Was looking for some guidance here. I need to replace the garbage keyboard bundled with 1.6 for something else. Which in your opinion is the best replacement and why? Maybe some comparisons would help also. Oh, by the way i'm running a mytouch 3g!

If you're like me, you find the new soft keyboard in Android 1.5 difficult to use and slow to type on. The keys are too small, the corrections suck, and the word predictions just aren't that great. It's nothing compared to the slick and intuitive keyboard on the iPhone.
Let's say there was a market app that replaces the keyboard with something much better. I'm talking something with high accuracy corrections and predictions, something that adapts to your typing style as you type, and has a fantastic UI for corrections and predictions. Let's say it increases your average typing speed by a factor of 2x.
Up to how much would you be willing to pay for the app?
I'm talking about something much better even than this, typing software, fast text entry - WordLogic Predictive Keyboard, which costs $24.95.
To use a custom IME, it must be selected from the "Settings app". How does the system do this operation? What are the code files that changes the settings?

I see options in the language and keyboard settings when I connect a physical keyboard, for auto-replace, auto-capitalization, and auto-punctuation.

View 1 Replies View RelatedI've had my Droid since June of 2010 and up until a few days ago the keys have started to stick. Pretty much when I press down on them they stick for a split second and spring back up making a click noise each time I click on certain keys (Almost all of them). Not many of the keys are giving me double letters when I type due to this but some are. I called Verizon about it they want to troubleshoot the issue and I have no problem with doing that, I just will do it later at home since I am out now. So what do you guys think..? Should I replace it or keep using it some more see if the sticking stops? I really REALLY hate to replace my Droid seeing as it's new fresh out of the box and I've had no other problems with it.

View 3 Replies View RelatedI have an app with about 15 threads. Most do mundane tasks and sleep most of their lives. Others collect information and cache it in hashmaps. The hashmaps grow to a moderate size and level out. The number of keys and size of value remains constant, but the contents of the values changes (at 33 keys per second average). When I start my app, I notice the garbage collection interval goes from minutes to once per second, and the amount of garbage is 700k+ each time. In fact as I was writing this, it caused my phone to reboot with an error "Referencetable Overflow". Here's my question: Are there any tricks to identifying which threads are producing the garbage, or even finding out more about what garbage they are producing?

I didn't use much Java before Android so my knowledge concerning the gc is marginal. Now I'm developing a highly physics-based game and therefore I need to do many calculations each time step and many (25) time steps per second. At the moment I'm almost only using local objects (float) in my methods, so I guess they are allocated every time the method is called (which might be, for example, 25*100 = 2500 times a second , for 100 objects with calculations on them). This causes massive activity of the garbage collector like freeing ~10000 objects every 1-2 seconds (taking ~200ms on a real device). Now I really want to optimize that because even there's no noticeable delay due to the GC (and the frame rate is constant), this seems just not well. But I read on many documentations concerning Java optimization, that there is not much to optimize in modern versions of (desktop) Java, because the GC is fast enough. Does this apply to Android, too? Does the compiler optimize anything like frequently, steady allocated objects (like floats)? What would be best practice: keep all local objects and allocate and free them all the time or use class-global objects, even if they are only used inside one particular method (which is bad programming style but conserves GC?

But the VM's garbage collection hinders my program's performance.
I checked my program's execution time for each in OnPrevFrame(byte[], Camera)

I copied parts of logs below. (local time is just before and after of signal processing, and global time is time stamps for every onPreviewFrame() calling )Also I executed onPreviewFrame without any signal processing on it, but
the garbage collection is also carried showing debugging message around 60ms it spends for memory release.

I'm drawing a rect to a surfaceview. Nothing special, just a test like this, in the surfaceview-extended class:
private int mPosX = 0; private Paint mPaint = new Paint(); Code...
the rect just bounces around the screen. I'm watching DDMS, I still see the garbage collector being called, even with this simple draw loop. There is no other application code being executed.
I'm wondering if it's realistic to expect the gc to not be called at all if we take care to not allocate any objects during our draw loops. I'm trying to extend this example to do some smooth animations, but every once in awhile the gc is called and you can see the drawing stutter. Although none of my application code is allocating any new objects, I don't know what the underlying API is doing inside surfaceview etc, and I doubt we can control that. Just wondering if this is not possible, I'd prefer to abandon this game idea up-front if we can't guarantee smooth animation.
I am developing a camera application , where the frame rate is important. However, camera uses a preview callback function which allocates a byte[] array of 230400 bytes, which makes it necessary for the garbage collection to step in. Can someone suggest me a way to avoid garbage collection stepping in?
View 10 Replies View RelatedHi, I have discovered while using DDMS that the basic OpenGL system calls in my code are allocating memory and causing the garbage collector to fire! It's not the system calls themselves causing the problem but the use of direct byte buffers to pass data in.
The direct byte buffers I use in calls such as glVertexPointer & glTexCoordPointer lead to java.nio calls to read the byte buffers, leading to objects of type org.apache.harmony.luni.platform.PlatformAddress being created.
These buffers are the same as in the example OpenGL code. I am creating a ByteBuffer using allocateDirect() and then creating an IntBuffer using ByteBuffer.asIntBuffer() to pass data to the OpenGL functions. The problem occurs as the system is reading the buffers.
Is there a way around this? Maybe using something other than direct byte buffers? It seems that using this method, OpenGL code of any complexity (ie a lot of OpenGL system calls in every frame) is doomed to pause a lot. I am aware that these calls should be kept to a minimum, but I still need to use a certain amount of them.
I know this may be a dumb question, but my background is more in c++ and managing my own memory.
I am currently cutting down every single allocation that I can from one of my games to try and reduce the frequency of garbage collection and perceived "lag", so for every variable that I create that is an Object (String for example) I am making sure that I create it before hand in my constructor and not create temporary variables in simple 10 line functions... (I hope that makes sense)
Anyways I was working though it some more tonight and I realized that I a may be completely wrong about my assumption on garbage collection and primitive types (int, boolean, float) are these primitive type variables that I create in a 10 line function that gets called 20 times a second adding to my problem of garbage collection?
I'm performance tuning interactive games in Java for the Android platform. Once in a while there is a hiccup in drawing and interaction for garbage collection. Usually it's less than one tenth of a second, but sometimes it can be as large as 200ms on very slow devices. I am using the ddms profiler (part of the Android SDK) to search out where my memory allocations come from and excise them from my inner drawing and logic loops. The worst offender had been short loops done like,
for(GameObject gob : interactiveObjects)
gob.onDraw(canvas);........................
I have screen 1 of my app which I want to transition smoothly into screen 2.
I want the transition to be smooth but I don't mind a slight pause before or after the transition. Before the transition I dump a lot of objects that are no longer needed from screen 1.
However, as luck would have it (!), the garbage collection almost always takes place during the transition causing the frame rate to drop and the transition looks terrible :(
Is there a way for me to either force the garbage collection to complete before the transition or delay until after the transition is finished? I have tried System.gc() in various places but it doesn't seem to help performance.
I have a tight game loop in a separate thread where I paint a lot of things on the canvas.
When I paint the score to the canvas I use the following function code...
When I check allocations in ddms I see that .toString not totally unsurprising allocates a char array on each conversion from an Integer to a String. This array will eventually be claimed by the garbage collect and cause uneven rendering of frames on slow android devices.
Is there a better way of painting integers on a canvas that won't cause new allocations and garbage collects?

The offending code is here, which formats a price for each item in the list: String price = cursor.getString(columnIndex); final float pricef = Float.parseFloat(price); price = new StringBuffer("$").append(String.format("%. 2f",pricef)).toString(); ((TextView)view).setText(price);
If I comment out the line with String.format, the garbage collection goes away. So what's the "right" way to do this to avoid allocations? That database field holds an unformatted text string which I'm trying to format into proper currency format (example: format "1.5" to "$1.50")

Dev = ne0fhyk from XDA.
From the XDA forum: Link to app page = [APP][ROOT/Keyboard] Keyboard Manager - Dual keyboard: Portrait/landscape switch - xda-developers
Verbage:
Keyboard Manager allows you to customize what keyboard (input method) appear on input based on your phone orientation.
It displays the keyboards you have enabled on your android device, and let you select one per orientation (landscape/portrait).
As your phone switch orientation, the app automatically switch the keyboard.
Requirements:
- Rooted android device (app was tested on Samsung captivate 2.1)
- Root Explorer app, or similar app that allows you to edit the permissions of a file.
To install:
1- Download the app (KeyboardManager.apk) on your device sdcard.
2- Using Root Explorer, move the apk file to /system/app
3- Using Root Explorer, edit the file permissions like below:
-- User: 'Read/Write' checked
--Group: 'Read' checked
--Others: 'Read' checked
4- Exit Root Explorer
The app should be visible in your launcher as 'Keyboard Manager'
Update:
- Added option to disable notification icon
-' start on boot' feature is disabled because it's not yet complete and tested... Sorry for the confusion
Bugs:
-On certain applications (i.e: Messaging on Samsung Captivate), the input window occasionally freeze on orientation switch. Exiting the app, and resuming should fix it.
The app is still in development.
I would like to play around with some ideas and develop a soft keyboard for Android to replace the default one.
Is there any general information about soft keyboard development for Android out there?
Any best practices or guidelines?
Can I do with my keyboard application pretty much anything I could do with a normal Android application?
Can I do HTTP connections to synchronize keyboard data with a cloud DB and other phones I have?
Can I open other windows/screens from a key press, e.g. to display a custom input interface different to a normal QWERTY one. If that doesn't work, can I use a pop-up dialog instead?
