Question

我想编译c ++中的binder本机代码我已经下载了4.04版的本机源代码。

当我尝试构建这个库时，它会给我以下错误：

    Android NDK: WARNING: APP_PLATFORM android-15 is larger than android:minSdkVersion 8 in ./AndroidManifest.xml

LOCAL_SHARED_LIBRARIES := liblog libcutils libutils
LOCAL_SRC_FILES := $(sources)
include $(BUILD_SHARED_LIBRARY)

我经常搜索但是找不到任何帮助。任何帮助将非常感激

从jni中删除以前生成的“obj”文件，然后添加如下所示的android.mk文件

  LOCAL_PATH := $(call my-dir)

  include $(CLEAR_VARS)
  LOCAL_MODULE    := "your shared library name"// while compile it will be generated as [.so]
 LOCAL_SRC_FILES := \
 Binder.cpp \
 BpBinder.cpp \
 CursorWindow.cpp \
 IInterface.cpp \
 IMemory.cpp \
 IPCThreadState.cpp \
 IPermissionController.cpp \
 IServiceManager.cpp \
 MemoryDealer.cpp \
 MemoryBase.cpp \
 MemoryHeapBase.cpp \
 MemoryHeapPmem.cpp \
 Parcel.cpp \
 PermissionCache.cpp \
 ProcessState.cpp \
 Static.cpp


include $(BUILD_SHARED_LIBRARY)
