在我这边测试的两台 Android 11（oppo 和三星）中，点击修改 Activity Class，在 native-lib.cpp 186 行出现 crash：

                jbyte *transformed(
                        (jbyte *) writer2.CreateImage(&allocator,
                                                      reinterpret_cast<size_t *>(newClassDataLen)));

crash log：

但 Android 11 模拟器没有问题。
