尊敬的开发者， 您好，感谢您联系DJI 大疆创新。

我对比了一下你的build.gradle和Sample的，没什么区别。能不能跑跑Sample，我确定Sample不会报这样的错误，你是做了什么操作会导致这样的异常抛出呢？

希望我们的解决方案能够帮到您，感谢您的邮件，祝您生活愉快！ Best Regards, DJI 大疆创新SDK技术支持

abiFilters 'armeabi-v7a',  'arm64-v8a'  增加了 'x86' 之后似乎就没有崩溃了。

我感觉很费解啊。。。安装包体积太大了能不能优化下。给我一个只要一个abi架构的选项

并没有解决：：：：：：：

尊敬的开发者， 您好，感谢您联系DJI 大疆创新。

优化只能在build.gradle里面exclude模块，没有其他的办法。崩溃问题你说加X86能解决，你的手机CPU是X86架构的嘛？

没有解决，今天又这样子了。用as安装启动经常报java.lang.UnsatisfiedLinkError: No implementation found for java.lang.String dji.midware.natives.SDKRelativeJNI.native_getUsbAccessoryAttachedString() (tried Java_dji_midware_natives_SDKRelativeJNI_native_1getUsbAccessoryAttachedString and Java_dji_midware_natives_SDKRelativeJNI_native_1getUsbAccessoryAttachedString__)        at dji.midware.natives.SDKRelativeJNI.native_getUsbAccessoryAttachedString(Native Method)         at dji.sdk.sdkmanager.DJISDKManager.<clinit>(Unknown Source:32)         at dji.sdk.sdkmanager.DJISDKManager.getInstance(Unknown Source:0)

。手动点击桌面图标没有这个问题

@SJJ-dot 你怎么解决的呢，我跑sample没有这个问题，但是在import到自己的项目会有
