adviced:

change: com.github.javiersantos.appupdater.AppUpdater

...
348  alertDialog.show();
...

to

...
347        if(((Activity)context).isFinishing()) {
348             alertDialog.show();
349        }
...

You should not compare a boolean with another boolean, but use the boolean ! operator (or nothing) instead. Then, if this is an Activity, you should rather use

if (!YourActivity.this.isFinishing()) {
    alertDialog.show();
}
