i want to clear data cache programmatic of my application that is increasing, right now i am clearing from Settings->Applications->Manage Application->My Application->Clear Cache.
but i want to do it by programmatic, please help me.
When you calling this class, it`ll calculate all installed application cache files and then simply delete it from your phone, which are not affected to database or your personal data. it will boost your phone and make it faster, cache file is removed
public class MyApplicationClass extends Application {
private static MyApplicationClass instance;
@Override
public void onCreate()
{
super.onCreate();
instance = this;
}
public static MyApplication getInstance() {
return instance;
}
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("TAG", "**************** 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();
}
}
Just a guess:
Delete these files by knowing their absolute path to cache directory - getCacheDir() - http://d.android.com/reference/android/content/Context.html#getCacheDir().
