  • Activity won't start a service

    - by Marko Cakic
    I m trying to start an IntentService from the main activity of y application and it won't start. I have the service in the manifest file.

  • Dynamically changing layout

    - by LTMOD
    I have a 2 x 2 grid of buttons. Each row of 2 is wrapped in a horizontal linear layout. <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="horizontal" android:layout_width="fill_parent" android:layout_height="100dip"> <Button android:layout_weight=".5" android:id="@+id/btn1" android:layout_width="fill_parent" android:layout_height="fill_parent" android:layout_gravity="center_vertical|center_horizontal" android:padding="5dip" android:layout_margin="2dip"> </Button> <Button android:layout_weight=".5" android:id="@+id/btn2" android:layout_width="fill_parent" android:layout_height="fill_parent" android:padding="5dip" android:layout_margin="2dip"> </Button> At times I want to show all 4 buttons, and other times, I show the top 2 only, and sometimes, I need to show 2 on top, and one on the bottom. I would like to center the bottom one, but can't seem to accomplish this. In my code, I call btn4.setVisibility(8); //8 = GONE, which makes my 4th button disappear, but then btn3 ends up filling the entire layout. What I would like it to do instead is center itself within the layout at its correct width / height. I'm a bit new to this, so any help is greatly appreciated. Thanks in advance!

  • Bluetooth RFCOMM / SDP connection to a RS232 adapter in android

    - by ThePosey
    Hello All, I am trying to use the Bluetooth Chat sample API app that google provides to connect to a bluetooth RS232 adapter hooked up to another device. Here is the app for reference: http://developer.android.com/resources/samples/BluetoothChat/index.html And here is the spec sheet for the RS232 connector just for reference: http://serialio.com/download/Docs/BlueSnap-guide-4.77_Commands.pdf Well the problem is that when I go to connect to the device with: mmSocket.connect(); (BluetoothSocket::connect()) I always get an IOException error thrown by the connect() method. When I do a toString on the exception I get "Service discovery failed". My question is mostly what are the cases that would cause an IOException to get thrown in the connect method? I know those are in the source somewhere but I don't know exactly how the java layer that you write apps in and the C/C++ layer that contains the actual stacks interface. I know that it uses the bluez bluetooth stack which is written in C/C++ but not sure how that ties into the java layer which is what I would think is throwing the exception. Any help on pointing me to where I can try to dissect this issue would be incredible. Also just to note I am able to pair with the RS232 adapter just fine but I am never able to actually connect. Here is the logcat output for more reference: I/ActivityManager( 1018): Displayed activity com.example.android.BluetoothChat/.DeviceListActivity: 326 ms (total 326 ms) E/BluetoothService.cpp( 1018): stopDiscoveryNative: D-Bus error in StopDiscovery: org.bluez.Error.Failed (Invalid discovery session) D/BluetoothChat( 1729): onActivityResult -1 D/BluetoothChatService( 1729): connect to: 00:06:66:03:0C:51 D/BluetoothChatService( 1729): setState() STATE_LISTEN - STATE_CONNECTING E/BluetoothChat( 1729): + ON RESUME + I/BluetoothChat( 1729): MESSAGE_STATE_CHANGE: STATE_CONNECTING I/BluetoothChatService( 1729): BEGIN mConnectThread E/BluetoothService.cpp( 1018): stopDiscoveryNative: D-Bus error in StopDiscovery: org.bluez.Error.Failed (Invalid discovery session) E/BluetoothEventLoop.cpp( 1018): event_filter: Received signal org.bluez.Device:PropertyChanged from /org/bluez/1498/hci0/dev_00_06_66_03_0C_51 I/BluetoothChatService( 1729): CONNECTION FAIL TOSTRING: java.io.IOException: Service discovery failed D/BluetoothChatService( 1729): setState() STATE_CONNECTING - STATE_LISTEN D/BluetoothChatService( 1729): start D/BluetoothChatService( 1729): setState() STATE_LISTEN - STATE_LISTEN I/BluetoothChat( 1729): MESSAGE_STATE_CHANGE: STATE_LISTEN V/BluetoothEventRedirector( 1080): Received android.bleutooth.device.action.UUID I/NotificationService( 1018): enqueueToast pkg=com.example.android.BluetoothChat callback=android.app.ITransientNotification$Stub$Proxy@446327c8 duration=0 I/BluetoothChat( 1729): MESSAGE_STATE_CHANGE: STATE_LISTEN E/BluetoothEventLoop.cpp( 1018): event_filter: Received signal org.bluez.Device:PropertyChanged from /org/bluez/1498/hci0/dev_00_06_66_03_0C_51 V/BluetoothEventRedirector( 1080): Received android.bleutooth.device.action.UUID The device I'm trying to connect to is the 00:06:66:03:0C:51 which I can scan for and apparently pair with just fine. The below is merged from a similar question which was successfully resolved by the selected answer here: How can one connect to an rfcomm device other than another phone in Android? The Android API provides examples of using listenUsingRfcommWithServiceRecord() to set up a socket and createRfcommSocketToServiceRecord() to connect to that socket. I'm trying to connect to an embedded device with a BlueSMiRF Gold chip. My working Python code (using the PyBluez library), which I'd like to port to Android, is as follows: sock = bluetooth.BluetoothSocket(proto=bluetooth.RFCOMM) sock.connect((device_addr, 1)) return sock.makefile() ...so the service to connect to is simply defined as channel 1, without any SDP lookup. As the only documented mechanism I see in the Android API does SDP lookup of a UUID, I'm slightly at a loss. Using "sdptool browse" from my Linux host comes up empty, so I surmise that the chip in question simply lacks SDP support.

  • Android: MediaPlayer gapless or seamless Video Playing

    - by John Wang
    I can play the videos fine back to back by implementing the OnCompletionListener to set the data source to a different file. No problems there. I call reset() and prepare() just fine. What I haven't been able to figure out, is how to get rid of the 1-2 second gap screen flicker between the data source change and the new video starting. The gap shows a black screen, and I haven't found any way to get around it. I've tried setting the background of the parent view to an image, but it manages to bypass that. Even if the SurfaceView is transparent (which it is by default.) I've also tried to have the multiple video files played at the same time, and switching mediaplayer's display when one ends and the other is supposed to start. The last thing I tried, was to have a second view in the background that I show temporarily while the video is "preparing" and removing it when the video is ready to start. That also wasn't very seamless. Is there any way to get rid of that gap. Running a video in a loop works wonderfully and does exactly what I want with the exception that it's looking through the same video instead of playing a different one that I pick. main.xml <?xml version="1.0" encoding="utf-8"?> <FrameLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:background="@drawable/background" android:layout_height="fill_parent"> <SurfaceView android:id="@+id/surface" android:layout_width="fill_parent" android:layout_height="fill_parent" android:layout_gravity="center"> </SurfaceView> </FrameLayout> Player.java public class Player extends Activity implements OnCompletionListener, MediaPlayer.OnPreparedListener, SurfaceHolder.Callback { private MediaPlayer player; private SurfaceView surface; private SurfaceHolder holder; public void onCreate(Bundle b) { super.onCreate(b); setContentView(R.layout.main); surface = (SurfaceView)findViewById(R.id.surface); holder = surface.getHolder(); holder.addCallback(this); holder.setType(SurfaceHolder.SURFACE_TYPE_PUSH_BUFFERS); } public void onCompletion(MediaPlayer arg0) { File clip = new File(Environment.getExternalStorageDirectory(),"file2.mp4"); playVideo(clip.getAbsolutePath()); } public void onPrepared(MediaPlayer mediaplayer) { holder.setFixedSize(player.getVideoWidth(), player.getVideoHeight()); player.start(); } private void playVideo(String url) { try { File clip = new File(Environment.getExternalStorageDirectory(),"file1.mp4"); if (player == null) { player = new MediaPlayer(); player.setScreenOnWhilePlaying(true); } else { player.stop(); player.reset(); } player.setDataSource(url); player.setDisplay(holder); player.setOnPreparedListener(this); player.prepare(); player.setOnCompletionListener(this); } catch (Throwable t) { Log.e("ERROR", "Exception Error", t); } }

  • Write to file depending on minSdkVersion - android

    - by Simon Rosenqvist
    Hi, I have written a filewriter for my android application. It is to function on a Galaxy Tab, so my minSdkVersion has to be at least 4, so it will fill the screen. I originally started out with SdkVersion = 2 and at that point my filewriter worked perfectly. Changing the SdkVersion to 4 introduced the problem. My filewriter doesn't work anymore! The application runs fine, but a file doesn't get created. My .java file looks like this: public class HelloAndroid extends Activity { /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); TextView tv = new TextView(this); tv.setText("Hello, Android"); setContentView(R.layout.main); //definerer en knap kaldet button1 og sætter en listener på denne. Button button1 = (Button)findViewById(R.id.btnClickMe); button1.setOnClickListener(btnListener); //definerer en knap kaldet button2 og sætter en listener på denne. Button button2 = (Button)findViewById(R.id.btnClickMe2); button2.setOnClickListener(btnListener2); } //en variabel af typen 'long' deklæres og kaldes tid1. public long time1; private OnClickListener btnListener = new OnClickListener() { public void onClick(View v) { //Når der klikkes på button1 gemmes et tal i variablen tid1. time1 = System.currentTimeMillis(); } }; //en variabel af typen 'long' deklæres og kaldes tid2. public long time2; // en variabel af typen 'string' deklæres og kaldes tid: public String string1 = "time:"; private OnClickListener btnListener2 = new OnClickListener() { public void onClick(View v) { //Når der klikkes på button2 gemmes et tal i variablen tid2. time2 = System.currentTimeMillis(); // Herefter oprettes en fil kaldet "file.txt". try{ File file = new File(Environment.getExternalStorageDirectory(), "file.txt"); file.createNewFile(); BufferedWriter writer = new BufferedWriter(new FileWriter(file,true)); //string1 og tid2-tid1 skrives til filen. tid2-tid1 giver den tid der går fra der er trykket på den ene knap til den anden i millisekunder. writer.write(string1 + "\t" + (time2-time1)); writer.newLine(); writer.flush(); writer.close(); } catch (IOException e) { e.printStackTrace(); } } }; } And my manifest.xml looks like this: <?xml version="1.0" encoding="utf-8"?> <application android:icon="@drawable/icon" android:label="@string/app_name"> <activity android:name=".HelloAndroid" android:label="@string/app_name"> <intent-filter> <action android:name="android.intent.action.MAIN" /> <category android:name="android.intent.category.LAUNCHER" /> </intent-filter> </activity> </application> Why does my filewriter not work with minSdkVersion 2? Do i have to make a new filewriter? or what to do? Sorry for the messy code, i'm quite new to programming :)

  • How do I keep from running out of memory on graphics for an Android app?

    - by user279112
    I've been working on an Android app in Eclipse, and so far, my program hasn't really grown past midget size. However I've already run into an issue with an Out of Memory error. You see, I've been using graphics comprised solely of bitmaps and PNGs in this program, and recently, when I tried to add a little bit more functionality to the program (mainly including a few more bitmaps and causing an extra sprite to be created), it started crashing in the graphics thread's constructor - sprite's constructor. When I tracked the problem down, it turned out to be an Out of Memory error that is seemingly caused by adding too many picture files to the program and creating Drawables out of them. This would be a problem, as I really don't have that many picture resources worked into that program...maybe 20 or so. I haven't even started to include sound yet. These images aren't all that fancy. My questions are this: 1) Are programs for the Android phone really that limited on how much memory they can employ, or is it probably something other than the 20-30 resource pictures causing that error? 2) If the memory for Android apps is so awful it can't even handle 20-30 picture resources being loaded into Drawables that exist at the same time, then how in the world are you supposed to make decent graphics and sound for that thing? Thanks.

  • Which Android hardware devices should I test on? [closed]

    - by Tchami
    Possible Duplicate: What hardware devices do you test your Android apps on? I'm trying to compile a list of Android hardware devices that it would make sense to buy and test against if you want to target an as broad audience as possible, while still not buying every single Android device out there. I know there's a lot of information regarding screen sizes and Android versions available elsewhere, but: when developing for Android it's not terribly useful to know if the screen size of a device is 480x800 or 320x240, unless you feel like doing the math to convert that into Android "units" (i.e. small, normal, large or xlarge screens, and ldpi, mdpi, hdpi or xhdpi densities). Even knowing the dimensions of a device, you cannot be sure of the actual Android units as there's some overlap, see Range of screens supported in the Android documentation Taking into account the distribution of Platform versions and Screen Sizes and Densities, below is my current list based on information from the Wikipedia article on Comparison of Android devices. I'm fairly sure the information in this list is correct, but I'd welcome any suggestions/changes. Phones | Model | Android Version | Screen Size | Density | | HTC Wildfire | 2.1/2.2 | Normal | mdpi | | HTC Tattoo | 1.6 | Normal | mdpi | | HTC Hero | 2.1 | Normal | mdpi | | HTC Legend | 2.1 | Normal | mdpi | | Sony Ericsson Xperia X8 | 1.6/2.1 | Normal | mdpi | | Motorola Droid | 2.0-2.2 | Normal | hdpi | | Samsung Galaxy S II | 2.3 | Normal | hdpi | | Samsung Galaxy Nexus | 4.0 | Normal | xhdpi | | Samsung Galaxy S III | 4.0 | Normal | xhdpi | **Tablets** | Model | Android Version | Screen Size | Density | | Samsung Galaxy Tab 7" | 2.2 | Large | hdpi | | Samsung Galaxy Tab 10" | 3.0 | X-Large | mdpi | | Asus Transformer Prime | 4.0 | X-Large | mdpi | | Motorola Xoom | 3.1/4.0 | X-Large | mdpi | N.B.: I have seen (and read) other posts on SO on this subject, e.g. Which Android devices should I test against? and What hardware devices do you test your Android apps on? but they don't seem very canonical. Maybe this should be marked community wiki?

  • Button layed out using layout_toLeftOf in a RelativeLayout does not show up

    - by rodion
    Hello all, I am trying to layout a Button to the left of a TextView that is centered on the screen. My layout looks like this: <?xml version="1.0" encoding="utf-8"?> <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent" android:gravity="center"> <TextView android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="foo" android:id="@+id/center" /> <Button android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="Left button" android:layout_toLeftOf="@id/center" /> </RelativeLayout> Unfortunately, the button just does not appear. I get the following result: As you see, the button doesn't show up. It works if I use layout_toRightOf, then the button appears to the right of the TextView, just as expected. Any ideas what I am doing wrong here?

  • regex to filter all but whitelisted characters from a multi-language string

    - by jeroen
    I am trying to cleanup a string coming from a search box on a multi-language site. Normally I would use a regex like: $allowed = "-+?!,.;:\w\s"; $txt_search = preg_replace("/[^" . $allowed . "]?(.*?)[^" . $allowed . "]?/iu", "$1", $_GET['txt_search']); and that works fine for English texts. However, now I need to do the same when the texts entered can be in any language (Russian now, Chinese in the future). How can I clean up the string while preserving "normal texts" in the original language? I though about switching to a blacklist (although I´d rather not...) but at this moment the regex just completely destroys all original input.

    I have created an account type using the AccountAuthenticator stuff as done in the SampleSyncAdapter tutorial. I am now trying to get account preferences working.

  • Filter subform using combobox

    - by TT1611
    This has taken me nearly 2 weeks and I dont know what else to do. I have a main form (UserSearch) that has a subform (TestUserSub). The associated table for both forms is tblusers. very simple; on the main form (UserSearch) I have a comboboxes associated with the fields in the tblusers eg cmbid, cmbname, cmbdept and so on. All I want, is for a user to make a selection from any of these comboboxes and for the associated fields to display in the subform (TestUserSub). I have tried several different versions of code in the afterupdate event in a couple of the comboboxes and nothing is happening in the subform or in other instances I get error message. One example i have tried is filtering running an SQL command Private Sub cmbid_AfterUpdate() Dim strSQL As String If IsNull(Me.cmbaccess) Then Me.RecordSource = "tblusers" Else strSQL = "SELECT tblUsers.[Team Member_ID] FROM tblUsers " & _ "WHERE (((tblUsers.[Team Member_ID])= " & [form_testusersub].[txtid2]))& ";" Me.RecordSource = strSQL End If End Sub The above didnt work..Can someone please help me with this. I have a sample database that i have been working off and by some very strange way, they have managed to do this same thing without calling any code. Is this possible?

  • Visual Studio 2010 - References Dialog Filter

    - by Sphynx
    Visual Studio 2010 adds a new feature to improve loading speed of references in "Add .NET Reference" tab. For example, when the target framework of project is 3.5, it displays only 3.5 assemblies in the list, and says "Filtered to: .NET Framework 3.5". This feature is quite annoying, as it makes impossible to find an older assembly, unless you change a target framework in compilation options. Is there any option to disable that filtering?

  • Performance - User defined query / filter to search data

    - by Cagatay Kalan
    What is the best way to design a system where users can create their own criterias to search data ? By "design" i mean, data storage, data access layer and search structure. We will actually refactor an existing application which is written in C# and ASP .NET and we don't want to change the infrastructure. Our main issue is performance and we use MSSQL and DevExpress to build queries. Some queries run in 4-5 minutes and all the columns included in the queries have indexes. When i check queries, i see that DevExpress builds too many "exists" clauses and i'm not happy with that because i have doubts that some of these queries skip some indexes. What may be the alternatives to DevExpress? NHibernate or Entity Framework? Can we build dynamic criteria system and store these to database in both of them ? And also do we need any alternative storage like a lucene index or OLAP database?

  • Drupal : Custom views filter

    - by Joseph
    Hi, First thing I would say is that I am a Drupal newbie. So, I would appreciate your answer in a detailed step by step process. I am using Drupal 6 and location module. There are two main content types - user profile (using content profile module) and event content type. Both have one field for location. Now, lets suppose in his profile, user is selecting city as Toronto and province as Ontario. And some events have been added for Toronto city. I need one Views, which will display events from user city. So, if user is from Vancouver, and they click on "my city events", they will see list of events from their city. Someone told me that I can achieve this using arguments/ relationships, but I don't know how to do that. Can someone please help me out? I am not good at PHP either :(
