* @Describe 单例 Bitmap 缓存工具类(Java 7 兼容)- 极致强制缓存版
|
||||
* 功能:内存缓存 Bitmap,支持路径关联缓存、全局获取、缓存清空、SP 持久化最后缓存路径、构造时预加载
|
||||
* 特点:1. 单例模式 2. 压缩加载避免OOM 3. 路径-Bitmap 映射 4. 线程安全 5. SP 持久化最后缓存路径 6. 构造时预加载
|
||||
* 特点:1. 单例模式 2. 硬引用唯一缓存(极致强制保持,任何情况不自动回收) 3. 路径-Bitmap 映射 4. 线程安全
|
||||
* 5. SP 持久化最后缓存路径 6. 构造时预加载 7. 引用计数防误回收 8. 高压缩比减少OOM风险
|
||||
* 核心策略:无论内存如何紧张,强制保持已缓存的Bitmap,通过高压缩比降低单张Bitmap内存占用,永不自动清理
