因为Bitmap.h缺少的Andr​​oid NDK不会建库？ [英] Android NDK won't build library because Bitmap.h is missing?

问题描述

我在使用Android NDK建立一个图书馆。我拥有了一切运作良好，但我需要改变它在图书馆引用的包名。我试过一次我做了改变，其文件夹中调用NDK的构建又构建库，但是这是唯一的输出我得到的，它似乎并没有完全建设：

I'm using the Android NDK to build a library. I had everything working well, but then I needed to change a package name which is referenced in the library. I tried to build the library again once I made the change, by calling ndk-build in its folder, but this is the only output I get and it does not seem to be fully building:

C:\my-app\jni>ndk-build -B
"Compile++ thumb : filters <= filters.cpp
C:/a-fa-outsidelands//jni/filters.cpp:4:28: fatal error: android/bitmap.h: No such file     or directory
compilation terminated.

这随后导致了不合适的链接错误，当我尝试运行应用程序。我会后我的.mk文件，但我不认为应该的问题，因为我的previous库与此.mk文件上工作。我做的是重建（-b参数），因为它是超过previous构建。有什么建议么？这是我的.mk文件：

This then leads to an unsatisfied link error when I try to run the application. I'll post my .mk file, but I don't think that should matter because my previous library was working with this .mk file. I'm doing the rebuild (the -B parameter) because it is over a previous build. Any suggestions? Here's my .mk file:

LOCAL_PATH := $(call my-dir)

include $(CLEAR_VARS)

LOCAL_MODULE    := filters
LOCAL_SRC_FILES := filters.cpp
LOCAL_LDLIBS    := -lm -llog -ljnigraphics

include $(BUILD_SHARED_LIBRARY)

感谢您的帮助。

推荐答案

什么是的android：targetSdkVersion 在应用程序的清单？ IIRC， bitmap.h 未出台之前，SDK V8。

What's the android:targetSdkVersion in the app's manifest? IIRC, bitmap.h was not introduced until SDK v8.

编辑：当时在同一台机器上的最后一个成功的构建，用同样的NDK版本？是否#include行使用＆LT;机器人/ bitmap.h＆GT; ，而不是的Andr​​oid / bitmap.h ？

Was the last successful build on the same machine, with the same NDK version? Does the #include line use <android/bitmap.h> as opposed to "android/bitmap.h"?

EDIT2：那些自上次编译的targetSdkVersion变化？我发现了一个有趣的事：有没有的android-10 在 Android的NDK-XX \\平台。尝试在 Android的NDK-XX \\平台和复制的内容<$ C创建一个空白的android-10 文件夹$ C> Android的9 那里。我真的不知道要检查什么。

Did the targetSdkVersion change since the last build? I found a funny thing: there's no android-10 under android-ndk-xx\platforms. Try creating a blank android-10 folder under android-ndk-xx\platforms and copying the contents of android-9 there. I'm honestly not sure what else to check.
