Mar 19, 2009I wrote an app that downloads web sites and all their assets (images/stylesheets) to "disk" and therefore stores lots of small files on the SD card.
Sometimes it fails to delete large amounts of files and afterward the file system is r/o. To analyze that behavior I tried to do the removal of the files by hand and then go from there. But that already failed.
localhost:~ mkamp$ adb -d shell mount [.. some mounts ..] /dev/block/mmcblk0p1 /sdcard vfat rw,dirsync,nosuid,nodev,noexec,uid=1000,gid=1000,fmask=0711,dmask=0700,codepage=cp437,iocharset=iso8859-1,utf8 0 0 --> R/W
Last login: Wed Mar 18 19:41:49 on ttys005 localhost:~ mkamp$ adb -d shell rm /sdcard/newsrob/a* [.. minutes of silent deletes ..] rm failed for /sdcard/newsrob/a2aade03616c28b30_113.png, Read-only file system localhost:~ mkamp$
localhost:~ mkamp$ adb -d shell mount [.. some mounts ..] /dev/block/mmcblk0p1 /sdcard vfat ro,dirsync,nosuid,nodev,noexec,uid=1000,gid=1000,fmask=0711,dmask=0700,codepage=cp437,iocharset=iso8859-1,utf8 0 0 --> R/O now
The log contained nothing but the usual gc output and random WiFi status changed mumbo jumbo.
Anybody else seeing this behavior?
There were 6.500 files in that directory. Might that be the problem? I don't access the files with queries, I always have the exact name.
Android :: Writing To System Framework In Emulator
Jul 15, 2010I'm in the process of extending monkey for software testing purposes, so I would like to replace the current monkey.jar which my own compiled monkey.jar in the emulator. The current monkey.jar is
located at /system/framework/monkey.jar.
When I try to run the following command:
adb push monkey.jar /system/framework/monkey.jar
I get the following:
'failed to copy 'monkey.jar' to '/system/framework/monkey.jar': Out of
memory'
How to replace the current monkey.jar?
This actually works if I'm running Android 1.6 in the Emulator, but nothing after that.
Yes, i've tried 'abd remount'
This is not a .jar specific issue. I can't push any type of file to /system/framework
Android :: Writing Files To SD Card Failing?
Feb 7, 2009I'm writing an podcast playing application. The application has pre- defined feeds but I want to cache the image of the feed for 30 days. However, on the initial creation of the podcast I am downloading the image, and trying to save it to the SD card using the code below:
CODE:............................
However, it keeps failing on the line k.createNewFile(); with the error: WARN/System.err(10727): java.io.IOException: Parent of file is not a directory: /sdcard/twitcast/1.jpg
I've checked and I have write permission and the SD card is mounted, and I have android.permission.MOUNT_UNMOUNT_FILESYSTEMS included in my manifest. why this keeps failing?

View 9 Replies View RelatedAndroid :: Hosting APKs Files On Site Works Only For Emulator?
Mar 17, 2009I'm currently hosting an app on my own server so my beta testers can test it. I've set up the apk MIME type to be application/ vnd.android.package-archive, and when I try to download the app from the emulator, it downloads the 53KB apk file and installs it. When I try to do the same thing from a real ADP1 device, it only loads 43KB. When I try to install it, the system says that I'm trying to install an app that already exists (called "Android System") and that doesn't require any permissions, but nothing happens when I proceed. logcat tells me
"D/asset (16379): failed to open Zip archive '/ sdcard/download/[name of the app].apk'
Bonus points! When I try to download the app from the emulator, I can see that in the accesslog of my server. Not so when I download it from the device, even after deleting /sdcard/download/* and clearing the cache through the settings. Almost as if the device was loading an old copy from a proxy server. I'm not sure which APN I'm using, but none of the T-Mobile APNs have a proxy AFAICS. Is there a way to circumvent the proxy, assuming that this is the case? And/or tell the proxy not to cache this apk file?

Android :: Android Emulator Copy Files In System Partition
Feb 10, 2010I need to copy files to the system partition of the emulator. As it is read only by default, I use the command "adb remount" to have write permissions and I can then copy the files.
My problem is that when I close the emulator and that I restart it, the copied files were missing. It's very annoying because I must write file permissions that are read at startup of the emulator (platform.xml file in /system/etc/permissions)

Android :: Application In Emulator Without Restarting Emulator In Eclipse?
Apr 8, 2009Is there a way to reload an Android application in the emulator without closing the emulator, saving any code changes, and running the emulator again?

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 RelatedAndroid :: Start-emulator Task Never Gets Emulator Running
Mar 16, 2010I 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.
Android :: Writing Authentication System
Jul 21, 2010I am currently writing the backend for a service which has 3 clients: browser, android native and iphone native. I am having a little trouble with coming up with an authentication system since I don't know what can really be done on the clients.
I am using django + twisted for the backend.
Basically, I am going to be writing RestfulAPIs to open up for the clients on both phones to call.
Now the real question is, how should I come up with an authentication system?
I have thought about using sessionids, this works very well with the browser and I can use django's integrated app for that.
However, I don't know if it's possible for both the iphone and android to obtain a unique sessionid on the handset. Should I write an API call to distribute unique sessionids?
if that's the case, is it possible for me to still use django's authentication system since a lot of the stuff here are customized? ( I am not even using a rdbms - I am sticking with mongodb, so I was on the verge of dropping django's authentication app ftm).
I have looked at foursquare's API and their basic auth method requires you to pass in user:password in every http request header. That adds 1 additional authentication each call which can kind of seem excessive.

View 3 Replies View RelatedAndroid :: Programmatically Writing PCM WAV Data
Mar 31, 2010I'm looking for a way to programmatically save an array of shorts as PCM data. I know that this should be possible, but I haven't found a very easy way to do this on Android.Essentially, I'm taking voltage data, and I want to save it in PCM format. My function looks something like this:public void audifySignal(short[] signal) {// Create a WAV file from the incoming signal}Any suggestions would be awesome, or even references. Seems like the audio APIs built in to android are more geared for directly recording from the mic, and not so much for lower level signal processing type work (at least for saving raw data to a file). I'd also like to avoid having to manually write the PCM file headers and what not.
