Black screen with Launch Activity without Toolbar. about dexter HOT 7 CLOSED

Hi @marcellogalhardo

I now understand what's happening, as you pointed out, the important thing is the noHistory = "true" config. When Dexter is called, it creates a new activity internally to request the permissions and pushes it into the stack, this causes your LoginActivity to be completely removed as it's not the top activity anymore (http://developer.android.com/guide/topics/manifest/activity-element.html#nohist).
Whatever it draws under the DexterActivity is left to our imagination (usually a black background or the launcher if the removed activity was the only one).

Sadly, I don't see how we can handle that scenario, the only viable solution would be to use your own activity to request permissions and that's something that you can probably do better on your own instead of using Dexter.

I added a disclaimer in the README warning users of the library to don't use the noHistory flag.

I discovered that the problem occurs in one Activity that has set in its manifest tag: android: noHistory = "true". This is a bug or was it my fault?

Hi @marcellogalhardo,

I'd have to do some testing but I'd say that the themes system is somehow conflicting, keep in mind that the inner DexterActivity instance is using a non-appcompat theme (our bad and something we should probably take a look at).

I'll try to reproduce and debug the issue this week and let you know our findings.

Thanks for reporting!

I've been trying with several configurations but I can't reproduce your problem.
It would be much easier for us if you can provide us with a minimum project where the bug happens.

Either that or you can wait until we release a new version of Dexter which presumably will contain a fix to how we handle the inner activity but I'm not sure if it'll solve your problem.

Thank you for the feedback. I will create a project with the problem to provide for you this week!

@Serchinastico the code is available in the repository: Bug Dexter Black Screen.

Note the following details:

• Styles: AppTheme.
• AndroidManifest: Activity android: noHistory = "true"

When you start the application, it should display a white screen says "Hello World."
When the permission dialog appears, select the "Deny" option.

Note that the application will behave in the following ways:

• Will keep a black screen (usually on the first run).
• Will close the application (the next time).

I hope this helps.
