FW直播源碼
❶ 直播音效卡哪個牌子好求推薦
好的直播音效卡牌子有：
1、雅馬哈
雅馬哈是眾所周知的知名品牌，AG03是雅馬哈為數不多的可用於手機直播的外置音效卡，可以實現最高的聲音還原，其品質在本文所提及的所有品牌中無一可與之媲美。
4、創新
創新的這款產品在同價位來說表現不錯，在業界也有一定名氣。這款產品沒有笑聲，鼓掌之類的氛圍特效，對於喜歡這類氛圍特效的人來說不太合適。
❷ 求一個java實現自動下載的源代碼
您好，這樣的：

正常情況下，編譯aapt時我們使用的命令是
make aapt11
改造後，我們希望該命令可以編譯出官方的aapt，然後通過另一個命令編譯出定製版的aapt，這里讓其命名為vaapt，當然這個前綴隨意，你喜歡就好。最終編譯的命令就是
make vaapt11
命令有了，模塊在哪裡呢？很簡單，直接在aapt同級目錄下拷貝一個aapt，重名名為vaapt。最終目錄結構如圖所示
我們還需要修改makefile文件，讓其編譯出vaapt，依賴的內容也是vaapt，makefile原內容為：
# ==========================================================
# 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相關的，比如static library對應的值是libaapt，host
executable對應的值是aapt，host
tests對應的值是libaapt_tests，還有LOCAL_STATIC_LIBRARIES的值也是依賴static
library，其值為libaapt，我們需要將這幾個值修改為vaapt相關的，即在原來的值aapt前面加個v，對應修改為libvaapt、vaapt、libvaapt_tests、libvaapt。修改後的內容如下:
# ==========================================================
# 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)
這時候執行編譯命令make
vaapt，完全可以編譯出一個vaapt命名的可執行文件。但是事情還沒有完，aapt的源碼依賴了androidfw下的部分源碼，而恰恰這部分源碼也可能需要修改，因此我們也需要做同樣的事，在同目錄下復制一份androidfw為vandroidfw。這個文件夾有兩份，一份是頭文件，一份是cpp文件，對應在不同的目錄。首先來看頭文件的目錄，在include下
然後是實現的cpp的目錄，在libs下
同樣的需要修改makefile文件，原文件內容是
# 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
需要將LOCAL_MODULE的值從libandroidfw修改為libvandroidfw。
這時候其實還是有問題的，因為文件里的頭文件的引用還是androidfw的，會報找不到的錯誤，因此需要將include/vandroidfw和libs/vandroidfw下的文件內容中頭文件的include部分的代碼和androidfw相關的都改成vandroidfw。就像這樣
這是一個相對痛苦且繁瑣的步驟，只要耐住性子改了就可以了，不要遺漏即可。
然後回到vaapt的makefile文件。將對androidfw的引用改成vandroidfw，原內容為
aaptHostStaticLibs := \
libandroidfw \
libpng \
liblog \
libutils \
libcutils \
libexpat \
libziparchive-host \
libbase
修改後的內容為
aaptHostStaticLibs := \
libvandroidfw \
libpng \
liblog \
libutils \
libcutils \
libexpat \
libziparchive-host \
libbase
至此，就完成了一個自定義的aapt的模塊的新建和修改，之後只需要修改vaapt下的源碼以及vandroidfw下的源碼，即可得到自定義的aapt，而不改變原有aapt的源碼內容。如果需要編譯官方的aapt，只需要用make aapt編譯，編譯我們自定義的aapt，則使用make vaapt編譯，做到了一定的隔離，互不影響。當然如果你樂意，完全可以對vaapt和vandroidfw目錄使用git進行版本控制，這樣也就能看到我們歷史修改了什麼內容。
最後推薦一個可以用於差異比較的軟體Beyond Compare，跨平台的，windows，mac，linux都有，當然這是一個收費軟體。。。所以你懂的。可以用它比較兩個目錄的aapt之間的差異，效果如下。
