ImportSDKDemo教程问题：未找到byte []的实现dji.midware.natives.SDKRelativeJNI.native_getXXXX(java.lang.String)

我在尝试模仿ImportSDKDemo项目时遇到问题.

我正在追踪此tutorial,但缺少信息,例如关于MainActivity.class.

当我尝试运行仿真时,出现以下错误：

java.lang.UnsatisfiedLinkError: No implementation found for byte[]
dji.midware.natives.SDKRelativeJNI.native_getXXXX(java.lang.String)
(tried Java_dji_midware_natives_SDKRelativeJNI_native_1getXXXX and
Java_dji_midware_natives_SDKRelativeJNI_native_1getXXXX__Ljava_lang_String_2)

这是整个日志：

我该如何解决这个问题？

随意询问代码或屏幕截图:)

解决方法:

因此,您似乎正在使用4.7.1 SDK,并且可能针对的是现代Android SDK.您遇到的问题是DJI决定捆绑一个libffmpeg.so版本,该版本与x86平台上的现代SDK版本不兼容(仿真器在x86平台上运行).

您有2个,可能是三个选项：

>在Android Studio中,当您创建新的虚拟设备时,当您选择“选择系统映像”时,转到“其他映像”选项卡.从那里选择任何“手臂”图像并使用它.使用此选项,仿真器将非常慢,并且如果您的计算机旧或慢,可能根本无法运行.
>在启用调试模式的情况下,将真实的Android设备连接到计算机,然后在该设备上运行演示.
>在build.gradle文件中,将compileSdkVersion和targetSdkVersion设置为23,这是DJI提供的libffmpeg.so文件将加载的最新版本.不过,这是最糟糕的选择,因为Google不再允许任何人发布具有如此低SDK版本的应用.现在的版本必须是26或更高版本：https://support.google.com/googleplay/android-developer/answer/113469#targetsdk
