerStackSize);
        // A exception handler is created to log the exception from threads
        thread.setUncaughtExceptionHandler(new Thread.UncaughtExceptionHandler() {
            @Override
            public void uncaughtException(@NonNull Thread thread, @NonNull Throwable ex) {
                Log.e(TAG, thread.getName() + " encountered an error: " + ex.getMessage());
