作为@Saurabh Thorat提供的答案，Google不允许应用程序从/data/user目录运行二进制文件.

As the answer provided by @Saurabh Thorat, Google doesn't allow apps to run binary files from /data/user directory.

我知道一个糟糕的解决方案是将compileSdkVersion和targetSdkVersion更改为28或更低，然后重新发布我的应用程序，这是不推荐的.

One bad solution that I know is to change compileSdkVersion and targetSdkVersion to 28 or below and re-release my application which is not recommended.

因此，我也在寻找将来版本的更可行的解决方案.

Hence, I am looking for more viable solutions for future releases as well.

任何提示，链接或建议将不胜感激.预先感谢.

Any hint, links or suggestion would be highly appreciated. Thanks in advance.

推荐答案

仅在Build.gradle文件上更改 targetSdkVersion 29至28 和 在您的设备上重新安装您的应用-由于targetSdkVersion 29是在Play商店上发布版本所必需的平台，因此已解决您的临时权限问题，建议您使用此库

Change only on Build.gradle file targetSdkVersion 29 to 28 and Re-Install your app on your device - It is resolved your permission issue for temporary because of the targetSdkVersion 29 is required platform for released build on play store so I suggest to you use this library
