 # CZXing
 C++ port of ZXing for Android
 
-底层使用C++来处理图像及解析二维码，并且加入了OpenCV来解析图像，可以在更远的距离识别出二维码。

 ### 使用
 在gradle中:
 ``` groovy
-implementation 'me.devilsen:CZXing:0.9.10'
+implementation 'me.devilsen:CZXing:0.9.11'
 ```
 建议加入abiFilters
 ```gradle
-    defaultConfig {
-        
-        // 其他设置...
-
-        ndk {
-            // 设置支持的so库架构，设置一个可以减小包的大小
-            abiFilters "armeabi-v7a","arm64-v8a"
-        }
+defaultConfig {

+    ndk {
+        // 设置支持的so库架构，设置一个可以减小包的大小
+        abiFilters "armeabi-v7a","arm64-v8a"
     }
+}
 ```
 如果下载失败，可以在根目录加入阿里云的镜像
