unsigned APK can not be installed - android

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.

Test Android App over Remote Desktop

When I'm away from my computer, I like to use TeamViewer to access it and work on my Android apps. I save unsigned .apk files to my Google Drive so that I can test them while on the go, too. I download the .apk files to my Android device through the Drive app, but I'm having an issue.
When I go to install the App after downloading it from Google Drive, Android asks me if I'd like to install the App. When I click yes, it begins the install process but then exits with an "App Not Installed" error. There doesn't seem to be any other indication of what happened.
I've tried this with several of my .apk files, but they all give me the same issue. If it helps, these are apps I've previously downloaded by running the app with my android device plugged into my computer. I made sure to uninstall the app before trying to install it through the .apk file. I'm testing on a Google Nexus 7 32GB.
Any help would be much appreciated. Thank you!
To me, it sounds like you are trying to install an APK that is signed with a different certificate than the one installed on the device.
Run logcat, and you will see a message with information on exactly what is happening.
Have out tried installing your unsigned APK through ADB? This should let you see any errors there are in installing that APK, such as security settings.
According to a now-deleted(?) comment, you were trying to install an unsigned APK.
Alas, you cannot install an unsigned APK. Android -- emulators and devices alike -- only run signed APKs.
What comes out of the normal development process is an APK signed with the debug signing key, not an unsigned APK. There is a concept of an unsigned APK, but you have to go out of your way to create one normally, and it's usually just an interim step en route to signing it.

How to run an Android app which will run in any system without using Eclipse

I have created an Android Calculator app in Eclipse. If I want to run my app I need run it through Eclipse. But I want to run my app without Eclipse in any system as normal apps run, just download it and run.
If any one knows how to do this, please help me.
You probably want to take the .apk file in your bin folder. This file is your entire app packaged together.
You can run & install this on other Android phones, but they will have to have enabled "unknown sources" in application settings.
Otherwise, you'll have to publish to the app store, from where the entire world that owns an Android device can download it directly.
app run without eclipse in any system as a normal apps run
may I know how the normal apps run?
it need any emulator or device.
you can run the .apk file without eclipse also!.
download the Android SDk and create an emulator thru avd command and install any app.
the other way you can do by 3rd party software called BlueStacks App Player
this software is only for mac and Windows download here
Inside bin folder of your Calculator app project located on Hard disk there will be .apk file which you can transfer to your device then open file browser whichever you have that will allow you to install and run your application cheers.
Do you mean you want to install it on any device from your system, without the need to run Eclipse?
The command would be something like "adb install bin/MyCalculator.apk". Once you do that, your app is installed just like any other.
Do you mean you want anybody to install your app on their device? Your best bet is to just put it on the Android Market. Don't forget to generate a real signing key (don't use the Eclipse debug key) and sign your app properly before uploading it to the market.
If you don't want to use the market, then you can put the apk file on any web page, and have people download it with their browser. Then they go to their device settings and enable "Unknown sources". After that, they can run their browser, go to "Menu > Download" and select the apk they just downloaded.
Or, you can send the apk file to someone directly, and have them attach their device to their computer, enable USB, and copy the apk to their /sdcard directory somewhere. Then they launch a file browser (they'll have to install that first) and navigate to the apk file. I think that will allow them to install the apk on their device.
I think that should cover it.
You should generate the .apk file, and install it on any device you want..

How to build an APK file in Eclipse?

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..

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.

How to create .apk files for 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:
