I know there are a lot of questions already. I've been going through all of them, but still I`m not able to solve my issue.
I was asked to extend an already existing android app, which is based on PhoneGap. I checked out the sources from a repo, and realized that the first developer included some library as dependency. i followed the instructions here, build in the core of ZXing isn't any build.xmlfor ant.
I went through the instructions at XZing Getting started, build my own core-2.3.jar tried to include, but failed. Same with the ready-deployed core.jar from the page
I included the the jars in the /libs folder, imported is a external jar, nothing worked. I`m getting following error everytime:

The manifest-declaration looks like this:
<!-- ZXing activities -->
<activity android:name="com.google.zxing.client.android.CaptureActivity"
android:screenOrientation="landscape"
android:configChanges="orientation|keyboardHidden"
android:theme="#android:style/Theme.NoTitleBar.Fullscreen"
android:windowSoftInputMode="stateAlwaysHidden"
android:exported="false">
<intent-filter>
<action android:name="com.phonegap.plugins.barcodescanner.SCAN"/>

</activity>
<activity android:name="com.google.zxing.client.android.encode.EncodeActivity"
android:label="#string/share_name">
<intent-filter>
<action android:name="com.phonegap.plugins.barcodescanner.ENCODE"/>
<category android:name="android.intent.category.DEFAULT"/>
</intent-filter>
</activity>
So, anyone any ideas, why I'm not able to include the CaptureActivity?
You should ensure:
The ZXing Library is Added to your libs directory
Import the ZXing library in the properties/Build path
Ensure -- and this is the important part -- in the tab "Order and Export" that the Android Private Libraries is activated.
Normally, with the last Eclipse Android Plugins all this proccess is automatic when paste a jar inside the libs directory but there are some problems when add new libraries in old proyects. Try to enable the android private libraries.
ExtraBall: If you only want to capture barcodes you can try this fork of Zxing with the only indispensable of ZXing http://code.google.com/p/android-zxinglib/
ISSUE SOLVED
Well... Stupid mistake. In the end I realized, that I didn't need to include the XZing Library jar. The guy who started the project included the PhoneGap Barcode Scanner Plugin which can be found here. Followed the instructions and everything is working well...

I recently moved to MoPub and it all appears to be working well except for I have started getting this exception saying that com.millennialmedia.android.VideoPlayer can not be found. I looked and it isn't on the Millennial jar (I just got the latest from their site). Also my AndroidManifest mentions that class and Android Studio also says it can't be found.
This is what I have there:
<activity android:name="com.millennialmedia.android.MMActivity" android:theme="#android:style/Theme.Translucent.NoTitleBar" android:configChanges="keyboardHidden|orientation|keyboard" />
<activity android:name="com.millennialmedia.android.VideoPlayer" android:configChanges="keyboardHidden|orientation|keyboard" />
On Android Studio the VideoPlayer part is red.
This is the exception I got:

Looking at the latest Millennial Media documentation, it looks like
com.millennialmedia.android.VideoPlayer
isn't included. This may be an update that needs to be made.

I've posted this question on the Amazon Developer Forum and haven't received an answer in 4 days, I've also sent it to Amazon developer support and haven't received an answer in the same time frame, so I'm here, hoping someone can help.
I'm trying to add 'mobile ads' to a new application. I'm working with Eclipse - Helios
In my manifest I have the correct permissions set
I have the Libraries set, I've checked the build path and project properties and things seem fine, The project builds with no issues
In my code
I have inserted the Application Key
I have inserted AdRegistration.enableLogging(true);
I have inserted AdRegistration.enableTesting(true);
When I use 'Run As - Android App' the app crashes with this and select either of my normal testing devices (Kindle Fire or Samsung Galaxy Tab), it builds find and begins to load the apk unto the the device and then this:

Any help would be greatly appreciated
Rather than continue to wait for Amazon or beat my head over the issue I simply switched over to Google MobAds, so my manifest is now what Google requires. Thanks anyway.
I'm Naive in Android development. I tried to use flow/mortar for development and stuck with an exception.
Here's what I did. In Eclipse, I chose New (Crtl N) -> Android Project from existing code and imported the flow sample downloaded from the square flow website https://github.com/square/flow/.
Eclipse marked errors in all the files as the package name was not matching the file's location. So to fix the package mismatch issue, I moved the files from : \flow-master\flow-sample\src\main\java\com\example\flow to : \flow-master\flow-sample\src\com\example\flow.
After this, I got some more errors saying 'Unresolved to a Type' which I fixed by importing proper jar files. Now all the errors are cleared and I tried to install and launch the app.
The app crashes as soon as we launch with the Logcat error below:
E/AndroidRuntime(5438): FATAL EXCEPTION: main

Any suggestions for resolving this problem, I could not reproduce this problem on my device.
On devices with which android version program works and where it doesn't work? I am not sure if this is the case but you probably get this error on older devices, is that right? You should make sure that all the functionality of your program is available on older systems. Use your manifest file:
<uses-sdk android:minSdkVersion="integer"
android:targetSdkVersion="integer"
android:maxSdkVersion="integer" />
to define minimum sdk version, and you will get errors in your code if you are trying to use features that are not available on the device that you target.

There are no errors during build. I have recreated a fresh project, clean+build also, still the issue persists.
I am using Eclipse IDE with Android 4.0 Emulator. Issue stays with any emulator or real device.

I faced this issue Right after GOOGLE IO 2013
when i updated my ADT plugin, Android SDK tools to Revision 22
and Android SDK platform-tools to revision 17
All of my projects that previously worked started throwing ClassNotFoundException after the update for no reason.
Then i noticed that there is a new Android Package named as Android Private Libraries and after hours of trying i found a way to fix this.
Right Click on your Project then
Goto Build Path-> Configure Build Path -> Order and Export
when you are there you should check the Android Private Libraries and then click OK.
if you still face the problem delete all the files inside your bin folder and rebuilt you project.
Hope this solves your issue
To make sure your jar is actually exported at build, you should either:
put it in the libs folder
or fill the checkbox corresponding to your jar in project properties > Java build path > Order and export tab
If you are using some external libraries, except linking it inside Eclipse, don't forget to put them in "libs" folder in the application. It should be near /src, /res and etc. Just /libs/yourLibrary.jar.
It will tell the compiler(not exactly) to include this library to your APK.
Actually, the library I am importing is also an Android project and I have defined it as a library. In other projects, it is working the same way.
My manifest is as under:
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.basicgl10test"
android:versionCode="1"
android:versionName="1.0" >
<uses-sdk
android:minSdkVersion="8"
android:targetSdkVersion="15" />
<application
android:icon="#drawable/ic_launcher"
android:label="#string/app_name"
android:theme="#style/AppTheme" >
<activity
android:name=".MainActivity"
android:label="#string/title_activity_main" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
<!-- Only Single Touch and OpenGLES less than 2.0 versions used by default -->
<!-- We will use both multi and single touch handlers by using a class based SDK Version qualifier -->
<uses-permission android:name="android.permission.WAKE_LOCK"/>
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
</manifest>
I have the same issue.
What I've done is:
Configure Build Path.
Choose Order and Export Tab,
Select all the listed path or JAR file.
And Try it!
Good Luck.
