Problem with stack rationale dialog

[mgolebiowski95]

Basic Information

Device type: ________
OS version: ________
EasyPermissions version: 1.0.1

Describe the problem

What happened? What did you expect to happen?

When I executed code below code 0 in onStart() every time show new rationale dialog over previous dialog. If dialog is exist new dialog should'nt show. A good solution would be to add a method that checks whether or not a rationale dialog is shown code 1 and code 2

Code and logs

code 0:
EasyPermissions.requestPermissions(this,
"To function properly, App needs your permissions. Allow permissions for App",
RC_REQUIRED_PERM,
REQUESTED_PERMISSIONS_ON_START);

code 1:

code 2:

// TODO(you): show the code that produces the problem,
execute code 0 in onStart() ex. go to background and returning to application more than 1 time

@mgolebiowski95 can you show your onStart method?

or run this code and change orientation a few times

my requested permisison

You can too add to library method checking android permission dialog is actually showing. In onCreate() bundle savedInstanceState key="android:hasCurrentPermissionsRequest" which contains this value.

I found quite accidentally :-)

@mgolebiowski95 huh that's a cool tip about android:hasCurrentPermissionsRequest. Thanks!

Can you show the crash logs you're getting? Also is your Activity a descendant of AppCompatActivity?

[mgolebiowski95]

I hadn't crash. This is my simple test https://github.com/mgolebiowski95/easypermissionstest. (master, another_idea)

problem: stack rationale dialog

• clear application data -> grand first permission, other deny -> close appsetting dialog -> rotate phone a few times / go to background and return to app

• clear application data -> grand first permission, other deny -> rotate phone a few times / go to background and return to app (rationale dialog stack under appsetting dialog)

Maybe AppSetting Dialog better create based on DialogFragment. Then can check findFragmentByTag is exists.

With android:hasCurrentPermissionsRequest may be problem. When go to background and return to app onCreate() isn't called (only onStart() and onResume() ) and can not update value hasCurrentPermissionsRequest. (there is no access to savedInstanceState bundle)

@mgolebiowski95 thanks for the code, I can confirm that in your situation the dialog does stack. There are two action items here:

• This library should make an attempt to not show the rationale dialog if one is already showing.
• Your app probably should not show the dialog on onStart, the Android UX guidelines for permissions
  requests say to show the request in response to a user action (button click, etc)

#195 will fix this issue
