I am building an app that will be an Android listview. Each listview object will be a title and a few sub-categories and ratings. I would like the user to be able to sort the listview by these ratings or sub-categories.

I cannot get the data from SqLite using order by because the data is encrypted, so the sort wouldn't work there. Is it possible to sort the items in the ListView?
View 5 Replies View RelatedI have been using the Android documentation for a few days now, and it is quite good and easy to read. Apart from that I noticed that I missed something, and now I found out what it is: Examples and comments.
If you look at the PHP documentation (e.g. http://www.php.net/manual/en/function.substr.php for the PHP substr() function) you will see many syntax-highlighted examples and comments by users.
Of course there are examples in the Android documentation, especially in the Dev Guide category - they just are not at the right place if one searches the reference for a specific method or functionality. What do you think about this?

View 1 Replies View RelatedI'm a bit scared about obfuscating my application completely. I'm afraid to run into issues where I can't figure out a bug because lines and function names wont match. Please correct me if I'm wrong... I thought maybe the simplest way to protect important parts of my code is to create a jar of the important files. I know and understand that jars are good only for classes and no xmls or other Android dependent parts. I believe it would be simple this way since I would not have to worry about obfuscating too much and breaking my project. Also, could be helpful for distributing to clients a library which they can't decompile.
In terms of obfuscating jars maybe I could do the same to the Market Licensing code to protect my paid application from pirating? What are your thoughts on my approach? Maybe bad idea? What experiences have you had with obfuscating your application? Is it not as bad as I think?
Could developer upload 'component'/SDK to android market? Now it seems only have 2 type: 'application' and 'Game'. I just wonder if android market has the mechanism for developers to upload component-wise programs which can be used in others's application. Then developers may get benefit from earch others. Or Is android provide a easy way to invok and communicate with other application from one application?
View 4 Replies View RelatedIn an app with a small number of POJOs and lots of helper methods that operate on them, what's better performance-wise: to make the helper classes singletons or to make the methods static?
View 4 Replies View RelatedRather than do this by just creating a lot of strings (which I've already managed), I want to add an integer and then print those list to the screen. At the moment, I'm just trying to get one integer on the screen without even adding it, but the app is "force closed" in the emulator. Why doesn't this work? Add one to it and then print the answer to this for a given loop (say up until 10).
Code:
package com.monkeez.count;
import android.app.Activity;
import android.os.Bundle;
import android.app.Activity;
import android.view.View;
import android.widget.TextView;
public class Count extends Activity {
/** Called when the activity is first created. */
TextView countDisplay;
@Override public void onCreate (Bundle savedInstanceState) { int counter = 1;
countDisplay = new TextView(this);
this.setContentView(countDisplay);
countDisplay.setText("counter here");
} }
The log cat is thus:

With this, I could easily tell what I have for the whole month. The Hero's built-in calendar only shows gray triangles when there are events available. Is there any third party app I can use? The app must fulfill these two conditions:
1) Can have category icons on monthly view.
2) Can sync with Outlook.
I've recently bought this phone and imported all my contacts from my Gmail address book. Every contact has at least one assigned category, and some have multiple categories. I can filter my contacts on the X10 Mini Pro, which greatly assists in finding people, but I can't see any way to add a category tag to a new contact. I've looked at all the manuals I can find, and don't see this point addressed. Lots of information about adding photos and Timescape, but nothing useful.

View 2 Replies View RelatedI am in between phones right now, and no longer have a N1 and am looking to replace it with another Android phone without switching carriers from AT&T.They currently have the HTC Aria(I have no interest in), the Samsung Captivate(Galaxy S), and will soon be getting the X10.This phone has been out for some time in EU/Asia and Canada for a bit, and I am fairly familiar with it. It seems the bad points are no multi-touch ever, Android 1.6 with a who knows for sure on Android 2.x, but the rest seems fairly solid. Most of the reviews are from when it first came out, and generally complain about the GUI being slow.My questions are basically:
1. Is the phone solid hardware wise, with build quality etc? I know it's mostly plastic, but does it feel cheap, hold up well?
2. Has Android 1.6 caused you any problems app wise? I'm fairly certain google navigation works on 1.6, which is a deal breaker for me if it doesn't.
3. How is the GUI, do you enjoy it? I can't stand Samsung's TouchWiz, Moto Blur, and prefer stock Android, but don't mind HTC Sense.
4. I keep reading something about the screen doesn't have all it's colors activated or something? Others say it is amazing. Curious if it is the Super LCD Sony is selling HTC to replace AMOLED.
I know the Galaxy S has a better CPU, GPU(Android isn't much for gaming anyways), more ram, Super AMOLED, blah, blah but their software is terrible and I don't like their form factor.
I just created my own "Home" to replace the stock android one or Sense.
All is working fine and I get all I want. My only problem is to replace to long press on home key ( that usually show the last 6 activities you launched) by my own launcher.
I successfully replace the long press on MENU button with this code:
CODE:..........
and this part part for the long press:
CODE:.............
But the problem is that I wasn't able to replace the KeyEvent.KEYCODE_MENU with KeyEvent.KEYCODE_HOME
Is that something locked in the code that avoid user to use a Home long press?
And once it is released, will you switch to the Supersonic: A.) With a full upgrade from Sprint B.) Buy it outright C.) Stay with your Hero How much effect will a 2.1 Hero update have on your decisions? What will your actions be if it WILL and WILL NOT get the upgrade.
