I can delete data from the application information, you want to permanently delete the data when the application was terminated. However, the data can not be removed completely. Do you know what the problem is from this source?
Context context = getBaseContext();
WebView webview = new WebView(context);
deleteCacheDir(this);
clearApplicationCache(null);
CookieManager.getInstance().removeAllCookie();
String[] fileList = this.fileList();
for(String file: fileList) {
this.deleteFile(file);
}
WebViewDatabase.getInstance(this).clearUsernamePassword();
WebViewDatabase.getInstance(this).clearHttpAuthUsernamePassword();
webview.clearSslPreferences();
webview.clearView();
webview.clearFormData();
webview.clearHistory();
webview.clearCache(true);
webview.clearMatches();
context.deleteDatabase("/data/data/android.Packege/databaseswebview.db"
context.deleteDatabase("/data/data/android.Packege/databases/webviewCache.db");
webview.freeMemory();
android.os.Process.killProcess(android.os.Process.myPid());
return true;
}
return true;
}
private void clearApplicationCache(java.io.File dir){
if(dir==null)
dir = getCacheDir();
else;
if(dir==null)
return;
else;
java.io.File[] children = dir.listFiles();
try{
for(int i=0;i<children.length;i++)
if(children[i].isDirectory())
clearApplicationCache(children[i]);
else children[i].delete();
}
catch(Exception e){}
}
void deleteCacheDir(Context context) {
Runtime localRuntime = Runtime.getRuntime();
String cachePath = context.getCacheDir().getPath();
String cmd = "rm -R " + cachePath;
try {
localRuntime.exec(cmd);
} catch (IOException e) {
e.printStackTrace();
}
}
