I play a video so that it stores a lot of data. I can’t delete the cache in xperia mini, it works fine in other phones.
I tried
mWebview.clearCache(true);
and
File cacheDir = this.getCacheDir(); File[] files = cacheDir.listFiles(); if (files != null) { for (File file : files) file.delete(); }
But there is always an error in log-cat:
