I am creating an application which connects to the server using username/password and I would like to enable the option "Save password" so the user wouldn't have to type the password each time the application starts. I was trying to do it with Shared Preferences but am not sure if this is the best solution. I would appreciate any suggestion on how to store user values/settings in Android application.

I have added a mute button to a menu on my application and am wondering if it is possible to store the user's latest preference of either muted or unmuted for use when he/she reopens the application. Here is the code I am using for setting mute or umute:
public void isMute() {
if(mIsMute){
mAm.setStreamMute(AudioManager.STREAM_MUSIC, false);
mIsMute = false;
}else{
mAm.setStreamMute(AudioManager.STREAM_MUSIC, true);
mIsMute = true;
}
}
when you got your phone set up JUST perfect, then blam-o something happens and you have to do a factory wipe of your phone, eliminating all your perfectly placed settings. wouldn't it be nice if there was an app that you could run to STORE all your settings, on your sd card, then if/when you have to do a wipe, OR get a new phone (of the same model) you can run this app and bingo bango, all your settings are just how they were before?
View 7 Replies View RelatedI am developing an Android frontend to a web application using its API. This Android application will expose some extra features if the user is a 'pro'. Therefore I need the Android app to acquire the information whether an account is pro. That is done while getting the token. In other words, when the Android application requests a token to the web application via the API, the web application provides also a flag representing whether the user is a pro.
When the Android app gets that piece of information, it stores it in the SharedPreferences, like this: this.sharedPreferencesEditor.putBoolean(Account.PRO_ACCOUNT, isPro).commit();
Then the Android app reads that value to decide whether a certain feature is available to that user. Now, my question is: is that approach easily hackable? I mean, can some clever user work-around this system and get pro-features even if they are not pro-users? How could do that?
I'm writing an application wherein users will sometimes make orders through it. I want to give users the option to save their billing info (name, address, etc.) so that it can be quickly restored later if they want to make another order. The user will enter a password to secure the data. Obviously I can't just put this as a file on the device, as anyone can root/find the data. Is there a built-in Android method for storing secure data that is locked with a password? If not, what is a good place to start for storing this data securely using Java?
View 2 Replies View RelatedI am working on an app that connects to a media providing site and downloads mp3 files to the user phone. I would like for the user to be unable to copy these files off the phone but only listen to them through my app. I am currently trying to encrypt the files using DES and encryption and decrypt and play the file in bits in the app. This is however not working. Is there a better way of achieving my end goal or has anyone else implemented a similar solution?

View 1 Replies View RelatedI'm trying to write an app that consists of an activity that manages a background service. However, I want to implement a user setting for automatically starting the service up at boot time. I have user settings implemented with SharedPreferences and I have the services starting up at boot by using a BroadcastReceiver and listening for BOOT_COMPLETED. However, I can't figure out a good way to implement a setting so that the service is only started at boot if said setting is enabled. I can think of a few cheap ways to do this (such as messing with onCreate() in the service, or creating/checking for a file on SD card) but I want to follow good practice. There must be a good way to do this because there's tons of apps out there that do it, I just can't find anything online about how to do it.

View 1 Replies View RelatedI want to create a global variable store for a list of user defined objects. I have a LinkedList of Feed (a user defined object) that I need to be made available to a new Activity that is created. This list is displayed using a ListView and so when an item of the ListView is clicked, I need the correct Feed index to be 'passed' to the new Activity. I have no problem doing this as I create an Intent and then pass the id of the selected row. I need the new Activity to have access to the LinkedList of Feed objects.
There are different ways to do this (explained here - http://code.google.com/android/kb/framework.html). I want to use the option (quoted from link above): The android.app.Application class The android.app.Application is a base class for those who need to maintain global application state. It can be accessed via getApplication() from any Activity or Service. It has a couple of life- cycle methods and will be instantiated by Android automatically if your register it in AndroidManifest.xml.
I want to use the above method as I could then fill the LinkedList at application start and then use it throughout without any duplicates etc. Does anyone know how the android.app.Application class can be used as a global variable store that can be accessed from other classes? I cannot find any more information on this method of passing information between Activities within a single application. Any information regarding passing user defined objects would be useful and specifically how to get the above idea to work.

I've created an application which uses around 15 small audio files. Right now I'm using mp3 files and each is around 200KB. These files are stored in my res/raw directory. I'm using SoundPool class to play the files in my application. I'm hoping to put this application on the android market place. Can one of you suggest what is the best way to store so many audio files? Will my application be scalable? Is wav or ogg format better approach instead of mp3? Please let me know.
