My book reference is based upon that comment. Moreover, making any file MODE_WORLD_READABLE or (worse) MODE_WORLD_WRITEABLE is a bad idea. You lose any hope of security. If you wish to share data between two applications, there are a myriad of solutions, such as: service with an API exposed by AIDL service with an API exposed … Read more
Add the below to your manifest: <activity android:name=”.AppPreferenceActivity” android:label=”@string/app_name”> <intent-filter> <action android:name=”com.scytec.datamobile.vd.gui.android.AppPreferenceActivity” /> <category android:name=”android.intent.category.DEFAULT” /> </intent-filter> </activity>
Unfortunately most of the answers you got here are wrong … at least slightly. In the sense that the symptom is being treated, not the cause. Let’s recap. Java Preferences has two “trees”: the user tree and the system tree. You can write your own backend to Java Preferences (called a backing store) but few … Read more
there are many ways, but here’s a simple, easy to understand way. add these lines to your ~/.vimrc: autocmd FileType html setlocal ts=2 sts=2 sw=2 autocmd FileType ruby setlocal ts=2 sts=2 sw=2 autocmd FileType javascript setlocal ts=4 sts=4 sw=4
You could of course export/import those settings. The other approach is to enable project specific settings for some settings. We have a very small Git repository with those kind of files: .settings/org.eclipse.jdt.core.prefs (compiler problem settings and formatter rules) .settings/org.eclipse.jdt.ui.pref (cleanup rules, common code templates) The common settings are just copied/merged in each projects .settings directory, … Read more
In this case, the obvious solution, java.util.prefs.Preferences, is probably the correct one. RCPrefs from this game is a simple example that demonstrates saving a variety of data types, including enum. The exact implementation is highly dependent on the application. While tedious, it needn’t be especially complex. For expedience, the example uses static methods; frame and … Read more
Here it’s how I made it for my app. In a few words – in Activity.onCreate() you get resource id of style with specific set of font sizes and apply this style to theme of activity. Then with preferences activity you can switch between these sets. First of all in values/attrs.xml declare attributes for set … Read more
You may want to look into using PersistenceService, a feature of Java Web Start that “provides methods for storing data locally on the client system, even for applications that are running in the restricted execution environment.” Related examples may be found here and here.
this question is similar to mine: initialize-preferences-from-xml-in-main-activity Just use this code in onCreate method: PreferenceManager.setDefaultValues(this, R.xml.preference, false); It will load your preferences from XML, and last parameter (readAgain) will guarantee that user preferences won’t be overwritten. That means setting the readAgain argument to false means this will only set the default values if this method … Read more
Spent all day looking for the answer, only to find it 10 minutes after asking the question… Came across a solution through Key-Value-Observing: [[NSUserDefaultsController sharedUserDefaultsController] addObserver:self forKeyPath:@”values.MyPreference” options:NSKeyValueObservingOptionNew context:NULL]; Or, more simply (per comment below): [[NSUserDefaults standardUserDefaults] addObserver:self forKeyPath:@”MyPreference” options:NSKeyValueObservingOptionNew context:NULL];
