Android Scanlibrary在西奥米的崩溃

Question

我使用的是来自ScanLibrary的这里。我已经成功地实现了这一点，它在所有的设备上都很好，除了西奥米。我不知道它为什么不适用于秀美。我也在Marshmallow，Lollipop和其他api上测试过，而且它在所有其他设备上都能正常工作，只有Xiomi有问题。我也试图在他们的github页面上报告这一点，但没有得到回复，所以我最后的希望是堆栈溢出。请你看，我搞不懂为什么它不适用于小米。

我在西奥米设备上得到了以下例外：

请看看是否有任何问题，使我的应用程序崩溃的米设备。提前谢谢！

Answer 1

经过几次尝试，我找到了这个解决方案

我对格拉德尔做了一些改变，现在一切都好了

在defaultConfig{}应用程序gradle.build中添加这些行

defaultConfig{
       ndk {
            abiFilters "armeabi-v7a", "x86", "armeabi", "mips"
          }
     }

以及gradle.properties中的一些变化

android.useDeprecatedNdk=true

现在它对我有用了。我想这也会对某人有帮助
