So I am writing code in java in google colab because I want to copy-paste the code in android studio to perform a specific function. Now in python it is pretty easy to upload files to google colab but I want to do it in java (I particularly want to upload image files). I should be able to upload image files in such a way that I can use it as input in my code. How can I do it? Also, for all the packages that I import in google colab, will I have to separately download them for android studio or can I just copy-paste the code and it will run?
Google Colab presents a Jupyter-notebook like environment for Python code only. It cannot run Java code (at least, I cannot find where you'd make it do that).
I want to copy-paste the code in android studio to perform a specific function
Android code runs on an Android device, not in a server.
If you want to run Java code on a server, then you'd host an HTTP-based Java web-server that you use an HTTP Client from Android app to communicate with it. (In theory, yes, you can install and run JAR files in Colab, but you would then need to know the IP of those servers in order to connect with them).
The more appropriate solution would be to use Google AppEngine or GCE/GKE (assuming you want to use Google Cloud)
I ... want to upload image files
You can use the Java Google Drive SDK for that
for all the packages that I import in google colab, will I have to separately download them for android studio
Android Studio is an IDE. Gradle will download packages for compiling your Java/Android code, yes, but as mentioned, Colab is downloading Python packages, not Java

I need to work on the iOS version of my app. The App-Engine and Android portions are completed using the Google Eclipse Plugin (GPE). In the Official Google Documentations I am told the easiest way is to use maven. Does anyone know how I might add maven to the App-Engine portion of my “connected” project?
Apparently I only need to add the following one line in the maven file
mvn appengine:endpoints_get_discovery_doc
Update
Again, I need to get the iOS client for an endpoint project that I created with the Google Eclipse Plugin as an App-engine Connected Android Project. From eclipse I simply do [Right Click] > Google > Generate Cloud Endpoint Client Library and it generates the library for android. But now I just look in my war directory and I see three files: myendpoint-1-rest.discovery, myendpoint-1-rcp.discovery, myendpoint-1-rest.api.
Now this is a wild guess, but are these the files I need for iOS and JavaScript? Or must I follow the instructions in the official docs to get the discovery files for iOS? What I mean is I have not generated the files per the instructions but I have used the GPE for creating the endpoints for android. Does GPE create the necessary clients for iOS and JavaScript as well? I cannot find any documentation on that.
Javascript client only needs to include script https://apis.google.com/js/client.js. You can load your API using
gapi.client.load('api-name', 'v1', callback, 'https://app_id.appspot.com/_ah/api');
Objective-C client needs some extra work after generating your discovery doc.
Is there an easy way to run Java code on an Android device without actually delivering an apk? I'd like to test out function calls without building an entire project.
For instance, it would be cool to run calls like Camera.open(1) and see what the device responds with. It takes forever to rebuild an entire project and redeploy it for minor changes. The only option I can come up with is having some sort of text field that takes user input, executes commands (Compiler API?) and displays the result. Is there a better way?
There is the Android Scripting Layer
https://code.google.com/p/android-scripting/
There is Dev Apps Direct for looking and loading sample open source libraries.
There is API Demos which is just the official samples from the android sdk that a third party published on Google Play
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 have recently started programming for the Android platform. I have a simple application which I would like to email to someone so that they can execute the application and check how it works.
I am currently using the Emulator in the Android SDK to execute my application but the person who I am emailing it to does not have Android SDK and it would be a mission to send the whole project folder.
Is there any way that I can send just one file such as an .exe or something that would allow the recipient to execute the application to see how it works.
Thanks so much for your help in advance guys
The "exe" for android is called apk. I suggest you to look at this question. You'll need to build the apk and sign it in order to be able to run it.
If you just want to send it to a user for testing purposes, you can enable the setting in the target android device to allow "unknown sources" (I don't know the proper english name, as I don't have an english android here at the moment). You can find this in the app settings.
In your development environment look for the apk file created by eclipse. Then connect your smartphone to the pc and copy the apk over. Start up a file manager and click on the apk and it will install just like any other app.
If you want to deploy it properly, you have to sign it and probably follow the procedures from google. Since I don't have a fully deployable app yet, I can't say what the procedures is for that, but the google site is very helpfull on all aspects about android programming.
Check the "bin" folder in your project path. There you will have a .apk that you can share with your clients.
If they execute it in an Android mobile phone the application will be installed.
What alteration should be made in a Java Application to be able to install it on Java Enabled Smartphone?
I tried using a random app of mine to see what happens, when I open it on the cell, it says Install? I say yes, and it says invalid file.
Now I was wondering what alteration should be made?
My smartphone (Samsung S8500) runs on bada which is more or less the same as Android, but alterations in the General.
You need different SDK for smartphones. Like for Android, you need Android SDK 1.5 or any other version. You just cannot install the same application. You need to develop using the resources provided by the SDK.
If your application is Java based mobile application then you can use some tools to convert it for Android. Doesn't work every time but worth a try.
In your case, Bada OS is not like Android what i learn from here. So, you need to develop the application using J2ME .
