TabLayout + ViewPager + Fragment + 百度地图 + 传感器 + 自定义View + AIDL

目录结构

TabLayout + ViewPager + Fragment + 百度地图 + 传感器 + 自定义View + AIDL

导入依赖 -- 自己搜索

compile 'com.android.support:design:26.0.0-alpha1'

在百度开发平台上, 申请 AK

导入百度需要的jar包和 so包 , 到libs 中

jar 包关联到工程中 -- 右键 -- Add as library

so包关联在工程中 -- 需要在 build.gradle中 adnroid {} 内部添加

sourceSets{
    main(){
        jniLibs.srcDir 'libs'
        //说明so的路径为该libs路径，关联所有地图SDK的so文件
    }
}

    };

    @Nullable
    @Override
