Android :: Is Binary Representation Of Native Types Guaranteed Same On All Targets?

Aug 5, 2010

I"m planning to store my data in a binary format as a resource, read it into an int buffer and basically pass it straight down to a native C++ function, which might cast it to a struct/class and work with it. No pointers, obviously, just ints and floats. The question is - what kind of fixing up do I need to do? I suppose that I need to check ByteOrder.nativeOrder(), figure out if it's big Indian or little Indian, and perform byte-swapping if need be. Other than that, floats are presumably guaranteed to be expected in IEEE 754 format? Are there any other caveats I'm completely overlooking here? (Also - since I'm compiling using the NDK, I know what architecture it is already (ARMv7-A, in my case), so can I technically skip the Indian shenanigans and just take the data the way it is?)

Android :: Different Versions Of Searchable.xml For Different Sdk Targets?

Nov 3, 2009

I have implemented a SearchManager which make uses of a searchable.xml with all the settings and put it in the xml/ directory.

I tried to create a new directory called xml_v4/ to add some attributes (the android:includeInGlobalSearch ie) which isn't supported in sdk3/1.5 but the xml directory seems not to be supported by the dir_suffixes.

How do I deal with this?

Android :: Is There Any Unicode Single Char Guaranteed To Be Available In All Appliances

Aug 27, 2010

In some cases I have messages, typically shown in a toast message, where there are three trailing periods. For instance, "bla bla bla. Please wait...". Note that this is _not_ an elipsis, as the string is not truncated. The problem is that sometimes the string is wrapped at the end of line and I get two periods in the first line, a newline, and then a single orphaned period in the next line.

I'd like to have the "..." not broken by any means. How can this be done in a reliable way? E.g. is there any Unicode single char guaranteed to be available in all Android appliances that gets rendered as three periods?

Android :: How Does PackageManager Detect What Architecture APK Targets?

Aug 11, 2010

i'm currently trying to specifically target ARMv7 custom hardware and I'm facing issues when trying to install the APK. When I try doing "adb install app.apk" Logcat informs me that: W/PackageManager( 1062): Native ABI mismatch from package file And does not install the APK. With searching I was able to trace down that the problem might have something to do with the architectures not matching on the APK and the platform. Is this it? How does the PackageManager find out the architecture from the APK file? I'm guessing it's not trying to execute the binary or anything, it just checks the files meta data? If so, is there a place in the APK where this information is located? Or am I completely hitting blank here and I should look somewhere else?

Android :: String Resource ID Values Guaranteed To Be Consistent Over Different Projects

Jun 7, 2010

I have some messages being passed back from my server through php. The problem is that the messages are in English and if the user is using another language they will still get the message in English.

So I had an idea that maybe instead of passing back the message I would instead pass the String resource Id from the android app, that way the app will get the correct string id for their language. I will use this in a number of apps so I just want to know if the string id is guaranteed to be the same across different android projects?

Android :: Is On Post Execute Guaranteed To Run After All Calls To Progress Update?

Jun 29, 2010

I would like to know if it is possible to get 'leftover' calls to AsyncTask#onProgressUpdate after AsyncTask#onPostExecute has been called? I am setting text on the same TextView using both of them, and I don't want to set text such as "Done!" and then have it overwritten at a later point by text such as "Almost there - 90%"Also, I am assuming that the onProgressUpdate method works similar to a SwingWorker method in that multiple calls to publishProgress may stack up before a call to onProgressUpdate occurs. I would really like to know where the "newer" and "older" progress updates are on the parameter - aka are the newest updates at position 0 in the parameter, or at position progress.length?

Android :: Multiple Versions Of Same Class File For Different SDK Targets?

Nov 5, 2009

This is for an Android application but I'm broadening the question to Java as I don't know how this is usually implemented. Assuming you have a project that targets a specific SDK version. A new release of the SDK is backward incompatible and requires changing three lines in one class. How is this managed in Java without duplicating any code(or by duplicating the least amount)?

I don't want to create two projects for only 3 lines that are different. What I'm trying to achieve in the end is a single executable that'll work for both versions. In C/C++, you'd have a #define based on the version. How do I achieve the same thing in Java?

Android :: Static Fields In Activity Classes Guaranteed To Outlive Create / Destroy Cycle?

Oct 28, 2009

I frequently run into the problem that I have to preserve state between several invocations of an activity (i.e. going through several onCreate()/onDelete() cycles). Unfortunately, Android's support for doing that is really poor. As an easy way to preserve state, I thought that since the class is only loaded once by the class loader, that it would be safe to store temporary data that's shared between several instances of an activity in a static Bundle field. However, occasionally, when instance A creates the static bundle and stores data in it, then gets destroyed, and instance B tries to read from it, the static field is suddenly NULL. Doesn't that mean that the class had been removed and reloaded by the classloader while the activity was going through a create/destroy cycle? How else could a static field suddenly become NULL when it was referencing an object before?

Android : ListView With Different Types Of Views?

Jul 2, 2009

I'm trying to make a ListView when every item in that list can be a different type of View. for example the list could be: 1. TextView 2. ImageView 3. MyCustomView

I understands that in order to make a list I need to use an Adapter. the problem is that the Adapter uses a single layout for all of the list items, which will not support the different views.

my goal is to make an abstract View list when I can dynamically add and removes items in that list (each item is a View or subclass of it).

Android : Use Each Of Droid's Different Messaging Types?

May 28, 2009

I've been working with Android for well over a year now, but I still have trouble determining when different types of messaging/communication between processes/threads should be used. I'm mainly talking about broadcasting Intents, using AIDL for services, using Handlers to send messages and socket communication.

Many of these tools can be used to accomplish similar tasks, but which is better suited to particular situations?

Android :: Can Pass Different Types Of Parameters To An AsyncTask

Oct 13, 2010

I want to implement a generic, thread save class which takes the RessourceId of an ImageView and the Url (http) where the desired image file is stored. It'll download the image and fills the src of the ImageView in the UiThread.

I thought AsyncTask would be the best thing for me. However I noticed that I only can pass one type of parameters to the doInBackground() Method. Like an Array of Urls. Is that true? What would u suggest me?

Android : Bluetooth Device Types / Can I Change It?

Anyone have any idea how I can change it? I've tried unpairing and repairing it like 3 times now...

I can't seem to find out how a MIME type is found. For instance, say I want my application to bring up Contacts. Where can I find the MIME type for that task? I currently have the following:

Intent intent = new Intent(); intent.setAction(Intent.ACTION_GET_CONTENT); intent.setType("*/*");

Intent newIntent = Intent.createChooser(intent, null); startActivityForResult( newIntent , SHOW_VERIFY_ACTIVITY );

And the wildcards work. But I would like to be more explicit. Like the following:

Android : Get Localized Label Of Phone Types?

Aug 24, 2010

When changing the custom locale the label of the phone types change to the appropriate language. Does anybody know how to get the localized label of the phone types?

I pick a contact in my app to get its phone number and if there is more then one number I use an AlertDialog to let the user select the currect one. In this pick list, I want to show the label of the type, so it's easier for the user to select. Since they labels are somewhere in the Android system, it must be possible to get the localized label. Unfortunately, the Phone.LABEL is null when reading the phone number.

// calculate viewID here
if (view == null || *view is not null but was created from different XML than viewID* ) {
view = mInflater.inflate(viewId, null);
