What can I do if i lost the keystore i used to sign my application?

Solution. No you cannot update your program if you lost your keystore.To help your users find your new app and continue to get updates ....

Leave the application published. Publish the same app, with new package name and new key. Change the text for the older app explaining that the new app is called XYZ etc, that this version will not be updated anymore. Put a better backup plan into action :-)

Go to your backups to get the keystore back.

You can not update an app without the correct signature. That is for your protection and your users protection.


The apk must be signed with the same certificates as the previous version problem and solutions.


The project was not built since its build path is incomplete. Cannot find the class file for java.lang.Object. Fix the build path then try building this project error.

To solve this missing class problem. Right click on project properties, change from Android 4.03 to Android 3.1. The eclipse will automatically add the library back. Latter change back to Android 4.03. This is due to incomplete Eclipse shut down.


Build great social apps and get more installs.What’s New in 3.0 (Beta)
This release makes it easier and faster to integrate your Android app with Facebook.Ready-to-use native UI views,Simplified user session management,Better support for Facebook APIs.



Simplified user session management

This release includes several tools that simplify authentication and authorization, including a Fragment and a Button that manage login state automatically. Login state is cached in SharedPreferences by default. You can serialize sessions to support low memory scenarios; an optional Activity base class makes this automatic. The modular design handles details you don't care about while giving you more control when you need it.

Better Facebook APIs support

You can now batch SDK requests for Facebook API calls, which translates to much faster access times for parallel API requests. Callbacks and listeners are factored in to better support MVC-style programming. Facebook JSON data can be manipulated with strongly-typed interfaces to reduce coding errors and simplify reading and writing to Facebook.

Ready-to-Use native UI views

This release includes several pre-built Fragments and Views for common tasks. Built-in caching and on-demand loading makes these controls more efficient and responsive than web dialogs. Add these to your apps to build fast, native and consistent experiences for common features.

Friend Picker lets people tag friends in an Open Graph action or find other people who installed your app.
Places Picker shows nearby places with customizable locations.
Profile Picture control shows the profile picture for any Facebook object, including people, places and things.
Login controls simplify how you manage user identity and app permissions.

Mobile install measurement

With our SDK, you can measure clicks and installs for mobile app install ads. Learn more about the mobile app install ads product.

So, let start coding for facebook apps for Android.

Admob for Adobe Flash CS6 is a tricky process. To add the admobs ads in your Adobe flash based application just put the following code in the main action script.


package {

import flash.display.MovieClip;
import flash.desktop.NativeApplication;
import com.hdi.nativeExtensions.NativeAds;
import com.hdi.nativeExtensions.NativeAdsEvent;
import flash.utils.setTimeout;

//Path to iPhone SDK /Applications/

public class AdMobExample extends MovieClip {
// Admob - id
private var admobId:String = "your-admob-id";
private static const AD_HEIGHT:int = 50;
private var statusBarHeight: int = 0;
private var _adY:int = 0;
public var na : NativeApplication;

public function AdMobExample() {
// constructor code
na = NativeApplication.nativeApplication;
na.addEventListener(Event.EXITING, exit, false, 0, true);
na.addEventListener(Event.DEACTIVATE, deactivate, false, 0, true);
na.addEventListener(Event.ACTIVATE, activate, false, 0, true);
// lock the scale of the app
// so we can manage the screen sizes and
// positioning ourselves
if ( stage ) {
stage.scaleMode = "noScale";
stage.align = "TL";
//statusBarHeight = 20; //in case the status bar is visible
//if you app is full screen the this should be equal to 0
statusBarHeight = 0; // we are developing full screen app
_adY = 480 - statusBarHeight - AD_HEIGHT; //position the ad at the bottom
// call init when ready
if ( loaderInfo ){
loaderInfo.addEventListener( Event.INIT, init, false, 0, true );
} else {
// close the application
public function deactivate(e:Event):void {
// AdMob
// end AdMob
public function exit(e:Event):void {
// end AdMob
// add a short delay to make sure the app has shut down
//finalize the app.
private function finalExit():void
// AdMob Methods
public function showAd():void {
// add an event listener so we know when an ad is being displayed
NativeAds.dispatcher.addEventListener(NativeAdsEvent.AD_RECEIVED, onAdReceived);
// call showAd and pass in the size and position of the ad
NativeAds.showAd(0, _adY, 480, AD_HEIGHT);
public function hideAd():void {
// remove the ad from view
public function onAdReceived(e:NativeAdsEvent = null):void {
//Anything behind the ad will be hidden, update your layout to handle this edge case.
trace("update ui's size and position");
// end AdMob Methods
private function init(e:Event):void {
// ADMOB - initialize here
//NativeAds.setAdMode(true);//put the ads in real mode
//initialize the ad banner with size compatible for phones, it's applicable to iOS only
NativeAds.initAd(0, _adY, 320, AD_HEIGHT);
// show ad
private function activate(e:Event):void {
trace("App was activated");




You must have adactivity declared in androidmanifest.xml with configchanges. This is happen on Admobs for Adobe flash. We are unable to figure out the real problem.

Please read all related blog posts. In short, you have to update your configuration file, but to compile you should switch to Android-14 +. There is enough information around, just keep reading.


We develop for Android, Ipad, Iphone and Windows phone apps. focus is to diversify our product to other platform.

Still we are going to choose Admobs as our primary ads source. We also looking for Google Adsense Mobile Content



What is the different between Adsense Mobile Content and Admob Ads?

Admobs is for in application ads and Adsense is for Website ads. Simple Flash Presentation using flash animation.


We are developing for Windows 8 application. The default search engine is Bing. Since we love Google we want to switch back to Google. So we download the Google Search App.
