How To Create Tables That Associate Each Photo With Numerical Value
Apr 9, 2012
I want to create a calculator that has specific functions. So for example if someone wants picture 1,5,7,9 and each photo has a number associated with it, it will deduct from a predefined total number. Once the predefined number is reached, it cannot exceed it. I downloaded Eclipse, ran emulators and have done the hello world. I don't know where to go from here. How to create tables that associate each photo with a numerical value.

Does Android have a "best practices" guideline on creating & populating the db/tables programmatically vs. deploying a .db file in assets?
What are the pros/cons of both approaches?
I have a db with big long strings in several columns, and about 50 rows, so writing the insert statements alone would take quite some space. It seems a waste.

I want to create a photo gallery on Android. I'm using Gallery and BaseAdapter to create a scrollable gallery. Now I want to add action when an image of the gallery is shown(each image's width is the same as screen width), so I need to get its index in the image array. My question is how to get the index of the image which shows on the screen?

How can I create a custom activity that can be chosen by the user via the share option when viewing the photo gallery? I have options like "Share with Facebook, Twitter, FlickR" etc. But I want to add my own option in there.
i.e. Go to "Photos", then click the "Share" button. You will be presented with a bunch of share providers. What do I need to do to get my activity in there?

I'd like to make an Android app that lets a user apply cool effects to photos taken with the camera. There are already a few out there, I know, but I'd like to try my own hand at one.
I have been googling and stack-overflowing, but so far I've mostly found some references to published papers or books. I am ordering this one from Amazon presently - Digital Image Processing: An Algorithmic Introduction using Java
After some reading, I think I have a basic understanding of manipulating the RGB values for all the pixels in the image. My main question is how do I come up with a transformation that produces cool effects?
By cool effects I mean some like those in these iPhone apps:
I already have quite a bit of experience with Java, and I've made my first app for android already. Any ideas?

Is there a way as an end user to associate particular file extensions or mime types with a specific application. For example, I want .djvu to automatically be opened by djvudroid when I click on it in astro. I am on a nexus one by the way.

My activity can be reused in multiple tasks concurrently. It stores a photo associated with the task in a file. If the task is abandoned, how can I know to delete the photo? Currently, I'm planning on keeping a fixed size queue of photos and deleting the eldest photo when the max size is reached.

I am writing an app that needs to be able to open (be associated in the browser download window for example) with a certain file type. The file type has .emx extension and is in an xml format (the top of the files have <?xml version='1.0' encoding="UTF-8"?> ). However, I can't for the life of me get my app associated with this filetype.

I'm a new member; I've had my Fascinate for about 2 weeks.Last night I tried to do something that seems simple: set a song as a ringtone for a specific contact. The procedure is given on page 75 of the manual. But it doesn't work.When I try it, I get a screen that says to press Menu and touch "Get friends" or "Accounts". But pressing Menu does nothing.I've gone through and activated sync for all accounts (and run sync multiple times), and my contacts DO all show up when I select "Contacts" from the home screen, but the manual's procedure still fails as described above.

When I first got the Desire, the inline controls controled the functions of the HTC and Android music players, (not 3cubed for example.) Since installing Doubletwist music player, the controls now control Doubletwist only..? So now if im using the HTC player and press the > controll to pause the song, it starts playing the last song I had open in Doubletwist over the top of the song I was listening to in the HTC app. and the only way to stop it is to use task manager to kill Doubletwist.

I've written an app that can handle the VIEW action for a given mime Type, say "application/foo". By adding the following to Android Manifest.xml the Browser automatically uses my app to open downloads of that type. The G Mail app also tries to use my app to Preview attachments of that type, but it's passing a URI with scheme "g mail-ls://" rather than a "file://" URI. I guess I need to use a Content Provider to get the attachment data, I haven't looked into that yet. But the real mystery is the Email app there just doesn't seem any way to make it open the attachments. Any pointers? Opening attachments is a very common requirement of course, and I would expect the Android platform to encourage developers to write apps to handle more mime types. Instead I couldn't find any answers.

I have a ListView that is populated using an XML file. However, I want each item, when clicked, to start a new Activity related to that item. I understand how to use OnItemClick to start a Toast that shows the selected item's text. However, since the ListView is populated from an XML there is not a specific Id for each item in the list. So, how would I associate an Activity with each item in the ListView when the items do not have Ids?

I have a group on gmail called coworkers. I added many of the employees in my company as contacts. I am now running Launcher Pro as well for what that is worth. I found the option to check coworkers as a group, but I can't figure out how to associate or move the employee contacts under that group. What am I missing? Or am I going about this the wrong way entirely?

I sideloaded a geo-restricted app (Sky Sports Football) because it isn't available in my country (US). As to why that is...I have no clue since it's free. Anyway, I am wondering if there is any way to make the Play Store recognize that the app is installed (bypassing the geo-restriction check) and have it continue to check for updates.
I am hoping this is possible since when I install apps from a TiBu backup, the Play Store has no problem seeing them. TiBu seems to have an option to detach apps from the Market...but I want to do the reverse.

I'm trying to use Android SDK's SQLiteQueryBuilder to join two tables, let's call them t1 and t2, and query that table based on an attribute from each table, say t1.att1 and t2.att2, equaling a certain value. I'm a little confused on the syntax when it comes to the selection.

I need to display a single list, ordered by date which contains different types of data, images, video and whatnot.
I guess you could have one separate table for each type and the use something like FULL OUTER JOIN (simulated as sqlite doesn't support it) and sort on date. But this would be complicated because I still need to have unique IDs across all tables.
Maybe having a master list which has ID and date, and then JOIN in the types tables? But how bad is the performance of this using sqlite? I really like to avoid having a super table which contains columns all the combined types could ever need.

How can I use multiple tables under one content provider? How can I get result from two/three tables ?
Can I provide my own SQL select query from multiple tables in ContentProvider?
Can anybody give me any example or link where I can get idea?

This question has been asked [numerous times] before, but I have not seen any definitive answers, or examples of code that actually works. I would like to associate an Activity with a particular file type. For discussion, assume that I want my Activity to be associated with PDFs. Here is what I currently have. I have experimented with many different values and combinations of values in the intent-filter, but I have yet to get my Activity to start when a PDF is selected.
<activity name="com.mycompany.MyActivity">
<intent-filter>
<action android:name="android.intent.action.VIEW" />
<category android:name="android.intent.category.DEFAULT" />
<category android:name="android.intent.category.BROWSABLE" />
<data android:scheme="file" />
<data android:mimeType="application/pdf" />
<data android:pathPattern="*.pdf" />
<data android:host="*" />
</intent-filter> </activity>

This may be a stupid question, but how do I open a CSV (comma-separated values) file as a spreadsheet on my Evo? Quick Office can open an Excel file (.xls) but not CSV. ES File Explorer can open the file as text but not a spreadsheet.
Also, is there a way to associate particular file types with specific applications?
