Android :: Unable To Open Or Create Cache For System/app/test.apk
Oct 12, 2010
When I am trying to build my application as a part of image I am getting the following error :
E/dalvikvm( 1334): Can't open dex cache '/data/dalvik-cache/ system@a...@test.apk@classes.dex': No such file or directory I/dalvikvm( 1334): Unable to open or create cache for /system/app/ test.apk (/data/dalvik-cache/system@a...@test.apk@classes.dex) E/Util( 1334): Class Not Found : java.lang.ClassNotFoundException:
But when I push the apk manually to the device (into system/app), it works fine.
I am wondering why is it so as both ways the apk is present at system/ app only.

Following the big guide and I am at the nanroid backup stage in the recovery utility. I've got
Android system recovery utility
Use trackball to highlight, click to select.
Options:
Reboot system now [home+back]
Apply sdcard:update.zip [alt+s]
Wipe data/factory reset [alt+w]
Then at the bottom it says
E: Cant open /cache/recovery/command
Thats the full screen, nothing about backup/restore

When I connect my Vibrant phone to my Win XP system and select as Mass Storage, I can see two removable drives but can't open it? When I try to double click, it says "Please insert disk in to drive D:" My son's Win 7 system accepts it fine.

In cm roms, dalvik cache of system apps are generated in /cache but those data/apps are generated in /data. Is there any way to disable this behaviour? Cache partition in our phones is too small. In AOSP and AOKP and stock roms, dalvik cache is always generated in /data no matter whether its a system app. any way to achieve this in cm roms?

Recently I switched to SDK 1.1 and it worked for a short time without any problems. Now I'm getting "Can't open dex cache '/data/dalvik- cache/system ..." error and emulator doesn't start at all. Just shows Android screen of death with blinking cursor. When I repoint Eclipse back to 1.0 r2 it works fine. I did adb shell and /data folder is empty.

I'm using the UI test monkey tool provided with android. This is a consistent error I see and wonder how I can avoid it.
Somehow the test app will rotate the orientation of my app such that the emulator window is still in portrait orientation, but the screen surface is in a landscape orientation. When in this configuration, any time you click on an EditText, a system exception gets thrown:
"The application OpenWnn (process jp.co.omronsoft.openwnn) has stopped unexpectedly. Please try again."
So this OpenWnn process is not mine, it looks like it handles display of the virtual keyboard. When in this odd orientation mode, and you try to click in an EditText, I can see the virtual keyboard try to slide in from the left side of the screen, then that exception gets thrown.
I'm not sure what orientation this is, because it's not the normal landscape orientation you get by hitting ctrl + F11. In fact, the virtual keyboard shouldn't even be trying to display itself in landscape mode? Much less from the left side of the emulator?

I approached this problem as an oh hey that's not too bad, I can write a bunch of unit tests, and I have been keeping my suite green. However as things get more involved continuous integration and testing is a great great thing to have. And then I saw oh Android has emma integration as well awesome ... and then that's where it get's iffy. So I setup Hudson and have it call the coverage target of the ant build.xml that the android executable in the sdk can generate. And then it hits me. adb -s <emulator> shell am instrument -w ... will never return a result code that is not 0 ... because adb technically exited cleanly and usually will regardless of how the shell command that executed did..............

So, has anyone with this error been able to push the update through? i read (cant find it now) that this has something to do with OTA updates. the way i understood it was, this is a folder Verizon looks for during an update. so if thats true would it cause me to get stuck in on the MOTO LOGO screen?

I'm looking for a method or an application for android tablet, which allows me to quickly reset the device deleting any data (from the Internet cache, and the cache to the photos of the various programs such as facebook, twitter etc ...) and that does not allow any modification of the operating system. I need this solution because I have a restaurant and I want to put a tablet on each table for guests to make him see the menu (full of photos and videos), surf the internet and play with the kids.
is there an app that allows this? or is there a quick way to do this, such as a multiaccount management ? I remember, for example, that for windows there are applications that completely erase any unauthorized modification, files and cache, at the time you restart the operating system.

Just started developing apps and am having a small problem. I can test the apps on the emulator but I cannot test them on my physical android device. When I am asked to select a running device I get a device listed as: Serial Number/name:? AVD name: N/A Target: unknown etc,
It seems that my device is being picked up but not able to be used. When I try to run the app I get an "Must set android.target.avd" error.
Is there something I am missing?
I am using netbeans 6.7.1 on Ubuntu 9.10, everything up to date. I have a G2-Touch from T-mobile, if someone tells me where to find it, I will post any other needed information.

After reading the thread on here about not needing a task manager, I removed mine and downloaded system panel just to keep an eye on whats always running and be able to kill any rogue apps. However, whenever I open system panel lite, its only ever the one that seems to be using the most CPU in the foreground apps, with it having the most bar full on the left. So what I'm confused about is that whether its normally just using a lot of my CPU to keep track of things, in which case I should uninstall it, or whether its a case of it showing up as using so much because I am using it at the time of checking to check the CPU usage.

Android should become more like Windows. Android should be able to detect and recognize the different hardware configurations and adjust itself accordingly. This way, you hit two birds with one stone. No more fragmentation. No more differences in the UI, Custom UI will be entirely optional.
All the manufacturer has to do is make the hardware and provide the hardware drivers to Google. Simple as that. Everything will be so much easier. Phone manufacturers will be able pump out devices like crazy without any worries. Software developers won't have to worry about device compatibility. Come on Google, lets do it.

I am trying to write an app that requires different PDF files to be opened and displayed on the E-Reader side of the eDGe's dual screens while the app is running on the LCD side. I've been using Better Terminal Emulator to cruise around the eDGe's file system but can't seem to find the command that opens PDF files. Does anyone know it or is there even one?

I am trying to use
SQLiteDatabase.openDatabase( "/data/data/edwin11.myapp/databases/myapp.db", null, (SQLiteDatabase.CREATE_IF_NECESSARY | SQLiteDatabase.NO_LOCALIZED_COLLATORS));
To create/open a database instead of making use of the SQLiteOpenHelper (because I want to pass in the flag SQLiteDatabase.NO_LOCALIZED_COLLATORS. However, I am getting this exception for that line of code:
04-18 09:50:03.585: ERROR/Database(3471): sqlite3_open_v2("/data/data/edwin11.myapp/databases/myapp.db", &handle, 6, NULL) failed

Doing some testing just before that line of code (using File.isExists) shows that the file /data/data/edwin11.myapp/databases/myapp.db does not exist. Would that be the cause of the error? (Or am I just using SQLiteDatabase.openDatabase the wrong way?) Would it help if I create the file beforehand? (Shouldn't that be taken care of by the SQLiteDatabase.CREATE_IF_NECESSARY flag that I passed in?) If creating the file manually is the way to go, is it just an empty file, or do I have to write something to it?

No matter what I do I am unable to open a file, either in my app's data directory or on the sdcard and also in a folder on the sdcard. To test I placed a test.txt file in all three directories.When I do listfiles, I get the correct list of files set in an array. I've even tried getting the list and filtering out a specific file and try opening it that way and just trying the first item in the array. Is there some security that may be set that is making it so I cant open files? This is not the emulator, it is on a device.
