How to create .apk files for Android? - android

I tried right clicking on my project (in Eclipse) android tools->Export unsigned application package.
I then moved to .apk file to my Samsung Galaxi S device and tried to install it,
I got a message saying the app was not installed.
Did I do something wrong in creating the .apk (what could be the problem)?

Check this doc.

If you want to install the application with debug key then you need device driver(Kies in your case) installed on your development machine. Then attach your device to your machine through USB port. Close emulator and run your Android application on your device using Eclipse. The signing procedure mentioned in previous answers is mandatory only when you are uploading your application on Android Market.

you should Export signed Apk file:

Android Unsigned App not able to install on device

My app able run on simulator and I export it as Unsigned App.
On my phone's Setting-->>Applications--->>Unknown sources checked.
I download the .apk into phone storage through USB.
Then under File Manager, I found that stored .apk and hit install button and it try to install,
But finally it says Application Not installed. but why? wht's wrong?
Also I try ./adb install -r myapp.apk but it said error:device not found
I have never tested an app on a device by using your method... When I am NOT debugging on my device using usb and I just want to install it on my phone, I do the following:
If you have run it on the emulator then there is an .apk file in the bin directory of your project.
Move that .apk to your phone via usb or another method (I use dropbox).
Open the .apk and install on your phone.
The previous answers are correct, it must be signed. But by doing my method it will be signed with your debug key.
You will obviously want to actually sign it with a real key before publishing it to the market.
All applications must be signed in order to install on emulator or real device, check out the official dev guide signing your application:
All applications must be signed. The system will not install an
application on an emulator or a device if it is not signed.
To test and debug your application, the build tools sign your application with a special debug key that is created by the Android
SDK build tools.
Specifically how are you getting the APK to the device? Try dab install <path to APK>. Also, you can install APKs from the Android browser by uploading it to any web server and navigating to its URL.
You must export and sign with a debug certificate before installing. Read about publishing.
If you are using Eclipse, you don't need to export your app as "unsigned apk". Simply enable "Allow Unknown Sources" on the phone, and right click on project and hit "Run As".
Unsigned apks are generated by signing them with the debug.keystore key that's stored in the Android SDK. It could be possible that his key is corrupted. To verify, check to see if any other project also gives a similar problem. To resolve th key corruption, delete your SDK and install again (shouldn't take more than 15mins).
In case other projects work fine, which means your debug.keystorekey is NOT corrupt, you need to uninstall any previous versions of this app on your phone and restart your phone.
It could also be possible that the adb server could be messed up. In that case, restart your Eclipse or do adb kill-server from command line.
Also, seems like other people have faced similar issues. Did you search similar StackOverflow questions and try out the solutions? Here's one: 'App not Installed' Error on Android
Unsigned APK can be installed in real mobile devices for purpose of testing.
Just follow these steps on images:
Locate the APK and send it to your mobile through gmail etc..

android - app installation

i developed a application and it works fine on the emulator, so tried to install it on my phone using a .apk of the file
(NOTE: It is a unSigned one).
on installing the app on the phone, during installation i get a error as installation failed.
(NOTE: Other applications from the market are installing without any errors, the ones downloaded from the internet are working fine, but one developed by me aren't)
tried to debug the application on my phone using USB debugging.
the app gets installed fine by USB debugging.
Still can't figure out how to install using the .apk file.
Thanks in advance. :)
You have to sign your application if you do not want to install it using adb. If you use Eclipse and ADT just click on your project folder, choose Android tools -> Export Signed Application Package. Then provide access (or create new) to your keystore file and choose key. After you've signed an application you can, for instance, send it by email and install it on a real smartphone.
What you can also do is copy the .apk to the phone via the ISB cable into the sim card out the SD card. Then you don't have to send any emails to yourself.

Error for install .apk file on my real device ( htc wildfire s) and emulator run without my application

I'm new in Android programming after compile my project in eclipse without error I see error for install .apk file and emulator run without my application.
It all depends on what you're doing. Could you describe a bit more?
As in, what kind of error does it give you, is USB debugging enabled on your phone? You should take a look at some of these base things.
EDIT:
If you want to install your application to your phone (seperately from Eclipse and debugging), you have to generate a signed APK file. To do this, you right-click your project in Eclipse, open the Android Tools submenu and click Export Signed Application Package. You will be asked for a keystore, make one if you don't have one. You use your keystore credentials to sign the application this way and this will make it installable on a real device.

Android. Can't install developed APK on phone when Ok on emulator

I am developing android application under Eclipse. It is running in emulator just fine under different platforms. I have checked android version on friend's telephone, also in eclipse and successfully ran it on emulator too. Created unsigned application package using eclipse.
Installing on phone.
After installation he got error message "app not installed" and button 'Done'. Uninstaller found my program and got error '%program name% failed: invalid URI'. In my xml files I didn;t see nothing that can help with this error.. What does it mean? :(
An unsigned apk can't be installed anywhere.
You have three solutions:
go into the bin folder and use the apk that is stored there (this apk is signed with your debug certificate)
connect the phone via usb to your pc and install it using eclipse (Run as -> Android Application -> select the device)
Create a signed application. You need a valid keystore for that (Eclipse helps you creating one)

unsigned APK can not be installed

I am trying to distribute my application to some people for testing.
I have installed it on my Desire directly from eclipse and it works fine.
To create an APK-file, I choose "Export Unsigned Application Package" directly from eclipse, and then an APK file was created. I emailed it to myself and downloaded the file to the SD-card. But when I try to install it (using ES File Browser), I get a message saying "Application not installed".
(I have already checked the "Allow installation of non-Market application" on my phone)
Any ideas?
Yeah I found the problem, see my answer below:
I did not know that even with the "Allow Installation of non-Marked application", I still needed to sign the application.
I self-signed my application, following this link self-sign and release application, It only took 5 minutes, then I emailed the signed-APK file to myself and downloaded it to SD-card and then installed it without any problem.

You cannot install an unsigned application on a phone. You can only use it to test with an emulator. If you still want to go ahead, you can try self-signing the application.
Also, since you are installing the application from an SD card, I hope you have the necessary permissions set. Do go through stackoverflow.com and look at questions regarding installation of applications from an SD card - there have been many and they have been asked before.
Hope that helps.
You can test the unsigned-apk only on Emulator. And as its step of application deployment and distribution, you should read this article atleast once, i suggest: http://developer.android.com/guide/publishing/app-signing.html.
For your question, you can find the below line in above article:
All applications must be signed. The system will not install an application that is not signed.
so you have to have signed-apk before the distribution of your application.
To generate Signed-apk of your application, there is a simple wizard procedure, click on File -> Export -> Android -> Export Android application.
Just follow these steps to transfer the apk onto the real device(with debugger key) and which is just for testing purpose. (Note: For proper distribution to the market you may need to sign your app with your keys and follow all the steps.)
Install your app onto the emulator.
Once it is installed goto DDMS, select the current running app under the devices window. This will then show all the files related to it under the file explorer.
Under file explorer go to data->app and select your APK (which is the package name of the app).
Select it and click on 'Pull a file from the device' button (the one with the save symbol).
This copies the APK to your system. From there you can copy the file to your real device, install and test it.
Good luck !
I cannot install an apk build with "Export Unsigned Application Package" Android SDK feature, but i can install an apk browsing the bin directory of my project after the project buid. I put this apk on my sd on my HTC Wildfire phone, select it and the application install correctly.
You need to allow your phone to install unsigned apk.
Good Luck.
You could also send your testers the apk that is signed with your debug key. You can find that in the bin folder of your project after building in debug mode.
An unsigned application cannot be installed. When we run directly from eclipse, that apk is signed with debugger key and can be found in bin\ folder of the project. You can use that for test purpose distribution also.
