Android：帮助在Android中编译SoundTouch库

我正在尝试用androidndk编译lib。我从中得到了一些在android中编译这个库的指令

但当我尝试使用

ndk build

命令编译它时，它会在SoundTouch lib的各种源文件中显示错误，如下所示：

我试图按照说明中所述关闭异常处理，但似乎不起作用

我将所有文件从SoundTouch source复制到我项目的JNI文件夹中。这是我的

android.mk

文件：

LOCAL_PATH:= $(call my-dir)
include $(CLEAR_VARS)

LOCAL_CFLAGS :- -frtti -fexceptions

LOCAL_SRC_FILES := AAFilter.cpp BPMDetect.cpp cpu_detect_x86.cpp FIFOSampleBuffer.cpp FIRFilter.cpp main.cpp mmx_optimized.cpp PeakFinder.cpp RateTransposer.cpp RunParameters.cpp SoundTouch.cpp sse_optimized.cpp TDStretch.cpp WavFile.cpp

LOCAL_LDLIBS := -lpcap

LOCAL_MODULE := libSoundTouch

LOCAL_C_INCLUDES := BPMDetect.h FIFOSampleBuffer.h FIFOSamplePipe.h SoundTouch.h STTypes.h

include $(BUILD_SHARED_LIBRARY)

有人能帮我在android上编译和使用SoundTouch库吗

更新：

我更改了我的

android.mk

文件，如下所示

LOCAL_PATH:= $(call my-dir)
include $(CLEAR_VARS)

LOCAL_CPP_FEATURES += -fno-exceptions

LOCAL_SRC_FILES := \
     SoundTouch/AAFilter.cpp \
     SoundTouch/BPMDetect.cpp \
     SoundTouch/cpu_detect_x86.cpp\
      SoundTouch/FIFOSampleBuffer.cpp \
      SoundTouch/FIRFilter.cpp \
      SoundTouch/mmx_optimized.cpp \
      SoundTouch/PeakFinder.cpp \
      SoundTouch/RateTransposer.cpp \
      SoundTouch/SoundTouch.cpp \
      SoundTouch/sse_optimized.cpp \
      SoundTouch/TDStretch.cpp 

LOCAL_MODULE := libSoundTouch

LOCAL_C_INCLUDES := include/BPMDetect.h include/FIFOSampleBuffer.h include/FIFOSamplePipe.h include/SoundTouch.h include/STTypes.h

include $(BUILD_SHARED_LIBRARY)

现在一切正常。谢谢

我已通过更改我的

android.mk

文件成功编译：

这是我的

android.mk

include $(CLEAR_VARS)
LOCAL_PATH:= $(call my-dir)

检查链接这家伙已经编译准备使用SoundTouch Android包装

• 目前能够进行时间拉伸和音高变换
• 目前仅支持带有FPU（armeabi-v7a）的Androids

用法示例：

//There are currently 16 track id's you can use (0-15), each one has a separate SoundTouch processor.

    //Set your audio processing requirements: track id, channels, samplingRate, bytesPerSample, 
    //                              tempoChange (1.0 is normal speed), pitchChange (in semi-tones)

    SoundTouch soundTouch = new SoundTouch(0, 2, 44100, 2, 1.0f, 2.0f);

    //byte[] sizes are recommended to be 8192 bytes.

    //put a byte[] of PCM audio in the sound processor:
    soundTouch.putBytes(input);

    //write output to a byte[]:
    int bytesReceived = soundTouch.getBytes(output);

    //after you write the last byte[], call finish().
    soundTouch.finish();

    //now get the remaining bytes from the sound processor.
    int bytesReceived = 0;
    do
    {
        bytesReceived = soundTouch.getBytes(output);
        //do stuff with output.
    } while (bytesReceived != 0)

    //if you stop playing, call clear on the track to clear the pipeline for later use.
    soundTouch.clearBuffer()

要启用异常，您需要在Android.mk文件中使用“LOCAL_CPP_FEATURES:=exceptions rtti”。您遇到的第一个错误是什么？具体是在哪一行？嘿，您为构建此库做了哪些工作？？只需在新的Android项目中复制Android.mk、Aplication.mk和soundtouch-jni.cpp。并通过NDK build命令构建它…我正在执行这些步骤，但它给了我错误..类似于“”要启用异常，您需要在Android.mk文件中使用“LOCAL_CPP_FEATURES:=exceptions rtti”。您遇到的第一个错误是什么？具体是在哪一行？嘿，您为构建此库做了哪些工作？？只需在新的Android项目中复制Android.mk、Aplication.mk和soundtouch-jni.cpp。并通过NDK build命令构建它…我正在遵循这些步骤，但它给了我错误..类似于“”有人可以帮助使用此库吗？有人可以帮助使用此库吗？这家伙已将代码库移动到github上的新repo我已更新链接。这家伙已经将代码库移动到github上的新repo，我已经更新了链接。
