I am creating a game with some additional features, so I am using a normal JAVA development way and Unity for 3D graphics and the whole engine. These 2 parts are connected and both needed for the game.
The problem I am facing at the moment is how to combine them together so that user don't need to download 2 parts separately? Would much more convenient that download/install would happen together.
I have all the source files in Unity, but the only type I can export them is apk.
So I assume if there is a way to do, it should be done merging apks?
I dont think you can merge apk without creating one big apk by coding them again but you can make an apk and that apk will only download these 2 apk and then delete itself, or download these 2 apk into same folder
With than user will only download one apk and apks will contain in the same place.
If you still need it you can try that and let me know if my advice is helpfull :)

I have been searching a lot for the best practice for my problem and didn't find anything useful so far.
My problem is:
I have platform that create E-commerce apps for the user and than we publish it for the users on the play store.
NOTE: each app have different name and maybe different google account.
Every time there's bug fix or new feature, we need to copy paste the same code in every project and then upload them again to the store.
My question is:
Is there's smarter way to deal with this ? i mean what if we have 100 app of the same project, that will be pain to update the code in all of them and than upload all APK's again.
Maybe there's way to update the classes and content dynamic ? or even some tool that can organize the whole thing or manage uploading the APK's ?
Thanks in advance.
You don't need to copy paste the same code in every project and you don't even need different google account.There is a process called white labelling apps in which you can manage unlimited apk from a single project. Just add all the clients in product flavours in gradle file with different application id. Follow the link attached for detailed procedure of white labelling

Is there a way to get the source code from an APK file?

Closed 6 years ago.
My friend and I are building an android app for an FBLA State Leadership Conference Competition.
We used MockingBot to create a "blueprint" for our app, and planned on using Android Studio to replicate the design & make the app functional.
We downloaded the Android APK file from MockingBot. Instead of re-making it on Android Studio, is there a way that we can extract the Java & XML Files from the APK, and put them into Android Studio to complete most of the XML work, then tweak it from there?
THANKS
You'd normally be able to do something like this with a number of tools. apktool and dex2jar are good, jadx is a great all in one solution too. In this case, it looks like MockingBot uses Cordova to generate your app, meaning there is almost no real Java/Android code to decompile. It is essentially a web wrapper so you can build cross platform apps.
jadx will still allow you to extract everything from the application, but it might not be easy to reconstruct. I would suggest checking out Apache Cordova, or another project that implements it, such as Ionic if you intend on going this route. If you do, I also suggest using an IDE better for web developing. You can still use Android Studio, but vanilla Intellij might make your life a little easier.
Assuming MockingBot didn't use any Cordova plugins, you can simply unzip the APK and use what falls under the assets/www directory to start customizing your app using Cordova.
Edit: Because I can't comment without at least 50 points... This actually isn't a duplicate as was already suggested. The question might seem similar, but web wrapped applications are very different from those built using Java and much easier to decompile/reverse. The answer linked in your comments will very likely not help you.
Is it possible to run java app (jar) in my android application? Because I need to create PDF, the problem is if I generate PDF in android, only can show with small image, if it contains large image in many pages, it will be error. So I think, I can generate PDF in java and then included to android app.
Concernig the mentiones app JBED:
Well honestly, I could not find any credible source for this tools JBED, so I would really be very cautious (e.g. who is the developer?)
In the manifestfile (in Androidmanifest.xml, where every app has to state what rights it needs to run, see How to view AndroidManifest.xml from APK file?) there are many rights mentioned (what could be necessary, as the app wants to run as an emulator), so a java application might want to send an SMS, record audio, take pictures and place calls -- so the emulator would need those rights as well.
But then the app also registers the "android.intent.action.BOOT_COMPLETED" event (i.e. autostart after boot) and this would go against every description of the tool.
Ah yeah and giveaway: The apk has a folder "certs" that has some (root-)certificates. But those are not the real certificates of the authorities, e.g. Versign. If one installs the app and by that those certificates the trust you might have in https-connections is lost because those who made the fake certificates can create own, false certificates that your phone would trust.
I assume (or am pretty sure) this is a spy tool, but I could be wrong. The (rare) testimonials that claim the tool ran perfectly will probably be the same person that posted the tool under a different name.

You can import java Third-party libraries into Android app, follow the steps here.
I am not sure whether it will work,but just try.
If your program is a console program, the answer is yes.
Install Jvdroid from Google play. Click terminal and then write this command: java -jar YourJarFileName.jar
The simplest way would be to some install terminal emulator and then install java and then you can run java apps on standard java. You can even install full Linux distro with x server without rooting the phone, then connect to it from x client and you have Linux desktop on android. Once I've even installed eclipse for java development on it and everything worked. I tested this setup last time in 2014, but I'm pretty sure you can do this nowadays as well. The app with Linux I get from play store as well app for the x client. The app I used back then was "Debian no ROOT" or smthg like this. You need to check what's currently available to make this setup in Google Play store according to your android version and your preferences. Last time I've checked there was a lot of different tools for this kind of task. Lastly I've even successfully installed TF and keras on my android phone using terminal emulator.
You can use JBED. JBED is an .apk Android application which run java games and app on your android Device. JBED is a java android emulator, by using
this application we can install .JAR/.JAD/Java/J2ME/MIDP app on android phones.
You can do it quite easily as there are many ways to run java apps on android. Specific application called Java Emulators can do it quite easily.
These are four most popular java emulators for android viz, JBED, PhoneME, Jblend and NetMite. These are arranged in order of their preference. You can use phoneme for non rooted device, however if your device is rooted try any of the remaining three applications.
I wrote a little app just for a very small group of people over three years ago. Because I have currently enough free time I decided to add a Feature, but I am just able able to find the apk, the key and some icon files(stored on my server). I have changed computer twice, and most likley it got lost somewhere. It would no Problem to complete rewrite the app, but is it possible to recover the app from the apk and my key?
For the most parts of your project the answer is yes. You can decompile your apk to retrieve the java code. This link should be useful:
http://forum.xda-developers.com/showthread.php?t=1910873
I don't know if you can recover the xml-Files like the manifest from the apk.
I going through a simple tutorial to create a very small android app in eclipse. The tutorial is here: http://mobile.tutsplus.com/tutorials/android/android-sdk-development/.
Now that I have it compiling, what should I do to get it on my phone? Do I need to export the app to some sort of exe? can i just copy and paste that exe into some "app" folder on my phone?
You may want to just follow these directions:
http://developer.android.com/guide/developing/device.html
Unless I need real-time debugging, I find it's pretty quick just to squirt the .apk at my phone and hit a few buttons to install and run it. I use Bluetooth which is fast and clean.
I have a file transfer utility for my PC's BT adapter and I simply 'push' the .apk file (from the bin directory) to my phone. Once received, I select it and it's automatically identified as an app package and I'm asked if I want to install it. Once installed I'm asked if I want to run it.
It's great when playing with samples/tutorials which (hopefully) should be bug-free and also when I'm playing around with layouts and UI elements in my own apps.
