缓存目录不存在 [英] Cache directory doesn't exist
问题描述
怎么可能是 context.getApplicationContext（）。getCacheDir（）返回空？据我所知内部缓存目录应该一直存在。
how is it possible that context.getApplicationContext().getCacheDir() returns null? As far as I know the internal cache directory should always exist.
谢谢！
推荐答案
也许是因为你没有足够的内部存储返回null？尝试同时使用 getExternalCacheDir
maybe it returns null since you don't have enough internal storage? try to also use getExternalCacheDir
另外，如果它不工作，只需访问路径。
also , if it doesn't work , simply go to the path.
标准是，它应该给你的路径/数据/数据/ YOUR_APP_PACKAGE_NAME /缓存/，如果你想在外部存储高速缓存，它应该给你的路EXTERNAL_STORAGE_PATH /安卓/数据/ YOUR_APP_PACKAGE_NAME /缓存/。
the standard is that it should give you the path "/data/data/YOUR_APP_PACKAGE_NAME/cache/" , and if you want the external storage cache , it should give you the path "EXTERNAL_STORAGE_PATH/Android/data/YOUR_APP_PACKAGE_NAME/cache/" .
