Glide缓存Simple

1. 缓存路径的指定
2. 缓存大小的获取
3. 磁盘缓存清除(两种方法)

4. 内存缓存清除

   • 可clone之后查看使用Simple

Glide cache Simple.

1. The cache path specified
2. The cache size
3. The disk cache (two ways)

4. Memory cache to clearMay

   • use Simple clone after check

获取Glide磁盘缓存大小

public String getCacheSize() {    try {        return getFormatSize(getFolderSize(new File(Application.getInstance().getCacheDir() + "/" + GlideCatchConfig.GLIDE_CARCH_DIR)));    } catch (Exception e) {        e.printStackTrace();        return "获取失败";    }}

清除Glide磁盘缓存

public boolean cleanCatchDisk() {    return deleteFolderFile(Application.getInstance().getCacheDir() + "/" + GlideCatchConfig.GLIDE_CARCH_DIR, true);}public boolean clearCacheDiskSelf() {    try {        if (Looper.myLooper() == Looper.getMainLooper()) {            new Thread(new Runnable() {                @Override                public void run() {                    Glide.get(Application.getInstance()).clearDiskCache();                }            }).start();        } else {            Glide.get(Application.getInstance()).clearDiskCache();        }        return true;    } catch (Exception e) {        e.printStackTrace();        return false;    }}
