  • SQLite in android

    - by klaus-vlad
    Hi, My android application uses an sqlite database and during first run it deletes some rows . The next time it runs it tries to do the same , but because the rows were previously deleted it fails . I use SQLite database browser to inspect the database ,after first run (when the rows are deleted) and I observe that the rows that no longer should exist are still in the database , even if ehwn running the app again those rows are no longer visible ! What is the cause for this behavior ?

  • Android adding external libraries to project

    - by wuntee
    I have a project that I would like to add external libraries to (and have them packaged with the application) but I am not sure it is happening. I read on this link: http://developer.android.com/intl/fr/guide/appendix/faq/commontasks.html how to, but they do not show up in any of the /data/data/project directories. Does anyone know how I can confirm that the libraries were in fact added to the project for use at runtime? Thanks.

  • Creating an empty Drawable in Android

    - by Kai
    Creating a Drawable that is completely empty seems like a common need, as a place holder, initial state, etc., but there doesn't seem to be a good way to do this... at least in XML. Several places refer to the system resource @android:drawable/empty but as far as I can tell (i.e., it's not in the reference docs, and aapt chokes saying that it can't find the resource) this doesn't exist. Is there a general way of referencing an empty Drawable, or do you end up creating a fake empty PNG for each project?

  • Android MapView: Disable auto zoom

    - by Ola Andersson
    Hi. I have made an Android app that shows a MapView with two overlays, one MyLocationOverlay and one custom overlay. I am programmatically zooming and panning to what I want the map to show. It also auto pans to my current location. The auto pan is moving the map away from what I want to show. So my question is simply: How can I disable the auto pan? Thanks, Ola

  • An EventBus framework for Android

    - by Benju
    Can anybody recommend a good framework for handling events in Android? These would be business logic events like UserUpdatedEvent. I am looking for something similar to the EventBus provided by GWT-EVENT but for a JVM that supports weak-references.

  • Redundant margins when adding ImageView to ScrollView in Android.

    - by Shmuel Meymann
    Hi.. I have been trying to use a ScrollView on a single ImageView with a JPG (~770 x 1024) over an AVD that's 600x800. My main.xml is: <?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" > <ScrollView android:id="@+id/scroller" android:layout_width="fill_parent" android:layout_height="wrap_content" /> </LinearLayout> Now, I add a single ImageView with setContentView(R.layout.main); ScrollView sv = (ScrollView)findViewById( R.id.scroller ); ImageView iv = new ImageView(this); iv.setImageDrawable( new BitmapDrawable( "/sdcard/770x1024.jpg" ) ); // same happens with ScaleDrawable. iv.setScaleType( ScaleType.CENTER_INSIDE ); sv.addView( sv ); // and it does not go any better if I use Linear Layout between the ScrollView and the ImageView. The result is The image was displayed in a middle of a ScrollView, wrapped with background area on top and bottom as following: ##### ##### image . . . ##### ##### Where ##### stands for background area I tried to set the background of the ImageView red, and it verified that the blank margins were ImageView background. iv.setBackgroundColor( color.Red ); Where I would expect the image to take no more than its size (scaled to the AVD size) and I expect the ScrollView to let me scroll over the remainder (if any). For some reason, I see that the drawable size is 600x1024. Moreover I tried to add a LinearLayout with a dummy text view such as the linear layout is a parent to the ImageView and the TextView, and the ScrollView is a parent to the LinearLayout. LinearLayout dummy = new LinearLayout( this ); dummy.addView(iv); TextView someTextView = new TextView( this ); someTextView.setLayoutParams(new LayoutParams( LayoutParams.FILL_PARENT, LayoutParams.WRAP_CONTENT )); dummy.addView( someTextView ); sv.addView( dummy ); The result was very peculiar: The entire layout was set into the width of a text-less text view (19). It is important for me to avoid stretching the image. What is the recommended way to implement a display of a page that can be potentially scrolled? Do I have to do it manually with a plain layout and scrolling upon OnMove events? Thanks Shmuel

  • Packaging Android resource files within a distributable Jar file

    - by Jeff Gilfelt
    I am working on some reusable Android code that I would like to distribute to other developers for use within their own applications. The code has some resource dependencies (layouts, xml & png drawables) that I would like to be able to include and reference within a single package (Jar file). Is this possible, and if so what is the best method to do this?

  • Playing an arbitrary tone with Android.

    - by fiXedd
    Is there any way to make Android emit a sound of arbitrary frequency (meaning, I don't want to have pre-recorded sound files)? I've looked around and ToneGenerator was the only thing I was able to find that was even close, but it seems to only be capable of outputting the standard DTMF tones. Any ideas?
