Android :: Storing Double Values In SQLite / How To Ensure Precision?
Jun 21, 2010i have a problem with double values i need to store in an android homed sqlite database. since these double values represent gps values (lat & lng), i really NEED an absolute precision down to the 9th number after the comma.when reading lng from this table into some (java) double variable, i get a value like "0.999956837" - this renders the values pretty useless to me.is there a way to enforce the precision i need other than storing the values as "text" fields (what would make expensive casts neccessary) or storing them as integers (meaning i need to multiply/divide at each write/read-op)?

Apr 2, 2010I am currently in the process of creating an application that records current location of a mobile device in intervals, displaying the route as a coloured line on the device in real-time. At the same time the application is storing the longitude and latitude in a SQLite database as I want the user to be able to bring up that specific route again.The route has a primary key and each waypoint is linked to that route by a foreign key. What would be the easiest way to display the saved route on the map?

Sep 25, 2010I have a table called "images":
CODE:.........
On inserting a row, I'd like the URL column to be unique. At the same time, I'd like to find out the id of the row with that URL.
INSERT OR IGNORE images (url, caption) VALUES ("http://stackoverflow.com", "A logo"); SELECT last_insert_rowid(); -- returns the id iff there was an insert.
Of course, I'd like to do it as quickly as possible, though my first thought was along the the lines of the following pseudo code:

But this seems hopelessly inefficient.

Apr 6, 2010That's a lot of code... no time to read it over now.. but off the top of my head: look into either using a database, an Application class (that will run the whole time your app is alive), or adding extras to the Intent bundle before starting your subactivity. These are all methods to pass data around between activities.

Nov 17, 2010I have searched and searched and I just can't get this code to work. I have a main.xml layout and a setting.xml. I have some values I would like the Settings.class to change in my main apps class.Three string to be exact. I have tried this simple test code in my main app class.
settings.setOnClickListener(new OnClickListener(){
@Override
public void onClick(View v) {
Intent intent = new Intent(v.getContext(), Settings.class);
startActivityForResult(intent, 0);}});
//Then a function
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent intent){
super.onActivityResult(requestCode, resultCode, intent);
Bundle extras = intent.getExtras();
String value = extras.getString("myKey");
if(value!=null){
Log.d("hmmm",value);}}}
In my settings.class I have the following
returnHome.setOnClickListener(new OnClickListener(){
@Override
public void onClick(View v) {
Intent intent = new Intent();
intent.putExtra("myKey", "YEAH");
setResult(RESULT_OK, intent);
finish();}});
Back in main app class it is not getting logged. Like I said I have three string in the main class that I want settings class to change and send back.
Android :: Passing Values From One Activity To Another
Feb 11, 2010I have an app which makes use of several layout-views. Every layout - view also got a class for it, which extend the Activity class. One class for example retrieves some database values whilst offering a search form to the user. Afterwards the user can select one of those values and he gets presented with another screen which gives similar options as the one selected. Anyways, I'd like for the first Activity to be able to send an array with data (Strings for example) to the second one. Right now I show an activity by using:
Intent i = new Intent(this, activitysName.class); startActivity(i);
I have no idea whilst using this construction how I can "initialize" the new object with the String array I want to pass to it. So how should this be achieved ? Should I be using something else instead of an Intent-Activity combination ?
Android :: Why Getting Same Values Of Different JSON Date?
Apr 16, 2010I 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);
} }
Android :: Updating TextView Values
Apr 9, 2009Hello everyone, and thanks in advance for the help. What I'm trying to do is a relatively simple task, but one that doesn't seem to be working. What I'm trying to do is display the Orientation X,Y,Z coordinates on the screen in basic TextView boxes. The sensors are constantly updating my Global.myOrientation float array, and then I'm running a Timed thread (I'm very new to threading, so forgive me if it's ugly, but it gets the job done almost). In this thread I just set the value of each TextView's text to the desired value. The problem is that it only seems to work the first time.
It correctly displays whatever my initial data is, but then subsequent runs of the thread do nothign to update the onscreen values when I change the orientation of the phone. LogCat output shows me that inside the run() method, the values of Global.getOrientationX,Y,Z are being updated correctly, and that the right data is being passed to TextView. How can I get around this limitation of TextView being initialized once and then immutable?
Any assistance in fixing this, or providing an alternate solution would be greatly appreciated. Code posted below:

Android :: Extending Themes - How To Put New Values?
May 8, 2010I have trouble (example<http://groups.google.com/group/android-developers/browse_thread/threa...>) wrapping my head around styles/themes. Can somebody help me or point me to actual documentation?
Let's say I have a drawable that I want to use as the background of a layout:
<shape xmlns:android="http://schemas.android.com/apk/res/android" android:shape="rectangle>
<gradient android:startColor="#9F9FA4" android:endColor="#66FFFFFF" android:angle="270" /> </shape>
Now I want to have a dark and a light theme. Depending on the chosen theme I want to have a different value for startColor and endColor. How do I do that? I am aware of extending themes, but what do I put into the items? How do I reference those new values then?

View 1 Replies View RelatedAndroid :: Multiple Alarms With Different Values Of ID
May 16, 2010I am setting multiple alarms like this, with different values of id. Multiple calls to AlarmManager.setRepeating deliver the same Intent/PendingIntent extra values, but I supplied different ones.
AlarmManager alarms = (AlarmManager)context.getSystemService(
Context.ALARM_SERVICE); Intent i = new Intent(MyReceiver.ACTION_ALARM);
// "com.example.ALARM" i.putExtra(MyReceiver.EXTRA_ID, id);
// "com.example.ID", 2 PendingIntent p = PendingIntent.getBroadcast(context, 0, i, 0);
alarms.setRepeating(AlarmManager.RTC_WAKEUP, nextMillis, 300000, p); // 5 mins
And receiving them like this:
public void onReceive(Context context, Intent intent) {
if (intent.getAction().equals(ACTION_ALARM)) {
// It's time to sound/show an alarm
final long id = intent.getLongExtra(EXTRA_ID, -1);
The alarm is delivered to my receiver at the right times, but often with EXTRA_ID set to the wrong value: it's a value that I have used at some point, just not the one that I wanted delivered at that particular time.
Android :: Getting Compass Values And Use It On Map Overlay
Sep 13, 2010I have a marker on the map using an Overlay. I also have access to the compass sensor which I'm able to show a textView with the orientation values (0 to 359). How can I apply this values to the marker? (which is a drawable). I already have a MAtrix created but when I insert the orientation value gives me an error, here it is:
GeoPoint geopoint = new GeoPoint((int) (newLocation.getLatitude() * 1E6),
(int) (newLocation.getLongitude() * 1E6)); Paint paint = new Paint();
Point pt = new Point(); mapView.getProjection().toPixels(geopoint, pt);
Bitmap bmp = BitmapFactory.decodeResource(getResources(),R.drawable.user2);
Matrix matrix = new Matrix(); matrix.postTranslate(-25, -25);
matrix.postRotate(direction); matrix.postTranslate(pt.x, pt.y);
paint.setAntiAlias(true); paint.setFilterBitmap(true);
int width = bmp.getWidth(); int height = bmp.getHeight();
Bitmap changedBitmap = Bitmap.createBitmap(bmp, 0, 0, width, height, matrix, true);
BitmapDrawable icon = new BitmapDrawable(changedBitmap);
icon.setBounds(0, 0, icon.getIntrinsicWidth(), icon.getIntrinsicHeight());
userOverlay useroverlay = new userOverlay(icon); useroverlay.addItem(item);
mapView.getOverlays().add(useroverlay);
I used the value retrieved from the sensor on "direction" but it doesn't work.

View 4 Replies View RelatedAndroid : Way To Get Realtime Gps Values While Not In A Mapview?
Jul 8, 2009I was wondering if it is possible to start the gps receiver on the phone if the current activity is not a mapactivity. I am displaying a listview and when I start the gps I get the last location found correctly, however the gps indicator never appears on top of the phone's display even if I wait or restart this activity. The location of the gps stays the some. The gps indicator appears on top only if I enter an activity where a mapview is displayed. If I wait in the map activity for a little while then If I go back to my other activity and request the location there, then the location is updated with the last value that it had before exiting the map view. It never gets updated If I move around after that, though..

View 3 Replies View RelatedAndroid : Way To Get Variable Values Back?
Feb 6, 2010I seriously need help with a quite strange problem. I created a client which communicates with a server. Therefore, I have three classes. An activity providing a nice dialog to configure some data, a background service which checks the connection status periodically and a server class which handles the socket connection. Originally, the background service owned a server connection object but because I could not manage to provide data from the activity to the service, I decided to create the server connection class as singleton. The user is now able to change data in the activity (IP, Port, Username, Password) which shall be transmitted to the server object, if the save button is pressed. The data is read correctly, the activity calls the setter of the server class and the logcat also says that this data is correctly applied to the variable that stores the data in the server class. However, if I try to start the socket connection still the old values are stored in my variables although they've been overwritten before. What I am doing wrong, or how can I fix this?
