I am having this problem while running my application in emulator.When I run application it shows in console this error:
[ERROR]Error reading data file
and then nothing happens.Don't know what can be the issue, tried it many ways deleting all virtual AVDs and cleaning up the project again and again but not working anyway any solution for that? I am using 2.1.1 titanium SDK and android V8 (2.2).
sometime this also show this error in console:
[ERROR]No building apps, No launcher activity.
Did the application run before?
Have you tried a clean build or deleting the build directory to perform a full rebuild? You can also have a look into the logcat provided by DDMS to search helpful information.

I've been working on a Xamarin project for a few days and have been testing it fine, but today it has suddenly stopped allowing me to debug the app, either via Live Player, or by connecting my smart phone via USB.
The only error I am getting, as far as I can see, is
Failed to debug your app
I've not got a way of testing it on iOS devices, but the built-in Windows Phone emulator runs the app fine, albeit with an error in my code popping up now and then.
What could be causing the Android version to stop debugging, or how do I at least fix it?
There are a couple of steps that can help with that issue:
Clean the solution and exit visual studio
manually delete the .vs folder in your solution directory
Delete the /obj and /bin folders in your shared code, and in each project for the platforms you are using
if you are developing for iOS, sometimes it helps to restart your mac
Start Visual Studio
Rebuild your shared code project
Rebuild every native project
Beyond that also make sure that you are using the latest versions of Visual Studio, Xamarin and Xamarin.Forms on all your computers, and that the nuGet Packages your project is using are at the very same version each in shared and native code
Also check, if your app isn't throwing an unexpected exception during its initialization. Especially if not caught, it can happen that your app crashes before your code gets executed at all.
In addition you may find further information about what is going on at Help -> Xamarin -> Open logs or in the device management in XCode (iOS only)
Try this :
Close visual studio if open.
Open App Data and then go to
(a) Local\Xamarin
(B) Local\Xamarin\Xamarin.Android
Empty these folders.
Open your project and then try to build your application.
Not a proper solution, but I uninstalled and reinstalled Visual Studio. This seems to have fixed the problem, but I've still no idea why it stopped working in the first place.
So I have just started my first app in which I have a button and when user clicks on it then it just print the message.
But when I build the app and when I run that app on android studio's console then after opening it crashes and then it stops working.
Meanwhile I have searched for the error and they suggested me to see logcat table or the text file in which I can easily see the errors but after it I am stuck because I have no idea that how can I solve such problem.
Please help me with it.
Not sure how capable you are with android and you haven't given us much info to work with.
could you post a brief description of the logcat from launching the apk to the apk actually crashing?
the logcat is gonna be the best option to diagnose it.
Are you using the android sdk and emulator?
Have you updated the resources and api's?
If you go into the resource list there should a online repo with a whole lot more SDK bits you might find help.
What api's and android version is your apk built from and is your emulator emulating the same android build?
Could be the apks GUI resolution or script related, have you checked through it all?
Microsoft visual studios has a very good debug system and trouble shoot but I'm not sure if android is compatible as I've only used wp8 on it. Worth finding out though.
I recently switched from Eclipse to Android Studio because I read that it is now the official IDE for Android application development. I downloaded and installed the latest version (1.0.2) for Windows. When using the program for the first time, I decided to create a test application to see if the program was working correctly. Unfortunately, it was not. Once I clicked the finish button to complete the New Project Wizard, A loading bar showed up that said Gradle: Build. This is where the program gets stuck. There is no error message and it appears that the program is running fine, however the build never actually completes. I am never given my MainActivity.Java class, or my activitymain.xml document. If I click the cancel button, the program freezes and I have to use the TaskManager to kill the program. If I re-enter the program and choose to open an existing project, my project will be there. However, upon trying to open the project, I am greeted with the same Gradle: Build loading bar.. I have been searching for an answer for the last 3 days and nothing has worked. Any help is greatly appreciated!
Things I have tried:
Simply letting the program sit for a while to see if it was actually downloading something and was just really slow. I let it sit for 45+ minutes before killing the program.
Uninstalling and re-installing Android Studio
Restarting my computer
Turning off my firewall (Kaspersky)
Running the program as an administrator
Connecting to a different network
Disconnecting my computer from any networks (to force the program to build in offline mode)
Manually downloading Gradle from the link that Android Studio attempts to use when it gets stuck and telling the program to use that file instead of downloading another one.
(I went to this link https://services.gradle.org/distributions/gradle-2.2.1-all.zip, downloaded the file, unzipped it, went to Gradle settings in Android Studio, checked the Offline work checkbox, and finally set the service directory path to my unzipped Gradle folder.)
Hopefully I have given enough information and made it clear what my problem is. If not please tell me what else I need to explain so I can get this issue resolved. Thanks!
Please note I am working on a 64 bit machine running Windows 8. Also, I use studio64.exe
to run the program.
From the discussion we had in the comments, it does not look like you have your gradle on your windows path.
Please change the below to point to your gradle install:
set GRADLE_HOME=C:\<installation location>\gradle-1.11
set PATH=%PATH%;%GRADLE_HOME%\bin
After this, verify that in the terminal running the following works:
gradle tasks
once you get this working, you will want to run the following in your project:
gradle wrapper
This will produce a .bat file which you can then use to run gradle through the wrapper, letting you support multiple native gradle installations.
I've been having issues with Cordova. I can add the android platform but when I try to build an error appears saying that build.template is not in C:users\scott\devolopment\adt-bundle\tools\lib\build.template as seen in the image below
However I do have build.template in that location as seen below
So I'm confused as to why it cant find it. I have appended the tools and the platform tools to my path. I've tried closing the command prompt and reopening it as well as restarting the computer. However I still get the same error every time. Anyone have any ideas
I have made a PhoneGap/Cordova based application, that seems to work fine when tested with Chrome + Ripple.
When I'm trying to install it to my Android device(which is ADB configured, and shows up in Eclipse SDK), I get the INSTALL_PARSE_FAILED_INCONSISTENT_CERTIFICATES error.
By reading existing posts on the same issue, I understand that it has to deal with re-installation of the app.
But, this is the first time I am trying to run this app on any device, and I don't see how re-installing might solve the problem.
Any advice on resolving the error would be much appreciated.
Look for another app in settings->apps->downloaded that may have the same package name and uninstall it.
