Just to clarify: You want to send commands from adb shell (local android shell) to your app? That's not possible without quite a few lines of code, and possible requires rooting of the device.

You'd be better of by just adding an UI to the app where you can call events.

Edit: As m0skit0 pointed out it is possible to send intents via commandline. This is definitely the cleanest solution.

You can send Intents to your app through the shell, although your app has to register the appropriate BroadcastListener. Here's a simple example:

public class MyActivity extends Activity {

    private static final String TAG = MyActivity.class.getSimpleName();

    public static final String INTENT_FILTER = "com.example.myapp.TEST";
    public static final String EXTRA_KEY = "new_text";

    private class MyIntentReceiver extends BroadcastReceiver {
        @Override
        public void onReceive(final Context context, final Intent intent) {
            final String newText = intent.getExtras().getString(EXTRA_KEY);
            Log.d(TAG, "Received new text: " + newText);
        }
    }

    /**
     * Called when the activity is first created.
     */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        registerReceiver(new MyIntentReceiver(), new IntentFilter(INTENT_FILTER));
    }
}

Then you can do in shell:

am broadcast -a com.example.myapp.TEST -e "new_text" "New text"

And you will see how your app receives and logs it.
