Singleton DialogManager break the library

[devnied]

When we want to show the rate dialog in multiple Activity or in the same activity, if the first activity that call AppRate.showRateDialogIfMeetsConditions(this); is destroyed. The next call will fail with:

java.lang.RuntimeException: Unable to resume activity {xxx/xxx.HomeActivity}: android.view.WindowManager$BadTokenException: Unable to add window -- token android.os.BinderProxy@b857bc1 is not valid; is your activity running?

The DialogManager Singleton hold the first activity as context and reuse it even it was destroyed.

If you want to keep the singleton, I think the createDialogManager function must check if the singleton context is not destroyed before reuse it.

This issue is linked to #5.
ps: I have tested with the version 1.1.9 and with the latest commit into the master branch.

Hi @devnied,

Thank you!

It's my mistake. I was so sure that it was Application Context that I didn't even look at the code. Key moment - it's Activity Context, not Application Context.
