  • resultCode is always 0

    - by Aaron T
    I'm trying to get the resultCode to be OK inside my onActivityResult function. However, it keeps coming back as 0. I have spent several days on this, and can't figure out why it doesn't work. Here's my code. If anybody can help me, I'll be very grateful, Thanks. My Activity1 class: private class MyTask extends AsyncTask<String, Void, String> { @Override protected String doInBackground(String... urls) { // process return result; } @Override protected void onPostExecute(String result) { Intent i = new Intent(Activity1.this, Activity2.class); i.putExtra("Value1", "This value one for ActivityOne "); i.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK); startActivityForResult(i, REQUEST_CODE); textView.setText(result); } } @Override protected void onActivityResult(int requestCode, int resultCode, Intent data) { if (resultCode == RESULT_OK && requestCode == REQUEST_CODE) { // do something } } My Activity 2 class: @Override public void finish() { Intent data = new Intent(); data.putExtra("returnKey1", "return 1"); setResult(RESULT_OK, data); super.finish(); } My manifest: <application android:icon="@drawable/icon" android:label="@string/app_name"> <activity android:name=".Activity1" android:label="@string/app_name"> <intent-filter> <action android:name="android.intent.action.MAIN" /> <category android:name="android.intent.category.LAUNCHER" /> </intent-filter> </activity> <activity android:name=".Activity2" android:label="@string/app_dialog_name" android:launchMode="singleTop" android:excludeFromRecents="true" android:taskAffinity="" android:theme="@android:style/Theme.Dialog"> </activity> </application>

  • Dynamic web widget

    - by user1824996
    My vendor offers a widget creation service where I can login to their page, set initial values of a search form, after the save button is clicked, I can copy & paste the script code on my website to display a product search result widget. I am thinking to change this static widget to a dynamic one. Since my programming knowledge is limited, can experts tell me if it's possible to login https remotely (using cURL) and set search form values equal to values on my page (every time my page content changes, it will change the form value), then save the form. So the widget script I pasted on my page will always be refreshed to new search result. So the issue will involve cross domain, form submission & server/browser communication. I know a little jQuery, PHP, Ajax, cURL but so far I stuck with just having an idea but not really sure how to implement it.

  • Huh? JDK not found? (on Windows 7 64-bit)

    - by Android Eve
    I am setting up a development environment for the latest Android 2.3 on a fresh install of Windows 7 64-bit. I first installed the 64-bit JDK 6 (jdk-6u23-windows-x64.exe). Then, I installed 64-bit Eclipse Classic 3.6 (eclipse-SDK-3.6.1-win32-x86_64.zip). Then, I proceed to install the Android SDK Starter Package: installer_r08-windows.exe. But... upon start it says: "Java SE Development Kit (JDK) not found." Why? I just installed it. Is this a mismatch between 32-bit and 64-bit? How do I solve this? Update (1): I tried setting the %JAVA_HOME% environment variable, as well as setting the Installed JREs in Eclipse, as suggested below. None of these solved the problem. It appears that I am not the only experiencing the problem, as this thread suggests: http://stackoverflow.com/questions/1919340/android-sdk-setup-under-windows-7-pro-64-bit I wonder whether there is a 64-bit version of the Android SDK. Update (2): I used the zip version instead (android-sdk_r08-windows.zip), ran android.bat, updated all SDK packages, and installed the ADT plugin (8.0.1), not before having to check: 'Contact all update sites during install to find required software'. We'll see how this goes... Update (3): It worked! (going to accept @bubu's answer shortly) -- but why doesn't the emulator include the HelloAndroid app when I run it (Ctrl+F11) from Eclipse?

    - by user1796310
    I'm trying to create android apps which able sending data through wifi connection to my laptop Apache Server and MySQL database. I use the samsung galaxy tab 10.1 as my mobile device. and the protocol i used is HttpGet or HttpPost. And i use XAMPP( with Apache& SQL) to do the server and process the php. But, due to android cannot detect adhoc network from laptop, i use Virtual Router ( for window 7) to create virtual access point and make the tablet able connect to my laptop. But the problem is: [1] in my apps (client-android), where the httpget or httppost to which url? localhost in my laptop- 127.0.0.1 or localhost in android 10.0.0.1? or the ip address of the virtual router? [2]so, if i want access from android to the localhost(laptop-Apache) to call the php to run? which port? which ip address /url that i need to put in android apps(httpget)? and do i need to modify anything in httpconfig for XAMPP? thanks alot.

  • HTC Android Fails to mount- Mount from computer?

    - by Ben Franchuk
    I Have an HTC Incredible S (S-Off, Rooted, ViperVIVO 1.3.0 ICS) that has seemingly ceased to posses the ability to mount its SD Storage to my computer. For whatever reason, whenever I plug in my device to transfer files from computer to phone and vice versa, the computer, for some reason, cannot actually aces the phone. I get prompted with a window on my phone when I first plug it in, asking me which mode I want to put the device into (Charge mode, tether mode, etc.), and even if I select the "Disk Drive" function, the phone still cannot successfully mount to my computer. The phone itself unmounts itself from the SD and says that the computer is connected, but again, it doesn't work. Is there any way to force mount the device from my computer- either via command or otherwise? This should help in that if I unmount the SD from the phone I should be able to mount it to my computer, from my computer, Correct?

  • Android tethering via bluetooth keeps disconnecting

    - by Ian
    I'm currently using a Google Nexus tablet tethered via Bluetooth to a Samsung S3 for internet. Two things are annoying me. First, if I take the phone away from the tablet (go out for lunch), the tablet disconnects and has to be manually reconnected. Is there a way to have that happen automatically? Second, Bluetooth tethering, i.e. the internet sharing part needs to be switched on each time the bluetooth is switched on (or perhaps just after power cycling) on the S3. Is there no way to have that default to on? Thanks

  • Lost current user (shutdown/logoff) widget after upgrading to Ubuntu 10.04

    - by xyzman
    I've upgraded to 10.04 from 9.10. Everything went fine until I've rebooted. After reboot, I've received some message about status panel and being sleepy, dismissed it. However, I haven't seen the user widget on Gnome Panel since that. This image shows which widget I'm talking about. If some one has any ideas about how it's called properly, please share. http://img237.imageshack.us/img237/8274/sampleyu.jpg Anyway, the question is, how do I turn this panel (and ability to shut my system down without resorting to console) back?

  • Manager/Container class vs static class methods

    - by Ben
    Suppose I a have a Widget class that is part of a framework used independently by many applications. I create Widget instances in many situations and their lifetimes vary. In addition to Widget's instance specified methods, I would like to be able to perform the follow class wide operations: Find a single Widget instance based on a unique id Iterate over the list of all Widgets Remove a widget from the set of all widgets In order support these operations, I have been considering two approaches: Container class - Create some container or manager class, WidgetContainer, which holds a list of all Widget instances, support iteration and provides methods for Widget addition, removal and lookup. For example in C#: public class WidgetContainer : IEnumerable<Widget { public void AddWidget(Widget); public Widget GetWidget(WidgetId id); public void RemoveWidget(WidgetId id); } Static class methods - Add static class methods to Widget. For example: public class Widget { public Widget(WidgetId id); public static Widget GetWidget(WidgetId id); public static void RemoveWidget(WidgetId id); public static IEnumerable<Widget AllWidgets(); } Using a container class has the added problem of how to access the container class. Make it a singleton?..yuck! Create some World object that provides access to all such container classes? I have seen many frameworks that use the container class approach, so what is the general consensus?

  • How to use Android's CacheManager?

    - by punnie
    I'm currently developing an Android application that fetches images using http requests. It would be quite swell if I could cache those images in order to improve to performance and bandwidth use. I came across the CacheManager class in the Android reference, but I don't really know how to use it, or what it really does. I already scoped through this example, but I need some help understanding it: /core/java/android/webkit/gears/ApacheHttpRequestAndroid.java Also, the reference states: "Network requests are provided to this component and if they can not be resolved by the cache, the HTTP headers are attached, as appropriate, to the request for revalidation of content." I'm not sure what this means or how it would work for me, since CacheManager's getCacheFile accepts only a String URL and a Map containing the headers. Not sure what the attachment mentioned means. An explanation or a simple code example would really do my day. Thanks! Update Here's what I have right now. I am clearly doing it wrong, just don't know where. public static Bitmap getRemoteImage(String imageUrl) { URL aURL = null; URLConnection conn = null; Bitmap bmp = null; CacheResult cache_result = CacheManager.getCacheFile(imageUrl, new HashMap()); if (cache_result == null) { try { aURL = new URL(imageUrl); conn = aURL.openConnection(); conn.connect(); InputStream is = conn.getInputStream(); cache_result = new CacheManager.CacheResult(); copyStream(is, cache_result.getOutputStream()); CacheManager.saveCacheFile(imageUrl, cache_result); } catch (Exception e) { return null; } } bmp = BitmapFactory.decodeStream(cache_result.getInputStream()); return bmp; }

  • Scrolling a Canvas smoothly in Android

    - by prepbgg
    I'm new to Android. I am drawing bitmaps, lines and shapes onto a Canvas inside the OnDraw(Canvas canvas) method of my view. I am looking for help on how to implement smooth scrolling in response to a drag by the user. I have searched but not found any tutorials to help me with this. The reference for Canvas seems to say that if a Canvas is constructed from a Bitmap (called bmpBuffer, say) then anything drawn on the Canvas is also drawn on bmpBuffer. Would it be possible to use bmpBuffer to implement a scroll ... perhaps copy it back to the Canvas shifted by a few pixels at a time? But if I use Canvas.drawBitmap to draw bmpBuffer back to Canvas shifted by a few pixels, won't bmpBuffer be corrupted? Perhaps, therefore, I should copy bmpBuffer to bmpBuffer2 then draw bmpBuffer2 back to the Canvas. A more straightforward approach would be to draw the lines, shapes, etc. straight into a buffer Bitmap then draw that buffer (with a shift) onto the Canvas but so far as I can see the various methods: drawLine(), drawShape() and so on are not available for drawing to a Bitmap ... only to a Canvas. Could I have 2 Canvases? One of which would be constructed from the buffer bitmap and used simply for plotting the lines, shapes, etc. and then the buffer bitmap would be drawn onto the other Canvas for display in the View? I should welcome any advice! Answers to similar questions here (and on other websites) refer to "blitting". I understand the concept but can't find anything about "blit" or "bitblt" in the Android documentation. Are Canvas.drawBitmap and Bitmap.Copy Android's equivalents?

  • Making a Text-To-Speech Wrapper in Android

    - by John Montgomery
    I am attempting to create a wrapper class for Google Android's Text-To-Speech functionality. However, I'm having trouble finding a way to have the system pause until after the onInit function has finished. Attached at the bottom is something of a solution I created based on what I found here: http://stackoverflow.com/questions/1160876/android-speech-how-can-you-read-text-in-android However, this solution does not seem to work. Any thoughts on why this might not be working, or what would be a good idea in order to make sure that any Speak() calls happen after my onInit() call? public class SpeechSynth implements OnInitListener { private TextToSpeech tts; static final int TTS_CHECK_CODE = 0; private int ready = 0; private ReentrantLock waitForInitLock = new ReentrantLock(); SpeechSynth( Activity screen ) { ready = 0; tts = new TextToSpeech( screen, this ); waitForInitLock.lock(); } public void onInit(int status) { if (status == TextToSpeech.SUCCESS) { ready = 1; } waitForInitLock.unlock(); } public int Speak( String text ) { if( ready == 1 ) { tts.speak(text, TextToSpeech.QUEUE_ADD, null); return 1; } else { return 0; } } } I have been able to make it so that I can pass a string of text through the constructor, then have it played in the onInit() function. However, I would really like to avoid having to destroy and re-create the whole text-to-speech engine every time I need to have my program say something different.

  • Android: Creating a Scrollable Layout

    - by MD
    I'm trying to create a "scrollable" layout in Android. Even using developers.android.com, though, I feel a little bit lost at the moment. I'm somewhat new to Java, but not so much that I feel I should be having these issues--being new to Android is the bigger problem right now. The layout I'm trying to create should scroll in a sort of a "grid". I THINK what I'm looking for is the Gallery view, but I'm really lost as to how to implement it at the moment. I want it to "snap" to center the frame, like in the actual Gallery application. Essentially, if I had a photo gallery of 9 pictures, the idea is to scroll between them up/down AND side to side, in a 3x3 manner. Doesn't need to dynamically adjust, or anything like that, I just want a grid I can scroll through. I'm also not asking for anyone to give me explicit code for it--I'm trying to learn, more than anything. But pointing me in the right direction for helpful layout programming resources would be greatly appreciated, and confirming if it's a Gallery view I'm looking for would also be really helpful. EDIT: To clarify, the goal is to have ONE item on screen at a time. If you scroll between one item and the next, the previous one leaves the screen, and the new one snaps into place. So if it were a photo gallery, each spot on the grid would take up the entire screen size, approximately, and would be flung out of the viewable area when you slide across to the next photo, in either direction. (Photos are just an example for illustration purposes)

  • Storing data on SD Card in Android

    - by BBoom
    Using the guide at Android Developers (http://developer.android.com/guide/topics/data/data-storage.html) I've tried to store some data to the SD-Card. This is my code: // Path to write files to String path = Environment.getExternalStorageDirectory().getAbsolutePath() + "/Android/data/"+ctxt.getString(R.string.package_name)+"/files/"; String fname = "mytest.txt"; // Current state of the external media String extState = Environment.getExternalStorageState(); // External media can be written onto if (extState.equals(Environment.MEDIA_MOUNTED)) { try { // Make sure the path exists boolean exists = (new File(path)).exists(); if (!exists){ new File(path).mkdirs(); } // Open output stream FileOutputStream fOut = new FileOutputStream(path + fname); fOut.write("Test".getBytes()); // Close output stream fOut.flush(); fOut.close(); } catch (IOException ioe) { ioe.printStackTrace(); } When I create the new FileOutputStream I get a FileNotFound exception. I have also noticed that "mkdirs()" does not seem to create the directory. Can anyone tell me what I'm doing wrong? I'm testing on an AVD with a 2GB sd card and "hw.sdCard: yes", the File Explorer of DDMS in Eclipse tells me that the only directory on the sdcard is "LOST.DIR".

  • android compile error: could not reserve enough space for object heap

    - by moonlightcheese
    I'm getting this error during compilation: Error occurred during initialization of VM Could not create the Java virtual machine. Could not reserve enough space for object heap What's worse, the error occurs intermittently. Sometimes it happens, sometimes it doesn't. It seems to be dependent on the amount of code in the application. If I get rid of some variables or drop some imported libraries, it will compile. Then when I add more to it, I get the error again. I've included the following sources into the application in the [project_root]/src/ directory: org.apache.httpclient (I've stripped all references to log4j from the sources, so don't need it) org.apache.codec (as a dependency) org.apache.httpcore (dependency of httpclient) and my own activity code consisting of nothing more than an instance of HttpClient. I know this has something to do with the amount of memory necessary during compile time or some compiler options, and I'm not really stressing my system while i'm coding. I've got 2GB of memory on this Core Duo laptop and windows reports only 860MB page file usage (haven't used any other memory tools. I should have plenty of memory and processing power for this... and I'm only compiling some common http libs... total of 406 source files. What gives? edit (4/30/2010-18:24): Just compiled some code where I got the above stated error. I closed some web browser windows and recompiled the same exact code with no edits and it compiled with no issue. this is definitely a compiler issue related to memory usage. Any help would be great.... because I have no idea where to go from here. Android API Level: 5 Android SDK rel 5 JDK version: 1.6.0_12 Sorry I had to repost this question because regardless of whether I use the native HttpClient class in the Android SDK or my custom version downloaded from apache, the error still occurs.

  • 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.

  • Android Scaled Drawing to ImageView

    - by user329999
    Newbie question, so there's probably a simple answer to this problem. I'm drawing some simple shapes using canvas.drawCircle(), canvas.drawLine() etc. I originally copied the code from: http://developer.android.com/resources/samples/ApiDemos/src/com/example/android/apis/graphics/DrawPoints.html Which extends a View and draws directly to a canvas. It doesn't load a pre-drawn bitmap because I need my application to turn data into a drawing and the user will enter the data. My changes work, but the drawing is too small (or big) and doesn't fill the screen using all the available screen. Ideally I'd rather use something like an ImageView in .XML like so: If that's possible. The documentation seems to imply that I want to set the scaleType as shown in the above .XML which seems like the simple way to do this. If using an ImageView in .XML is a good idea, then I'm lost on how to draw to the ImageView and could use some guidance on doing that task. If that won't work, then I'll need to do some more thinking about how to get my drawing scaled on the screen and basically I'm lazy and would rather have Android do the work for me. Feel free to suggest some other way that's completely different is this is the wrong solution path. :) Thanks.
