I have developped an applicaction that basically download a file from a Server via Bluetooth and store it in the memory of the mobile phone.
I read what is needed to publish and application in http://developer.android.com/tools/publishing/publishing_overview.html
and I followed the steps:
Remove any "android:debuggable" in the Android Manifest.
Remove any Log calls
Sign the file: Right click on the project->Export -> Android ->
Export Android Application ... during the process I use an
AppKey.keystored that I created before.
I apply Zipalign
http://developer.android.com/tools/publishing/app-signing.html#signing-manually
Once I finish that I upload the App to the Google Play Store.
I downloaded it with three diferent devices, with the following version of Android:
4.2.2 (It is the one I used to develop, debbug and test the App while writting it on Eclipse)
4.3
4.4
But it only works properly in the device with 4.2.2. In the other two devices the Application crash when I launch it.
This is the Android manifest of the Application, all the code is too long to upload it here. But I feel there problem must be or in the manifest or in the way I'm exporting/signing the file.apk
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.cliente_bluetooth"
android:versionCode="3"
android:versionName="1.3" >

<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
</manifest>
This is the link of the App in the Play Store:
https://play.google.com/store/apps/details?id=com.cliente_bluetooth
Can anyone find a mistake in the process of publishing? am I skipping or missunderstanding any step?
Thank you very much for your time

We have recently developed an Android app and published it via Google Play. First of all we created a beta test group, added members to it and got feedback etc from each and everyone of them. We had no problems publishing and installing this beta version on the users devices.
We promoted this beta version (API level 14+) to production and suddenly the app started to fail after installing with the following error:
java.lang.RuntimeException: Unable to instantiate application x.x.x.App:
java.lang.ClassNotFoundException: x.x.x.App
In the AndroidManifest file the name attribute of Application was the full packagename x.x.x.App. We changed this to be just the class name App and everything started to work smoothly.
However the customer decided to make the app compatible with API 10 - 13 and we made the changes to AndroidManifest file accordingly. We just changed the minSDK=10. Again we had the beta testing process with no further errors etc.
We then decided to promote this app to production and now we get the same error
java.lang.RuntimeException: Unable to instantiate application x.x.x.App:
java.lang.ClassNotFoundException: x.x.x.App
again when installing/upgrading to this new version.
What on earth is going on here - I need an explanation (if it exists) since I am not able to find any meaning of this?
EDIT: The manifest file

As stated in an earlier comment I changed name = "App" to name = ".App" and that works.
I have made an app which is pre-installed on android device of particular manufacturer. After this I have release an upgrade of application for example initial version 1.0.0.0 to upgrade version of 1.2.0.0. After upgrading the app if user restarts its phone then my application goes to the initial version of 1.0.0.0.
Don't know why this is happening ? Is there a problem in bundling the application to devices ?
Note: I am updating my app via my server and not from play store and this issue is reproducible only when app is pre-installed on devices.
In mainfest file of both the versions I forgot to change android:versionCode value, in both the versions android:versionCode=3. Is it creating problem because of this?
I have also changed the package name of Application class so is this is creating the problem ?
Manifest for first version:
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.xxx.apps.spinr"
android:versionCode="1"
android:versionName="1.0.0.0" >

Thanks for the suggestion. As #Mahmoud in comment suggested that "google play never release update for the app with the same version code", so I incremented version code of app and it worked fine. #Rat-a-tat-a-tat Ratatouille as I said in question I am not updating my app via google play neither my app is on play store so I was not able to figure this out initially. Anyways thanks for help.
So conclusion is
whenever you want to send upgrade of app always increase version code
of the app
I have developed a simple application using SDK(Android: 3.2[API-13]) for, to display Google banners.
I have tow problems in this application.
Problem No.1:
I have checked the application it runs on emulator but how can i check it that it working correctly or not?
Problem No.2:
I want to run the application on my physical Android device using Android version 2.3.3. What changes I need to do in the application to run it on my Android device using Android version 2.3.3.?
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.farman.banner"
android:versionCode="1"
android:versionName="1.0" >
<uses-sdk android:minSdkVersion="10"/>
<application
android:icon="#drawable/ic_launcher"
android:label="#string/app_name" >
<activity
android:name=".MyBannerActivity"
android:label="#string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity android:name="com.google.ads.AdActivity"
android:configChanges="keyboard|keyboardHidden|orientation|screenLayout|uiMode|screenSize|smallestScreenSize"/>
</application>
<uses-permission android:name="android.permission.INTERNET"/>
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>
</manifest
>
Ans 1 :-You have to install it in the Device and Check it.
Ans 2 :-To Run it in the 2.3.3 version,you have edit the files as below:-
project.properties OR default.properties(Only 1 of the 2 may
be present in the root folder)
Here...Change the value of target=android-10
Androidmanifest.xml
Here...Check and Change the value of
<uses-sdk android:minSdkVersion="13" /> as <uses-sdk android:minSdkVersion="10" />
Now clean and run your application and it will run in 2.3 version.
I went through all the articles about the INSTALL_FAILED_MISSING_SHARED_LIBRARY issue in Google Maps projects but I couldn't find a case similar to mine nor a solution, so here is my problem:
I have a project with an activity (com.example.googleMaps.AndroidGoogleMapsActivity) that inherits from MapView to show a Google Map and do some stuff.
I run it on a Samsung Galaxy S II and it works fine: it shows the map and does the stuff it is supposed to do.
Now.
I want to use this project as a library for another project and show that activity as the first screen of another app.
So I checked the box Is Library, I created a new android project that builds against GoogleAPI and includes the library in the Android properties in Eclipse with the following manifest:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="test.test"
android:versionCode="1"
android:versionName="1.0" >
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
<uses-sdk android:minSdkVersion="15" />
<application
android:icon="#drawable/ic_launcher"
android:label="#string/app_name" >
<uses-library android:name="com.example.googleMaps" required="true" />
<uses-library android:name="com.google.android.maps" required="true" />
<activity android:name="com.example.googleMaps.AndroidGoogleMapsActivity"
android:label="#string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
</manifest>
I run this new project on my device and I get the infamous error:
INSTALL_FAILED_MISSING_SHARED_LIBRARY
and LogCat is totally silent.
I would like to point out that the activity inside the library works so none of the well know issues should apply.
In the client project I specify two uses-library tags (one for my library and one for the Google library), I build against GoogleAPI, include the library in the Android properties in Eclipse and run on a tested device.
Am I still missing something?
I had the same problem, just remove the line:
<uses-library android:name="com.example.googleMaps" required="true" />
and it should work.
Only Use com.google.android.maps. Please remove another one.
I've published an app today mainly for my forum users to use, just a
very simple app that displays wallpapers derived from the forum.
Problem I'm having is one guy says it doesn't appear in the market,
and I've even sent him the APK to install manually but it fails.
My minimum SDK version is 4, I created it with the 1.6 SDK specified
so not sure why he can't see it or install it. He has a 1.6 Magic
handset.
So just wondering if anyone has any ideas, the app is called bocn
wallpaper, it uses internet and set-wallpaper permissions.. but I
wouldn't have thought the permissions were the problem...
My manifest is as follows:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
android:versionCode="1"
android:versionName="1.0" package="net.dbws.bocnwallpaper">
<application android:icon="#drawable/launcher_icon"
android:label="#string/app_name">
<activity android:name=".Main"
android:label="#string/app_name">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<meta-data android:value="xxxxx" android:name="ADMOB_PUBLISHER_ID" />
</application>
<uses-sdk android:minSdkVersion="4" />
<uses-permission android:name="android.permission.INTERNET"></uses-permission>
<uses-permission android:name="android.permission.SET_WALLPAPER" />
</manifest>
Please, check the supported screens: http://developer.android.com/guide/topics/manifest/supports-screens-element.html
Android 1.6 has small-screens flag set default to false. May be it causes that the application is not seen on the device of the guy.
