"nativeLibraryDirectories=[/data/app/com.lukouapp-1/lib/arm64, /vendor/lib64, /system/lib64]]] couldn't find "libxxxx.so"

错误日志：
"nativeLibraryDirectories=[/data/app/com.lukouapp-1/lib/arm64, /vendor/lib64, /system/lib64]]] couldn't find "libxxxx.so"
问题原因：64位机器默认去查找arm64-v8a目录下是否有合适的64位库，如果没有则回去libs下查找32位的库，而fresco的draw-pipeline太完善了考虑了64位的机器所以他的arm64-v8a下有so库，对应的系统就创建了lib64的文件，而不再去找32位的库。
解决办法一：

*修改前：

Edit your build.gradle file as follows:
android {
 // rest of your app's logic
 splits {
   abi {
       enable true
       reset() include 'x86', 'x86_64', 'arm64-v8a', 'armeabi-v7a', 'armeabi'
       universalApk false
    }
  }
}

*修改后：

Edit your build.gradle file as follows:
android {
 // rest of your app's logic
 splits {
   abi {
       enable true
       reset() include 'x86', 'x86_64', 'armeabi-v7a', 'armeabi'
       universalApk false
    }
  }
}

注意：如果加入上面代码还不行 ，可以注释掉下面这行（如果你的主要工程目录没有加入lib和jar的话）

dependencies {
  // compile fileTree(include: ['*.jar'], dir: 'libs')
 }

解决办法二：
也是通过修改gradle文件，
*修改前：

   defaultConfig {
        applicationId "com.richinfo.travel"
        minSdkVersion 10
        targetSdkVersion 22
        versionCode 3
        versionName "1.0.2"
        buildConfigField "boolean", "LOG_DEBUG", "true"
        consumerProguardFiles 'proguard-file.txt'
        manifestPlaceholders =[UMENG_CHANNEL_VALUE: "local"]
    }

*修改后：

defaultConfig {
    applicationId "com.richinfo.travel"
    minSdkVersion 14
    targetSdkVersion 22
    versionCode 3
    versionName "1.0.2"
    buildConfigField "boolean", "LOG_DEBUG", "true"
    consumerProguardFiles 'proguard-file.txt'
    manifestPlaceholders = [UMENG_CHANNEL_VALUE: "local"]
    ndk {
        abiFilters "armeabi", "armeabi-v7a", "x86", "mips"
    }}
