We are converting out suite of iPhone apps written in .NEt MonoTouch to Android.
How do we catch, then publish exceptions so that they are reported via the Android Market?

I read somewhere not to exception handle when developing in Android, is that true?
If one does need to exception handle are there any logging tools for 2.1 and above?
If shouldn't exception handle, why is it not recommended to at least use the below?
try {body-code} catch (exception-classname variable-name) {handler-code}
My application uses WebView to load javascript which calls into Java class (through webview javascript iterface). Can the JavaScript catch exceptions thrown from Java?

This code is straight out of the Android SDK development guide located here (http://developer.android.com/guide/topics/data/data-storage.html#filesInternal)

However, this code give me errors for the 3 lines of code at the bottom. The error is an unhanded exception. The suggested quick fix is do to the following:

But after doing that I get an error for the bottom two lines which states that fos may not be uninitialized. How can I fix this code? It's kind of annoying that the Android SDK gives you an example that doesn't even work.
I can't say I'm an expert at exception handling either.
I'm trying to catch a login exception thrown by the class that readerAccount belongs to in the code below.
CODE:......................
However, the only part of the catch statement that happens is is the Log.w() function. I was under the impression that during a catch statement, you have the opportunity to recover from errors, but the program blacks out the screen altogether and the dialog is not displayed, nor is the Toast.
I am using AsyncTask in my application.
The problem is that when server is down the AsyncTask throws an Interrupted exception. How to track that whether server is down or not.

This same problem also occurs when the handset is kept idle for some time then keyguard gets lock and I suppose that WI-FI also gets disabled. So, when I enable the keyguard and if my application is in foreground then it gives the same exception. What should I do in order to remove this exception?
This is the sequence part of this question: http://stackoverflow.com/questions/3674441/combining-2-images-overlayed
so the problem is: if the image size is too big - it'll got an exception (out of memory exception)
what i want is, to handle even if the handset got the lower spec hardware, it doesn't go to that exception (but it'll take a longer time to process the image) is it possible to do that?
The code snippet is like this:
CODE:......
And that block of code is inside the async task.
I have class A in which I have a method openfileConnec().
It was written like the below:
CODE:...............
Now I come to class B where I will call this method like the below:
CODE:.............
I was asked a question in an interview as follows:
Why does the method have a throws Exception in its declaration? Is it that on of the methods called in the implementation throws the base class exception? Also If we get a exception during calling the method (fileConnect( )) control goes to catch block. After executing catch where should the control go, what should be sent to base case?
This may sound like a weird question, but I have developed a mobile web application which works well with Android (browser). Would it be possible for me to somehow list this website/application on the marketplace? Or does it strictly have to be a downloadable app?

CODE:............
Everything was fine until I now implemented Threads where Exceptions are being thrown and caught.
You probably already have seen, that I played with the Looper Class, but honestly I don't know how to make it work. Is that the right approach? You also can see that I already store a reference of the ApplicationContext in my Controller. Shall I do it with the ActivityContext as well and than make the Toast from this ActivityContext? (But I heard that this is not a good practice in terms of performance)
Update
Is this the way I should go, when an Exception is being caught in a Thread in an Activ ity?

I have some required try/catch statements in my application that in my testing never get called. I have sent them up with:
Log.e("messaage", e.toString());
For my debugging and now that I'm ready to release I am not sure if I should take that out or not. I see in android market you can get error/crash reports and while I do not expect my app to catch any errors, I would like to know if that happens and wondering if I need specific syntax for that. My question is what should I do in the catch statement for these errors? I'm already handling the error from a user standpoint...
I published an application that stores data in a local database.
Now I have to publish an update to this application to fix some little bugs, but I am afraid that downloading and installing the update will delate the local database associated with the previous version.
I would like to know how the update system works. Will installing an update completely delete all the apk, files, databases associeted with the previous version?
If so, how can I avoid this in my code?
This is not a programming question per se but a question that may be relevant to all future Android developers.I am in the market for an Android developer phone. I can buy it used on eBay, or I can buy it new on the Android Market.All nice and dandy but in order what the Android market has to offer, I have to first register, which requires signing the Android Market Developer Distribution Agreement.Well, I know that many developers signed that agreement and stayed alive, but before signing anything I prefer to read what I am about to sign. Unfortunately, certain information that is needed to be understood in order to sign the agreement can be accessed only after you sign the agreement.For example, how do I know which are the "authorized payment processors" mentioned in clause 1.2?Also, it sounds strange to me that in order to just see what developer phones are available (and their specs) I first have to register and pay the $25 registration fee. It will take at least 6 months before I will be ready to place anything on the Android market, so why should I register now?

More importantly, how can I use the emulator to be sure that my changes will fix it?This user has a Motorola DROID phone, which has a different screen resolution and maybe other slight differences.I assume that the problem was I didn't test using the right screen size. However, I followed the instructions here and tested a larger screen and the text was fine. I know my app has fixed pixel heights like this: android:layout_height="64px" and I use text side parameters like: android:textSize="14sp" or android:textSize="12pt"

Went to install Need For Speed shift on my phone a few days ago, but it wouldn't install due to space. I went in and removed a few apps, one of which was my co pilot Sat Nav, which I think was 25mb alone. NFS still wouldn't install so I removed a few more apps. Suddenly my I got a message saying space on phone was low. This did not appear even before I removed apps including co pilot. When I check my memory it says there is 12mb free. It should be a lot more than that with copilot off the phone. So I should have a lot more free than that and should not be getting these messages. Is there any way to get the phone to recheck free space?

I'm just about done with development and emulator testing and I'm unclear how to proceed with getting my application ready for actual device testing and them publishing.
Here's my main concern: I have around 600 images that I will need to have loaded (on initial installation) onto an sd card. What is the best way to do this? HTTP? Is there an automated process? Is this handled by an installation script.
Are there documents that cover this type of scenario?
When it comes time for actual publishing the application, again, how will I handle loading the images onto the sd card during the initial installation?
In terms of publishing apps for developers that reside in countries where they are not currently able to sell their apps via the Android Market, is this practice okay? Does it violate the Terms and Conditions of being a seller in any way?
View 4 Replies View RelatedI am working on an app that uses the rating bar (stars) to allow the user to grade information. The SDK version is 3 (OS 1.5 - <uses-sdk android:minSdkVersion="3">, but the rating stars are shown incorrectly for devices with OS 2.1. I read some posts in the forum that suggest to upgrade the SDK version to 4 (OS 1.6 and higher), however this will excluse 1.5 users to download my application, and I do not want this to happen, because there are still a lot of 1.5 devices.
This makes me wonder: Is it possible to publish two versions for the same app simultaneously? For instance, publishing one APK for version 1.6 or higher version and another APK for 1.5 version simulataneously in the Market, both intended for the same application.
Is there a workaround for these kind of situations?

I'm just about ready to Publish my application. I have a question about the Signing/Aligning of the application. In looking at the Android documentation they say to run "ant release" to compile the application in release mode. Then to sign and align the apk run "jarsigner" and "zipalign". I had used "android create project" to create my build.xml.
I modified it to run proguard. I find that when I run "ant release" it appears that signing is done as part of the process (I'm prompted for my keystore password) and the apk is zipaligned. I guess I'm confused that the documentation makes it 3 steps, "run ant release" then jarsign, then zipalign. BUT, my "ant release" seems to do everything. Is the documentation not upto date? Is it safe/acceptable to just run "ant release"?
