  • What is wrong with this layout? Android

    - by kellogs
    Hi, I am trying to accomplish a view like this: left side = live camera preview, right side = a column of 4 images. But all that I managed with the following xml was a fullscreen live camera preview. Android 1.5 emulator. Thanks <?xml version="1.0" encoding="utf-8"?> <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="fill_parent"> <proto.wiinkme.SurfaceViewEx android:id="@+id/preview" android:layout_height="fill_parent" android:layout_width="wrap_content" android:layout_alignParentLeft="true" android:layout_weight="3"/> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="vertical" android:layout_width="wrap_content" android:layout_height="fill_parent" android:layout_toRightOf="@+id/preview" android:layout_alignParentRight="true" android:layout_weight="1"> <ImageView android:layout_width="fill_parent" android:layout_height="fill_parent" android:id="@+id/mother_earth" android:src="@drawable/mother_earth_show" /> <ImageView android:layout_width="fill_parent" android:layout_height="fill_parent" android:id="@+id/meadow" android:src="@drawable/meadow_show" /> <ImageView android:layout_width="fill_parent" android:layout_height="fill_parent" android:id="@+id/trap" android:src="@drawable/trap_show" /> <ImageView android:layout_width="fill_parent" android:layout_height="fill_parent" android:id="@+id/whistle" android:src="@drawable/whistle_show" /> </LinearLayout> </RelativeLayout>

  • Bouncycastle encryption algorithms not provided

    - by David Read
    I'm trying to use BouncyCastle with android to implement ECDH and EL Gamal. I've added the bouncycastle jar file (bcprov-jdk16-144.jar) and written some code that works with my computers jvm however when I try and port it to my android application it throws: java.security.NoSuchAlgorithmException: KeyPairGenerator ECDH implementation not found A sample of the code is: Security.addProvider(new org.bouncycastle.jce.provider.BouncyCastleProvider()); java.security.KeyPairGenerator keyGen = org.bouncycastle.jce.provider.asymmetric.ec.KeyPairGenerator.getInstance("ECDH", "BC"); ECGenParameterSpec ecSpec = new ECGenParameterSpec("prime192v1"); keyGen.initialize(ecSpec, SecureRandom.getInstance("SHA1PRNG")); KeyPair pair = keyGen.generateKeyPair(); PublicKey pubk = pair.getPublic(); PrivateKey prik = pair.getPrivate(); I then wrote a simple program to see what encryption algorithms are available and ran it on my android emulator and on my computers jvm the code was: Set<Provider.Service> rar = new org.bouncycastle.jce.provider.BouncyCastleProvider().getServices(); Iterator<Provider.Service> ir = rar.iterator(); while(ir.hasNext()) System.out.println(ir.next().getAlgorithm()); On android I do not get any of the EC algorithms while ran normally on my computer it's fine. I'm also getting the following two errors when compiling for a lot of the bouncy castle classes: 01-07 17:17:42.548: INFO/dalvikvm(1054): DexOpt: not resolving ambiguous class 'Lorg/bouncycastle/asn1/ASN1Encodable;' 01-07 17:17:42.548: DEBUG/dalvikvm(1054): DexOpt: not verifying 'Lorg/bouncycastle/asn1/ess/OtherSigningCertificate;': multiple definitions What am I doing wrong?

  • How to get the stacktrace in a mobile device?

    - by Daniel Moura
    I'm getting a NullPointerException in a Nokia S40. I want to know what is causing this exception. The device shows: NullPointerException java/lang/NullPointerException This error only occurs in the device, running in the emulator the application works fine. I use microlog to debug my application. But the application works fine if the log is enabled. Is there a way to get the stack trace when I get this NullPointerException? I don't need all details like the line number just which method cause this exception. UPDATE: I installed the same application in another Nokia S40 and the same error didn't occur. Nokia 2660 - error Nokia 6131 - no error UPDATE 2: Somehow I find what was causing the NullPointerException. import javax.microedition.lcdui.Canvas; import javax.microedition.lcdui.Graphics; public class OuterClass extends Canvas { private Config config; public OuterClass() { this.config = new Config(); } public void paint(Graphics graphics) { HelperClass helper = new HelperClass(this.config); helper.doStuff(); } public void dispose() { this.config = null; } public class Config implements IConfig { public int getSomething() { // ... } } } public class HelperClass { private IConfig config; public HelperClass(IConfig) { this.config = config; } public doStuff() { config.getSomething(); // Here is thrown NullPointerException } } In some situations a thread is started and call the OuterClass.dispose() before the helper.doStuff() causing the NPE. I think when I enabled the log it made the thread slower and helper.doStuff() was called when I expected it to be called.

  • Can you add a UITableViewController's TableView to another View?

    - by Dan Harrelson
    I've inserted a UITableViewController and it's corresponding UITableView into a simple IB document. The goal is to include the UITableView inside of a parent UIWindow (or UIView) with other "stuff" (anything really) adorning the table. Here's what that might look like in Interface Builder. http://danharrelson.com/images/skitch/iphone-tableview-3-20090701-205535.png I've tried this numerous times and always get to the same place. Build a working subclass of UITableViewController filled with data Customize the UTableView and it's cells including tap targets Add the newly created UITableViewController into an IB document Drag the UITableView out of the UITableViewController and into the main UIView Wire up the UITableViewController to the UITableView Note: adding the UITableViewController in code results in the same problem When running the app in the iPhone emulator or on a device the table displays correctly, but crashes the first time you try and interact with it. A scroll, a tap, anything crashes the app. This seems to be a delegate problem, like the UITableView doesn't know how to communicate back to the UITableViewController, but I have no idea how to correct the problem. So far I have been able to get by by customizing the tableHeaderView to get layouts that suffice, but I'd really prefer to have the other technique work.

  • How to know when StatusBar size changed (iPhone)

    - by JOM
    I have UITabBarController with 2 tabs. One resizes just fine, when StatusBar size changes (emulator "Toggle In-Call Status Bar" menu item). The other one doesn't. The problematic tab item contains a static view, which dynamically loads one or another view depending on certain things. While getting this setup working I discovered that main tab view did NOT automagically send e.g. viewWillAppear and viewWillDisappear messages to my dynamic subviews. Apple docs explained this was because dynamically added views were not recognized by the system. @interface MyTabViewController : UIViewController { UIView *mainView; FirstViewController *aController; SecondViewController *bController; } ... if (index == 0) { self.aController = [[FirstViewController alloc] initWithNibName:@"FirstViewController" bundle:nil]; [self.mainView addSubview:aController.view]; [self.aController viewWillAppear:YES]; } How can I get StatusBar size changed event into my dynamic subviews? The "didChangeStatusBarFrame" doesn't work, as documented elsewhere.

  • How can I get the correct DisplayMetrics from an AppWidget in Android?

    - by Gary
    I need to determine the screen density at runtime in an Android AppWidget. I've set up an HDPI emulator device (avd). If set up a regular executable project, and insert this code into the onCreate method: DisplayMetrics dm = getResources().getDisplayMetrics(); Log.d("MyTag", "screen density " + dm.densityDpi); This outputs "screen density 240" as expected. However, if I set up an AppWidget project, and insert this code into the onUpdate method: DisplayMetrics dm = context.getResources().getDisplayMetrics(); Log.d("MyTag", "screen density " + dm.densityDpi); This outputs "screen density 160". I noticed, hooking up the debugger, that the mDefaultDisplay member of the Resources object here is null in the AppWidget case. Similarly, if I get a resource at runtime using the Resources object obtained from context.getResources() in the AppWidget, it returns the wrong resource based on screen density. For instance, I have a 60x60px drawable for mdpi, and an 80x80 drawable for hdpi. If I get this Drawable object using context.getResources().getDrawable(...), it returns the 60x60 version. Is there any way to correctly deal with resources at runtime from the context of an AppWidget? Thanks!

  • Exception in setDrawingCache in Android 1.5?

    - by sunil
    Hi, I am developing an application where I am using setDrawingCache and then once I get the Bitmap I destroy the cache by using destroyDrawingCache(). The application has been developed with Android SDK 1.6. When testing the application in emulator with Android 1.5 the application throws NullPointerException when try to manipulate the Bitmap returned by getDrawingCache(). It probably gives error since getDrawingCache returns null. The interesting thing in this is that the NullPointerException comes only after I run the application twice or thrice. It means I am able to get the Bitmap for two times and then it throws this exception. The error that I am getting is as below java.lang.NullPointerException E/AndroidRuntime( 1036): at com.babbleville.HomeScreenActivity.resizeBitmap(HomeScreenActivity.java: 394) E/AndroidRuntime( 1036): at com.babbleville.HomeScreenActivity.access $0(HomeScreenActivity.java:392) E/AndroidRuntime( 1036): at com.babbleville.HomeScreenActivity $1.handleMessage(HomeScreenActivity.java:327) E/AndroidRuntime( 1036): at android.os.Handler.dispatchMessage(Handler.java:99) E/AndroidRuntime( 1036): at android.os.Looper.loop(Looper.java:123) E/AndroidRuntime( 1036): at android.app.ActivityThread.main(ActivityThread.java:3948) E/AndroidRuntime( 1036): at java.lang.reflect.Method.invokeNative(Native Method) E/AndroidRuntime( 1036): at java.lang.reflect.Method.invoke(Method.java:521) E/AndroidRuntime( 1036): at com.android.internal.os.ZygoteInit $MethodAndArgsCaller.run(ZygoteInit.java:782) E/AndroidRuntime( 1036): at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:540) E/AndroidRuntime( 1036): at dalvik.system.NativeStart.main(Native Method) Can someone please let me know the problem?

  • Unable to download .apk via webbrowser from drupal site

    - by ggrell
    I have a drupal-based website where people can log in and see private discussion forums. This is where I want to have my beta testers for my Android application download the beta .apk files. I tested this thoroughly on my Android 1.6 based myTouch 3G, and was able to log in, and download files attached to forum posts without problems. Now comes the interesting part: my testers on Droids and Nexus Ones (Android 2.0.1 and 2.1) were complaining that their downloads are failing. Since I don't have an 2.0 phone, I tried it out in a 2.0 emulator, and lo-and-behold, it didn't work. The download shows the indeterminate progress for a second or two, then shows "Download unsuccessful". Based on what I see in the logs, it is apparent that the server is returning a 404 for the download request from 2.0 browsers. I can download to my desktop and 1.6 phone no problem. The only reason I can think of that the server would return a 404 for a request is that for some reason the credentials or cookies aren't being passed by the download process. Logcat shows: http error 404 for download x Some background: I added the mime type to my .htaccess like this: AddType application/vnd.android.package-archive apk I checked the server logs and see the following for failed downloads: xx.xx.xx.224 - - [28/Jan/2010:20:39:00 -0500] "GET /system/files/grandmajong-beta090.apk HTTP/1.1" 404 - "http://trickybits.com/forums/beta-testing/grandma-jong/latest-version-090-b1" "Mozilla/5.0 (Linux; U; Android 1.6; en-us; sdk Build/Donut) AppleWebKit/528.5+ (KHTML, like Gecko) Version/3.1.2 Mobile Safari/525.20.1"

  • Android: Can not send http post

    - by jpartogi
    Hi all, I've been banging my head trying to figure out how to send a post method in Android. This is how my code look like: public class HomeActivity extends Activity implements OnClickListener { private TextView textView; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); textView = (TextView) findViewById(R.id.text); Button button = (Button)findViewById(R.id.button); button.setOnClickListener(this); } @Override public void onClick(View view) { HttpPost httpMethod = new HttpPost("http://www.example.com/"); httpMethod.addHeader("Accept", "text/html"); httpMethod.addHeader("Content-Type", "application/xml"); AndroidHttpClient client = AndroidHttpClient.newInstance("Android"); String result = null; try { HttpResponse response = client.execute(httpMethod); textView.setText(response.toString()); HttpEntity entity = response.getEntity(); Log.i(HomeActivity.class.toString(), result); textView.setText("Invoked webservice"); } catch (IOException e) { e.printStackTrace(); Log.e(HomeActivity.class.toString(), e.getMessage()); textView.setText("Something wrong:" + e.getMessage()); } } } What am I doing wrong here? Is there anything that I may need to configure from the Android emulator to get this working? Thank you for your help.

  • MissingMethodException thrown when calling new form in Compact Framework

    - by Boerema
    I'm updating an old mobile device application for better flexibility. I had basically added the ability to configure the address of our SQL server in the case that we want to use our test server as opposed to our production server. I don't think this is causing the problem, but I wanted to state it. I also upgraded the project from a VS 2000 project to a VS 2005 project. The issue I am having is that when I try to run the program in the VS emulator for Pocket PC, I get an error. It occurs after our "main menu" form loads and the user selects the next form to load. The form is initialized without issue, but when we try to run the .ShowDialog() method, it throws a System.MissingMethodException. I don't have a lot of experience with the Compact Framework and really have no idea where to start looking for problems. I stepped the debugger through the entire initializing process for the new form and it ran without issue. But, again, when we come to the ShowDialog call, it throws the error. Any ideas in where to start looking or known issues would be greatly appreciated.

  • How do I get my ActivityUnitTestCases to sync with the MessageQueue thread and call my Handler?

    - by Ricardo Gladwell
    I'm writing unit tests for a ListActivity in Android that uses a handler to update a ListAdapter. While my activity works in the Android emulator, running the same code in a unit test doesn't update my adapter: calls to sendEmptyMessage do not call handleMessage in my activity's Handler. How do I get my ActivityUnitTestCase to sync with the MessageQueue thread and call my Handler? The code for the Activity is somewhat like this: public class SampleActivity extends ListActivity implements SampleListener { List samples = new ArrayList(); public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.sample_list); listView.setEmptyView(findViewById(R.id.empty)); } private final Handler handler = new Handler() { @Override public void handleMessage(Message msg) { // unit test never reaches here sharesAdapter = new SampleAdapter(SampleActivity.this, samples); setListAdapter(sharesAdapter); } }; public void handleSampleUpdate(SampleEvent event) { samples.add(event.getSample()); handler.sendEmptyMessage(0); } } The code for my unit test is somewhat like this: public class SampleActivityTest extends ActivityUnitTestCase<SampleActivity> { public SampleActivityTest() { super(SampleActivity.class); } @MediumTest public void test() throws Exception { final SampleActivity activity = startActivity(new Intent(Intent.ACTION_MAIN), null, null); final ListView listView = (ListView) activity.findViewById(android.R.id.list); activity.handleSampleUpdate(new SampleEvent(this)); // unit test assert fails on this line: assertTrue(listView.getCount() == 1); } }

  • qt on Win CE 5.0 crash

    - by Michael
    Good day all, It's the first time I am using Qt on Windows CE and I ran into an issue. Maybe someone can help me with it. I will describe my set up. I am using XP with Visual Studio 2005 an Qt Add-in version 1.1.2. I downloaded Qt source for Windows CE and followed the instructions on these (http://doc.trolltech.com/4.4/install-wince.html) instructions to build the library for CE. I then used the Visual Studio to create a minimal Qt Windows CE Application. The program runs fine in the CE emulator, but once I try to deploy it on the device it crashes with the following message: Load module: qt_ce_3.exe Load module: QtGui4.dll Load module: msvcr80.dll Load module: QtCore4.dll Load module: CEShell.DLL Load module: OLEAUT32.dll Load module: commctrl.dll.0409.MUI Load module: commctrl.dll Load module: aygshell.dll Load module: WS2.dll Load module: WINSOCK.dll Load module: coredll.dll.0409.MUI Load module: ossvcs.dll Load module: ole32.dll Load module: coredll.dll Load module: MMTimer.dll Data Abort: Thread=8fb09a40 Proc=8c4ecea0 'qt_ce_3.exe' AKY=00040001 PC=012a80b0(qtcore4.dll+0x000680b0) RA=012a8168(qtcore4.dll+0x00068168) BVA=676e4574 FSR=000000f5 Unhandled exception at 0x012a80b0 in qt_ce_3.exe: 0xC0000005: Access violation reading location 0x676e4574. I tried it on two devices from different manufacturers, and the result is the same. Debug version worked on one of them, ran out of memory on the other. Does anyone have any idea what this could be?

  • Newbie question: How do you layout an icon, 2 text lines and a button?

    - by Keith Barrows
    I am trying to extend a sample I found at http://developer.android.com/resources/articles/layout-tricks-efficiency.html. I am a brand new MonoDroid developer, just installed it yesterday, and trying to jump right into UI design and so far it is not clicking for me completely. I have this main.xml: <?xml version="1.0" encoding="utf-8"?> <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="?android:attr/listPreferredItemHeight" android:padding="6dip"> <ImageView android:id="@+id/icon" android:layout_width="wrap_content" android:layout_height="fill_parent" android:layout_alignParentTop="true" android:layout_alignParentBottom="true" android:layout_marginRight="6dip" android:src="@drawable/icon" /> <TextView android:id="@+id/secondLine" android:layout_width="200dip" android:layout_height="26dip" android:layout_toRightOf="@id/icon" android:layout_alignParentBottom="true" android:layout_alignParentRight="true" android:singleLine="true" android:ellipsize="marquee" android:text="Second line which is a long line of text and needs to scroll" /> <TextView android:id="@+id/firstLine" android:layout_width="200dip" android:layout_height="wrap_content" android:layout_toRightOf="@id/icon" android:layout_alignParentRight="true" android:layout_alignParentTop="true" android:layout_above="@id/secondLine" android:layout_alignWithParentIfMissing="true" android:singleLine="true" android:ellipsize="marquee" android:gravity="center_vertical" android:text="First line" /> <Button android:id="@+id/logonButton" android:layout_width="50dip" android:layout_height="wrap_content" android:layout_toRightOf="@id/secondLine" android:layout_alignParentRight="true" android:layout_alignParentTop="true" android:gravity="center_vertical" android:text="Login" /> /> </RelativeLayout> What I am trying to do is have an icon on the left, 2 lines of text stacked in the middle and a button on the right. When I run this in my emulator I am seeing: The second line is not scrolling. The button does not show up. Is there by any chance a simple WYSIWYG editor for layout? Or is there an app to give me a quick view of my layout XML? Something like FireBug in FireFox would be fine. Barring the slim chance there are UI helpers for Droid, what am I doing wrong? :)

  • Android App Build system differences between Eclipse and Ant?

    - by Amy Winarske
    The Eclipse build for my 1.6 application project is succeeding and the Ant build is failing. I'm looking for help on why they aren't behaving the same way. We are developing on Mac OSX 10.5.8 with Eclipse 3.5 against SDK 1.6 + Google APIs. There are no setting changes in Eclipse, either at workspace or project level. Similarly, our ant is also a vanilla- flavored unmodified installation of 1.7.1. JDK is 1.5.0_22. The CLASSPATH environment variable is not set. JAVA_HOME is /Library/Java/ Home The application was initially created by a team member using the Eclipse plugins. The application references two jar files, one of which has a dependency on javax.xml.bind.annotation.XmlSeeAlso, which is not defined anywhere in our code or in android.jar. The other jar file has an explicit dependency on android.jar. I generated the Ant build file using android update. The Eclipse project builds an apk and runs the application in the emulator. I think this is incorrect behavior. The Android ant project fails to build. I think this is correct behavior. MyClass.java:98: cannot access javax.xml.bind.annotation.XmlSeeAlso [javac] file javax/xml/bind/annotation/XmlSeeAlso.class not found Any ideas as to why the two build methods are behaving differently? I would expect them both to fail. Thanks! -Amy

    - by svebee
    Inside public class IAmHere extends Activity implements LocationListener { i have @Override public void onLocationChanged(Location location) { // TODO Auto-generated method stub } @Override public void onProviderDisabled(String provider) { // TODO Auto-generated method stub } @Override public void onProviderEnabled(String provider) { // TODO Auto-generated method stub } @Override public void onStatusChanged(String provider, int status, Bundle extras) { // TODO Auto-generated method stub } and inside public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.iamhere); i have LocationManager lm = (LocationManager) getSystemService(Context.LOCATION_SERVICE); List<String> providers = lm.getProviders(true); /* Loop over the array backwards, and if you get an accurate location, then break out the loop*/ Location l = null; for (int i=providers.size()-1; i>=0; i--) { l = lm.getLastKnownLocation(providers.get(i)); if (l != null) break; } double[] gps = new double[2]; if (l != null) { gps[0] = l.getLatitude(); gps[1] = l.getLongitude(); } gpsString = (TextView)findViewById(R.id.gpsString); String Data = ""; String koordinata1 = Double.toString(gps[0]); String koordinata2 = Double.toString(gps[1]); Data = Data + koordinata1 + " | " + koordinata2 + "\n"; gpsString.setText(String.valueOf(Data)); but seems it's not working? Why? I mean even emulator doesn't want to send GPS data - When I click "send" via UI or console, nothing happens...? Thank you.

  • Overlay only draws between first 2 points in Android

    - by LordSnoutimus
    Hi, I am experiencing an unusual error using ItemizedOverlay in Android. I am creating a GPS tracking device that plots a route between waypoints stored in a database. When I provide the first two sets of longitude and latitude points through the emulator in Eclipse, it draws a red line just how I want it, but if I send another GPS point, it animates to the point, but does not draw a line from the last point. public class MyOverlay extends ItemizedOverlay { // private Projection projection; private Paint linePaint; private Vector points; public MyOverlay(Drawable defaultMarker) { super(defaultMarker); points = new Vector<GeoPoint>(); //set colour, stroke width etc. linePaint = new Paint(); linePaint.setARGB(255, 255, 0, 0); linePaint.setStrokeWidth(3); linePaint.setDither(true); linePaint.setStyle(Style.FILL); linePaint.setAntiAlias(true); linePaint.setStrokeJoin(Paint.Join.ROUND); linePaint.setStrokeCap(Paint.Cap.ROUND); } public void addPoint(GeoPoint point) { points.addElement(point); } public void draw(Canvas canvas, MapView view, boolean shadow) { int size = points.size(); Point lastPoint = new Point(); if(size == 0) return; view.getProjection().toPixels(points.get(0), lastPoint); Point point = new Point(); for(int i = 1; i<size; i++){ view.getProjection().toPixels(points.get(i), point); canvas.drawLine(lastPoint.x, lastPoint.y, point.x, point.y, linePaint); lastPoint = point; } } @Override protected OverlayItem createItem(int arg0) { // TODO Auto-generated method stub return null; } @Override public int size() { // TODO Auto-generated method stub return 0; } }

  • Problem inserting android.text.format.Time.toMillis value into SQLite DB on droid

    - by schusselig
    I'm writing an app for Android OS, and I need to store some time values in the SQLite DB. I have been using android.text.format.Time to store the time values in the app, and then inserting the values as millis into the DB as REAL values. On the SDK emulator, everything works perfectly. On the sole phone I've had the opportunity to test my app (so far), my duration code doesn't work as expected. Some relevant code: private static final String DATABASE_CREATE = "create table " + DATABASE_TABLE + " (" + KEY_ROWID + " integer primary key autoincrement, " + KEY_START + " REAL, " + KEY_STOP + " REAL, " + KEY_DUR + " REAL );"; ... private SQLiteDatabase mDb; ContentValues timerValues = new ContentValues(); ... timerValues.put(KEY_START, stime.toMillis(false)); timerValues.put(KEY_STOP, etime.toMillis(false)); timerValues.put(KEY_DURATION, stime.toMillis(false)-etime.toMillis(false)); int result = mDb.insert(DATABASE_TABLE, null, timerValues); I pull this data from two separate functions with slightly different bits of code, both using Time.set(long millis), both giving incorrect results: The start and stop values come back correct, but the duration comes out 17 hours too large. Am I missing something about calculating durations or does this just seem like there's something "special" about this particular droid? I'll have another droid to test on Monday, but any ideas are appreciated.

  • Permission denied (maybe missing INTERNET permission) when calling web service

    - by Maxim
    I'm trying to use .net SOAP web service with ksoap2 lib. Example from http://www.vimeo.com/9633556 shows how to do it correct. Below the code from that example. everything shoud work ok, but when I try to do a call inself (httpTransport.call) I get "Permission denied (maybe missing INTERNET permission)" exception. Moreover, I don't see in the Application info window among permissions the internet permission alert. Tried this on emulator and Google phone. Will be very appreciated if somebody could help with it. Thanks. public void CelsiusToFahrenheit() { String SOAP_ACTION = "http://tempuri.org/CelsiusToFahrenheit"; String METHOD_NAME = "CelsiusToFahrenheit"; String NAMESPACE = "http://tempuri.org/"; String URL = "http://www.w3schools.com/webservices/tempconvert.asmx"; SoapObject Request = new SoapObject(NAMESPACE, METHOD_NAME); Request.addProperty("Celsius", "32"); SoapSerializationEnvelope soapEnvelope = new SoapSerializationEnvelope(SoapEnvelope.VER11); soapEnvelope.dotNet = true; soapEnvelope.setOutputSoapObject(Request); AndroidHttpTransport httpTransport = new AndroidHttpTransport(URL); try { httpTransport.call(SOAP_ACTION, soapEnvelope); SoapPrimitive resultString = (SoapPrimitive)soapEnvelope.getResponse(); res = resultString.toString(); } catch (Exception e) { e.printStackTrace(); } } AndroidManifest.xml <?xml version="1.0" encoding="utf-8"?> <manifest> <application> <intent-filter> <action android:name="android.intent.action.MAIN" /> <category android:name="android.intent.category.LAUNCHER" /> </intent-filter> </activity> </application> <user-permission android:name="android.permission.INTERNET"></user-permission> <uses-sdk android:minSdkVersion="4" />

  • Pressing back button in ActivityGroup causes it to pause, and then continue shutting down the next t

    - by synic
    Pressing the back button causes onPause to be called, and the app stays paused until it is re-launched by clicking on the icon, at which point, onDestroy gets called, and the main activity continues to shut down. Simple class to demonstrate. Note, as far as I can tell, this only happens on the Nexus One. I can't reproduce it in the emulator or on my Droid. package com.vimtips.testshutdown; import android.app.ActivityGroup; import android.os.Bundle; import android.util.Log; import android.view.KeyEvent; public class MainActivity extends ActivityGroup { private static final String TAG = "MainActivity"; private int counter = 3; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); } public boolean onKeyDown(int keyCode, KeyEvent event) { if(keyCode == KeyEvent.KEYCODE_BACK) { if(counter-- > 0) return true; } return super.onKeyDown(keyCode, event); } @Override public void onPause() { super.onPause(); Log.d(TAG, "onPause called"); } @Override public void onDestroy() { super.onDestroy(); if(isFinishing()) { Log.d(TAG, "Shutting down"); } } } And here's the log: I/ActivityManager( 132): Starting activity: Intent { act=android.intent.action.MAIN cat=[android.intent.category.LAUNCHER] flg=0x10100000 cmp=com.vimtips.testshutdown/.MainActivity } I/ActivityManager( 132): Displayed activity com.vimtips.testshutdown/.MainActivity: 305 ms (total 305 ms) D/MainActivity( 1393): onPause called I/ActivityManager( 132): Displayed activity com.vimtips.testshutdown/.MainActivity: 302 ms (total 302 ms) D/MainActivity( 1393): Shutting down This doesn't appear to happen on a normal Activity, just an Activity group, though looking at Android's sourcecode, I can't figure out why. It's causing some serious problems with my app. Anyone know why this would happen?

  • RelativeLayout differences between 1.5 and 2.1

    - by Kilnr
    I've got a ListView with items composed of RelativeLayouts. This is the relevant XML from the list items: <?xml version="1.0" encoding="utf-8"?> <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="wrap_content"> <TextView android:id="@+id/xx" android:gravity="center_vertical" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_gravity="center_vertical" android:layout_centerInParent="true" android:layout_alignParentLeft="true"/> <TextView android:id="@+id/title" android:layout_width="fill_parent" android:layout_height="wrap_content" android:layout_toRightOf="@id/xx" /> <TextView android:id="@+id/tag" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_toRightOf="@id/xx" android:layout_below="@id/title" /> <TextView android:id="@+id/subtitle" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_toRightOf="@id/tag" android:layout_below="@id/title" /> </RelativeLayout> On Android 2.1 (tested on a Nexus One), this shows the desired behavior: On Android 1.5 however (tested on a HTC Hero), it shows up like this: [edit] On 1.6 (emulator), it works as expected as well. The small grey line on the top left is what shows up in the first pic as "xx", so that should be vertically centered. As far as I can see, the XML dictates this, but for some reason, 1.5 ignores it. Why is this? I can't find anything about this difference, and I've been brute forcing any combination of layout_center, center, alignParent*, but to no avail... Can anyone shed some light on this? Thanks!

  • Display an Android Sensors List

    - by Skatephone
    I'm trying to display a list of available sensors but it's like there are not! I was thinking that it was because of the emulator, but i tried it on the phone and the result is the same. private SensorManager mSensorManager; TextView mSensorsTot,mSensorAvailables; ...... public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); // Get the texts fields of the layout and setup to invisible mSensorsTot = (TextView) findViewById(R.id.sensoritot); mSensorAvailables = (TextView) findViewById(R.id.sensoridisponibili); // Get the SensorManager mSensorManager= (SensorManager) getSystemService(SENSOR_SERVICE); // List of Sensors Available List<Sensor> msensorList = mSensorManager.getSensorList(SensorManager.SENSOR_ALL); // Print how may Sensors are there mSensorsTot.setText(msensorList.size()+" "+this.getString(R.string.sensors)+"!"); // Print each Sensor available using sSensList as the String to be printed String sSensList = new String(""); Sensor tmp; int x,i; for (i=0;i<msensorList.size();i++){ tmp = msensorList.get(i); sSensList = " "+sSensList+tmp.getName(); // Add the sensor name to the string of sensors available } // if there are sensors available show the list if (i>0){ sSensList = getString(R.string.sensors)+":"+sSensList; mSensorAvailables.setText(sSensList); } } Thank's Valerio From Italy :)
