Android : Maximum Size That VM Allocate For Loading A Image With BitmapFactory?
Mar 1, 2010
Some of you may met the same problem, I was using BitmapFactory.decodeStream, and got this exception: Code...
I know the reason is because the BitmapFactory is trying to decode an uncompressed version of a big image(in my situation, jpg). I can use BitmapFactory.Options.inSampleSize to fix it. but my question is what's the maximum size that VM would like to allocate for loading a image with BitmapFactory? so I can do some scale before it loads.

I have an activity which uses android:theme="@android:style/Theme.Dialog". The activity contains an ImageView which can show images of different dimensions. The ImageView should scale the Image so that it entirely fits into the window, at least on axes fits entirely and maintains the original aspect ratio. The size of the dialog should only be as large as the ImageView (plus its border width).
I tried the following but the dialog window always uses the whole available space:

I have the following code which I tried to build a Bitmap from an input stream and I want my output bitmap to be 20 x 20:
BitmapFactory.Options opts = new BitmapFactory.Options(); opts.outHeight = 20; opts.outWidth = 20;
InputStream stream = // an input stream to my image Bitmap bm = BitmapFactory.decodeStream(stream, null, opts);
But when I tried it, I do get a bitmap from the inputstream, but it does not scale it to 20x20 which I specified in the BitmapFactory.Options.

I learned from several discussions of this group that BitmapFactory.decodeFile() allocates heap memory outside of the "java heap". My app receives encrypted files from a remote server. Decoding those files needs a lot of heap space. After finishing this decoding step most of the allocated heap space will be freed by the GC. But the (total) heap size - as displayed by the DDM - remains large. In this situation there is not enough heap space outside of the "Java heap" to decode even medium sized image files using BitmapFactory.decodeFile(). At the moment I limit the size of encrypted files to ensure that the Java heap space never increases to more than 10 MB. This ensures that there is enough memory for BitmapFactory.decodeFile(). But this is not very elegant.
Is it possible to tell the dalvik-vm to reduce the (total) heap size to have more space for decoding images or is there another solution?

I use http://stackoverflow.com/questions/541966/android-how-do-i-do-a-lazy-load-of-images-in-listview/3068012#3068012 to load images in a ListView and a GridView. It works but the images are loaded form bpttom to top. How to fix that?
Bonus Question: Can I use a loading animation in a image view while the real image is loaded? Right now it's just a default image.

basically what i'm attempting to do is place several images into 1 zip file, and then read the images back out of the zip file, and draw them onto a canvas using BitmapFactory. This is what my code looks like, but when i debug i only get a source not found error.
Code: try {..............

I can't wait to try out the new 1.6 goodies, but first I'm retargeting my existing applications, and I decided to start with Daisy Garden. Changing to android:targetSdkVersion="4" caused the application to segfault on startup and discovered that the BitmapFactory.decodeResource method now performs scaling based on screen density. In this case the behaviour is unwanted - I'm loading a set of masks that are scaled later during composition. So I've quickly inserted the following method, which seems to perfectly mimic the previous behaviour:
private Bitmap loadBitmap(int resId) { BitmapFactory.Options options = new BitmapFactory.Options(); options.inTargetDensity = 1; options.inDensity = 1; return BitmapFactory.decodeResource(context.getResources(), resId, options);
}

Our Android app does a lot of image decoding. We fetch a lot of images from the internet, local storage caches, etc. Up to now, these images are being decoded on the UI thread (using BitmapFactory.decodeX() methods). It's been causing some timeout crashes because the UI doesn't respond quickly enough to user input.
I could write a little AsyncTask that encapsulates decoding, but I'm not sure that's a good idea. Spawning threads is expensive, and that would be spawning and tearing down a ton of them. So what's the best way to put this on another thread? Do I need to go to the extent of writing a Service? That seems a little heavy-weight. Are there any solutions for this already out there?

I have an ImageView which I want to always be the same size. If the image is smaller than the view, I'd like it to be centred in the view. If the Image is larger than the view then I'd like it scaled down - with aspect ratio preserved.I've had several attempts at this myself

I want to display a fancy 'loading' image at my app's startup time.
The problem: my startup code is mostly GUI related, hence needs to run on UI thread.
Is there a way to do both - that is run UI-related code on UI thread while an image is displayed to the user?

Saving the file code...
The last line gives a null pointer exception, why is BitmapFactory.decodeFile returning null? I can verify that the file is getting saved correctly as I can pull it using adb and see the png displaying properly.

Currently I'm implementing a REST client which shall parse the XML response messages. It is intended, later, to be running on an Android device. Thus, memory and processing speed is quite an issue. However there will be only one XML response at a time so processing or holding multiple XML documents at a time is not an issue.
As fas as I understood there are three ways of parsing XML with the Android SDK:
SAX
XmlPullParser
DOM
Reading about these different parsing methods I got that SAX is recommended for large XML files as it won't hold the complete tree in memory like DOM.
However, I'm asking myself what is large in terms of kilobytes, megabytes, ...? Is there a practical size up to which it does not really matter whether using SAX or DOM?

I am going to install first application in my android phone, but having some doubts
related to Android Memory (Maximum size of APK).
Help me know and solve the problems:
What is maximum size of the apk that can be supported by the android ?
When we install any apk file in real phone, where does application installed (in SD-card or other memory) ??
I have referred this link: http://groups.google.com/group/android-developers/browse_thread/thread/7965885da4d1a03a and also searched lot.
I came Across the search on the web that many people are facing the same issue What is the maximum size of Application supported by Android. I think this question also help to the people who are connected with Android application programming and development.
Update:
This time i am having 58Mb application from that 52.5MB Images and it runs on the my HTC Hero mobile but On Emulator, it shows an error:
Failed to upload my_application.apk on device 'emulator-5554'
java.io.IOException: Unable to upload file: No space left on device
Launch canceled!
Way to store images inside the Drawable folder? is there any way to zip the images or such method?

I have an app which does a bunch of image manipulations, and those images are ideally full-screen sized. It works on a G1 (or HVGA emulator), but runs out of memory on a WVGA emulator instance, because full-screen images use twice as many pixels. Fine, I can work around it by manipulating smaller images, then scaling up to WVGA at the end. There's some loss of image quality, but this is unavoidable on a WVGA device with a 16MB heap limit, so I'll live with that.
When a real WVGA device hits the streets in the next couple of months, though, it's likely to have more than 16MB heap per app, for just this kind of reason. So for best image quality, I'd like my app to adapt to this situation, and use full-screen-sized images on such a device. IOW, I'd like to implement a heuristic which sets the image size based on heap size.
In order to do so, however, the app needs to know what the maximum heap size is, and I haven't yet found an SDK call which will return this information. The various Debug.get* memory calls all seem to be to do with how much heap you have *allocated*, not how much you theoretically *can* allocate. I understand that this isn't necessarily a hard number, that issues like fragmentation and GC mean that you may not actually be able to allocate every last byte, but a theoretical number would still be useful.
Can anyone point me to an SDK call I've missed?

I have a SQLite db that size is over 2.6 GiB. (The db contains maps.)
This db is used by RMaps app. When move the maps to some parts at maximum zoom, the app suddenly closes.
However, there is no force close message, no report button. So, I've got an idea that it is caused by reading blocks that are beyond a certain limit e.g. max(int). Since RMaps is just using simple SQL statements, I think that the problem is not in RMaps but rather in Android SQLite driver.
Is there a size limit of SQLite database on Android?
(I have Froyo on Nexus One, but I do not think that this is just a problem of Froyo.)
UPDATE: Log output:
CODE:.......................
UPDATE2: The SQLite db is stored on SD card, there is enough space.

I have 3 video files each of 70 MB in my raw folder besides other audio files of few KBs. I am getting an installation error of insufficient space on the DROID while testing my app. I tried uninstalling apps and am now left with apps that are essential to the device.
What needs to be done to resolve this issue? I also wonder what will be the app size that i am allowed to upload to the android market?

Need to display images downloaded and extracted from a zip into the "/files" directory of the app. the images are getting in there properly as far as i can tell - i am able to extract them from the emulator and view/open them from my desktop. but every attempt, every variation of code i have found and tried so far has failed (Tag: skia / Text: --- decoder->decode returned false).
My latest construct, which does work for image files downloaded separately and uncompressed :
Code:
String imgFile = new File(getFilesDir(), "myImage.jpg").getAbsolutePath();
ImageView myImageView = new ImageView(this);
Bitmap bm = null;
try{
bm = BitmapFactory.decodeFile(imgFile);
myImageView.setImageBitmap(bm);
} finally{
mainLayout.addView(myImageView);
}
And here is the construct i am using to handle the zip extraction. I assume this is where the problem lies but i am clueless as to what i could possibly do differently and to what effect:
Code:
ZipInputStream zis = new ZipInputStream(fis);
BufferedInputStream in = new BufferedInputStream(zis, 8192);
ZipEntry ze;
while ((ze = zis.getNextEntry()) != null){
File dest_file = new File(getFilesDir(), ze.getName());
[code]....

I have few queries on Android SQLiteDatabase
1.) As normally the database stored in internal memory, can we specify the path of external storage and use it in similar way ?
2.) How to determine the size of available space of database ? I used getMaximumSize() from SQLIteDatabase class but that gives me 1099511626752
Is this in bytes ? If assumed then this seems to be too large and not practical. I am using HTC G1 to test this.
3.) How can I determine the size of an entry in table ? Or do I have to pull the whole table and manually see its size. Is it same that would be in phone storage ?
4.) Can I check if any free space available before making entry in database ? I want to prevent SQLiteFullException.

So I'm loading images from a web service, but the size of the images are sometimes smaller or bigger than other images and the visualization looks silly when I put them in a ListView in android. I'd like to fix the size of my ImageView so that it only shows a portion of the image if it's larger than a preset amount. I've tried everything I can think of setting the setMaxWidth/setMaxHeight, setting the scale type to centerCrop, using ClipableDrawable wrapping my BitmapDrawable, setting using Drawable.setBounds(). I've tried setting in the XML and programmatically, but neither worked. I'm very surprised setting max width/height didn't do anything. Below is the XML I'm using ImageView definition in my layout file
