When my application goes to background , my (static and singleton) objects are cleared. So I tried to store these objects in Applicaton Context . I am using the following code.
Accounts.create(getApplicationContext()) will be called once to store the accounts instance.
Is that possible(reliable) to store objects in Application Context ? I am not sure the following way is correct or not . please guide ..
public class Init extends Application {
private Hashtable<Object, Object> globalStore = new Hashtable<Object, Object>();
public void putToGlobalStore(Object key, Object value) {
globalStore.put(key, value);
}
public Object takeFromGlobalStore(Object key) {
return this.globalStore.get(key);
}
public void removeFromGlobalStore(Object key) {
this.globalStore.remove(key);
}
public boolean containsInGlobalStore(Object key) {
return this.globalStore.containsKey(key);
}
}
public class Accounts {
protected Accounts(String name, Context context) {
Init init = (Init) applicationContext;
init.putToGlobalStore(name, this);
}
private static Init applicationContext;
public static void create(Context context) {
if (context instanceof Application)
applicationContext = (Init) context;
else
applicationContext = (Init) context.getApplicationContext();
if (applicationContext.containsInGlobalStore(GLOBAL_NAME))
Logger.log("Warning " + GLOBAL_NAME
+ " is already created. This will remove all old datas");
new Accounts(GLOBAL_NAME, applicationContext);
}
private static final String GLOBAL_NAME = "accounts";
public static Accounts getInstance() {
try {
return (Accounts) applicationContext
.takeFromGlobalStore(GLOBAL_NAME);
} catch (Exception e) {
Logger.log("GLOBAL_NAME Lost");
return null;
}
}
Please help.
