AIDE - Android Java IDE is an integrated development environment (IDE) for developing real Android Apps directly on Android devices. AIDE supports the full edit-compile-run cycle: write code with the feature rich editor offering advanced features like code completion, real-time error checking, refactoring and smart code navigation, and run your App with a single click.
AIDE will turn your Android tablet with keyboard into a real development box. We use the Transformer Prime running Ice Cream Sandwich to code with AIDE. AIDE will turn your Android Phone into a small development computer to browse and touch your code on the go.
AIDE is fully compatible with Eclipse projects. Just copy the sourcecode to your device, open any source file in AIDE to load the project and start coding.
