FW直播源码
❶ 直播声卡哪个牌子好求推荐
好的直播声卡牌子有：
1、雅马哈
雅马哈是众所周知的知名品牌，AG03是雅马哈为数不多的可用于手机直播的外置声卡，可以实现最高的声音还原，其品质在本文所提及的所有品牌中无一可与之媲美。
4、创新
创新的这款产品在同价位来说表现不错，在业界也有一定名气。这款产品没有笑声，鼓掌之类的氛围特效，对于喜欢这类氛围特效的人来说不太合适。
❷ 求一个java实现自动下载的源代码

正常情况下，编译aapt时我们使用的命令是
make aapt11
改造后，我们希望该命令可以编译出官方的aapt，然后通过另一个命令编译出定制版的aapt，这里让其命名为vaapt，当然这个前缀随意，你喜欢就好。最终编译的命令就是
make vaapt11
命令有了，模块在哪里呢？很简单，直接在aapt同级目录下拷贝一个aapt，重名名为vaapt。最终目录结构如图所示
我们还需要修改makefile文件，让其编译出vaapt，依赖的内容也是vaapt，makefile原内容为：
# ==========================================================
# Build the host static library: libaapt
# ==========================================================
include $(CLEAR_VARS)
LOCAL_MODULE := libaapt
LOCAL_MODULE_HOST_OS := darwin linux windows
LOCAL_CFLAGS := -Wno-format-y2k -DSTATIC_ANDROIDFW_FOR_TOOLS $(aaptCFlags)
LOCAL_CPPFLAGS := $(aaptCppFlags)
LOCAL_CFLAGS_darwin := -D_DARWIN_UNLIMITED_STREAMS
LOCAL_SRC_FILES := $(aaptSources)
LOCAL_STATIC_LIBRARIES := $(aaptHostStaticLibs)
LOCAL_STATIC_LIBRARIES_windows := $(aaptHostStaticLibs_windows)
include $(BUILD_HOST_STATIC_LIBRARY)
# ==========================================================
# Build the host executable: aapt
# ==========================================================
include $(CLEAR_VARS)
LOCAL_MODULE := aapt
LOCAL_MODULE_HOST_OS := darwin linux windows
LOCAL_CFLAGS := $(aaptCFlags)
LOCAL_CPPFLAGS := $(aaptCppFlags)
LOCAL_LDLIBS_darwin := $(aaptHostLdLibs_darwin)
LOCAL_LDLIBS_linux := $(aaptHostLdLibs_linux)
LOCAL_SRC_FILES := $(aaptMain)
LOCAL_STATIC_LIBRARIES := libaapt $(aaptHostStaticLibs)
LOCAL_STATIC_LIBRARIES_windows := $(aaptHostStaticLibs_windows)
include $(BUILD_HOST_EXECUTABLE)
# ==========================================================
# Build the host tests: libaapt_tests
# ==========================================================
include $(CLEAR_VARS)
LOCAL_MODULE := libaapt_tests
LOCAL_CFLAGS := $(aaptCFlags)
LOCAL_CPPFLAGS := $(aaptCppFlags)
LOCAL_LDLIBS_darwin := $(aaptHostLdLibs_darwin)
LOCAL_LDLIBS_linux := $(aaptHostLdLibs_linux)
LOCAL_SRC_FILES := $(aaptTests)
LOCAL_C_INCLUDES := $(LOCAL_PATH)
LOCAL_STATIC_LIBRARIES := libaapt $(aaptHostStaticLibs)
LOCAL_STATIC_LIBRARIES_windows := $(aaptHostStaticLibs_windows)
include $(BUILD_HOST_NATIVE_TEST)
可以看到LOCAL_MODULE的值都是aapt相关的，比如static library对应的值是libaapt，host
executable对应的值是aapt，host
tests对应的值是libaapt_tests，还有LOCAL_STATIC_LIBRARIES的值也是依赖static
library，其值为libaapt，我们需要将这几个值修改为vaapt相关的，即在原来的值aapt前面加个v，对应修改为libvaapt、vaapt、libvaapt_tests、libvaapt。修改后的内容如下:
# ==========================================================
# Build the host static library: libaapt
# ==========================================================
include $(CLEAR_VARS)
LOCAL_MODULE := libvaapt
LOCAL_MODULE_HOST_OS := darwin linux windows
LOCAL_CFLAGS := -Wno-format-y2k -DSTATIC_ANDROIDFW_FOR_TOOLS $(aaptCFlags)
LOCAL_CPPFLAGS := $(aaptCppFlags)
LOCAL_CFLAGS_darwin := -D_DARWIN_UNLIMITED_STREAMS
LOCAL_SRC_FILES := $(aaptSources)
LOCAL_STATIC_LIBRARIES := $(aaptHostStaticLibs)
LOCAL_STATIC_LIBRARIES_windows := $(aaptHostStaticLibs_windows)
include $(BUILD_HOST_STATIC_LIBRARY)
# ==========================================================
# Build the host executable: aapt
# ==========================================================
include $(CLEAR_VARS)
LOCAL_MODULE := vaapt
LOCAL_MODULE_HOST_OS := darwin linux windows
LOCAL_CFLAGS := $(aaptCFlags)
LOCAL_CPPFLAGS := $(aaptCppFlags)
LOCAL_LDLIBS_darwin := $(aaptHostLdLibs_darwin)
LOCAL_LDLIBS_linux := $(aaptHostLdLibs_linux)
LOCAL_SRC_FILES := $(aaptMain)
LOCAL_STATIC_LIBRARIES := libvaapt $(aaptHostStaticLibs)
LOCAL_STATIC_LIBRARIES_windows := $(aaptHostStaticLibs_windows)
include $(BUILD_HOST_EXECUTABLE)
# ==========================================================
# Build the host tests: libaapt_tests
# ==========================================================
include $(CLEAR_VARS)
LOCAL_MODULE := libvaapt_tests
LOCAL_CFLAGS := $(aaptCFlags)
LOCAL_CPPFLAGS := $(aaptCppFlags)
LOCAL_LDLIBS_darwin := $(aaptHostLdLibs_darwin)
LOCAL_LDLIBS_linux := $(aaptHostLdLibs_linux)
LOCAL_SRC_FILES := $(aaptTests)
LOCAL_C_INCLUDES := $(LOCAL_PATH)
LOCAL_STATIC_LIBRARIES := libvaapt $(aaptHostStaticLibs)
LOCAL_STATIC_LIBRARIES_windows := $(aaptHostStaticLibs_windows)
include $(BUILD_HOST_NATIVE_TEST)
这时候执行编译命令make
vaapt，完全可以编译出一个vaapt命名的可执行文件。但是事情还没有完，aapt的源码依赖了androidfw下的部分源码，而恰恰这部分源码也可能需要修改，因此我们也需要做同样的事，在同目录下复制一份androidfw为vandroidfw。这个文件夹有两份，一份是头文件，一份是cpp文件，对应在不同的目录。首先来看头文件的目录，在include下
然后是实现的cpp的目录，在libs下
同样的需要修改makefile文件，原文件内容是
# For the host
# =====================================================
include $(CLEAR_VARS)
LOCAL_MODULE:= libandroidfw
LOCAL_MODULE_HOST_OS := darwin linux windows
LOCAL_CFLAGS += -DSTATIC_ANDROIDFW_FOR_TOOLS
LOCAL_CFLAGS += -Wall -Werror -Wunused -Wunreachable-code
LOCAL_SRC_FILES:= $(hostSources)
LOCAL_C_INCLUDES := external/zlib
include $(BUILD_HOST_STATIC_LIBRARY)
# For the device
# =====================================================
include $(CLEAR_VARS)
LOCAL_MODULE:= libandroidfw
LOCAL_SRC_FILES:= $(deviceSources)
LOCAL_C_INCLUDES := \
system/core/include
LOCAL_STATIC_LIBRARIES := libziparchive libbase
LOCAL_SHARED_LIBRARIES := \
libbinder \
liblog \
libcutils \
libgui \
libutils \
libz
需要将LOCAL_MODULE的值从libandroidfw修改为libvandroidfw。
这时候其实还是有问题的，因为文件里的头文件的引用还是androidfw的，会报找不到的错误，因此需要将include/vandroidfw和libs/vandroidfw下的文件内容中头文件的include部分的代码和androidfw相关的都改成vandroidfw。就像这样
这是一个相对痛苦且繁琐的步骤，只要耐住性子改了就可以了，不要遗漏即可。
然后回到vaapt的makefile文件。将对androidfw的引用改成vandroidfw，原内容为
aaptHostStaticLibs := \
libandroidfw \
libpng \
liblog \
libutils \
libcutils \
libexpat \
libziparchive-host \
libbase
修改后的内容为
aaptHostStaticLibs := \
libvandroidfw \
libpng \
liblog \
libutils \
libcutils \
libexpat \
libziparchive-host \
libbase
至此，就完成了一个自定义的aapt的模块的新建和修改，之后只需要修改vaapt下的源码以及vandroidfw下的源码，即可得到自定义的aapt，而不改变原有aapt的源码内容。如果需要编译官方的aapt，只需要用make aapt编译，编译我们自定义的aapt，则使用make vaapt编译，做到了一定的隔离，互不影响。当然如果你乐意，完全可以对vaapt和vandroidfw目录使用git进行版本控制，这样也就能看到我们历史修改了什么内容。
最后推荐一个可以用于差异比较的软件Beyond Compare，跨平台的，windows，mac，linux都有，当然这是一个收费软件。。。所以你懂的。可以用它比较两个目录的aapt之间的差异，效果如下。
