So i recently switched to android 3.0 (honeycomb) and i’m having some issues with hardware rendering, specifically at a certain custom view i’ve written where I use a font size of 200 to display some text.
Unfortunately it seems the openGLRenderer doesn’t like that kind of rather large font sizes very much, given the error i’m getting in the log:
06-06 16:22:00.080: ERROR/OpenGLRenderer(2503): Font size to large to fit in cache. width, height = 97, 145
Are there ways around this (or ways to fix it) such that I can get the text displayed at the wanted font size?
Just an idea: Perhaps you can convert the font to an outline using Paint.getTextPath(…) and use this path to render the text. This should allow you to resize the path as needed.
It is really a bug in the Android OS inside the Hardware Acceleration modules.
I think that the best way is to ask the system to avoid HW acceleration on TextViews that contain large size text.
To do so, just add in the code:
TextView bigText = (TextView) findViewById(R.id.bigtext); bigText.setLayerType(View.LAYER_TYPE_SOFTWARE, null);
setLayerType method is useful, but unfortunately it is supported just for API >= 11. Developing for API = 8 or less it will become unusable.
If you can, a simple solution is disabling the hardware acceleration just for the activity that is giving you problems. I had this very problem and solved it this way:
<application android:... android:hardwareAccelerated="true" > <activity ...> ... </activity> <activity ... android:hardwareAccelerated="false"> ... </activity> </application>
This solution will disable the hardware acceleration just for the activities where you do not need it and where you aren’t able to display large texts.
