title: ImportSDKDemo Tutorial Issue : No implementation found for byte[] dji.midware.natives.SDKRelativeJNI.native_getXXXX(java.lang.String)
body: <p>I have a problem trying to emulate the <em>ImportSDKDemo</em> project.</p>
  
  <p>I am following this <a href="https://developer.dji.com/mobile-sdk/documentation/application-development-workflow/workflow-integrate.html" rel="noreferrer">tutorial</a>, but there is a missing information, e.g. about <code>MainActivity.class</code>.</p>
  
  <p>When I try to run the emulation I get the following error:</p>
  
  <blockquote>
    <p>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)</p>

  <p>Here is the whole log:</p>
