Android :: IOException When Running Android Projects In Eclipse
Jun 17, 2010
Every time I try to run an Android project from Eclipse with the Android plugin (Run -> Run), the emulator starts up just fine, but the upload fails, and the Console puts out this error message:
[2010-06-17 08:17:55 - HelloAndroid] Failed to upload HelloAndroid.apk on device 'emulator-5554'
[2010-06-17 08:17:55 - HelloAndroid] java.io.IOException: Unable to upload file: Local file doesn't exist.
[2010-06-17 08:17:55 - HelloAndroid] Launch canceled!
It seems as though the apk compilation is failing, but there are no other errors in the Console at all except for a lone warning about the project not specifying an API Level requirement:
[2010-06-17 08:17:55 - HelloAndroid] WARNING: Application does not specify an API level requirement!
[2010-06-17 08:17:55 - HelloAndroid] Device API version is 8 (Android 2.2)

I always face this problem in my eclipse. I would like have a copy of the apps in all the versions of SDKs/NDKs. And once I have a project in eclipse, and if I have to import the same project from a new location, I get the message saying "Can't import, project of the same name already exists". Is this how it is? We cant import the same project from its 2nd location in eclipse? Everytime I delete the project from old location and put it in new. I know, it is a very unacceptable approach).

I have problems with the following: I want to create to applications. One with a Android service and one with a Activity that will use functions on the Service. Before I splitted this in to applications I got everything working in one application. I can call functions (that are definned in the aidl - file) on the service without problems.
Now the problems coms. I splitted the application into two parts, a Service application and Gui application. The bindins to the service (in the gui application) works and I see that the service is getting created. Then in the onServiceConnected function of the ServiceConnection class I created the following:
mService = IMyService.Stub.asInterface(service);
And this gives me the following exception:
03-16 13:53:05.549: ERROR/AndroidRuntime(881): java.lang.NoClassDefFoundError: MyPackage.IMyService$Stub
It looks like he can't find the Stub class in IMyService. But the Stub is part of the java file generated out of the aidl-file. Why I get this exception or how I can resolve this?

Here is the situation.
I have a java project "LicenseGenerator" in eclipse that depends on commons-codec. I have therefore added the commons-codec jar file to the build path. I have Junit tests and everything is working fine. I have made a different project in the same workspace - which happens to be an Android project - that needs to use my LicenseGenerator classes. I added LicenseGenerator to the "projects" tab in the build path - the classes were recognized and I was able to use them.
Everything compiled and ran. However, when the part of the LicenseGenerator that used the commons-codec was called from my Android project I got the following error.
Could not find method
org.apache.commons.codec.binary.Base64.encodeBase64URLSafeString,
Referenced from method
This basically tells me that the commons-codec was not packaged which the Android project, so I added the commons-codec to the android project as well but the same error appears.

I have a library-only Android eclipse project (no main class, only library classes) that I want to include in my main Android Application project. I went to the Build Path and added the library project to the "Required projects on the build path" on the Projects tab, and checked it on the "Order and Export" tab. However, when the application is run, it emits VerifyError exception, because the class from the library project didn't happen to be packaged together in the apk.

For some unknown reason when I now try to create a new Android project in Eclipse (Ganymede running on Windows) it fails to link to the android.jar in the SDK (1.0_r1). This has never happened before, and all my existing projects continue to resolve Android components just fine.
Error: "Cannot create linked resource '/.org.eclipse.jdt.core.external.folders/.link0'. The parent resource is not accessible."

How can I attach Java source to an Android project? I'm able to browse java source for a Java project, but not for an Android project. I modified project properties and add Java source in "Libraries" section, still not working.

I have 2 android applications that share 95% of their resources, layouts, strings etc. only a few jpg's are different.
How can I share resources between the different Eclipse Android projects, so as to avoid resource duplication ?

I have notices following:
If I have a project with minimum files in res folder, the project saves quickly, compiles quickly and launches quickly. But if I have a lot of resources, my project is saving, compiling and launching during relatively long period of time. This is really frustrating if you do some minor UI updates, and you have always wait Eclipse to generate R file etc.

When I make a new project the .java file is not generated. I can run the project, but it does not run in the emulator or anything. It did use to work before then it stop working. I tried deleting the folder and all project files. After that I reinstalled everything but I am still having problems.

I'm working on two projects. One is essentially a library, and the other is an application using that library. Now from the application project, I want to use the library's classes, so I added that project to the "required projects" under java build path. It seems to compile fine, but at runtime, I get this error:
07-27 11:26:57.037: ERROR/dalvikvm(741): Could not find class 'interdroid.contextframework.ContextManager', referenced from method com.bartvanwissen.contextframeworktest.MainActivity.onCreate
Apparently, the library project's classes are not added to the apk file. How can I make sure they are included? Since I'm working on both projects at the same time, I would like to prevent having to create a jar file every time I want to test something.

An Android Java project placed in a git repository and built in an Android tree in /packages/apps needs to have the project files located at the root of the git repository.This is problematic for creating a complementary Test project, which should ideally be included in the same git repository so commits are atomic for both code and tests. Eclipse gets very unhappy if you include the Test project as a subdirectory.Is there an appropriate approach for dealing with this other than creating a second repository?

I just started to play with android dev and java+eclipse is pretty new to me. I managed to create simple project and run it on my device. Now I want to create simple game (more of them actually) and I would love to use shared code base for all of them (game loop, initialization, etc..). Problem is that I have no idea how to correctly do this. I created android project called engine with all basic stuff that I need and made it work on device. Now I tried to create another project in same workspace called mygame. Main class (activity) of mygame is MyGameApp which inherits from EngineApp (main activity of my engine project) which inherits from Activity. I added engine project into required projects in mygame build path tab in properties. Problem is that when I try to run this project it crashes on ClassNotFoundException trying to find my MyGameApp class.

I cannot run android junit tests for classes sitting in main android project that implement interfaces that reside in other included projects. Depending on SDK version I get different errors: from "Test run failed:" on 1.5 and 1.6 and spurious process death to a more polite "NoClassDefFoundError" on SDK 2.0. This happens only on instantiation of classes that reside in the Android project and implement interfaces residing outside that android project. There is no problem instantiating classes that do not fall into this category (i.e. android only or library only classes).
Android project by itself works fine with these classes - it is just the test set-up doesn't and project inclusion/classpath seems to be ok. Test project includes all projects that main project includes. NoClassDefFoundError makes little sense here given that the classloader can see and instantiate classes sitting right next to the ones that do not work. Did anyone else run into this or found a way to set-up android based tests in a multi-project set-up? Below is more detailed set-up and test explanation: 1) Library project: FooLib public interface IFoo { ... }

I have issue with running apps in emulator from Eclipse. I was using tutorials from http://developer.android.com: http://developer.android.com/guide/tutorials/hello-world.html http://developer.android.com/resources/tutorials/hello-world.html
Also, i tried running sample projects delivered with SDK. Whenever i run project, emulator loads but my project is not installed. And when emulator loads, nothing happens. I was searching on web a bit, and i figured that if i restart 'server' it continues to install my app:
android-sdk ools>adb kill-server - D:...android-sdk ools>adb start-server - * daemon not running. starting it now * - * daemon started successfully *
Log:
New emulator found: emulator-5554 - Waiting for HOME ('android.process.acore') to be launched.

I set up Eclipse as directed on the android development site, and ran the emulator after building one of the sample apps. The emulator comes up and just displays some text and doesn't function after that. The program doesn't even seem to run. I am following the steps on the site exactly (or at least I think I am), but no matter what program I try to run on the Emulator it never seems to function (just displaying that same message).

How to run the emulator within eclipse without using ADT. All I want to do is run the emulator with -partition-size option of the emulator and you cant do this by default. Im sure there might be a tricky way of doing this but googling doesn't give me any clues. does any one know ? I also thought about running the emulator as part of a script and call the script within eclipse.

When launching my app from within Eclipse, sometimes the running emulator is found and displayed in the launch dialog, sometimes it isn't?! Killing adb, the emulator and Eclipse usually helps until it happens again. Any idea why this is? I see this behavior since the launch of Android. I am running on Mac OS X. And it happened on Leopard as well as Snow Leopard.

Just upgraded to 3.6 after this whole Sun/Oracle JVM fix/debacle and I notices that 3.6 EE runs super, duper slow. So slow to the point that code assist is unusable. Here are some changes I made to the config to make it operate a lot better:
eclipse.ini: replace the end with this:
-Dosgi.requiredJavaVersion=1.6
-XX:MaxPermSize=512m
-Xms128m
-Xmx1024m
And turn off JAX-WS Proposals in Content Assist Window > Preferences > Java > Editor > Content Assist > Advanced. I also disabled JPA and PDE, but you might need them depending on what you're doing.

I am trying to write an android application and my workflow is as follows:
Write some code
Click run as Android Application
Eclipse then starts the android emulator
Install the app on the emulator
Run it
It seems to me that there is no need for it to start an android emulator(3) each time and to kill it. It'd be nice if there was a way an android emulator always running and eclipse just installs/uninstalls the app instead of making me wait every time.

I setup Hello Android sample app on my Eclipse ( Windows XP). ADT got installed correctly. All post installation config also looks good. I setup HelloAndroid project.
I run first time . It was successfully run and connected to emulator , produced desied message on emulator.
What happened , when i tried to run same program again it stopped working at console trace ( see below console trace). I tried to reset Adb from debug view. Also tried to kill Adb from command line. I completely exited from Eclipse and restarted. At last completely rebooted PC but no luck. I never changed my code a bit after running successfully first time.
Hello Android stops at following message.
[2010-07-08 16:08:59 - HelloAndroid] Starting activity com.example.helloandroid.HelloAndroid on device
[2010-07-08 16:09:02 - HelloAndroid] ActivityManager: Starting: Intent { act=android.intent.action.MAIN cat=[android.intent.category.LAUNCHER] cmp=com.example.helloandroid/.HelloAndroid }

I'm trying to parse an XML file from res/raw or assets/ using the javax SAX parser. When the file is too large (~ 1MB), the parse(...) method throws an IOException without further information, such as message or inner exception. When I reduce file size to e. g. 600 kB, it's working again.
