Android :: ExpandableListView - Is Conditional Expansion Possible

Aug 12, 2010

I have an ExpandableListView bound to a SQLite database. To simplify things, lets assume the database contains two columns: title and body. In the ExpandableListView, there is a group for each title, and a childfor each corresponding body.

Now to make things more interesting, some of the rows in the SQLite database do not have a body (that is... they only have a title). As you can see, if there is no body, then there is no reason to expand the group... because the child will be empty (i.e. String body == "").

I'm searching for a way to catch a situation like this, and skip the group's expansion. I don't want a blank child to be expanded. To put it in psuedo code, I want something like this:

Android :: Conditional Restart On Activity OnConfigurationChanged

Mar 19, 2010

I want to make an activity that allows orientation changes on some condition, but not otherwise. More exactly I want to prevent restarting the activity when a background thread is busy.

I have put the configChanges attribute on the activity manifest, and onConfigurationChanged is called when the orientation changes. However I want to allow the app to change the orientation when allowed.

HTC EVO 4G :: Sprint Conditional Call Forwarding

May 25, 2010

Getting my EVO tomorrow, bought from Google I/O attendee. Not 100% sure I am going to ditch my Sprint Touch Pro 2. I think I will activate the EVO using the Google I/O free month of service and use conditional forwarding on my Sprint TP2 subscribed number and direct it to the EVO. That way I can keep the TP2 off, or with the phone radio off at least, and get calls routed to the EVO for free with no/very little delay. That way I can test the EVO without switching service from my TP2, and not give out the temp EVO phone number, and not rack up charges on my existing subscription with Sprint.

To enable conditional call forwarding:
*28 + number + send

To disable conditional call forwarding:
*38 + send

I think this will work without charging me airtime to my TP2 account, as opposed to standard call forwarding (*72) which is quite costly.

HTC Hero :: Conditional Jerky Video Playback

Aug 14, 2009

The bundled sample video (Hero_Sample_Video.mp4) is playing nice and smooth. However, when I try to encode a file in the same format with ffmpeg, I get jerky playback. Videos seem to play slower, then quicker, then slower, etc. I'm encoding with the same settings as the sample clip, i.e. H.264, 480x320 and 48 kHz Stereo AAC audio. I have tried low and high bitrates, different quantizers and even two different containers: MP4 and M4V. I fail to obtain smooth playback even with the H.264 settings from https://help.ubuntu.com/community/AndroidVideoEncoding aimed at Android phones. Smooth video playback is obviously possible on this phone, since the 30 FPS full screen sample clip plays back without a hitch, so what are the secret flags I need to pass ffmpeg to attain this holy grail?

Android :: Static Compilation

Sep 11, 2009

I was working on Freescale iMX31 board, I ported android and it was working fine , but when it came to integration of WiFi & Bluetooth, android forum recommended me to do static compilation for porting over android !

Can I know why some drivers have to be statically compiled before it is ported over android? It was not the case with other drivers which when integrated with android, they worked perfectly well like serial port, usb etc..

Android :: Speed Up Compilation With Mockito

May 2, 2010

In the test project, I am importing the mockito library for standard POJO testing.However, when I import the library, the compilation time skyrockets from 1 second to about 30 seconds in eclipse. The cause seems to be that the whole library is converted each time. So basically, each time a make a modification that I want to test, I have to wait 30 seconds.

Android :: WikiNote - Application Build Compilation Error

Sep 26, 2009

Has anyone got the WikiNote from
http://code.google.com/p/apps-for-android/

What I did was:
1) Checkedout the project via apps-for-android instructions
[svn checkout http://apps-for-android.googlecode.com/svn/trunk/ apps-for-android-read-only]
2) Opened a new Android project using existing source dir [per the WikiNote direction]
3) Cleaned the project and let it rebuild

It won't build the APK though and reports compilation errors (the top level dir is flagged red in eclipse but nothing else is so I can't track down where the error supposedly is)

Android :: Include Information To Droid Application Post Compilation?

May 20, 2010

Currently I supply a user with a URL to click on to download my j2me application. This URL includes their user id as a parameter, a servlet takes this information and dynamically creates a jad file that includes this user id , thus making the user id available to the j2me app.

However, I am now using j2me polish to compile my program and thus have the compiled .apk for this same program. However, I cannot work out how to make this information accessible to the the compiled program as there is no jad / jar mechanism. The information is only available at the time of download.

Any suggestions gratefully received! (is this even possible in an android application?)

Android :: Android Compilation Slow (Using Eclipse)

May 21, 2010

When I change any .java file and build, the compilation takes 16 seconds. I don't understand why it should be so slow. I enabled verbose output for Andoroid.
Window > Preferences > Android > Build output > Verbose.

The result output (Console > Android) is:
[19:46:10] Refreshing resource folders.
[19:46:10] Starting incremental Pre Compiler: Checking resource changes.
[19:46:10] Nothing to pre compile!
[19:46:10] Starting incremental Package build: Checking resource changes.
[19:46:10] ignored resource ...in.classes.dex

[19:46:25] Refreshing resource folders.
[19:46:25] Starting incremental Pre Compiler: Checking resource changes.
[19:46:26] Nothing to pre compile!

The "processing" of .class files took 14 seconds. And it "processed" all files, even from all .jar files linked. I think some thing wrong goes here, as only one .java file was changed. What can I do to improve the compilation speed?

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; ....

Android :: Android / Java - Call Function In Separate *.java File?

Aug 16, 2010

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!
