I am trying to update a datetime column in an android sqlite db to use international date format (yyyy-mm-dd) instead of the current format (mm/dd/yyyy). I want to use the sqlite date() function to reformat the current value of the column. I thought it would be as simple as the following:
update tblename set thedate = date(thedate)
but the above does not work.
How would i write the sql statement to accomplish this?
thanks

I want to write an app that a parent can use to disable phone functionality to prevent their child from using it. One way the child could circumvent this is by uninstalling the app.
Is there a way to prevent application uninstall on the Android?
Hi,
Does anyone know of a way to obtain the phone service state (IN_SERVICE, OUT_OF_SERVICE, EMERGENCY_ONLY, POWER_OFF) in android.
I was hoping there would be a broadcastreciever to identify the changes, but I can't find anything. I know there's a listener but I'm not sure how I would use that from my app as it runs as a service using a WakefulIntentService (by thecommonsguy).
With something like battery level (ie BATTERY_LOW, BATTERY_OKAY) it's quite easy, but I just can't work out a similar things for phone service changes.

I am trying to create a Registration app with JSON to connect and post to MYSQL database. I created the following IF/ELSE statements to check for vacant input boxes, password match, and correct email characters before allowing it to be entered into the DATABASE. The code continues to execute the JSON posting even after the passwords don't match , invalid email characters are entered , and vacant text boxes are submitted. Why is it not returning and continuing to execute the JSON code?
try {
if (!inputEmail.getText().toString().matches("[a-zA-Z0-9._-]+@[a-z]+.[a-z]+") && email.length() > 0)
{
Toast.makeText(getApplicationContext(), "Enter Valid Email Address", Toast.LENGTH_LONG).show();
return;
}
else if(name.equals("") || email.equals("")|| password.equals("")||check.equals(""))
{
Toast.makeText(getApplicationContext(), "Field Vaccant", Toast.LENGTH_LONG).show();
return;
}
// check if both password matches
else if(!password.equals(checkpass))
{
Toast.makeText(getApplicationContext(), "Password does not match", Toast.LENGTH_LONG).show();
return;
}
if (json.getString(KEY_SUCCESS) != null) {
registerErrorMsg.setText("");
String res = json.getString(KEY_SUCCESS);
if(Integer.parseInt(res) == 1){
// user successfully registred
// Store user details in SQLite Database
DatabaseHandler db = new DatabaseHandler(getApplicationContext());
JSONObject json_user = json.getJSONObject("user");
// Clear all previous data in database
userFunction.logoutUser(getApplicationContext());
db.addUser(json_user.getString(KEY_NAME), json_user.getString(KEY_EMAIL), json.getString(KEY_UID), json_user.getString(KEY_CREATED_AT));
// Launch Dashboard Screen
Intent dashboard = new Intent(getApplicationContext(), DashboardActivity.class);
// Close all views before launching Dashboard
dashboard.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
startActivity(dashboard);
// Close Registration Screen
finish();
}else{
// Error in registration
registerErrorMsg.setText("User already Registered");
}
}
}
catch (JSONException e) {
}
}
});
I want to implement an android app which compares recorded audio files with our sound database and reports a similiarity metric. The app will work somehow like Shazam but is matched against our database audio files. Can anyone point me to an open source project which implements adequate algorithms to do the sound recogognition/comparision on our server ? Thanks
I'd like to put a couple images on a surfaceview. I understand that the screen sizes of android devices can vary, so I don't think I can just use an x y position or I might end up placing it off different screens. Say I want to put two boxes in the center of the screen, a blue one and a red one. The blue one is to the left of the red one. How can I accomplish that while accounting for different screen sizes?
I need as simple as possible solution for uploading files (eg. photos) to my website from mobile devices (iPhone, Android, BB, Nokia). Is it possible to do it in same way? Using Java or XHTML?
Hi,
I have a strange problem. To detect outgoing calls I have registered a broadcast receiver for android.intent.action.PHONE_STATE. When the state becomes OFFHOOK, then a conversation is started. It seems working on emulator: the debugger in fact reaches some code while it doesn't work on real device (Acer Liquid). Is it possible?
Which is a way to detect outgoing calls?
Thanks

I would like to know how I can display a HTML page in webview with references to relative/local images. The goal is to have the html page and all linked images contained in the android application package itself.
Where would I need to place the assets (assets directory?) and how do I reference these so they load into the webview?
Thanx!

Greets,
Made some app on android. I for the life of me can't get it to install on the phone as a stand alone application. It runs fine when I deploy from eclipse but never remains on the device. any idea whats happening?
I put the apk file on a web server, went to the address downloaded and installed but still it wasn't to be found.
I'm lost!
how can I use internal resource (e.g. R.drawable.myImage01) as an email attachment?
I tried the following code. It shows the file is attach but actually the email gets send without any attachment.
Context context = getApplicationContext();
String imagePath = context.getFilesDir() + "/" + "myImage01.png";
emailIntent.putExtra(android.content.Intent.EXTRA_STREAM, Uri.parse(imagePath));
Thanks

Hi all,
on Android, there's a Canvas class that represents a drawing surface. It has a clipping rect. Question - are the rect's right and bottom borders inclusive or exclusive? In other words - if the rect is (0, 0)-(10, 10), will the Canvas allow drawing in pixels at coordinates 10?
Hello,
I would like to know if there are some libraries/algorithms/techniques (python, if at all possible) that help to extract features from accelerometer data (extracted from and android phone, btw), like periodicity of movements, energy of acceleration and the like. Has anyone done this kind of task before?
Thank you very much in advance :)
