I have created a multithreaded application but it still hangs if the server is unavailable.causes some delay and I believe this is the cause for hanging. But if the TCPClientService Service is executing in its own thread I don't know why this affects the timeout of the main activity.I would be very thankful if anyone could show how to prevent the application from hanging when the server is unavailable.

I was wondering what the most effective way of preventing people from stealing my application (downloading a copy of the .apk online rather than buying it).I've spent a lot of time on one in particular (Droidbox) and won't be releasing Sync until I can guarantee that the people who are providing illegal copies of the pro version aren't able to.Anyone implemented this? I've tried checking my package signature verses an the signature of an unsigned copy but it appears to be the same - perhaps I'm doing something incorrectly here. I'm unsure whether people actually distribute the signed .apk in which case I don't think signature validation would work to begin with.Please note, this question is specific to Android Marketplace Applications - the difference being, application delivery is out of my hands and I have no way of linking between a legitimate purchase and an illegal download.

My application has an emergency button which dials 911 when clicked on. Every thing on the app is working fine. But I just discovered that whenever I try to add another call when I am in a call, it promps me to complete the action using. 1. my app 2. The normal phone And when I click on my app, it just opens my app. I do not understand what is causing this and do not want my app to be shown in that list.

i have a android application which is ready to release .so to release i have put the app in android market .the user can buy the app and can install the app into the phone.android market wont provide any apk file to the user .so normally we need not bother about re distribution of of the app to the unauthorized persons(who didn't buy the app). But what my problem is ,I heard that there is a jail breaking concept which can allow the hacker to get the apk file(installation file) from the device .(even though android market not giving the apk file to the user ).then he can distribute the apk file to all(to unauthorized persons ).how to avoid it.is there any thing to restrict the unauthorized person in using our app,even though he get the apk file . does android market provides the details of the users who has buy the app by paying?

Quote from the Market upload page: "(Helps prevent copying of this application from the device. Increases the amount of memory required by users to install the application)"

Hello, I would like to create a zip file from files located on the sd card, I have managed to do that using java but I think that the result is too slow, so I thought of going native using the android NDK.
My questions are:
Does anyone know any C/C++ library to zip unzip files that will work on android?
How to know if the library will work on android?
will this make any difference on performance?

A Galaxy user emailed us to report that one of our apps crashes when he performs a function, we had over 10k downloads of this app with no similar report. Since the Galaxy is not yet available in the US, is there a simulator to help resolve issues like this?

I have a native application that I would like to start from a Java interface. Does anyone know of a good way of doing this? can start the application using adb, with no problems. I can also start the application using Runtime.exec(), but that doesn't work so well for me; I need the application to run outside of a Java Runtime Process. Any ideas?

We want to migrate a huge complex native program to Android system ,running it as a background service accepting command sent from Java Program using JNI along with IPC. However, the Android NDK state following words:
Please note that the NDK does not enable you to develop native-only applications. Android's primary runtime remains the Dalvik virtual machine.
Does that mean we have no way to run an standalone native-only application on Android as a background service? The native code can only exist in the form of library that will be loaded to the virtual machine through JNI?

I'm using Google Code to host my application code, its convenient and the SVN repository means I don't have to worry about backups. When you create a project on there you need to select a license, I chose GNU GPL v3. By doing so, does that prevent me from selling my application on the Android market place?

I tend to believe that developing mobile applications in an enterprise environment is best suited by developing intranet web applications. That said I have been asked to think about whether there are specific enterprise applications that could only be accomplished or would be more successful as native applications. I am curious as to what the Stack Overflow community thinks.

I have developed bluetooth application where native library will be initiated by Java application (using JNI wrapper). JNI will call the entry function of the native library and then it will create Pthread to for scanning the device. Once Scanning is over, i will get the callback which i registered during the entry function of the native lib (called by app). But i haven't received the callback, but if i run the same native library in the shell (executable from the shell terminal) it is working fine. Can any one help me, if there is any specific architecture needs to follow while developing Java application based on native lib?

I am trying to run a native executable from inside an android java application. The native executable exists in my assets. At start of activity, I copy it from assets to my application cache Dir. then I use Process Builder to run it.I tried to run "chmod 777" on the file and on cache directory containing it and I ensured permissions are granted using adb shell. but I still get this permission exception.

I'm trying to follow the example from google: http://code.google.com/apis/maps/articles/android_v3.html
Using the example files from their SVN repo: (http)gmaps-samples.googlecode.com/svn/trunk/articles-android-webmap/
But although it seems to compile and export it fails; can someone sanity check that its not just me this fails for and any hints as to if its a quick thing to fix, I've been prodding it with try/catch for the last 2 hours to no avail.
Forgot to add
It Compiles and Uploads to the emulator (and to my phone) but running it just results in
The Application WebMapActivity (process com.google.android.examples.webmap) has stopped unexpectedly. Please try again. [Force Close]

I've talked to a lot of people recently who say they are expecting to stop writing native mobile apps and start writing web apps once HTML5 gets more fully baked in mobile OSs. I just finished my first HTML5 deep dive, and I'm not yet convinced.
Will HTML5 work as a replacement development platform for native apps, or are there certain things that require targeting the native runtime?

wanted to add a menu option in native email app in android . I have used intent filters but i am not successful in achieving it. Actuaaly i want to a menu option to the native mail application in Android.. so that my activity / app can be launced on clicking that option. This feature has been successfully achieved in Blackberry and even in android for gallery application. On android i have achieved it by using intent filters.
<activity android:name=".DisplayAlternativeMenu"
android:theme="@android:style/Theme.NoTitleBar">
<intent-filter android:label="My Activity">[code]....
This basically display an menu item"My Activity" when u press share in Gallery. and clicking on that launches my activity .But unfortunately it didn't work for Email Application. Looks like the pair of action & mimetype i am specifying is not correct. which action & which mimetype should be used. Also if there are any permission required,what are they?
My aim is to add an alternative menu while pressing menu in Compose Email(When a mail is composed) of the native email application

This is what I'm trying to support. Can this be done?
a) User is an Activity A in my app. b) The user is taken to the native dialer when he chooses a particular action in my Activity c) User presses the back key d) Taken to homescreen
Is there a way I can change it, so the back key press returns him to my app, instead of native homescreen?

I am facing in Android display system(Video Rendering using Surface Flinger Native APIs).
As for my understanding, Android display system relies on Surfaceflinger library( a system wide screen composer). Surfaceflinger runs as a service along with Mediaserver service, Camera service, Audioflinger and these services interact with each other through Binder APIs at native level. If any user application wants to access SurfaceFlinger native APIs, it requires Surfaceflinger Access permissions.
My requirement is that I want to create a SurfaceView at the JAVA level (Android Application level) and render video data to that Surface, means, pass video data to the Surface flinger library by invoking native Surface Flinger APIs. But, because of Permission Problems, I am not able to invoke Native Surface Flinger APIs from Application Layer.
Is there any ways to invoke Surface Flinger Native APIs from Application Level ?
