  • Android 1.6: onActivityResult is not called

    - by Seb
    Hi, I have a problem with the method "onActivityResult". I create a new Activity from my main activity: Intent intent = new Intent(this, NewActivity.class); startActivityForResult(intent, 0); The new Activity is ended like this: Intent resultIntent = new Intent(); resultIntent.putExtra("vid", hmvenues.get(venues[currentPosition])); resultIntent.putExtra("name", venues[currentPosition]); setResult(RESULT_OK, resultIntent); finish(); But the Method onActivityResult seem to be not called @Override public void onActivityResult(int requestCode, int resultCode, Intent data) { Log.d(this.getClass().getName(),"onActivityResult"); ... } Does anyone have an idea, what I did wrong? Thanks!! Seb

  • Android - Where to store generated bitmaps?

    - by Josh
    I've got an app which dynamically generates anywhere from 6 to 100 small bitmaps for the user to move around the screen in a given session. I currently generate them in onCreate and store them to the sd card, so that after an orientation change I can grab them out of external storage and display them again. However, this takes time (the loading) and I'd like to keep the bitmap references around between lifecyle changes for quicker access. My question is, is there a better place to store my generated bitmaps? I was thinking about creating a static storage library in my base activity, something that would only need to be reloaded when the app is completely removed from memory (shutdown, other apps need resources, 30 minute restart, etc). Ideally, I'd like the user to be able to back out to the title screen, click a "Resume" button, and in onCreate I just have access to those resident bitmap references instead of having to load them from storage again. For this reason I don't think Activity.onRetainNonConfigurationInstance is what I need. Alternatively, is there a better way to handle multiple generated bitmaps than what I'm doing or the plan I described?

  • android Convert phone number in International Format

    - by Arutha
    I'd like to know whether it's possible to have phone numbers converted into international format when a call is outgoing. For instance, if a french user (sorry it's the only format i know i won't make a mistake :-) try to call with the national format : 01.47.12.34.56 then a method will convert it into international format like this : +33.1.47.12.34.56 I've looked into the doc of the PhoneNumberUtils but i don't know if there is a method doing what i want.

  • What is the component a popup menu click originated from

    - by Ralph Rickenbach
    Having a popup menu attached to several components on a form (buttons, but also things like TCharts), I would like to know which component was right clicked to start the popup menu in the first place. The Sender parameter of the click method just points to the TMenuItem, its parent to the popup menu (or the parenting menu item). How do I get the originating component?

  • How Android BaseAdapter notifyDataSetChanged works?

    - by Yama moto
    In the document for the method notifyDataSetChanged of class BaseAdapter noted that "Notifies the attached observers that the underlying data has been changed and any View reflecting the data set should refresh itself. " Supposed I changed the 3rd element in my string array (array data for the listview), what "any View reflecting the data set should refresh itself" means ? Does the 3rd view item in my list view be notified ? Also, how is notifyDataSetChanged() and getView() concerned ? Thanks in advance

  • Android: How do you delete a folder starts with period

    - by jclova
    I am trying to delete a folder in sdcard. I can delete normal directories, but a directory that starts with period cannot be deleted. (ex. ".helloDir") if (dir.isDirectory()) { String[] children = dir.list(); for (int i = 0; i < children.length; i++) { new File(dir, children[i]).delete(); } } children is null if dir starts with period (ex. ".helloDir").

  • Can FLV AAC stream be played in Android

    - by HariKJ
    Hi, I'm trying to build a radio player and the client is providing a stream which is a FLV container with the audio being AAC When I read the headers it shows up as audio/aacp. I have tried all possible ways such as using the 1) Streaming through mediaplayer (Does not work) 2) Use the NPR mode of using a proxy stream (I get a broken pipe exception) 3) Play it in chunks ( Plays but I need the SDCard and the playback is not very great) 4) Use the GPL'd FAAD2 Library but I would have to pay the royalty fee Can some one help me out on figuring this issue out. The last option that I have is to have my client change the stream to mp3 container (which I know that it works) Regards, Hari

  • Radio Button selection Changes Toast on Android

    - by Bub
    I was writing a simple test application. There are two radio buttons within the app. There id's are "radio_red" and "radio_blue". I wanted to create an onClickListener event that read the text associated to the button and then returned a basic "Right" or "Wrong" toast. Here is a sample of the code: private OnClickListener radio_listener = new OnClickListener() { public void onClick(View v){ RadioButton rb = (RadioButton) v; String ans = rb.getText().toString(); String an1 = ""; if (ans.trim() == "Yes") { ans = "That's Right."; } else if (ans.trim() == "No") { ans = "thats wrong."; } else { ans = "none."; } Toast.makeText(v.getContext(), ans , Toast.LENGTH_SHORT).show(); } So far no joy. Here is my code snippet. I've checked my "main.xml" and the text associated to the buttons are referneced correctly. I added trim to make sure of that. However, all that is ever returned in the toast is "none." What am I missing? Thanks in advance for any help.

  • Android quotes within an sql query string

    - by miannelle
    I want to perform a query like the following: uvalue = EditText( some user value ); p_query = "select * from mytable where name_field = '" + uvalue + "'" ; mDb.rawQuery( p_query, null ); if the user enters a single quote in their input it crashes. If you change it to: p_query = "select * from mytable where name_field = \"" + uvalue + "\"" ; it crashes if the user enters a double quote in their input. and of course they could always enter both single and double quotes.

  • two android threads and not synchronized data

    - by Sponge
    i have a (perhaps stupid) question: im using 2 threads, one is writing floats and one is reading this floats permanently. my question is, what could happen worse when i dont synchronize them? it would be no problem if some of the values would not be correct because they switch just a little every write operation. im running the application this way at the moment and dont have any problems so i want to know what could happen worse? a read/write conflict would cause a number like 12345 which is written to 54321 and red at the same time appear for example as 54345 ? or could happen something worse? (i dont want to use synchronization to keep the code as fast as possible)

  • Android: Issue with acceptable file types via bluetooth

    - by poeschlorn
    Hi guys, i've got a problem with pushing files to my nexus one: It seems to me that there is only a small selection of file types that are accepted by my phone (such like jpg, gif and so on). I recently tried to push other files to my phone (in my case gpx) and my phone has rejected it automatically... is there a way to bypass or extent this filter? Is there also a way to catch those files by a service? greets, poeschlorn

  • Aligning Android Button To Bottom in RelativeLayout??

    - by MobiKnow
    I'm trying to align a button to the bottom right and bottom left of my screen, using a RelativeLayout. I want to do this to keep the same relative layout across different screen sizes. Currently the buttons on my screen move up/down depending on the resolution of the screen. 320x480 puts the buttons higher on the screen versus 480x800. I'm trying to get my screens to look the same between the two sizes. Any information you can provide is greatly appreciated. Thanks, MobiKnow.

  • Android Assets No Value Read?

    - by BahaiResearch.com
    AssetManager assets = myContext.getAssets(); String[] files = assets.list("MyFolder"); InputStream myInput = assets.open("MyFolder/" + files[0]); int i = myInput.read(); in this case 'i' is -1 meaning nothing read. Why would nothing be there if the file is there, the variable 'files' has the file as well. Do I need to do anything to the file I put into the Assets folder in get it to be readable?
