1.删除保存于手机上的缓存//clearthecachebeforetimenumDays
privateintclearCacheFolder(Filedir,longnumDays){
intdeletedFiles=0;
if(dir!=null&&dir.isDirectory()){
try{
for(Filechild:dir.listFiles()){
if(child.isDirectory()){
deletedFiles+=clearCacheFolder(child,numDays);
}
if(child.lastModified()
if(child.delete()){
deletedFiles++;
}
}
}
}catch(Exceptione){
e.printStackTrace();
}
}
returndeletedFiles;
}
activity中的代码：webView.clearCache(true);
clearCacheFolder(getApplicationContext().getCacheDir(),
System.currentTimeMillis());
getApplicationContext().deleteDatabase("webview.db");
getApplicationContext().deleteDatabase("webviewCache.db");
clearCacheFolder(getApplicationContext().getCacheDir(),
System.currentTimeMillis());
getApplicationContext().deleteDatabase("webview.db");
getApplicationContext().deleteDatabase("webviewCache.db");
2.打开关闭使用缓存
//优先使用缓存：
WebView.getSettings().setCacheMode(WebSettings.LOAD_CACHE_ELSE_NETWORK);
//不使用缓存：
WebView.getSettings().setCacheMode(WebSettings.LOAD_NO_CACHE);
3.在退出应用的时候加上如下代码Filefile=CacheManager.getCacheFileBaseDir();
if(file!=null&&file.exists()&&file.isDirectory()){
for(Fileitem:file.listFiles()){
item.delete();
}
file.delete();
}
context.deleteDatabase("webview.db");
context.deleteDatabase("webviewCache.db");
