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?

Writing an app for Android Market that is written completely in C++ (a port of existing product actually).
Use fast screen-buffer pixel pushing (or rather using OpenGL ES for this).
Grab user input and direct it to C++ code.
Is it legal to write such an app for Market? Is Market policy somehow strict to such things?
I am making an android application that shows a list with users, I would like to add the image,name,status,and a button in every row of the list, just like in the androids 1.6 native caller-> favorites tab.Until know I have managed to add the image and name using an ListActivity but when I try to add the button the list becomes unselected.So I have 2 questions, first is the list mentioned above listviews or listactivities? also is this possible using listActivity? and second, what is the difference of the above mentioned classes?
View 1 Replies View RelatedIs it possible (without violating any licenses) to write a native C/C++ application on top of the Android OS and make it run as a daemon process?
There are already several daemon process' running which one can see with the 'ps' command, the legal part concerns me the most. And also the lack of documentation on how to exactly do this.
For the writing part, I guess one could use basic Linux programming concepts, since Android supports at least to some level the standard Posix API. To make it run as the phone boots, some modifications is of course required in init as well.
I have no plans to have this app in the Android Market, so installing it manually to the phone is not a problem. As long as it does not require re-compiling the whole OS or kernel.

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?
View 2 Replies View RelatedWe 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 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.
View 6 Replies View RelatedI 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'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

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 ?

OK I've been running the nightlys and they have been running fine except for the small issue that the native email app included in the ROM(s) never works. I'm trying to use my yahoo email account and when I open the app enter in my email and password I first get a prompt with: "Attention! Mailbox access is not supported for some types of Yahoo! mail accounts etc..."
Then I press OK and then get the initializing screen for "checking incoming server settings" then get a Could not finish prompt error stating that my user name or password is incorrect (which I know is correct and have tried numberous times)

I would like to change the Keep Alive Timeouts in the native SIP Application. I'm using a Nexus S with ICS. But I always get this error
Code:
I/ActivityManager( 152): START {act=android.intent.action.MAIN flg=0x4000000 cmp=com.android.phone/.CallFeaturesSetting} from pid 1745
E/MenuItemImpl( 1745): Can't find activity to handle intent; ignoring
E/MenuItemImpl( 1745): android.content.ActivityNotFoundException: Unable to find explicit activity class {com.android.phone/com.android.phone.CallFeaturesSetting};
have you declared this activity in your AndroidManifest.xml?
That's what i did:
-Check out Android Source with repo, Tag 4.0.3
-Edited frameworks/base/voip/java/com/android/server/sip/SipService.java
-lunch full-user
-make
-Copied the resulting Phone.apk and Phone.odex from out/target/product/generic/system/app/ to my Phone and fixed permissions.
