Okay here's the deal:
I want to download the full source of the MMS/SMS application that ships with Android phones. I want to be able to modify it, and add a little custom functionality to it.
I am developing using Eclipse, and I'm on Windows 7. I have noticed that there is now a Git for Windows, but I am pretty lost in it and not sure how to integrate everything with Eclipse.
Basically, I want to just get it to the point where I have all the source code visible in Eclipse and be able to see the app run JUST like the built-in texting/MMS app that is already on my phone. Then I'll know that I can modify it and proceed.
Any ideas?
Thanks!
There's a mirror of the SMS/MMS app on GitHub here. Just import that to Eclipse and customise away.
Unless you want to customize and use it only on your own phone (without publishing), this is not a good idea. This is because it uses classes that are hidden from the sdk. By default you won't even be able to build the apk via eclipse, but there is a way. The reason why this is a bad idea is that the hidden apis are not guaranteed to remain the same through different api-levels and your app can stop working with the next android update, and might also not work on previous api-levels. In-fact your app might not even work on selected phones running the same api-level.

Prerequisites: Got a working app from a friend who needs some changes made. They were outsourcing and now want to internally manage it.
I come from a web and game dev background, so Android/IOS development is new to me, but a lot of the principles seem to be the same.
I got the project onto my device, installed all of the dependencies, and fixed all of the file paths.
The app successfully builds, and I have my virtual Android device running it great!
However, my buddy wants some really simple layout changes, and for the life of me, I can't find where to just edit the home screen layout. I was trying to solve my issue from a web dev approach, by grepping where the logo screen is used in the app, but those files seem to just load a white "background" layer, and not the entire composed page?
I'm missing something really silly here, and I just want to ask a real person on here, instead of digging through documentation and trying to word a condensed question in a Google search.
Here are my condensed questions: How can I just edit the home screen of my app in Android Studio? Where can I find the full home page file to view the entire layout, and not just a fragment?
Edit: The app also utilizes the Flutter SDK, which may explain why I have been having trouble with layout edits. I'm going to look at it again after work today, and hopefully answer my own question. I appreciate the help so far!
Edit 2: After going back to the app with a different approach, I found out my project had defaulted to the "android" sub folder of my master, and wasn't showing any of the Flutter .dart documents. After going up one folder directory, I was finally able to access that Main.Dart file with the display information.
I was able to mount it for inspection, but its saying my emulated device isn't supported. I need to look at it when I have time tonight, and may need to ask a separate question for it. I have my project sdk set to Android 33, and my virtual device is set to Android version 33. I searched around Stack, with a few people with reporting similar issues. I tried following their solutions, but it didn't seem to work.
We have a custom ROM for a device we are making and what I want to do is make our own custom Settings app to replace the settings app that comes already built in android.
I cant really find any documentation on how to even create a system app. It does not appear you can create it in Android Studio, I tried looking on the AOSP site and didnt find anything there related to creating system apps. The few things I did find were on here where you would put android:sharedUserId="android.uid.system" in your manifest and then has to be signed with the same key as the ROM but after that I cant find anything.
The settings app I want to create would need access to the framework.jar to be able to use the hidden framework API's.
Does anyone have any information or know where I can find this information on how to go about actually creating a system app?
You may want to research how to make a Device Tree Overlay (dto). Basically it is your code, reformatting the base code, into what you want. https://source.android.com/devices/architecture/dto?hl=en
Since you said you use Gradle, you should put first build you apk and put them in you vender folder, and next important thing is to create a mk/bp file to tell the Android build system how to deal with this pre-built apk.
P.S. If you system app highly depends on Android hidden api, make sure you have the right version of framework.jar in you Android Studio project, or, as what I alway did, create apps directly in AOSP, in this case, you can just check the code structure of the original Settings app in AOSP

is it possible to create an Android 1.5.1 app using Android Studio?
Yes it is old but still used...
It only has to read 3 different txt files which are located on local network, containing 1 line of text each and display it under each other in portrait view.
Refresh ones a minute should be ok.
And it has to have a dropdown menu so you can choose which number of device it is, so from 1-10 is ok and according that read the txt files which belongs to that device nr.
I can't use a webpage because i cannot create a local server for it. So i need a little app.
To create the txt files i use a windows program.
I use Livecode (since short) but it can't create apps below Android froyo 2.2.
Any help on this would be highly appreciated. As i don't know anything about java.
It's only for local use, nothing commercial or anything
Thanks for any help on this!
You should try using PhoneGap (Cordova) http://phonegap.com which is basically a HTML-Webview, wrapped up in an App, so you can code the whole thing using JavaScript, and it is still a real app.
With this it should be very easy to do that, even if you "don't speak Java".
But to answer your initial question, yes it should be possible to create an Android App for 1.5.1 with Android Studio. You just need to install the right SDK/Packages etc with the SDK Manager.
Have fun coding.
i want to make an application or more like a tweak for android
i want to write some code that's gonna work on an android device and will do curtain actions based on an input from a Bluetooth device
this application needs to run in the background at all times (as if it was part of the device's operation system)
and be getting input every second
i need it to be able to bring up i custom keyboard i am gonna design and to set up a courser just like in a desktop which can be controlled by the application.
i read about something called a ROM and i dont know if thats what i am looking for.
i also know that the android operation system can be modified or replaced with another operation systems like the one called cyanogen .
i am a beginner and i have got some background in java
i tried creating an android app but i dont know how to make this thing work on the OS
i need someone to give me a very detailed explanation cause i know nothing about these stuff
It sound like your trying to make an App that takes Bluetooth input...
It doesn't sound like you need to edit the OS itself...
You need to set up the Android SDK to start development...
http://developer.android.com/sdk/installing/index.html
1. Download the SDK
2. Install the Eclipse Plugin
3. Write the code, and run it on the emulator or your connected device(make sure debugging is enabled under Setting->Applications->Developer)
Here's some info on getting started w/ Bluetooth...
http://developer.android.com/guide/topics/connectivity/bluetooth.html
Since you want this to run all the time, I would look into Android Services also...
http://developer.android.com/reference/android/app/Service.html
You may want to also take a look at the Sample Projects included w/ the SDK after you download the SDK and set up your IDE and Emulator(or phone)...
http://developer.android.com/tools/samples/index.html
Hope this helps clear some stuff up...
Is it possible to configure the Android OS to run only a single app?
Basically what I want to do is customize an Android device so that it boots up and runs one application only, and for that application to be switched to the front of the screen automatically. Also, when it gets closed, to be started up and switched to again. Any ideas?
Thanks,
-David
One method is to get the source of Android and write your own custom ROM of Android as Octavian wrote.
Another alternative would be to write a custom home app that, well, isn't really a home app (but replaces the default home app intent). See SlideScreen as an example of a non-traditional "home" app.
Yes it is possible. You have to fetch yourself the source codes for Android and basically create a custom ROM. After applying all desired modifications you bake your ROM and install it to your device.
Pretty much all you need to know about the source and the process of compiling the sources are located at Android Sources. You can view the source codes from your browser by following this link.
Hope it helps you a bit. Good luck.
