前言：Opus可以實現1kyte/s的壓縮語音傳輸，過癮！

碰到的問題：
原始碼來自：https://wiki.mumble.info/wiki/Main_Page
1、缺少方法 error: use of undeclared identifier 'celt_mode_info'
分析思路：專案裡查詢celt_mode_info ，發現celt-0.11.0 不存在此方法，而celt-0.7 存在，去官方github發現已停止維護
解決方法：遮蔽 Jumble/src/main/jni/Android.mk 的編譯so宣告，即不使用11版本，成功通過；
include $(CLEAR_VARS)
LOCAL_PATH:= $(ROOT)/celt-0.11.0-src/libcelt
LOCAL_MODULE:= jnicelt11
LOCAL_SRC_FILES:= bands.c celt.c cwrs.c entcode.c entdec.c entenc.c header.c kiss_fft.c \
                       laplace.c mathops.c mdct.c modes.c pitch.c plc.c quant_bands.c rate.c vq.c \
                       $(ROOT)/jnicelt11.cpp
LOCAL_C_INCLUDES    := $(ROOT)/celt-0.11.0-src/libcelt/
LOCAL_CFLAGS:= -I$(ROOT)/celt-0.11.0-build -DHAVE_CONFIG_H -fvisibility=hidden
LOCAL_CPP_FEATURES := exceptions
LOCAL_LDLIBS := -llog
include $(BUILD_SHARED_LIBRARY)


2、用了最新的opus-1.1.2 編譯提示錯誤，這個版本在iOS上可以通過，但在Android指令碼上不行，按照Jumble原始碼的link，下載v1.1  …
 65471dd 即可編譯通過


3、armeabi build的錯誤日誌沒拷貝，切記修改ndk版本為 r13b以下，高版本不能編譯！
   編譯 專案 talkiewalkie 一樣的問題。
三個地方：
1）local.properties: ndk.dir=/work_tools/android-ndk-r13b
2) jnigen.h: /work_tools/android-ndk-r13b/ndk-build -C src/main/jni
3) build.gradle:  commandLine '/work_tools/android-ndk-r13b/ndk-build', '-C', file('src/main/jni/').absolutePath
另外後面兩個檔案要用全路徑，預設是不帶全路徑的，不改我的編譯會報錯。我用 MAC系統，應該是系統變數沒設定。


其他：
1）Error:Configuration with name 'default' not found.自行google找解決方法
2）多語言檔案編譯錯誤，不影響；
3) gradle project sync failed. please fix your project and try again 自行google找解決方法




好了，覺得解決你問題的話，記得打賞我的支付寶：

。。。

"certificatePasswordSum" is translated here but not found in default locale [ExtraTranslation]
  <string name="certificatePasswordSum">Das Passwort für Ihr PKCS12 Zertifikat. (Optional)</string>
          ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    /work_studio/mumbleServer/Plumble-android/app/src/main/res/values-es/preference.xml:31: Also translated here
    /work_studio/mumbleServer/Plumble-android/app/src/main/res/values-fr/preference.xml:31: Also translated here
    /work_studio/mumbleServer/Plumble-android/app/src/main/res/values-ja/preference.xml:31: Also translated here
    /work_studio/mumbleServer/Plumble-android/app/src/main/res/values-nl/preference.xml:31: Also translated here
    /work_studio/mumbleServer/Plumble-android/app/src/main/res/values-pl/preference.xml:13: Also translated here
    /work_studio/mumbleServer/Plumble-android/app/src/main/res/values-ru/preference.xml:31: Also translated here


   Explanation for issues of type "ExtraTranslation":
   If a string appears in a specific language translation file, but there is
   no corresponding string in the default locale, then this string is probably
   unused. (It's technically possible that your application is only intended
   to run in a specific locale, but it's still a good idea to provide a
   fallback.).


   Note that these strings can lead to crashes if the string is looked up on
   any locale not providing a translation, so it's important to clean them
   up.
