Why when installing the application on Android does not require permissions?

Hello to all. I have such a problem: when installing an application on Android that has already been previously processed, I no longer require permission to access the phone’s memory, etc. Therefore, saving does not work, you can fix it if you go into the android settings, find the application and set permissions there. after that everything works again. Tell me what could be the matter? Perhaps the fact is that I mistakenly deleted line 3 in the picture, but then I returned it. Thank you.

I found a pattern, after which the application when installing no longer require permission to access the phone memory, etc.Look at the picture.

And if after this to return settings to the previous ones, even after a full re-package remains the same problem with lack of access requirements. Google play requires a minimum API level of 26.

I solved the problem myself, it turned out that for Android 6.0 and above, the resolution is asked in the process of need. it was necessary to attribute in the code the first time you create a save request for permission. That is all.
