Question

当我尝试在64位设备上运行时，我的应用程序在32位Android设备上运行完美它给了我构建时间的错误。

错误：

Build command failed.

我使用以下步骤在64位设备上构建应用程序。

在abiFilters中添加“arm64-v8a”
在Application.mk中更新APP_ABI

但的 Android.mk

LOCAL_PATH := $(call my-dir)
MAIN_LOCAL_PATH := $(call my-dir)
include $(CLEAR_VARS)
LOCAL_MODULE := va++


LOCAL_CFLAGS := -Wno-error=format-security -fpermissive -DLOG_TAG=\"VA++\"
LOCAL_CFLAGS += -fno-rtti -fno-exceptions

LOCAL_C_INCLUDES += $(MAIN_LOCAL_PATH)
LOCAL_C_INCLUDES += $(MAIN_LOCAL_PATH)/Foundation
LOCAL_C_INCLUDES += $(MAIN_LOCAL_PATH)/Jni

LOCAL_LDLIBS := -llog -latomic

include $(BUILD_SHARED_LIBRARY)
