5 Best Android Apps For Java Developers

1. JavaIDEdroid

Download the App on the Google Store by clicking this Button
“JavaIDEdroid is an integrated development environment which runs on Android and allows to create native Android applications without the need to use the Android SDK on Windows or Linux.

You need Android 2.2.3 or higher and a storage card (/sdcard/) to use this app!

Following development tools are integrated in JavaIDEdroid:
* aapt tool
* Eclipse compiler for Java
* dx tool
* DexMerger tool
* ApkBuilder
* zipsigner-lib (this library also does the zipalign)
* SpongyCastle Library
* BeanShell Interpreter
* JavaRunner: allows to run any binary Java commandline application (.jar file)

The APP can be extended with modules. The modules are loaded dynamically and the integrity of the module is checked before every start of the module. In the download area of the project’s website you’ll find some pre-built modules, for example for Ant or the jar tool.

The APP can be controlled and customized with BeanShell scripts. The APP supports the ‘protected script mode’ which verifies the integrity of the scripts before executing them.

The software supports project features:
* Project definition files: Allows to define project specific information for every project.
* Default scripts: Due to the project definition files, it is possible to use default BeanShell scripts (for compiling and building) which fit almost all projects. The default scripts can be started from the project menu and can be customized if needed.
* Project template: When creating a new project definition files, you can tell the app to create a skeleton project for you.
* Recent project list: Allows to quickly re-open recent projects
* Project filemanager: Allows you to browse all your project files and create, open, edit, delete and run (only .bsh files) them. There is a ‘Directory list’ button that lets you quickly change to another subdirectory of the project.
* Project time log: Allows you to see the time spent for development

By installing the JavaIDEdroidPRO key (or the old JavaIDEdroidPRO 1.x app) additional features become available:
* Unlimited project support (the free version only supports very small projects)
* DexMerger Tool: Allows to merge 2 .dex files. So, .jar libraries do not need to be re-dexed everytime.
* dx: Merge functionality
* dx: Incremental option
* APK signing with user certificate
* Unlimited JavaRunner (the free version only supports very small .jar files and only 1 module at a time)

The Permission is used, so that Java console applications can access the Internet. JavaIDEdroid itself does not need the Internet access.

For more details see the online version of the built-in help file: http://www.tanapro.ch/products/JavaIDEdroid/help-en.html

Check the project web site for more information and support:
https://github.com/t-arn/java-ide-droid/wiki
In the Wiki you’ll find a HowToGetStarted tutorial:
https://github.com/t-arn/java-ide-droid/wiki/1.-How-to-get-started
In the Wiki you’ll also find a guide on how to create and use the module for the free Java obfuscator yGuard.
There, you’ll also find how to create Codename One applications on your Android device.

Please check the support forum before rating this app badly. We will give our best to help you there.

2. CodeGym: learn Java

Download the App on the Google Store by clicking this Button
“Learn Java programming from scratch on your smartphone with the educational quest game from creators of CodeGym. The course consists of 1200 tasks and 600 mini-lectures.

If you dream of becoming a programmer, but you’re short of time for learning on courses with a demanding schedule, here’s a solution. With this app, you can devote as much time for your learning as you have, and practice wherever you want. Even 30 minutes a day would be enough for reading a couple of lectures or solving a few tasks 🙂

Our Java programming course is designed in a playing format and includes four quests. Each quest consists of 10 levels with lectures and tasks. Imagine you play a game and skill-up your character along with actually learning how to code!

Of course, it’s quite a tough task to write dozens of code lines on your smartphone. With this aim in view, we’ve developed a fully-featured system of auto expands and tips to help you code faster. After you write the solution, send it for review and get instant verification.

There’s a whole lot of Java tasks in the course, such as:

– Writing your code;
– Fixing existing code;
– Self-consistent mini-projects and games.

If you run into sticky points while solving any task, feel free to ask for a hint in the help section and get advice from other students or course developers.

We save your progress, so you can return to learning any minute and continue with solving tasks or reading lectures.
