How to handle Android loaded font memory leaks

During the development of the Android app, some external fonts are used. External fonts are prone to memory leaks when loaded.

Like what:

Typeface tf=Typeface.createfromasset (Getassets (), Consts.lanting_font_path); Title.settypeface (TF);

If you write this way every time you call, it will reload the font every time it executes, causing the memory to grow.

Run Monkey test time, execute:

adb shell  dumpsys meminfo "Packgename"  

This command will play the current application memory consumption, as follows:

* * Meminfo in PID 26390 [Packgemane] * *PSS Private Private swapped heap heap total Dirty clean Dirty Size Alloc Free------   ------   ------   ------   ------   ------   ------Native Heap0 0 0 0 24372 23593 758Dalvik Heap30256 30020 0 0 39116 34608 4508Dalvik Other2254 2180 0 0Stack132 132 0 0Cursor8 8 0 0Other Dev4 0 4 0.

From the log can be seen coresansm25extralight this font has been loaded several times, causing memory leaks.

Like and solve font memory leaks? The method is simple:

Defines a font as a constant and is initialized only in the OnCreate method.

Consts.tf_coresans_font  =  typeface.createfromasset (getassets (), Consts.coresans_font_path);
