从Android Studio迁移到IntelliJ,从Gradle2升级到Gradle5.4.1,JNI NDK的配置更新

IntelliJ IDEA,是java编程语言开发的集成环境,在业界被公认为最好的java开发工具之一。参考其官网:https://www.jetbrains.com/idea/。

其实不只是Java,同家公司的Android Studio、PHPStorm、WebStorm、PyCharm、RubyMine的功能,它都有,不就是插件嘛!所以,最近把Android Studio、PHPStorm、WebStorm、PyStorm全部干掉了,所有项目都用IntelliJ来开发。

因为IntelliJ的各种插件都比较新,所以,顺带把Android的各种编译工具和环境更新到相对新的版本,也就有了如下采坑总结,记录一下。

1.gradle.properties

#gradle:3.0.1  studio3.0 之前用
#android.useDeprecatedNdk=true
#gradle:3.0.1  studio3.0 之后用
#android.deprecatedNdkCompileLease=1511832698813
org.gradle.daemon=true
org.gradle.configureondemand=true
org.gradle.jvmargs=-Xmx4g -XX:MaxPermSize=2048m -XX:+HeapDumpOnOutOfMemoryError -Dfile.encoding=UTF-8

2.根目录下的:build.gradle

// Top-level build file where you can add configuration options common to all sub-projects/modules.

buildscript {
    repositories {
        maven{url 'http://maven.aliyun.com/nexus/content/groups/public/'}
        google()
//        jcenter {
//            url "http://jcenter.bintray.com/"
//        }
    }
    dependencies {

        classpath 'com.android.tools.build:gradle:3.5.0'
        classpath 'com.mob.sdk:MobSDK:+'
        classpath 'com.mob.sdk:MobSDK-Impl:2018.0710.1743'

        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

allprojects {
    repositories {
        jcenter()
        maven {

        }
    }
}

task clean(type: Delete) {
    delete rootProject.buildDir
}

3.library目录下的:build.gradle

    defaultConfig {
        minSdkVersion 15

5.对应的android.mk

LOCAL_PATH := $(call my-dir)

# Builds a dylib out of test.cpp
# 会清除很多 LOCAL_XXX 变量,不会清除 LOCAL_PATH,基本上是固定的,不需要去动
include $(CLEAR_VARS)
# 需要构建模块的名称,会自动生成相应的 libNDKSample.so 文件,每个模块名称必须唯一,且不含任何空格
LOCAL_MODULE := JniAES
# 包含要构建到模块中的 C 或 C++ 源文件列表
LOCAL_SRC_FILES := KeyValue.c
# 指定这个模块里会用到哪些原生 API,详见:https://developer.android.google.cn/ndk/guides/stable_apis.html
LOCAL_LDLIBS := -llog
# 帮助系统将所有内容连接到一起,固定的,不需要去动
include $(BUILD_SHARED_LIBRARY)

6.对应的Application.mk

# https://developer.android.com/ndk/guides/application_mk.html
# 选择不同的 ABI,多个使用空格作为分隔符,全部是all
APP_ABI := all # armeabi-v7a x86
# 指定要使用的运行时
APP_STL := system
