Android : Arbitrarily Load Resources At Runtime In Droid?

Mar 7, 2010

I've got some XML resources in my Android app. Each one has a different name like "bicycle.xml" and "car.xml". I'd like to know if there's a way to load resources based on conditions during run time.

As an example...
Say I had a text input in my app. When the user enters "bicycle", my app can look up an XML resource by that name, parse and load it. Whereas if they enter "car", they would end up with the data from the other XML file.

I've noticed so far that to load resources, you have to use the autogenerated "R" class, which restricts you to hard-coding resources at compile time.

Android :: Possible To Load A Layout XML At Runtime And Load Into Activity?

Sep 4, 2010

Is it possible to load a layout XML at runtime and load into activity?

In my app, I have various types of data like Person, Company, City, etc; The requirement is to dynamically load the layout, find views by tags (property names like Person.name, Person.address) and then fill in data. For example, if user has selected an object of type Company, we want to load a company.xml layout, inflate it and then associate various properties (company name, company slogan, city, address, revenue) to tagged views. One possibility I see here is - each view in the layout will be associated with property-name as tag and then appropriate data will be loaded in appropriate views.

What should be the best design you would recommend?

Android : Load Layout Dynamically At Runtime In Droid?

Nov 20, 2010

My application requires 2 screens and for this I have created two different XML layout files using RelativeLayout. One layout file loads whenever I run my Activity. Now I want to load the second layout on to the same Activity , when user click on a button in OptionsMenu and also when user press Back button the first screen loads instead of exiting the application. So that i don't need to create another Intent in my application.

Android :: Can I Load Resources From Another App

Nov 8, 2010

I'm developing an Android app for which we will be selling separate content in the Android Market. Since Android lacks an in-app purchasing model as iOS has, I have come to understand that this is the ideal way of selling additional content (but NOT functionality) for Android apps.

So the question is, how do I actually load raw resources from other Android apps, assuming that I know the exact name of the resource, app ID, etc.?

Android :: VerifyError - Arbitrarily Rejecting Large Method

Oct 13, 2010

I'm working on an android application for the analysis of measurements (e.g, blood pressure) using a Bayesian network model (PEModelOR is the class in my android application), which is embedded in a smart phone. Since the measurements are to be taken at sequential times, the model contains a number of variables referring to different time controls. With the initial version with 2 controls the model run without a problem but when I extended the model to 4 controls it crashed producing the following error:

CODE:.......

I saw that in a recent discussion http://groups.google.com/group/android-developers/browse_thread/threa... Dirk has encountered the same problem but unfortunately I could not see any solution to that. The extended PEModelOR method runs without problems in Java but it fails in the android application due to the dalvikvm verifier as far as I understood. The PEModelOR method is a description of a Bayesian Network in java and it simply contains definition of 62 variables and 62 probability distribution tables (in total 700 lines and the java file is 41 KB); below is a sample of the code (note that BayesNet is a class loaded via external jar):

CODE:......

Does the size/definition of PEModelOR cause the problem? I'm not sure how I can split it as it needs to be loaded at once for creating the network and running the model with available measurements. The thing is that this is even not the final version of the model, where the goal is to have 11 time controls, ending up with 112 variables and probability tables, and 1245 lines.

Is there a way out or alternative of implementing PEModelOR so that it does not fail at verification?

Android :: Runtime Error Using Exported - Signed Apk But No Runtime Error Using Eclipse IDE

Mar 2, 2009

1) I am developing my app in Eclipse 3.4.1 with Android (ver 1.1_r1) plugin. My app compiles and executes without errors when using the Eclipse IDE.

However, when I export my app (unsigned) using Eclipse (via {select project} >right-click>Android tools>export unsigned application package), sign it, and try to run it on the Emulator, it throws a runtime error when I try to update my sqlite database, at which time the specific error created is: SQLite error#14, unable to open database. It is able to read from the database without problems. (I have also verified that the database is: open, is not readonly, is not locked by another thread, is not in the middle of a transaction.)

I have limited experience, but this seems more like a "system" problem given that the app works OK in Eclipse IDE but then fails as an exported/signed apk. Some googling of SQLite resources revealed a similar error on a non-Android platform which was fixed by: "Set your permissions correctly on /var/tmp, or whatever directory you are using to hold temporary files".

Does Android have temporary files, and if so how does it handle permissions on temporary files? Is there a way to check or set these permissions to see if this fixes my problem here?

2) Not sure if it is related, but after I have run the exported/signed app which causes the runtime error, if I reboot the Emulator, and try to run the program using the Eclipse IDE , the program fails with the same exact error. PLUS I also noticed the following error message while the program is installing/running: 03-01 22:22:29.282: ERROR/PackageManager(53): Package com.northwestradiology has mismatched uid: 0 on disk, 10019 in settings; read messages:

I can restore the Eclipse version of my program to be able to execute without runtime errors by utilizing the -wipe-data option for the emulator. But note that if I run my signed APK using an emulator created with the -wipe-data option, it still throws the runtime error listed above...

Android :: Android - Retrieving All Drawable Resources From Resources Object

Jul 11, 2010

In my Android project, I want to loop through the entire collection of Drawable resources. Normally, you can only retrieve a specific resource via its ID using something like:

InputStream is = Resources.getSystem().openRawResource(resourceId)

However, I want to get all Drawable resources where I won't know their ID's beforehand. Is there a collection I can loop through or perhaps a way to get the list of resource ID's given the resources in my project?

Or, is there a way for me in Java to extract all property values from the R.drawable static class?

Android : Swap LinearLayouts From XML During Runtime (droid)?

Feb 19, 2010

I am trying to create an option in my code to change layouts using preferences. I already have the two layouts created in XML, but I can't figure out how to swap between the two during runtime. I would like to cause it to check during onResume() since it is called directly after returning from the Preferences screen and when starting up, however I can't figure out the code necessary. I tried just using setContentView() a second time, but it didn't seem to work. What can I do?

Android :: Get Short Array From Resources On Droid?

Apr 10, 2009

I've got an XML file storing an array of shorts in my resources. I need to assign this array, but Android API only provides a way to get array of ints (getResources.getIntArray()). I've ended up getting an array of ints and converting it to array of shorts later, but that's hardly ideal.

Is there a way to get an array of shorts from Android resources? If not, is there a more efficient/cleaner way of converting int array into short array? My code ...

Sep 23, 2009

I am writing an widget application for android.

I have a requirement where i need to disable the widget on some intent, i.e., I have the remove the widget from the android home screen and remove from menu options so that the user cannot add the widget further.

I have to enable the widget on some intent, so that, the framework automatically adds the widget to the home screen, by calculating the empty position available on the home screen, and the many option re-appears in order to add the widget further.

Please let me know if this can be possible..

Android :: DVM Instance Creation - Launch Installed Droid App At Runtime From Another?

Oct 14, 2009

I trying to understand how a new process is being created based on AndroidManifest.xml, also looking for the possibility of creating/ forking a new Java process/new DVM instance at runtime.

I could find that using Runtime.exec one can issue system commands or launch native applications, but this is not what I am looking for, I am looking for creating an equivalent java process just as the parent java process.

Can I launch an installed android application at runtime from another android application? Whats the way for doing this?

Android :: Load Single App During Load And Not Allowing The User To Step Out Of It

Oct 22, 2010

I have been assigned the task to use an android tablet to run a single app in an enterprise setting. Ideally, when one switches on the tablet this app should be loaded perhaps during startup and the user need not step out of this app. The app logic itself is rather easy but I am wondering if it is at all possible to load a single app during load and not allowing the user to step out of it.

Android : Dynamically Load App List In Droid?

Aug 13, 2010

Be default, when the system is up, all apps will be shown in the home screen. Now if we provide a customized log in screen, user A log in, then for this user, he can only see (and use ) app1 and app2. Then A log out, user B log in, he can only see app3 and app4.

Does API provide such capability to load the app list dynamically?
