I'm trying to cache an image obtain from a webside. However, CacheManager.getCacheFileBaseDir() always returns null. Do I need to create the cache folder in the android emulator? if yes, how can I do it? in which directory i need to create it in?

I've experienced a strange issue running applications on the HTC Desire.
When I call getApplicationContext().getCacheDir() or getApplicationContext().getFilesDir() from my activity this always returns null. In the emulator /data/data/com.myapp.android/cache respectively /data/data/com.myapp.android/files is returned.
Because of that I'm not able to use the webview class as it tries to create cache files and crashes with a null pointer exception. The logs:

I noticed that other apps have issues as well. For example the google finance app logs the following message:
CODE:.............
Why I cannot create folders in this directory?
Is there a possibility to set the fileDir and cacheDir paths to the sd card or somewhere else? I looked at some classes like Context, Webview and CacheManager but I could not find a way to change it.
Do I need to set a permission to create cache files?

I'm honestly holding out for some of the new 1 Ghz machines to come out and do some comparisons. Anyway, I would imagine one would easily be able to make whatever folders they choose on an sd card, but on the emulated one, I can only seem to push entire folder contents or single files to the root. The adb help doesn't appear to have a command to make a folder. Is this not possible, or am I just missing something?

I'am trying to use a large DB file. It's as big as >8MB. I built it using sqlite3 in Mac OS X, inserted UTF-8 encoded strings (for I am using Korean), added android_meta table with ko_KR as locale, as instructed above.
However, When I debug, it keeps showing IOException at

I suspect it's caused by trying to read a big file. If not, I have no clue why.
I tested the same code using much smaller text file, and it worked fine.
Can anyone help me out on this? I've searched many places, but no place gave me the clear answer, or good solution. Good meaning efficient or easy.
I will try use BufferedInput(Output)Stream, but if the simpler one cannot work, I don't think this will work either.
Can anyone explain the fundamental limits in file input/output in Android, and the right way around it, possibly?

I'm implementing an image cache system for caching downloaded image.
My strategy is based upon two-level cache:
Memory-level and disk-level.
My class is very similar to the class used in the droidfu project
My downloaded images are put into an hashmap and the Bitmap objet is wrapped inside a SoftRererence object.
Also every image is saved permanently to the disk.
If a requested image is not found into the Hashmap<String,SoftReference<Bitmap>> it will be searched on the disk, readed, and then pushed back into the hashmap. Otherwise the image will be downloaded from the network.
Since I store the images into the phisical device momery, I have added a check for preserve the device space and stay under a 1M of occupied space:
CODE:.................
This method is called sometime afte a disk writing:
CODE:..............
What I'd like to add is the same check on the HashMap size to prevent it will grow too much. Something like this:
CODE:.....................
My question is:
What could be a right MAX_MEMORY_SIZE value? Also, Is it a good approach? A good answer also could be: "Don't do it! SoftReference is already enough"

Is it possible to change the emulator's behavior to create lock files somewhere in /tmp (using some hash of image path as lock file name)? I am OK to try this myself: which repositories from https://android.git.kernel.org/ are necessary to rebuild the emulator alone, and where in the sources is the code responsible for image locks?
I need to run several emulator instances to test my application. When i try to run instances using emulator -data <path> option, the emulator crashes.
I got a MS Visual Studio window informing that emulator throws a "unhandled win32 exception".

The emulator runs normally without "-data" option.
I am getting the following error when I try running my program in the emulator:
emulator: ERROR: the user data image is used by another emulator. aborting`
Is there a way to reload an Android application in the emulator without closing the emulator, saving any code changes, and running the emulator again? If I make even a simple change to the layout, it takes about 30 seconds by time I run it in Eclipse and Android "boots", and I can unlock the emulator to run the application. Is there any way to shorten this time when making changes, or is it something I just have to deal with?
View 3 Replies View RelatedI downloaded the most recent version of Android for linux (android-sdk_r05-linux_86.tgz). I was trying to use the the Android Ant task(s) for packaging, building, and deploying my code. I should mention that I'm running AMD64, but have the 32-bit libraries installed. The Android Ant tasks are all broken.
First, the start-emulator task never gets the emulator running. It does get past starting adb, but then just sits there.
Second, the SDK is missing the aapt binary in the tools directory. So, the example notepad sample application will not even package correctly.
I have all the dependencies configured for Android. I can run it from the command line just fine.I assume the Ant code is out of sync with the recent SDK updates. Can anyone shed some light on this problem? At this point, I'm considering writing my own Python scripts to interact with the Android SDK. Ugh.
