Crash using EvaporateTextView! about htextview HOT 15 CLOSED

clearly, this library can not be used in production, I would think it really needs more time to be fixed, several issues are still unresolved.

from htextview.

I also experienced the same error on version 0.1.0, 0.1.1 and 0.1.2 of the library. I am now going to see if 0.1.6 has the problem fixed...

I have the same errore for the ScaleTextView and I resolve like this:

   ViewTreeObserver vto = scaleTextView.getViewTreeObserver();
    vto.addOnGlobalLayoutListener(new ViewTreeObserver.OnGlobalLayoutListener() {
        @Override
        public void onGlobalLayout() {
            scaleTextView.getViewTreeObserver().removeOnGlobalLayoutListener(this);
            scaleTextView.animateText("YOUR NIGHT LIFE PLANNER");
        }
    });

This is because android.text.Layout is null untill the view is ready.

@hanks-zyh Umm... This is marked closed but I'm still getting this error.

Using version 0.1.6 right now.
So I'm reading the cpufreq continuously (at 1500ms intervals) using a thread and then update a HTextview (scale) on the main (UI) thread using a runnable and posting it using a handler with Looper.getmainlooper(). The runnable has the animateText call in it.

The thread is run from within a fragment. So I stop the thread onStop of the fragment to stop extra resource consumption by the thread and I restart the thread onResume of the fragment. Now if I turn off my screen, it calls onStop (and I have confirmed it is called) which stops the thread but when I turn the screen back on again, onResume is called and I restart the thread and that's when the crash happens and dumps the following log :

java.lang.NullPointerException: Attempt to invoke virtual method 'float android.text.Layout.getLineLeft(int)' on a null object reference at com.hanks.htextview.scale.ScaleText.drawFrame(ScaleText.java:98) at com.hanks.htextview.base.HText.onDraw(HText.java:114) at com.hanks.htextview.scale.ScaleTextView.onDraw(ScaleTextView.java:44) at android.view.View.draw(View.java:17209) at android.view.View.updateDisplayListIfDirty(View.java:16191) at android.view.View.draw(View.java:16975) at android.view.ViewGroup.drawChild(ViewGroup.java:3727) at android.view.ViewGroup.dispatchDraw(ViewGroup.java:3513) at android.support.constraint.ConstraintLayout.dispatchDraw(ConstraintLayout.java:1966) at android.view.View.updateDisplayListIfDirty(View.java:16186)

I have tried using a simple android textview instead of HTextview and it works fine. And also from looking at the log I'm confident there's nothing wrong with my own logic implementations. Looks like an internal issue with the HTextview so I dropped this post here.

Edit 1 :
I noticed a weird thing. If I turn off and then turn on my screen, the app crashes with the above log.
But, if I switch to some other app first, like opening settings from the notifications area, the app doesn't crash in bg, and it also resumes fine after picking it from recents. Lockscreen is causing an issue.

If you need some more things like some code parts from my app or stuff like that I will happily provide it for fixing this issue.
