Hello, i’ve been using this juce hack for a while now and it’s mostly ok.
Yes, there are some other boring changes to make it work, i skipped over. let me see…
juce_ComponentPeer.h
// any OS keyboard not required
virtual void textInputNotRequired () {}
juce_android_windowing.cpp. note the hacks to the key codes. i’ve only fixed a few of them so that the basics work.

There are some changes you have to make also to your generated java activity class:
[code]import android.view.inputmethod.InputMethodManager;
…
private native void handleKeyDown (int keycode, int textchar);
private native void handleKeyUp (int keycode, int textchar);
@Override
public boolean onKeyDown(int keyCode, KeyEvent event)
{
handleKeyDown(keyCode, event.getUnicodeChar());
return true;
}
@Override
public boolean onKeyUp(int keyCode, KeyEvent event)
{
handleKeyUp(keyCode, event.getUnicodeChar());
return true;
}
public void showKeyboard(boolean v)
{
InputMethodManager imm = (InputMethodManager)getSystemService(Context.INPUT_METHOD_SERVICE);
if (v)
imm.showSoftInput(this, InputMethodManager.SHOW_FORCED);
else
imm.hideSoftInputFromWindow(getWindowToken(), 0);
}
[/code]
i think that might be it,
– hugh.
