[android-beginners] Re: Android communication
Or to put it another way, the current method is to use a make a server somewhere on the internet (or perhaps wifi intranet) to catalog and function as an intermediary between the phones. In the future or maybe now with low-level hacking, ad-hoc wifi or something bluetooth based could become an option.

[android-beginners] Re: Compile C on Android Phone
On Oct 3, 5:18 am, Sean Hodges seanhodge...@googlemail.com wrote: As far as I'm aware, no. There is no native C compiler available for the stock Android platform. To get that level of access to your device, you'd need to root the phone and cross-compile a tool-chain for it. Rooting the phone is not technically required, though it would make life easier by opening up your options for where to install the executable. I'm not aware of a C compile that has been made to run on an android phone (as opposed to produce executables for one, which is common). I'm sure it is possible, however I would also suggest that it's probably not a good idea - you have a computer with limited ram, the available storage media is not really designed for intensive re-write cycles, and you don't exactly have a great platform on which to do serious file editing. But none of these things mean you couldn't do a little light duty development on the phone if you really, really want to. If you really want to do it, an option to compiling a compiler with the android toolchain would be to see if you could make one built to run on arm-linux work by moving over enough of the arm-linux shared libraries, as this may be simpler than trying to compile against android's non-linux libraries. Look up the people who have been running Debian-arm on (rooted) phones. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Android Beginners group.

[android-beginners] Re: Unable to compile C application in Emulator

That is not the right toolchain to be using for Android, as while Android has a linux kernel it does not have a usual linux userspace or libraries. If you can statically link the executable and it's in the right format it might work, but Android is primarily intended for pseudo-java programming within it's provided SDK. If you really want to write (or port) C programs, download the android NDK and re purpose its toolchain to build executables dynamically linked against Android's unique runtime libraries. That toolchain is actually intended for building jni libraries, not stand alone executables, but if you search for an unofficial setup called android-ndk-wrappers you will be able to set it up for somewhat normal compiler usage. Also your executable will have to be stored somewhere that is not mounted noexec, and have its exec bit set. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Android Beginners group.

[android-beginners] Re: How Can I Block Unwanted Calls.
But there's no reason a future version of the platform couldn't include both a documented api and an explicit reject calls permission.

After all, malware might exploit this capability to block all incoming calls, or random incoming calls, or something. Malware with the permission to block calls would also have the permission to make calls, wouldn't it? If so, would think that be more serious, potentially running up substantial bills - and point to the same caution of users needing to be careful of what applications with phone permissions they install. I would think that the ability to block calls, for example all calls not in contacts, is much more likely to be employed to combat malware of the robo-dialer sort used by unscrupulous telemarketers... --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Android Beginners group.

On Sep 9, 4:30 pm, Earl Wilson earl...@gmail.com wrote: No you can not. The type of applications you can develop on a windows mobile device is windows mobile applications. Android is different the windows. That is the same as trying to run or develop Mac OSX apps for your windows phone. What keeps you from developing OSX applications for windows is not primarily something technical, but Apple's perhaps over-reaching claims of control over the OSX api's. In the case of android, the apis are not only documented but the actual code is available (and if you are careful to do it right, legal) to use as the basis of a translation layer. In other words, for running android apps on a windows mobile phone the problems are simply technical... if someone wants to do it badly enough, they will come up with a way to. More practical and popular approaches seem to be to try to get a build of android running entirely in place of windows mobile. The HTC line of android phones at least give the impression of being descended from from the hardware of their windows mobile platforms. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Android Beginners group.

No. That is the equivalent of asking if you can develop windows applications to run on Linux. Well, I do that routinely (specifically, I write windows applications by cross compiling from a linux machine, and test them on the development machine using the wine compatibility layer). I would assume that sooner or later we are going to start to see compatibility layers to allow applications developed for one framework to run on another, though it may not become fully practical until phones have a bit more horsepower, and it will probably first become practical as a cross platform toolkit where you write for the compatibility layer rather than any native framework. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Android Beginners group.

Just to expand on what others have said: Cost seems comparable betwen a dev phone and a retail phone at full retail or plan price + termination fee, so it's really more a of a technical question. Reasons for a dev phone -sim unlocked (some such as tmobile may? do that if you pay full retail or eventually on a plan) -can change linux and system libraries -can change pre-installed applications -tmobile myfaves application sends periodic sms which costs money on any other network Reasons for _not_ getting a dev phone -only one older dev phone model generally available at present -dev phones can't buy paid applications from the market (including your own) -if you sell apps, you need to restrict yourself to the capabilities of your users phones (and test on such a device!) -various preinstalled proprietary applications missing (+/- depending on your interest) The not being able to change preinstalled applications is in my mind the least anticipated, and most annoying, problem. There are many areas where very small decisions of questionable wisdom in default applications really hamper the user experience (even in the using it just to make calls sense), but these can't be very readily changed on a retail phone, particularly the parts most closely involved in the telephone functionality. As of this moment, I believe most of the retail phones are probably still shipping with an easily rooted linux kernel, but that probably will get closed up (already fixed in google's tree) and they will be limited until another hole is found. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Android Beginners group.
