[android-developers] Shared Preferences
Hi, what is the difference betweent PreferenceManager.getDefaultSharedPreferences and getSahredPreferences(String name, int mode) ? I thought that the defaultSharedPreferences are someting like global preferences that every application can manipulate. So lets say that I can call a preference from another application in my own application, and even change it. And the getSharedPreferences are preferences that I can only use in my application. Thats just what I thougt it is...but I'm not sure. -- You received this message because you are subscribed to the Google Groups "Android Developers" group.

In activity A put your value in the shared preference:
SharedPreferences prefs =
PreferenceManager.getDefaultSharedPreferences(context);
Editor editor = prefs.edit();
editor.putString("key", "value");
editor.commit();
to get the value from shared preference in activity B:
SharedPreferences sharedPrefs =
PreferenceManager.getDefaultSharedPreferences(context);
String value = sharedPrefs.getString("key", null);

Re: [android-developers] Android memory allocation and static variables
Ok...the problem is that if I unregister from GCM the app will still receive notifications until GCM sets it to unregistered that can wait for 2-3 days. Thats what i heard at least... The only way I see here is to write it to a file if its registered or not, and when the push comes check in the file if it is registered. You have any other suggestions?

[android-developers] Android memory allocation and static variables
Hi everyone, I am writing on an Android application where i am registering to GCM. When I click the cehckbox to register i want to set a static variable isRegistered to true/false. Now when i receive the message I want to check this variable and if it is true I make an notification. So when i get out of my app I still receive the notification and everything is good. But what happens when Android deletes my application from memory to free memoy? Does my static variable still exist? -- You received this message because you are subscribed to the Google Groups "Android Developers" group.

[android-developers] Tokens
Hi, I'm not really familiar with tokens in general. I searched and couldnt find any definitions nor explanations. So what are tokens exactly, and how do you create them, and for what are they? Im trying to make an app where i will send my Android device token to a notification push server. The server later pushes some notifications to the user with the device token. How do i get this token? -- You received this message because you are subscribed to the Google Groups "Android Developers" group.

[android-developers] Tokens
Hi, I have to make an app where i send my device token to a server. The server is a Push server that will push notifications to the mobile device later. My question is; What are tokens and how do you create them? Does the server create my token or who? I know that for the Facebook API Facebook makes the token for you. So does every token creation work like that? -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
