我试图在Android智能手表上运行DJI的importSDKDemo sample code，并且当DJISDKManager实例尝试注册应用程序时，在startSDKRegistration（）中出现KeyStore异常。
DJI SDK：v4.9
Android SDK（compileSDKversion）：28
Android设备：具有Wear OS v2.6的Mobvoi TicWatch Pro 0584
Mobvoi TicWatch已连接到我工作场所中的特定WiFi网络，并且调制解调器就在附近，以确保它与我以前使用的公共WiFi网络无关。
除了此问题报告，我找不到与该特定问题有关的任何信息，我尝试应用那里提出的解决方案，但仍然得到KeyStore exceptions
我不确定本文中要包含的代码，但是在DJISDKManager.getInstance.registerApp（...）之后，这是程序停止的部分，通常与importSDKDemo中的版本完全相同。
private void startSDKRegistration() {
if (isRegistrationInProgress.compareAndSet(false, true)) {
AsyncTask.execute(new Runnable() {
@Override
public void run() {
showToast("registering, pls wait...");
DJISDKManager.getInstance().registerApp(MainActivity.this.getApplicationContext(), new DJISDKManager.SDKManagerCallback() {
@Override
public void onRegister(DJIError djiError) {
if (djiError == DJISDKError.REGISTRATION_SUCCESS) {
showToast("Register Success");
DJISDKManager.getInstance().startConnectionToProduct();
} else {
showToast("Register sdk fails, please check the bundle id and network connection!");
}
Log.v(TAG, djiError.getDescription());
}
这是我多次获得的KeyStore异常的完整堆栈：

我希望注册能够正常进行，我收到“ Hello Round World”屏幕和“ Registering pls wait ...” showToast消息，但是在几次KeyStore异常之后，我得到了“ Register sdk失败，请检查捆绑软件ID和网络连接！”来自OnRegister的消息（DJIError djiError） DJIError出现
djiError = {DJISDKError@14580} "The metadata received from server is invalid, please reconnect to the server and try."
如果注册正常完成，则用户应获得“注册成功” showToast消息。
有人知道什么会导致这些KeyStore异常吗？
谢谢您的时间！
