Android : Put All Code Relating To Creating Time - Date Dialogs Setting Values
Sep 24, 2010
I'm currently learning android and java, and I am having some issues with importing a java file.
I am working with the time and date example in the android api demos, and I want to put all the code relating to creating the time and date dialogs setting the values etc into a separate java file, and in my main java file run when the application starts, just declare the buttons and onclick events.
What is the best way to do this? Do I need to put all the code inside a class(that extends activity) or method? How do I use this inside my main class. Code...

I wanted to know whether we can implement both date and time picker in one view...
In iphone app you can pick both date and time through one view. But in android we have date picker and time picker seperately. So, is there any method by which i can get values of both date and time from one view?

I have read about using a 'dip' scale rather than just px, this is straightforward to implement in XML. But how do I adjust values accordingly in the java code? For example:
tv.setTextSize(20)
will result in text of size 20 px right? What's the quickest way of making this 20 dip, other than adding a resource?

I'd like to set the ringer mode to silent for specific events in the future. It should only happen if a checkbox in the preferences is checked. I know that I have to update the manifest for the permissions and also that I can set the ringer mode with something like this:
if (getPreferences(MODE_PRIVATE).getBoolean(PREFS_KEY_SILENTOPTION, false)) {
AudioManager audioManager = (AudioManager) getSystemService(AUDIO_SERVICE);
audioManager.setRingerMode(AudioManager.RINGER_MODE_SILENT);
}
But how can I set (and reset) it for a space of time in the future?

Basic but frustrating issue with my Droid X - the time stamp for the pictures that I take are way off - the date is actually right, but the time is something like 7 hours too fast.My phone's date and time is set correctly, of course (it does so automatically) - for some reason though, the camera's date stamp is wrong and I can't figure out how to adjust it. Any idea how I can fix the date and time for the camera?

Under Settings -> Date and Time, whenever I set a Date to a future or past number, it gets overridden by the Network/WiFi. I've made sure that I've unchecked the Automatic option. Anyone have any ideas why this is?
When I turn off my Network(3G) and WiFi, I'm able to set the Date to whatever I want without it getting reset like 2 seconds later.

Does anyone have a code example of how I can time bomb an Android application so It will not work after a given date?
I would like to release a "beta" application for testing but would like to make sure it will only work while I have the application officially in beta.

I do not know the reason why am i getting same values of different JSON date values. Here is my code for parsing date values in JSON date format:
package com.jsondate.parsing;
import java.text.SimpleDateFormat; import java.util.Date;
import android.app.Activity; import android.os.Bundle; import android.util.Log; import android.widget.TextView;
public class JSONDateParsing extends Activity {/** Called when the activity is first created. */String myString;
@Override public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
TextView tv = new TextView(this);
//Date d = (new Date(1266029455L));
//Date d = (new Date(1266312467L));
Date d = (new Date(1266036226L));
//String s = d.getDate() + "-" + d.getMonth() + "-" + d.getYear() + d.getHours() +
d.getMinutes() + d.getSeconds();
// SimpleDateFormat sdf=new SimpleDateFormat("yyyy MMM dd @ hh:mm aa"); //Toast.makeText(this, d.toString(), Toast.LENGTH_SHORT);
Log.e("Value:", d.toString());
myString = d.toString();
String []words = myString.split(" ");
for(int i = 0;i < words.length; i++)
Log.e("Value:", words[i]);
myString = words[2] + "-" + words[1] + "-" + words[5] + " " + words[3];
tv.setText(myString);
setContentView(tv);
} }

Is there any android widget that enable to pick the date and the time at the same time ? I already use the basic date picker and date picker:
http://developer.android.com/guide/tutorials/views/hello-timepicker.html
http://developer.android.com/guide/tutorials/views/hello-datepicker.html
but they are not that sexy and user friendly (I found). Do you know if a widget including both date and time exists? Thanks a lot,WW.

Does anyone know any workarounds of this?

I recently received an LG optimus f3 with android 4.1.2.
After activating the phone, it displayed the correct date and time for my time zone, so I didn't mess around with settings to reset the time, as I would with any other device.
However, I've noticed that the time changes to exactly an hour ahead, before changing itself back several minutes later.
I went to settings > date and time, but 24 hour time and selecting a date format are the only options listed.
I prefer to leave mobile data off when I am at home and can use the wi-fi. Is it necessary to have mobile data turned on, so the phone can receive the time from a cell tower, or is there a way I can set an internal clock?

In the method "OnCreate" of my actvity, I'm displaying a little progress dialog while loading data. It's done every time the "OnCreate" method is called so even when the screen orientation change. In the nominal case, there is no problem even if the user change the screen orientation.
But, if the user opens another dialog (used to select an item in a list), then change the orientation, the progress dialog is displayed behind the "list" dialog and is not impacted by the "removeDialog". Do you have any clues on that behavior?

So I've just published my first paid app to the Market and I used the new LVL with the default ServerManagedPolicy. On working through the docs and getting it set up I noted the references to the server response extras VT, GT, GR & UT, and the impression I got from quotes such as "a typical value would be 5 or more days.", "a typical value would be "10" or higher." etc., was that we would have some way of setting these server response values per app when we upload them to the Market. Either I'm missing something, or there does not seem to be a way to set these in the Developer Console that I can see? If we can't set these, it's not really a 'managed' policy at all, but a random 'whatever the server decides to respond with' policy, particularly given the vagueness of the documentation.
I really hate phone home licensing, and am only using it because it seems to be the only option to combat Android piracy. Ideally I want to just check once when the app is first launched, once a day or two later to check they didn't return it, then cache that for 6 months (forever?) to minimize disruption to my users. Is this kind of thing possible with the ServerManagedPolicy or do I have the wrong end of the stick about the 'management' features and have to roll my own? On a side note, if I can't buy my own app, how can I test my licensing is working in the wild? I got several 'NOT_LICENSED' responses in testing even when I set it to return 'LICENSED' in the console, so I'm not 100% convinced of its stability and want to actually see how well it works outside the testing environment, but apparently can't buy my own app to do so!

I defined a white color in mycolors.xml under res/values as below:
<?xml version="1.0" encoding="utf-8"?>
<resources>
<color name="my_white">#ffffffff</color>
</resources>
In my code, I set the text color of a TextView as the white color I defined:
TextView myText = (TextView) findViewById(R.id.my_text);
myText.setTextColor(R.color.my_white);
But the text in the TextView turned out to be a black color. When I use @color/my_white in layout xml files, it works fine. I check the generate R.java, and see: public static final int my_white=0x7f070025;

Newbie here. I am very serious about getting the new Spring hero. As an airline pilot traveling outside the US I have a question as to the GPS function. When I turn on the phone in another country to use the GPS function how do I update the date and time and approx location so the gps knows what sats to look for? If I don't have phone/network coverage, and I probably won't how will or update?

I don't know where to put the bug report of APIs.
I use WebView to display some pages in my dictionary software. I met some problems with WebView.
1) could not handle the color values When I use the HTML code: <font color="#00FF00"></font> the WebView could not handle this type of tags. But <font color="red"></font> can work well.
This bug exist both in SDK1.0 & SDK1.1
2) Chinese Char: I use UTF-8 as the charset, and if there exist some Chinese chars, then this HTML code could not be displayed in WebView: <html><head><meta http-equiv="Content-Type" content="text/html; charset=UTF-8"></head> <body> <p><font color="red">[-------- 美国 统词典[双解] --------]</font></p> </body> </html>
This bug exists in SDK1.1.

I have a strange problem when parsing a ISO8601 date and time with SimpleDateFormat.
The relevant code is:
CODE:........
For input I'm giving it a string
2010-09-06T15:30:00+02:00
And as a return I get a Date object with date set to 6th of January 2010 with time of 13:30 and timezone of GMT+00:00.
I also tried using "2010-09-06T15:30:00+0200" with same results.
Confusing thing is, that the date set is partially correct, just the month is set wrongly.
The issue is shown on Android 1.6 and Android 2.2.

By any means, programmatically can I get the install date & time of the already installed apps on the android device. The ApplicationInfo doesn't provide this info. While digging through the /data folder through the DDMS perspective, I saw the installed apk's do contains the Date & time of when it was installed, but the sad part is that this /data folder is not accessible on the device programmatically.
