Live Android Programming

Online java programming for android, execute source code snippets which get compiled and dynamically loaded into the app at runtime. Useful as a development tool for rapid prototyping and to learn java android programming. You start with a blank page and create the app as you program.

1.) Point your browser to runondroid.com

2.) Execute android code snippets

3.) Share code snippets

For example, execute this to show a toast message:

Toast.makeText(getApplicationContext(),"Hello World!",Toast.LENGTH_LONG).show();

The permissions are added so you can use the Android API, for example to read the accelerometer.

More examples:

- add a button to the app programmatically at runtime

- quickly read the GPS coordinates from your phone.

- Read and Write Files

Program the functionality you want and execute it immediately.

Variables you define are stored in the runtime environment. Variable details are shown for debugging. You can define whole classes.

Great for rapid prototyping, just test if the code works on your phone without using an IDE and the SDK.

You can execute commands like in the onCreate method.

Use "this" to get the ActionBarActivity.

Define classes.

The layout ressource is R.id.myLinLayout.

There are convenience methods especially for the browser connection:

- consoleLog(String s) logs to the browser

- downloadFile(String fileName) from your phone to your computer.

All connections are TLS encrypted (except for the ads).

Now with code completions!
