You cannot have “java.*” package names. This is actually hard-coded in the Java core so you cannot even grant a security manager permission to work around it. Please check if your app package name contains ‘java’ or not.
How to i check my package name contains ‘java’
On screen1, scroll the the right side menu, you will find the Package Name. Search Carefully

but using package name how i know is contain java or not
this is my package name :com.myname.firstname_lastname
Okay. So, does your app asks for any permission? Because these errors raise when you don’t handle the permission carefully.

yes location permission. i asked for permission when home screen initialize
Can you please show the blocks where you are asking for permission?
yes please check below screenshot
If Location Permission is important for your app, then you can do as follows:
i) If Permission Granted, then open another screen. (Don’t use true or false with this block because this block always returns boolean value.)
ii) If ‘Permission Denied’, then close the app.

i used in screen 1 one signal but not used clock in home screen. but i used clock in other all screen.
and about the block i not used any block of one signal and for clock i used only 3 block set timer enable to true falls and when timer
