Runtime NullPointerEXception

我在运行hello world 的时候 会报一个空指针错误 ，我看了一下是由于 这个文件 不存在 导致 的
`private final static String TEE_SDK_SIGNED_PACKAGE_PATH = "lib_tee_sdk_svm_load.signed";`
请问这里还需要什么额外的步骤来生成这个对应 的文件 吗

Start by reproducing the NullPointerException while running the hello world example and inspect the reference to TEE_SDK_SIGNED_PACKAGE_PATH, which names lib_tee_sdk_svm_load.signed. Determine from the repository’s documented setup or build entry points how this signed file is produced or supplied; done means the hello world run finds it and no longer fails with the reported null pointer.
