  • Android Eclipse Error "Android Packaging Problem"

    - by Peter Delaney
    Hello; I am getting an error in my Problems tab for my Android Project in Eclipse. The error is "Android Packaging Problem" with an Unknown location. Unknown Error NullPointerException I cannot determine what this problem is. My project was working a few hours ago. The only change I made was to add a public interface ITrackDao to my project and implement it. There are no errors associated with this. I am not even sure where to begin to look. I cannot launch the application. Can someone give me an idea on what area I can look into? Thanks Peter

  • Android Permission Issue android.permission.READ_CONTACTS

    - by jkmcgee
    Hello, All I am trying to do is read a contact off of my emulator and display it to the screen. I can't seem to resolve this error. Both of my packages (com.msi.ibm.tutorial and .MobileServiceCallContacts) have the permission READ_CONTACTS set in their manifest xml files. So any ideas as to what I've got wrong ? Here is the error message from eclipse console if it helps, it's not helping me, but I'm a little rusty at this and completely new to Android development. MobileServiceCallContacts]Starting activity com.msi.ibm.tutorial.MobileServiceCallContacts on device MobileServiceCallContacts]ActivityManager: Starting: Intent { cmp=com.msi.ibm.tutorial/.MobileServiceCallContacts } MobileServiceCallContacts]ActivityManager: java.lang.SecurityException: Permission Denial: starting Intent { flg=0x10000000 cmp=com.msi.ibm.tutorial/.MobileServiceCallContacts } from null (pid=-1, uid=-1) requires android.permission.READ_CONTACTS

  • Android question - how to prep 100 images to be shown via Fling/Swipe?

    - by fooyee
    I'm totally new to this, been tinkering around for a week. Came up with a simple image viewer app for 2 images. Feature: Left and right swipes will switch the images. Dead simple. What i'd like to do: Have up to 100 images. note: All my images are in my res/drawable folder. They're named image1.png to image100.png I obviously don't want to do: ImageView i = new ImageView(this); i.setImageResource(R.drawable.image1); viewFlipper.addView(i); ImageView i2 = new ImageView(this); i2.setImageResource(R.drawable.image2); viewFlipper.addView(i2); ImageView i3 = new ImageView(this); i3.setImageResource(R.drawable.image3); viewFlipper.addView(i3); all the way to i100. how do I make this into a loop, which is flexible and reads everything from the drawable folder ( and not be limited to 100 images)? source: public class ImageViewTest extends Activity { private static final String LOGID = "CHECKTHISOUT"; private static final int SWIPE_MIN_DISTANCE = 120; private static final int SWIPE_MAX_OFF_PATH = 250; private static final int SWIPE_THRESHOLD_VELOCITY = 200; private GestureDetector gestureDetector; View.OnTouchListener gestureListener; private Animation slideLeftIn; private Animation slideLeftOut; private Animation slideRightIn; private Animation slideRightOut; private ViewFlipper viewFlipper; String message = "Initial Message"; /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); //Set up viewflipper viewFlipper = new ViewFlipper(this); ImageView i = new ImageView(this); i.setImageResource(R.drawable.sample_1); ImageView i2 = new ImageView(this); i2.setImageResource(R.drawable.sample_2); viewFlipper.addView(i); viewFlipper.addView(i2); //set up animations slideLeftIn = AnimationUtils.loadAnimation(this, R.anim.slide_left_in); slideLeftOut = AnimationUtils.loadAnimation(this, R.anim.slide_left_out); slideRightIn = AnimationUtils.loadAnimation(this, R.anim.slide_right_in); slideRightOut = AnimationUtils.loadAnimation(this, R.anim.slide_right_out); //put up a brownie as a starter setContentView(viewFlipper); gestureDetector = new GestureDetector(new MyGestureDetector()); } public class MyGestureDetector extends SimpleOnGestureListener { @Override public boolean onFling(MotionEvent e1, MotionEvent e2, float velocityX, float velocityY) { try { if (Math.abs(e1.getY() - e2.getY()) > SWIPE_MAX_OFF_PATH) return false; // right to left swipe if(e1.getX() - e2.getX() > SWIPE_MIN_DISTANCE && Math.abs(velocityX) > SWIPE_THRESHOLD_VELOCITY) { Log.v(LOGID,"right to left swipe detected"); viewFlipper.setInAnimation(slideLeftIn); viewFlipper.setOutAnimation(slideLeftOut); viewFlipper.showNext(); setContentView(viewFlipper); } // left to right swipe else if (e2.getX() - e1.getX() > SWIPE_MIN_DISTANCE && Math.abs(velocityX) > SWIPE_THRESHOLD_VELOCITY) { Log.v(LOGID,"left to right swipe detected"); viewFlipper.setInAnimation(slideRightIn); viewFlipper.setOutAnimation(slideRightOut); viewFlipper.showPrevious(); setContentView(viewFlipper); } } catch (Exception e) { // nothing } return false; } } // This doesn't work @Override public boolean onTouchEvent(MotionEvent event) { if (gestureDetector.onTouchEvent(event)){ Log.v(LOGID,"screen touched"); return true; } else{ return false; } } }

  • Android spinner inside a custom control - OnItemSelectedListener does not trigger

    - by Idan
    I am writing a custom control that extends LinearLayout. Inside that control I am using a spinner to let the user select an item from a list. The problem I have is that the OnItemSelectedListener event does not fire. When moving the same code to an Activity/Fragment all is working just fine. I have followed some answers that was given to others asking about the same issue, and nothing helped. still the event does not fire. This is my code after I followed the answers that suggested to put the spinner inside my layout XML instead of by code. I am getting the same result when I try to just "new Spinner(ctx)"... layout XML: <Spinner android:id="@+id/accSpinner" android:layout_width="0dip" android:layout_height="0dip" /> Initialization function of the control (called on the control constructor): private void init() { LayoutInflater layoutInflater = LayoutInflater.from(mContext); mAccountBoxView = layoutInflater.inflate(R.layout.control_accountselector, null); mTxtAccount = (TextView)mAccountBoxView.findViewById(R.id.txtAccount); mSpinner = (Spinner)mAccountBoxView.findViewById(R.id.accSpinner); mAccountBoxView.setOnClickListener(new OnClickListener() { @Override public void onClick(View v) { mSpinner.performClick(); } }); setSpinner(); addView(mAccountBoxView); } private void setSpinner() { ArrayAdapter<String> dataAdapter = new ArrayAdapter<String>(mContext, android.R.layout.simple_spinner_item, mItems); dataAdapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item); mSpinner.setAdapter(dataAdapter); mSpinner.setOnItemSelectedListener(new OnItemSelectedListener() { @Override public void onItemSelected(AdapterView<?> parent, View view, int position, long id) { String selectedItem = mItems.get(position); handleSelectedItem(selectedItem); } @Override public void onNothingSelected(AdapterView<?> parent) { } }); } The spinner raises just fine when i touch my control and the list of items is there as it should. When I click an item the spinner closes but I am never getting to onItemSelected nor onNothingSelected.. Any ideas?

  • Android: duplicate items in ListVew. Maybe getView() called too many times?

    - by gonzobrains
    Hi, I am trying to create a simple program which displays a "shopping cart" list of items, along with a few buttons below it to manage the cart. The biggest problem is that items are getting duplicate entries in the list view. That is, for every item I want to enter I see it appear two times in the list view. What's the problem? Also, the scrollable area of my cart is not big enough. How do I set it so that it is bigger but I can still see my buttons? Perhaps I should put the buttons above the cart? Here is my shopping cart's layout XML: Here is the layout for individual row items: <LinearLayout android:orientation="vertical" android:layout_width="0dip" android:layout_weight="1" android:layout_height="fill_parent"> <TextView android:id="@+id/BookTitle" android:layout_width="fill_parent" android:layout_height="0dip" android:layout_weight="1" android:singleLine="true" android:gravity="center_vertical" / <TextView android:id="@+id/BookPrice" android:layout_width="fill_parent" android:layout_height="0dip" android:layout_weight="1" android:singleLine="true" android:ellipsize="marquee" / Thanks, gb

    I am developing an Android App that uses the Google APIs Client Library for Java version 1.12.0. I have added the jar files to the /libs folder (and not to a new /lib folder). I get the following error: Dx trouble processing "javax/xml/namespace/QName.class": Ill-advised or mistaken usage of a core class (java.* or javax.*) when not building a core library.

  • Android: Why my user Interface does not get drawn when I Inflate the resource layout file?

    - by Einiosaurus
    First of all, I'm a newbie on Android programming, so please be detailed in your answers. I have a layout main.xml file with format similar to <?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android = "http://schemas.android.com/apk/res/android" android:orientation = "vertical" android:layout_width = "fill_parent" android:layout_height = "fill_parent"> <LinearLayout xmlns:android = "http://schemas.android.com/apk/res/android" android:orientation = "horizontal"   android:layout_width = "fill_parent" android:layout_height = "fill_parent"> <EditText android:id="@+id/a" android:layout_width="fill_parent" android:layout_height="wrap_content" /> <TextView android:id="@+id/xSquared" android:layout_width = "fill_parent" android:layout_height = "wrap_content" android:text = "@string/equationPart1" /> </LinearLayout> <LinearLayout ... </LinearLayout> </LinearLayout> In my Java source file, I inflate the UI using command: setContentView(R.layout.main); public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); } However, when I run the emulator, the UI does not show up like what I expect. Instead, it just display a simple EditText text box. I wonder what is going wrong. Is it because I put a layout inside another layout? I don't think there is any problem with that right?

  • Android - How to circular zoom/magnify part of image?

    - by IZI_Shadow_IZI
    I am trying to allow the user to touch the image and then basically a cirular magnifier will show that will allow the user to better select a certain area on the image. When the user releases the touch the magnified portion will dissapear. This is used on several photo editing apps and I am trying to implement my own version of it. The code I have below does magnify a circular portion of the imageview but does not delete or clear the zoom once I release my finger. I currently set a bitmap to a canvas using canvas = new Canvas(bitMap); and then set the imageview using takenPhoto.setImageBitmap(bitMap); I am not sure if I am going about it the right way. The onTouch code is below: zoomPos = new PointF(0,0); takenPhoto.setOnTouchListener(new OnTouchListener() { @Override public boolean onTouch(View v, MotionEvent event) { int action = event.getAction(); switch (action) { case MotionEvent.ACTION_DOWN: zoomPos.x = event.getX(); zoomPos.y = event.getY(); matrix.reset(); matrix.postScale(2f, 2f, zoomPos.x, zoomPos.y); shader.setLocalMatrix(matrix); canvas.drawCircle(zoomPos.x, zoomPos.y, 20, shaderPaint); takenPhoto.invalidate(); break; case MotionEvent.ACTION_MOVE: zoomPos.x = event.getX(); zoomPos.y = event.getY(); matrix.reset(); matrix.postScale(2f, 2f, zoomPos.x, zoomPos.y); canvas.drawCircle(zoomPos.x, zoomPos.y, 20, shaderPaint); takenPhoto.invalidate(); break; case MotionEvent.ACTION_UP: //clear zoom here? break; case MotionEvent.ACTION_CANCEL: break; default: break; } return true; } });

  • Why do apps from Android 2.1 stop working with 2.2?

    - by poeschlorn
    Hi guys, I've just updated my nexus one to 2.2. Now all of my (own and some from the market) apps throw exceptions and were closed. It's weird, in the app I'm developing atm, there it displays only my start page with buttons, but when I tap on one button to fire an intent to another activity my app gets closed with an exception. Yesterday before the update everything worked fine. The same thing in my emulator: I have two devices, one with API level 7 and one with level 8. Level 7 worked fine, but level 8 killed my app :( What is the problem and how can I solve this? I'm desperatly trying to get it working again :( I hope someone can help me fixing this

  • Using a cell phone as a PC remote control

    - by Mahmoud Hossam
    I have a sony ericsson phone that can control any PC using bluetooth, as long as it has permission to do so, of course. It doesn't require any server software of any kind, it just works out of the box with any PC (or mac) that is bluetooth enabled. Is there any program I could use that has the same functionality? I don't want to install anything on the PC, I just want to be able to use the program installed on the phone. I prefer Java ME/Android/Symbian apps, I don't have an iPhone.

  • Communication software wanted: email, sms, IM, phone calls [closed]

    - by user63835
    I am searching for a software solution that integrates / unifies my communication. I use email, instant messaging, SMS and phone. I would like to get all emails, SMS, instant messaging dialogs and meta-data about phone calls into one application. Important is that I can access all past communication with one application. There should be a global address-book to map the communication data to persons or organizations. I want all the communication data in one place to access and backup it easily. The software solution is not required to be multi-user application or server application. It is just for one user (me) only, but server or multi-user applications are not excluded. I may run it on a server hardware. It should run on Linux (Lubuntu / Ubuntu prefered). Free and OpenSource software is prefered. It would be nice if I could perform new communication (like writing a new email, sms, etc.) with one application, but that is not a must have requirement. I could also work with different applications dedicated for different types of communication like IM-application for IM and email-application for email, if all that communication data from the specialized applications will be delivered to one single place where I can access and backup it. I have an android phone and currently I am using Google contacts as the address-book. In the long term this may change, to get back the control over my data. I did some Internet search but did not find a nice solution, yet. If I am looking for unified messaging and unified communication, am I on the right track? The current Thunderbird version has IM functionality integrated. Did not try it, yet. For SMS it may be possible to use an app to send every SMS (incoming and outgoing) as an email, but I am not sure if those SMS-emails can be mapped to an address-book contact. I don't remember exactly, but isn't there a Google android app (I think Google voice) integrating SMS into google services? But in Germany this function has not been released, yet. Maybe a groupware solution would solve the requirements, but I don't have much experience with it. As communication possibilites are groing, I am woundering that there seems to be such a big gap of solutions. I can't believe I am the only one who would like solution, better integrating all the communication channels more easily. If you know a software solution that solves these requirements (partly) I would be glad if you tell me about it. Thanks in advance.

  • Cannot mount Android phone in Ubuntu and sync with Banshee

    I can't get my LG Optimus One to sync with Banshee. I read somewhere that the root needs to have an empty file called '.is_audio_player'. I did that and it still doesn't mount. I ran dmesg however and it appears that the card is unmounting before I even have a change to run Banshee.

  • You Don’t Need to Install a Task Manager: How to Manage Running Apps on Android

    - by Chris Hoffman
    Google Play is full of task managers for Android. These utilities can show you apps running in the background, kill running apps, and otherwise manage your apps — but you don’t need to install any third-party software to do this. We’ll show you how to quickly and easily kill and manage your running apps using only the software included with your Android phone. Third-party task managers are unnecessary and many include harmful features, like task killers.

  • Android Photosphere Viewer Application

    - by Frisbetarian
    I'm aiming to develop an android app that simply views photosphere files. It should utilize the compass to pan around the sphere when the user moves his/her phone. I'm not aiming to create photospheres via the phone's camera with it, just upload the necessary jpegs and view them. Could anyone offer any advice as to how I could go about with implementing an API that views and gives the option to manipulate photosphere files?

  • Best Platform/Engine for turn based Client/Server Android game

    - by Paradine
    I'm currently designing a turn based game for tablets. Initially for Android with porting to iOS later considered in design. I'm having trouble narrowing down the available technologies to even know where to spend my research time. I am hoping that if I explain what I am trying to achieve someone may be able to suggest a platform and/or engine. I've looked into some of the open source Engines ( http://www.cuteandroid.com/ten-open-source-android-2d-or-3d-game-engine-for-android-developers ) and some appear to handle much of what I might require - although with a higher focus on graphics than i need. Mages looks interesting although development appears to have ceased. If I could somehow leverage GoogleApps that would be excellent. Here is what I am trying to achieve: PvP turn based strategy game over internet - minimal animation and bandwidth required Players match up online using MetaGame system MatchID created on Resolution Server and Game starts Clients have 30 second countdown to select MoveString Clients sends small secure timestamped and MatchIDed MoveString to Resolution server Resolution server looks up Move String for each player, Resolves and Updates Players status in MatchID on Server Resolution server updates Client Views Repeat until victory conditions met - MatchID Closed, Rewards earned in MetaGame There will also need to be a full social and account system and metagame backend - but this could be running on separate system(s) Tablet in Offline mode would be catalog browsing and perhaps single player AI - bum I'm focusing on the Resolution Server at this point I'm not even certain if I would be looking at an Android App or a WebApp at this stage! I want a custom GUI so I guess an app - but maybe as I have little animation a WebApp might also work. Probably some combination of both. There will be very small overhead in data between client server - essentially a small text string every 30 seconds sent to the Resolution server which looks up the Effect and applies it to the Opponents string and determines some results to apply to the match. The client view is updated minimally with the results (only 5 in game Integers tracked) - perhaps triggering small animations/popups on the client to show the end result. e.g Explosion. If you have suggestions for a good technology or platform to best achieving the Resolution Server I'd love to hear. Also if you have experience with open source Engines - and could narrow down which (if any ) might be most suitable that would be a big help. Thanks in advance

  • Windows Phone 8 development on Windows 7 - is it or will be possible?

    - by Tiby
    I was trying to install Windows Phone 8 SDK on my Windows 7 machine and it hit me with the 'supported only on Windows 8' message. I actually wanted to develop Phone 7.5 apps on Visual Studio 2012, impossible thing with the 7.1 SDK, so I thought 8 SDK will do the job. As if it was not enough that the 8 SDK was controversial upon release, now that it's generally available, to me it seems like a horrible decision to make it available only for Windows 8, because in my humble opinion, no serious and sane developer will install Windows 8 ever, or at least in the near future, just because of the Metro UI. So, anyone knows any workarounds for developing Windows Phone 8 on Windows 7, or at least develop for 7.5 but using Visual Studio 2012?
