I have a library-only Android eclipse project (no main class, only library classes) that I want to include in my main Android Application project. I went to the Build Path and added the library project to the "Required projects on the build path" on the Projects tab, and checked it on the "Order and Export" tab. However, when the application is run, it emits VerifyError exception, because the class from the library project didn't happen to be packaged together in the apk.

View 2 Replies View RelatedIn my Android app, I always get VerifyErrors! And I cannot figure out why. Whenever I include a external JAR, I always get VerifyErrors when I try to launch my app (except for once, when I included Apache Log4j.) I usually get around this by taking the source of the library and adding it to my project, but I am trying to put the GData client library (http://code.google.com/p/gdata-java-client/). I can get this in source, but it's dependencies (mail.jar, activation.jar, servlet-api.jar) I cannot, so I get verify errors. I would like to get to the root of this problem once and for all. I looked on the internet, but they all seem to talk about incomplete class files? which I do not know of.

View 2 Replies View Relatedi'm trying to include a maven java project into my android project. the maven project is the greader-unofficial project which allows developers access to google reader accounts, and handles all of the http transactions and URI/URL building, making grabbing feeds and items from google reader transparent to the developer. the project is available here:
the code is originally written for the standard jdk and uses classes from java.net that are not a part of the standard Android SDK. i actually tried to manually resolve all dependencies and ran into a problem when i got as far as including com.sun.syndication pieces required by the class be.lechtitseb.google.reader.api.util.AtomUtil.java... some of the classes in java.net that are in the standard jdk (i'm using 1.6) are not in the Android SDK. in addition, resolving all of these dependencies manually is just ridiculous when i'm compiling a maven project that should be pretty simple.
however, i can use maven to compile the sources with no issue. how can i include this maven project, which is dependent on the complete jdk, into my android project in such a way that it will compile so that i can access the GoogleReader class from my android project? and for the record, i don't have the expertise to rewrite this entire api to work with the standard Android SDK.
The app I'm working on has 4 tabs, 3 of which share many features, including a navigation bar a the bottom with Back, Edit, and Map buttons. There is exactly the same xml in all 3 layouts, so I'm trying to DRY this out by extracting that xml into a separate component, including it, and then going from there. Previously I had:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_height="fill_parent"
android:layout_width="fill_parent">
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/showedit_toolbar" style="@style/showItemToolbar">
<ImageButton android:id="@+id/show_person_back_button"
style="@style/blackToolbarButton"
android:src="@drawable/left_white_arrow"
android:layout_alignParentLeft="true"/>
<Button android:id="@+id/show_person_map_button"
style="@style/blackToolbarButton"
android:text="map" android:layout_alignParentRight="true"/>
<Button android:id="@+id/show_person_edit_button"
style="@style/blackToolbarButton"
android:text="edit" android:layout_toLeftOf="@id/show_person_map_button"/>
</RelativeLayout>
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_height="fill_parent"
android:layout_width="fill_parent"
android:layout_above="@id/showedit_toolbar"
style="@style/CoinLightTheme">
// Lots more layout omitted
I extracted out the bit that's repeated into an xml file called show_toolbar.xml, changing the names of variables to make it more generic across the 3 views
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/show_toolbar" style="@style/showItemToolbar">
<ImageButton style="@style/blackToolbarButton"
android:src="@drawable/left_white_arrow"
android:layout_alignParentLeft="true"
android:id="@+id/show_back_button"/>
<Button android:id="@+id/show_map_button"
style="@style/blackToolbarButton"
android:text="map" android:layout_alignParentRight="true"/>
<Button android:id="@+id/show_edit_button" style="@style/blackToolbarButton"
android:text="edit" android:layout_toLeftOf="@id/show_map_button"/>
</RelativeLayout>
Then from within my original layout file, I replaced that big block of code with
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_height="fill_parent" android:layout_width="fill_parent">
<include android:id="@+id/show_toolbar" layout="@layout/show_toolbar"/>
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_height="fill_parent" android:layout_width="fill_parent"
android:layout_above="@id/showedit_toolbar" style="@style/CoinLightTheme">
Now, the problem is that the view no longer shows up. Including Custom component causes it to be hidden behind main viewI can still click the buttons and they respond (i.e. if I click in the corner where the button should be, it still works), but I cannot see the buttons or bar onto which they were drawn. I cannot find very good documentation on how Include is supposed to work, so perhaps I am using it incorrectly.
I picked up a Zeki TB782B for my kids to use and I have been really happy with it as an entertainment tablet. I have put my daughters gmail account into it and gmail works great, but contacts app does not show up anywhere including apps. It is on the tablet as a native app, Titanium is backing it up and it seems like it should be running. I rolled back the system updates to the app and still nothing.

So, my questions:
a. What is/are the files that are downloaded?

c. What happens during installation? Is there just one binary? Or a binary with lots of other files? How can I find out the files that belong to a particular application.

View 49 Replies View RelatedWhat will be the best storage choice for an application with huge amount of mb in media? The application will not be in android market.
First choice was to use assets/ folder. At least, 160MB of audio is shipped with the application. When I moved all the media to the assets/ folder, I end up with:
"Conversion to Dalvik format failed: Unable to execute dex: null"
And reading: http://code.google.com/p/android/issues/detail?id=2328 suggest me that maybe it's not such a good idea to ship all the media in an .apk file. I think that the problem has nothing to do with large .java files, as it arises when I copy the bunch of audio to assets/.
I was thinking in using the sd card storage. But, I don't want the user to accidentally remove the media files. I want it to be private, not accesible to possible deletions. So, another approach is to use the private storage and download the media in the application first run, or something like that.
I've created an application which uses around 15 small audio files. Right now I'm using mp3 files and each is around 200KB. These files are stored in my res/raw directory. I'm using SoundPool class to play the files in my application. I'm hoping to put this application on the android market place. Can one of you suggest what is the best way to store so many audio files? Will my application be scalable? Is wav or ogg format better approach instead of mp3? Please let me know.

View 2 Replies View RelatedI m designing a big android application, where there are XMLs to store temporary data, images captured by camera and other details.

Is there any alternative way, something at folder level ?

I am working on an android app that needs to act on a few data files totaling around 30MB. I put together a test and the emulator failed with OutOfDiskSpace. Debugging on a device failed with even a smaller data size. After reading through the google groups, it appears that the application size limit isn't stated anywhere and nobody from google has been forthcoming with specifics about this. Given that there are iPhone apps that are over 100MB in size, putting such a small limit on Android apps seems weird, except just for the fact that you have a relatively small amount of total available app storage space (< 100MB).What techniques do you use to deal with this limit? If you have an app that needs more than 10MB, do you put it on a web server and deal with downloading it the first time? If so, how do you handle access control so that only your app can get the data?
