谁能告诉我如何在camelcase命名策略中重命名play_size_32,play_url_24_m4a等变量？我正在反序列化json字符串,但我不知道如何处理这样的变量名称.

将Android Studio更新到2.3.3并更新ndk软件包后,我的项目无法构建.错误是什么意思？它应该是IDE的错误.如何解决问题或如何回到以前的Android Studio/ndk版本？

生成文档说，复杂条件的语法如下：

conditional-directive-one
text-if-one-is-true
else conditional-directive-two
text-if-two-is-true
else
text-if-one-and-two-are-false
endif

但是我不明白如何使用这种语法来重写以下代码：

ifeq ($(option), 1)
CC=gcc
@echo use gcc
else ifeq($(option), 2)
CC=clang
@echo use clang
else
CC=mipsel-linux-gcc
@echo use mipsel-linux-gcc
endif

#first target
foo: ;
