Clear Cache in Android Application programmatically
android
Solution
If you are looking for delete cache of your own application then simply delete your cache directory and its all done !
public static void deleteCache(Context context) {
try {
File dir = context.getCacheDir();
deleteDir(dir);
} catch (Exception e) { e.printStackTrace();}
}
public static boolean deleteDir(File dir) {
if (dir != null && dir.isDirectory()) {
String[] children = dir.list();
for (int i = 0; i < children.length; i++) {
boolean success = deleteDir(new File(dir, children[i]));
if (!success) {
return false;
}
}
return dir.delete();
} else if(dir!= null && dir.isFile()) {
return dir.delete();
} else {
return false;
}
}
Problem
what is the correct way to clear cache in android Application programmatically. I already using following code but its not look work for me ``` @Override protected void onDestroy() { // TODO Auto-generated method stub super.onDestroy(); clearApplicationData(); } public void clearApplicationData() { File cache = getCacheDir(); File appDir = new File(cache.getParent()); if (appDir.exists()) { String[] children = appDir.list(); for (String s : children) { if (!s.equals("lib")) { deleteDir(new File(appDir, s)); Log.i("EEEEEERRRRRRROOOOOOORRRR", "**************** File /data/data/APP_PACKAGE/" + s + " DELETED *******************"); } } } } public static boolean deleteDir(File dir) { if (dir != null && dir.isDirectory()) { String[] children = dir.list(); for (int i = 0; i < children.length; i++) { boolean success = deleteDir(new File(dir, children[i])); if (!success) { return false; } } } return dir.delete(); } ```
