Android : Can I Write An App In Java And Convert It Later?
Apr 12, 2010
I've got a lot of experience in Java but none developing mobile apps. I'd like to write an application using Java/Swing and then convert it for use on an Android phone. Is this feasible or do I really need to develop from the ground up for the Android platform? I don't own an Android phone as I can't afford one at the moment, and the Android emulator is so slow that I find myself wasting a lot of time sitting around waiting.

I created an app in app inventor and it works, but to understand what I have created I want to do code instead...I have there pages.
1. Page one front cover enter app
2. A control page
3. a settings page.
The settings page is what I am working on now, and I have links to all of the three pages.The settings page in here is a list of values, some we add to and can select on another page, others we select from a fixed list based on the items in a list.eg. I have and English list and a Russian list and Danish list. Each list contains 5 pre determined hardcoded values Value1,2 3 4 and 5, these values are populated from the selected list and saved and then can be used elsewhere.
In app inventor, I use a listpicker to select from the list of 3 languages, the index is used to report the 5 corresponding values English, Danish and Russian are items in language_array..The values arent anywhere as yet as dont know where to put them.
In app inventor I have the languages Tag for each language and on for each value.When I select the langiage with the list picker, it gets the values from the stored tags and displays them in a text field for each value.
English -------> Value 1 English
Value 2 English
Value 3 English
Value 4 English
Value 5 English
Russian -------> Value 1 Russian
Value 2 Russian
Value 3 Russian
Value 4 Russian
Value 5 Russian
Danish -------> Value 1 Danish
Value 2 Danish
Value 3 Danish
Value 4 Danish
Value 5 Danish
these values are stored in tinyDB with a tag.I then recall stored tag Value 1 into a command.for now I would be happy if I can create the list in eclipse and recall these value, storing them on and recalling them will come later.I have tried spinner, alert dialog but keep getting various errors.

I am trying to get a FileInputStream object on an image that the user selects from the picture gallery.
This is the android URI returned by android.provider.MediaStore.Images.Media.INTERNAL_CONTENT_URI content://media/external/images/media/3
When I try to construct a java URI object from this object, I get an IllegalArgumentException with the exception description Expected file scheme in URI: content://media/external/images/media/3 whereas the android URI shows the scheme as content
Never found a solution for the original question. But if you want the byte stream of an image in the pictures gallery, this piece of code will do that.

I'm having some problems porting a Java application to work in Android platform. I detected an incompatibility problem between java sun and Adroid sdk in java.lang.Class. I oberved that: public Field[] getFields() Returns an array containing Field objects describing all fields which are defined. That's array is sorted as attributes are declared in the main Class in sun jdk. For example, next Class is defined as: public class Example { public boolean stop; public int atr1; public String name; ....

I do an import of the full package name / java file, and if I do a <classname>.<method>, SOMETIMES I can get it to access - other times I get a lot of can't use a static in a non static bunch of talk. I'll admit I'm new to Java, so what do I need to do? Call a class instance first, then call my methods? I'm rather confused by this, as I want to put all of my 'functions' into a FunctionsList.java file, and all of my main Activity (UI) into a MyActivity.java file.
For example:
<MyActivity.java>
import com.example.FunctionsList;
private class MyActivity extends Activity {
FunctionsList.function();
}
9/10 times I get that static/non-static error. If I put all of my functions into MyActivity.java, I have zero problems!

I was going through the code for Activity.java and ApplicationContext.
Both these classes define many functions of Context Interface. Take for example startActivity.java
Activity Class has its own implementation of startActivity ApplicationContext class also has an implemenetaion of startActivity.
Now there are 2 observations...
CODE:..........
Questions: 1. Who uses ApplicationContext class? 2. Does Activity class ever deal with ApplicationContext class (as given in the javadoc comments of ApplicationContext.java).

Has anyone tried the app VLC Stream and Convert? VLC Stream & Convert v0.4.28 Application for Android | Multimedia. It looks promising as a streaming option but I can't work out how to set it to actually stream videos to the phone. It's working as a remote (so VLC is working correctly) but there are no instruction available on how to configure streaming.

Can anyone tell me how to convert my M4a files into MP3? I am using an IMAC which is becoming a major problem in syncing with my Droid X. Additionally, I am using DoubleTwist and am finding several bugs. Does anyone recommend a different music player? B Tunes? I need to convert the files into mp3 as it appears that Droid X only can read mp3 files and can not read AAC files.

I'm getting an illegal argument exception when trying to convert a coordinate in degrees:minutes :seconds .decimal format with the minute value is 59 and the seconds is greater than 0. I think the function compares seconds and they must be less than 59, where they should be less than 60. Here is the error with the coordinate: 05-13 22:27:57.071: ERROR/AndroidRuntime(3924): Caused by: java.lang.IllegalArgumentException: coordinate=30:26:59.5644 05-13 22:27:57.071: ERROR/AndroidRuntime(3924): at android.location .Location. convert (Location. java:249)

I need to convert from XML to Wbxml for Client-Server Communication using AirSynC (Microsoft Exchange Active Sync Protocol). I found XML to WBXML parsers available in ../dalvik/libcore/xml/src/ main/java/org/kxml2 but there was no official documentation regarding these apis. Inbuilt Google IM Application available in ../packages/apps/IM makes use of separate XML<-->WBXML parsers instead of using existing org.kxml2 package listed above and makes use of Native call for SynCML Tag Table mapping.

In anticipation of a new HTC Incredible soon, I opened a gmail account. I have exported 12 years of calendar, thousands of contacts, notes, and tasks from a PC palm desktop. It created a .dba file, which gmail does not recognize. How can i convert it to .csv or whatever? I was able to easily import ~1000 contacts from my Mac address book.
