Android :: Accessing Fields Across Package
Jul 6, 2010How do I make fields accessible across a package? Currently, even if they are declared public i'm not able to access the fields from another class in the same package.

Android :: Can't Access Package Private Fields In Android.widget Package?
Oct 7, 2010I'm attempting to override an Android View class to tweak the functionality just slightly. But I need to modify a field that does not have a setter method. I've placed the subclass in a package called android.widget. Why can't I access any of the package-private member fields? I notice that the compiler says they "cannot be resolved," rather than not being accessible. Does this have something to do with how Android.jar is built?

Feb 12, 2009i work on custom Application Manager and try to get the disk usage of installed package. So PackageManager.getpackageSizeInfo was removed from SDK on 0.9->1.0 update android.content.pm. PackageStats(String pkgName)(cacheSize, codeSize, dataSize) returns always "0" Size of phys. file (java.io.File) in "/data/app" seems wrong/not completely. Has anybody any solution to get the total disc space used by an installed package?

Jun 9, 2010Alright, I'm a little new to the Android SDK, so forgive me if my question doesn't make sense or is very trivial. I'd like to add a custom field for contacts, that contains the contacts username on a website I'm doing this app for. And, with this custom field, I'd like to have the ability to click it (like "Send message" or "Call mobile") so that I can go to a specif Activity in my application, with a TextView set with the username that I just clicked on.Sorry if that is a bit confusing, if you need anything else let me know!

When a user clicks a specific button, I want a customized "prompt" box to appear, containing several fields (a textfield, a password field, and a checkbox field). I would also be nice if I could add an image inside this box. How would I go about implementing this sort of functionality?

Feb 3, 2010I would like to use EditTextPreference to show 2 input fields instead of 1. For instance, a username and password field should be shown. I don't want to use a dialog for each one. How can this be done? In the WiFi settings there is one that does this, when you want connect to a protected network, a dialog shows to set a password for the credential storage with 2 fields.
View 1 Replies View RelatedAndroid :: Combining Subclasses Which Have Different Fields For Efficiency?
Feb 7, 2010I'm working on a Java Android game. Games here generally need to use memory pools to avoid garbage collection.Making use of subclasses is a pain when using memory pools as you need to e.g. say how many Roamer and Chaser objects you want upfront and not just how many Enemy objects you might need.I would then have an update function that checked the "type" variable and updated accordingly. This is obviously a more C-like approach. It feels hacky though because e.g. a roamer enemy will have a "target" variable it never uses. I'm unlikely to have more than a 100 enemies in memory at a time though so it really isn't a big deal memory wise. I just want some compromise between nice code and speed.Does anyone have any comments on how best to structure this? Is merging classes like this going too far? Is this ever a good idea? Should I just use a regular class tree?

View 5 Replies View RelatedAndroid :: Private Fields Naming Guidelines
Jan 25, 2010Here http://source.android.com/submit-patches/code-style-guide#shortmethods it is stated that :
"Field Names
* Non-public, non-static field names start with m.
* Static field names start with s.
* Other fields start with a lower case letter.
* Public static final fields (constants) are ALL_CAPS_WITH_UNDERSCORES.
also states that : "The rules below are not guidelines or recommendations, but strict rules. You may not disregard the rules we list below except as approved on a need-to-use basis." I don't like the "m" convention before private or package fields in a class... I really find this uninspired. I mean, if we try to apply good designs, the low coupling of the classes implies having few public fields. actually, in my programs I usually have no public fields, even when I need some I use getters and seters. so, why should I be forced to have almost all my fields in the program with an "m" in front of them? wouldn't be easier to have the few public fields, if there are any, with some "g" in front or something? or just use setters and geters as beans suggest? this really makes my code harder to read. also, following these guidelines, local temp variables used in the methods have no restriction so they could easily be mistaken for public global fields (also without restriction). this also I find to be wrong, as it is a probable source of mistakes. I understand to have a way of differentiating from fields, but private/protected member fields are the most used in an application, they shouldn't be less "readable". what do you think? should I follow the guidelines?

Android :: Input Fields / Converting Text To Numeric
Nov 4, 2010I have an app I am working on that does some math on a few variables and outputs the answer. Well that's the plan anyway. Being a total n00b at Android & Java I am not sure of a couple of things.1) I have created text fields in the layout file for user to enter values. Instead of text fields should I use numerical value fields, if such a thing exists? 2) How can you convert from a text field to a numerical value and back again?

View 4 Replies View RelatedAndroid :: How To Implement Custom View With Variable Fields?
Jul 7, 2010I have a ListView that displays a set of notes, each with varying ammounts of data (i.e. some have a due date, others don't).Currently, each view in the list is a RelativeLayout containing a TextView for each field, plus two Button and a CheckBox. I then simply hide the unused fields by setting visible false on each one.This has worked well, but I'm about to add a lot more data fields to the notes and inflating that many unneeded views for each row will surely kill my app. I need a more dynamic solution.I've decided the best way to go is to create a custom view. How can I implement/design my view so that it can display a variable number of text fields without creating/ destroying textviews each time (which would be quite expensive and worse than my current situation), or maintaining a large pool of hidden textviews?

It does not compile on 2.1. The static fields DIRECTORY_PICTURES, DIRECTORY_MUSIC etc. Don't seem to be found. Using the filter api checkbox, I see that it was removed in Android 2.2 (or api version 8). So the manifest file needs to contain minSdk defined as 7.

View 2 Replies View RelatedGeneral :: Where Are User Defined Fields In Android Contacts
Apr 29, 2012Have been a long time user of Outlook and Blackberry and store a lot of information in the User Defined Fields. Those fields seem to have been eliminated from all of the Android Contact Apps. I don't see them in Motorola Corporate Sync, Touch Down or Moxier Mail. Am I missing something, can't believe the developers of Android apps would just skip those fields. Any App that I can store and sync those fields. Google Contacts has the fields. I have just upgraded from a Blackberry Bold to a Verizon Droid Maxx. Love the big screen on the phone, struggling with the touch keyboard and really struggling with losing half of my contact information.

View 2 Replies View RelatedMotorola Droid :: Android Browser - Date And Time Fields
Nov 8, 2009I love my new Droid, but if I can't use it for work, I can't use it period. Anyway, here is the problem. I have a website which interfaces with the main dispatch server at Fujitsu Transaction Solutions. I wanted a phone that would let me go to that website and post dates and times for jobs to which I have been dispatched. Unfortunately, on the Android browser, the date and time fields are each 1 space short of being able to hold dates and times, i.e. the time fields are 3 spaces, but I need to put in, say, 1800 for 6 pm. Follow? It is hard to explain.
There is what I think is a Java applet that lets you select a date by clicking on a little calendar icon. I am sure you have seen these on travel websites. This icon does not show up on the Android browser. I checked the Android browser's Java compatibility, and it passed. I tried the 1nternet and Opera browsers, as well. 1nternet has the same issue, and Opera apparently does not work with Android 2.0, yet. I couldn't go to any typed-in URL with Opera.
Android :: Do Null SQLite Data Fields Take Up Extra Memory?
May 9, 2010I'm using the built in sqlite library on the Android platform.
I'm considering adding several general purpose fields that users will be able to use for their own custom applications, but these fields will be blank most of the time.
My question is, how much overhead will these blank fields add to my database? Do null fields even take up per record memory in sqlite? If so, how much? I don't quite understand the inner workings of a sqlite database.
