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..

Mar 30, 2010

i want to display a msg to the user (msg box or Toast) when exception happend in a static SQLite Database class that i use. the problem is that i cant call a non static method in a static class , how can i handle this. this is the class

private static SQLiteDatabase getDatabase(Context aContext) {

Android :: Cannot Make Static Reference To Anon-static Method

Feb 7, 2010

I'm having some issues with the old "Cannot make a static reference to a non-static method" error in my Android program. I am creating a sand falling game (similar to the Powder Game) and I created a class called Control to create a Control Bar at the bottom of the screen with a slider for brush size (that works fine) and a button to pop up a Dialog to allow users to pick the selected element. However, when I call DemoActivity.showDialog(2) from my code, it gives the static reference to non-static error (DemoActivity is the main activity of my application). I also tried changing it to just Activity.showDialog(2), but I got exactly the same error!

Here's my code:

CODE:................

I fixed it by adding the following to my Control.java code:

CODE:..........

And then calling control.setActivity(this); from my onResume section of DemoActivity.java!

Replace Single Row View In Custom STATIC ListView - STATIC Data

Mar 18, 2013

I have Eclipse Juno and I'm working on an app with that.

The main activity will have a scrollable menu that takes you to all the other activities.

So the general structure/outline right now:[HIGH]Relative Layout ImageView (header logo type thing) ListView (the actual scrollable menu)[/HIGH]Here's the problem though... I can't find any simple list tutorials. I can easily make a single line list work but I need to make a two line list and one that is static, not dynamic and no examples are out there for that. It's like if you want to make a 2 line list, you can only learn how to do it in the most code-heavy ridiculous way possible.

Essentially what I am looking for with the list is this: Item one: Centred, bold, non selectable title (Resources)

- Item two-??: two line list items, click-able to a new activity, title of the section on first line, description on the second line.

- Item ??: Centred, bold, non selectable title (Tools)

- Item ??-??: two line list items, click-able to a new activity, title of the section on first line, description on the second line.

Nothing dynamic that is ever going to change, no super complex wonkey calculations, just to simply have the data set in stone (preferably via XML) and to call it into the list.

I experimented with some of the other list views and no matter what I did, I could get, via editing the resources and NOT using Java, more that one item on a single line but it wouldn't format it properly according to the layout I guess because I haven't got the ID correct or whatever I don't know.

I mean, all the examples I've seen for a 2 line list are extraordinarily over-coded and just bloated. I mean I have a website I am still working on in C#/ASP.net that has far more complex things in it with half the code that I've seen for the examples of the two line lists.

I tried on my own to figure it out (I am decent with C# and vaguely familiar with Java, self taught, and programming for some other systems like Python, again all self-taught), but like ALL coding references, they're organised by the actual code you implement (that you don't know) instead of by what you want it to do (so you have to search the whole code base to find something that you don't know what it's called but know what it does). >:C

Android :: Static Vs Non-static Inner Classes

Mar 9, 2009

I have been finding it convenient to extend Handler in many of my activities to handle messages specific to the activity. The handler sublass is an inner class of the activity and needs to access its state. I am wondering if there is any performance difference between making the handler subclass static and passing in the activity explicitly in its constructor or making the subclass an "instance class" and letting the vm worry about my accessing members of the containing activity.

The static approach:

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

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?

Android :: Is The Static Safe ?

Jul 29, 2009

I use a single static class in my code that defines a static field which I'm reusing between Activity onStop/onStart invocations. Here's a scenario:

User clicks on "Authorize" button (static data is initialized) Activity is stopped and web browser is called
Browser executes callback and Activity is restored (static data is reused)

At least one of my users reports the failure at step 3 which I cannot reproduce but which looks like reset of static data.

Android :: App Static Storage ?

Sep 30, 2010

I am creating an Android application which will have some embedded music inside of it ( ~ 80 MB ). I was planning on putting it in the res/raw folder.

Since android stores that all in it's internal memory, is this way too large? What are my options? I have come up with the following:

Copy resources out of internal storage and onto the SD card when application first starts. Afterwards remove from internal storage (is this possible?)
Download music from the web when the application first starts.

I would really prefer not to have to go with option 2 since I want the app to be entirely offline and the static music is not going to change (except between releases).

Android :: Mic Audio Capture Too Static

Jun 3, 2009

As a first step toward a speech recognition project, we wrote a simple voice recording application based on the information in this thread:
http://groups.google.com/group/android-developers/browse_thread/threa...

It is working; however, the audio is extremely poor too static for our needs. As a comparison, we did a similar audio file captured with audacity on a PC and it was much better. Has anyone been able to record high quality audio with the android dev phone? According to the documentation of MediaRecorder, there is only one audio encoder "AMR (Narrowband) audio codec" and three output formats--3gpp, mpeg, and raw AMR:
http://developer.android.com/reference/android/media/MediaRecorder.html

According to wikipedia, AMR encoding is only 8hz. Is there a better option available perhaps a lower-level API compared to MediaRecorder? We are testing on Windows XP, with a Logitec USB microphone, eclipse ganymede, and we are using all the defaults for an android 1.5 app (no emulator command-line options. We defined the SD card in AVD manager).

Android :: Static Variable Instantiation

Apr 1, 2009

I have noticed in my application(s) that after a call to Activity.finish() that the static variables that I declared in my classes still hold the values that they were changed to during the activity's life cycle. Upon the re-launch of the activity, the program does not re-instantiate the variables as declared or set them to the default java behavior. Is there something that I can do to cause this to happen, other than re-setting every static variable in my application?

Android :: Use Of Static Finals In Activity

Sep 8, 2010

Why is the use of static final variables encouraged to declare constants over just final variables? The use of static sounds logical when there will be many instances of a class but is this argument correct when used for a Android activity. In fact, since the Class instance will be around even after the activity finishes and is eventually garbage collected, it seems like all these constants will still be in memory until the class loader is around. Also, does the compiler inline non-static final variables(ints and String) just like it does for static final variables?
