  • What's wrong with debugging in Eclipse on Android?

    - by Sebastian Dwornik
    I've obviously been spoiled by Visual Studio, because although I'm just learning Android and the Eclipse environment, debugging apps in Eclipse is becoming a serious detriment to further development. For example, Eclipse will compile this divide by zero just fine: public class Lesson2Main extends Activity { /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate (savedInstanceState); int i = 1 / 0; TextView tv = new TextView (this); tv.setText ("Hello, Android!"); setContentView (tv); } } And then, when it executes it under the debugger, I will get a full screen of useless debug info, non of which actually points me to the specific line containing the error. The stackTrace is null within the exception ('e') info tree, and it simply states a message stating 'ArithmeticException'. (that's nice, how about you point me in the direction of where you found it!?) I've looked all over the screen and am baffled that this IDE can't get this right. Does developing with Eclipse resort everyone back to 1991 with printf() like logging at every interval then to track down bugs? Seriously. Is there a configuration or plug-in that I'm missing to help with this? I haven't tested this case with XCode, but if the iPhone dev. IDE handles this more like Visual Studio, then no wonder the Android marketplace has so few apps. I'm excited about Android, but it seems that Eclipse is getting in the way.

  • iOS LocationManager is not updating location (Titanium Appcelerator module)

    - by vale4674
    I've made Appcelerator Titanium Module for fetching device's rotaion and location. Source can be found on GitHub. The problem is that it fetches only one cached location but device motion data is OK and it is refreshing. I don't use delegate, I pull that data in my Titanium Javascript Code. If I set "City Run" in Simulator - Debug - Location nothing happens. The same cached location is returning. Pulling of location is OK because I tried with native app wich does this: textView.text = [NSString stringWithFormat:@"%f %f\n%@", locationManager.location.coordinate.longitude, locationManager.location.coordinate.latitude, textView.text]; And it is working in simulator and on device. But the same code as you can see on GitHub is not working as Titanium module. Any ideas? EDIT: I am looking at GeolocationModule src and I see nothing special there. As I said, my code in my module has to work since it is working in native app. "Only" problem is that it is not updating location and it always returns me that cached location.

    Hello, new to Android. I get the following message in the debugger perspective: The source attachment does not contain the source for the file ListView.class You can change the source attachment by clicking the change attached Source Below Needless to say the app errors. I've tried to change the source attachment to the location path: C:/Program Files/Android/android-sdk-windows/platforms/android-8/android.jar However, this did not work.

  • View transform seems to be ignored when animating on iphone. Why?

    - by heymon
    I have views that can be rotated, scaled and moved around the screen. I want the view to resize and be orthogonal when the user double tap's the view to edit the textview within. The code is below. Somewhere the transform is getting reset. The NSLog statement below prints the identity transform, but a print of the transform when the animation is complete in transitionDidStop reveals that the transform is what it was before I thought I set it to identity. The view resizes, but it acts like the transform was never set to identity? Any ideas/pointers? originalBounds = self.bounds; originalCenter = self.center; originalTransform = self.transform; r = CGRectMake(0, 0, [UIScreen mainScreen].bounds.size.width - 70, 450); [UIView beginAnimations: nil context: NULL]; [UIView setAnimationDelegate: self]; [UIView setAnimationDidStopSelector: @selector(transitionDidStop:finished:context:)]; self.transform = CGAffineTransformIdentity; NSLog(@"%@ after set", NSStringFromCGAffineTransform([self transform])); [self setBounds: r]; [self setCenter: p]; [self setAlpha: 1.0]; [UIView commitAnimations]; [textView becomeFirstResponder];

  • RelativeLayout does not shrink in height

    - by rudas
    Hi, I cannot get my relative layuot view to shrink when using it in the follwing layout, used as a dialog. In below example the scrollview always expands to fill the entire dialog which looks very ugly if there is not much actual content. I have tried most combinations of fill_parent, wrap_content etc without success. The problem seems to be that setting the button to "align_bottom" will cause the dialog to fill its height. But if I change the order and have to button placed below the scrollview the button will not be visible if a lot of content is shown... Please help /Rudas <RelativeLayout android:id="@+id/RelativeLayout01" xmlns:android="http://schemas.android.com/apk/res/android" android:layout_height="wrap_content" android:layout_width="wrap_content"> <ScrollView android:id="@+id/ScrollView01" android:layout_above="@+id/dialogCloseButton" android:layout_alignParentTop="true" android:layout_width="wrap_content" android:layout_height="wrap_content"> <LinearLayout android:layout_width="wrap_content" android:layout_height="wrap_content" android:id="@+id/dialogContent" android:orientation="vertical" android:paddingBottom="10dp"> <TextView android:id="@+id/TextView01" android:layout_width="wrap_content" android:layout_height="wrap_content"> </TextView> </LinearLayout> </ScrollView> <Button android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="Close" android:id="@+id/dialogCloseButton" android:layout_alignParentBottom="true" android:layout_centerHorizontal="true"></Button> </RelativeLayout>

  • In a Tab Bar based app a controller release data of the other ! !

    - by Flodev03
    Hi all ! I've made a ViewBased app, in the app delegate i've set a UITabBarCotntroller, in the app i have different view Controller two of them displays text in a UITextView and labels, the other one is my "ShakeController" a UIViewController in which i've set a UIAcelerometerDelegate, in it i create a instance of UIAccelerometer, in the method which manages the shake everything works fine, in this controller i have also set a UIImageView to make a simple animation, in the view Did Load method i set my imageView.animation to an array of UIImage. My problem is : when the app is launched i use the ViewControllers and everything work fine, but when i tap the ShakeController item in the tab bar and then when i come back to the other controllers the label looks like : label and textView like : Lorem ipsum..... the text of UItextView in IB. I have noticed thaht if i comment the initialisation of my imageView to the array of image i can navigate the items (from a view controller to another) without the label change and stay what i want them to be. Notice that the two controllers are in a UINavigationController. (i use @proprety (nonnatomic, retain) then @synthesize ... then releqse in the dealloc for the labels textview and my uiimageView) Do not know what to do thanks to all

  • Dismiss a custom dialog?

    Hi, I'm trying to make a custom dialog to show a view in this dialog. This is the Builder code: //Getting the layout LayoutInflater inflater = (LayoutInflater) getSystemService(LAYOUT_INFLATER_SERVICE); View layout = inflater.inflate(R.layout.custom_dialog_simple, (ViewGroup) findViewById(R.id.rlDialogSimple)); //Change Text and on click TextView tvDialogSimple = (TextView) layout.findViewById(R.id.tvDialogSimple); tvDialogSimple.setText(R.string.avisoComprobar); Button btDialogSimple = (Button) layout.findViewById(R.id.btDialogSimple); btDialogSimple.setOnClickListener(new OnClickListener() { public void onClick(View v) { //Do some stuff //Here i want to close the dialog } }); AlertDialog.Builder builder = new AlertDialog.Builder(AcPanelEditor.this); builder.setView(layout); AlertDialog alert = builder.create(); alert.show(); So, i want to dismiss the dialog in the onClick of btDialogSimple. How i can do it? I don't know how to call the dismiss method from inside a onclicklistener. My buttons have a custom layout, so i don't want to make a builder.setPositiveButton. Any ideas?

  • Manually changing keyboard orientation for a view that's on top of a camera view

    - by XKR
    I'm basically trying to reproduce the core functionality of the "At Once" app. I have a camera view and another view with a text view on it. I add both views to the window. All is well so far. [window addSubview:imagePicker.view]; [window addSubview:textViewController.view]; I understand that the UIImagePickerController does not support autorotation, so I handle it manually by watching UIDeviceOrientationDidChangeNotifications and applying the necessary transforms to the textViewController.view. Now, the problem here is the keyboard. If I do nothing, it just stays in portrait mode. I can get it to rotate by adding the following code to the notification handler. [[UIApplication sharedApplication] setStatusBarOrientation:interfaceOrientation]; [textView resignFirstResponder]; [textView becomeFirstResponder]; However, the following simple test produces weird behavior. Start the app in portrait mode. Rotate the device 90 degrees clockwise. Rotate the device 90 degrees counterclockwise (back to the initial position). Rotate the device 90 degrees clockwise. After step 4, instead of the landscape-mode keyboard, the portrait-style keyboard is shown, skewed to fit in the landscape keyboard frame. Perhaps my approach is wrong from the start. I was wondering if anyone has been able to reliably make the keyboard change its orientation in response to setStatusBarOrientation.

  • Send Special Keys to Gtk.VteTerminal

    - by Ubersoldat
    Hi I have this OSS Project called Monocaffe connections manager which uses the Gtk.VteTerminal widget from PyGTK. A nice feature is that it allows the users to send commands to different servers' consoles (cluster mode) using a Gtk.TextView for the input. The way I send key strokes to each Gtk.VteTerminal is by using the feed_child method. For common keys there's no problem: I simply feed what the TextView receives to all the terminals, but when doing so with special keys I get into a little trouble. For "Return" I catch the event and feed the terminal a '\n'. For back-space is the same, catch the event and feed a '\b'. def cluster_backspace(self, widget): return self.cluster_send_key('\b') The problem comes with other keys like Tab, Arrows, Esc which I don't know how to feed as str to the terminal to recognize them. In the case of Esc is a real pain, because the users can edit the same file on different servers using vi, but cannot escape insert mode. Anyway, I'm not looking for a complete solution, just ideas since I've ran out of them. Thanks.

  • Custom Android control with children

    - by Gromix
    Hi, I'm trying to create a custom Android control that contains a LinearLayout. You can think of it as an extended LinearLayout with fancy borders, a background, an image on the left... I could do it all in XML (works great) but since I have dozens of occurences in my app it's getting hard to maintain. I thought it would be nicer to have something like this: /* Main.xml */ <MyFancyLayout> <TextView /> /* what goes inside my control's linear layout */ </MyfancyLayout> How would you approach this? I'd like to avoid re-writing the whole linear layout onMeasure / onLayout methods. This is what I have for the moment: /* MyFancyLayout.xml */ <TableLayout> <ImageView /> <LinearLayout id="container" /> /* where I want the real content to go */ </TableLayout> and /* MyFancyLayout.java */ public class MyFancyLayout extends LinearLayout { public MyFancyLayout(Context context) { super(context); View.inflate(context, R.layout.my_fancy_layout, this); } } How would you go about inserting the user-specified content (the TextView in main.xml) in the right place (id=container)? Cheers! Romain ----- edit ------- Still no luck on this, so I changed my design to use a simpler layout and decided to live with a bit of repeated XML. Still very interested in anyone knows how to do this though!

  • Getting an updated location in Android

    - by jul
    Hi, I'm using the code shown below to get an updated value for location every time a button is clicked. When my activity is resumed I get an update every second, so that when I call getLastKnownLocation I expect to have a location that have been updated in the last second. Is that the correct way to do that? I would expect the onLocationChanged event to be triggered every time I execute a 'geo fix' command (or max after 1s since I request update every 1s), but it's only triggered the first time. Why? Any help/suggestion welcome! Thanks package org.digitalfarm.atable; ... public class Atable extends Activity { private Button mSearchButton; private TextView mytext; private LocationManager locationManager; public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); mSearchButton = (Button)this.findViewById(R.id.button); mytext = (TextView) findViewById(R.id.dude); locationManager = (LocationManager)getSystemService(Context.LOCATION_SERVICE); final Criteria criteria = new Criteria(); criteria.setAccuracy(Criteria.ACCURACY_FINE); mSearchButton.setOnClickListener(new OnClickListener() { @Override public void onClick(View v) { String provider = locationManager.getBestProvider(criteria, true); Location location = locationManager.getLastKnownLocation(provider); } }); } //Start a location listener LocationListener onLocationChange=new LocationListener() { public void onLocationChanged(Location loc) { //sets and displays the lat/long when a location is provided String latlong = "Lat: " + loc.getLatitude() + " Long: " + loc.getLongitude(); mytext.setText(latlong); } public void onProviderDisabled(String provider) { // required for interface, not used } public void onProviderEnabled(String provider) { // required for interface, not used } public void onStatusChanged(String provider, int status, Bundle extras) { // required for interface, not used } }; //pauses listener while app is inactive @Override public void onPause() { super.onPause(); locationManager.removeUpdates(onLocationChange); } //reactivates listener when app is resumed @Override public void onResume() { super.onResume(); locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER,1000,100.0f,onLocationChange); } }

  • Calling web service from seems to hang

    - by anothershrubery
    I am trying to call an asmx web service from an Android app. Just literally started some Android development today. I've been following various solutions I have found on the net and on here and it seems it is more difficult than anticipated. I have tried various solutions and using KSoap2 seems to be the easiest way to implement this, well it would be if I could get it working. I have the following code which works up until a point: private class CallWebService extends AsyncTask<Void, Void, Void> { private static final String SOAP_ACTION = "http://tempuri.org/GetUser"; private static final String METHOD_NAME = "GetUser"; private static final String NAMESPACE = "http://tempuri.org/"; private static final String URL = "http://160.10.1.79:59315/Service1.asmx"; TextView tv; @Override protected Void doInBackground(Void... params) { tv=(TextView)findViewById(R.id.txtMessage); try { SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME); SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11); envelope.dotNet=true; envelope.setOutputSoapObject(request); HttpTransportSE androidHttpTransport = new HttpTransportSE(URL); androidHttpTransport.call(SOAP_ACTION, envelope); Object result = (Object)envelope.getResponse(); tv.setText(result.toString()); } catch (Exception e) { tv.setText(e.getMessage()); } return null; } } It seems to hang at the line androidHttpTransport.call(SOAP_ACTION, envelope); Any ideas why? Is this the correct approach? Should I be looking in another direction?

  • Save object in CoreData

  • TableLayout formatting loss after device rotation

    - by roundhill
    I'm seeing a strange issue with a TableLayout after the device is rotated from either orientation. If you load the view in either portrait or landscape mode, the table loads fine. But once you rotate the device, the columns collapse to just fit their width. I would expect that after rotation, the columns would still stretch to fit the width of the screen. Any ideas on what can be done to resolve this? Screenies and layout code below. Before Rotation: After Rotation: Table Layout: <TableLayout android:id="@+id/dataTable" android:layout_width="fill_parent" android:layout_height="fill_parent" android:layout_weight="1" android:layout_below="@id/chart" android:stretchColumns="*" android:shrinkColumns="*" android:padding="6dip" > </TableLayout> Table Row: <TableRow xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="fill_parent"> <TextView android:id="@+id/col1" android:layout_marginRight="2dip" android:textColorLink="#FF21759b" android:text="Column 1" android:padding="4dip" android:textColor="#FF464646"/> <TextView android:id="@+id/col2" android:text="Column 2" android:textColor="#FF464646" android:padding="4dip"/> </TableRow> Thanks!

  • What could possibly be causing this NPE in onCreate?

    - by Adam Johns
    I am getting an NPE in onCreate of the following file (MySubActivity): public class MySubActivity extends MySuperActivity { @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); myTextView.setText(getResources().getString(R.string.myString)); } } MySuperActivity: public class MySuperActivity extends Activity { protected TextView myTextView; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.my_layout); myTextView = (TextView)findViewById(R.id.myTextViewid); } } The strange thing is that I have never seen this crash while testing the app. The page works fine when I test it. However I got a crash report from Google notifying me of the crash. I cannot reproduce it, and I have no idea under what scenario this crash could happen. Seeing as how it works for me, the resource ids and string names etc. must be correct. The only thing that came across my mind was that maybe the user had their phone set to a different language, so it couldn't properly pull the resources. However, there are default resources for all of them, and I tested changing the language of my emulator and it didn't crash. Any ideas?

Unfortunately the list covers(i.e. above on the z axis) the header so the header text is not visible instead of being underneath (on the y axis) <?xml version="1.0" encoding="utf-8"?> <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="wrap_content" android:layout_height="wrap_content"> <TextView android:id="@+id/footer" android:text="footer" android:layout_height="wrap_content" android:layout_width="fill_parent" android:layout_alignParentBottom="true" /> <ListView android:id="@+id/list_view" android:layout_height="fill_parent" android:layout_width="fill_parent" android:layout_above="@id/footer" android:background="#ff9999ff"/> <TextView android:id="@+id/header" android:text="header" android:layout_height="wrap_content" android:layout_width="fill_parent" android:layout_alignParentTop="true" android:layout_above="@id/list_view" android:baselineAlignBottom="false" /> </RelativeLayout> Here is the corresponding Activity class: public class SampleListActivity extends Activity { @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.list_activity); } }

  • search a listview in Persian

    - by user3641353
    I have listview with textview which I use textview for search items in listview. It works true but just in English. I can not change the keyboard to Persian. Do you have any solution? this is my code: ArrayAdapter<String> adapter; String[] allMovesStr = {"??? ???? ????","?? ???? ????","?? ???? ????? ???????"}; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.all_moves); adapter = new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, allMovesStr); setListAdapter(adapter); EditText ed = (EditText) findViewById(R.id.inputSearch); ListView lv = (ListView) findViewById(android.R.id.list); lv.setTextFilterEnabled(true); ed.addTextChangedListener(new TextWatcher() { public void onTextChanged(CharSequence arg0, int arg1, int arg2, int arg3) { // TODO Auto-generated method stub } public void beforeTextChanged(CharSequence arg0, int arg1, int arg2, int arg3) { // TODO Auto-generated method stub } public void afterTextChanged(Editable arg0) { // vaghti kar bar harfi vared kard josteju mikone : AllMoves.this.adapter.getFilter().filter(arg0); } }); }

  • How to run an async task afor every x mins in android?

    - by Shan
    how to run the async task at specific time? (I want to run it every 2 mins) I tried using post delayed but it's not working? tvData.postDelayed(new Runnable(){ @Override public void run() { readWebpage(); }}, 100); In the above code readwebpage is function which calls the async task for me.. Right now below is the method which I am using public void onCreate(Bundle savedInstanceState) { readwebapage(); } public void readWebpage() { DownloadWebPageTask task = new DownloadWebPageTask(); task.execute("http://www.google.com"); } private class DownloadWebPageTask extends AsyncTask<String, Void, String> { @Override protected String doInBackground(String... urls) { String response1 = ""; response1=read(); //read is my another function which does the real work response1=read(); super.onPostExecute(response1); return response1; } protected void onPostExecute(String result) { try { Thread.sleep(100); } catch (InterruptedException e) { // TODO Auto-generated catch block e.printStackTrace(); } TextView tvData = (TextView) findViewById(R.id.TextView01); tvData.setText(result); DownloadWebPageTask task = new DownloadWebPageTask(); task.execute(new String[] { "http://www.google.com" }); } } This is what I my code is and it works perfectly fine but the big problem I drains my battery?
