[android-developers] Re: how to inject non-english characters
Hi!
I'm also injecting keys, but I have developed a custom keyboard using
/dev/uinput. I need to translate unicode keys to android key events and I'm
using the getEvents method on KeyCharacterMap class like you guys. I'm also
facing the same problem, that accented characters can not be inserted --
getEvents returns no events for such character arrays. Even if character
array contains regular characters and then an accented character, nothing
is returned.
Is there something wrong with how we're using getEvents or perhaps some
other method that would return the required KeyEvents?
Regards,
Miha

Hi LeenuxGuy,
I found kind of a solution:
1. Backup clipboard content
2. Put your character in clipboard
3. Inject menu-key, then v-key. This is a keyboard shortcut for
pasting the clipboard.
4. Unfortunately Android is inserting spaces before and after the
content in some cases.
Try to remove them by injecting DPAD_LEFT, DELETE
5. Put the backed up clipboard content back in the clipboard.
That is in fact so ugly and unreliable, that I discarded it right away.
* On some phones the paste shortcut also triggers the menu.
* There is a racecondition in the clipboard. Sometimes the old
clipboard content is pasted instead of the just inserted character.
* I can't get rid of these spaces reliably. I don't know why Android
is doing this. That's even a pain when using the clipboard the
intended way.
So, currently I stick with english characters. Sorry.
I would be glad to hear from you, when you got a solution.
Best regards,
Hardy

Hi Hardy,
Did you ever find a solution for this? I also have a signed app with
INJECT_EVENTS permissions, and I want to be able to send any character
(English or otherwise) on to various EditText fields, based on external
input.

KeyEvent[] keyEvents = m_KeyCharacterMap.getEvents(chars);
if (keyEvents != null) {

}
That works perfectly on english characters (The characters show up in
EditText boxes). However, if I am trying to inject e.g. korean
characters, this fails. The function getEvents returns null, even when
I have configured korean language and keyboard.
I know there is another mehtod for injecting strings directly:
KeyEvent event = new KeyEvent(SystemClock.uptimeMillis(), str, 0,
0);
instr.sendKeySync(event);
This is not working either - no characters shown in EditText boxes,
and onKeyMultiple() is not called either in my test activity.
This is strange since dispatchKeyEvent() with the same event works in
my test activity:
KeyEvent event = new KeyEvent(SystemClock.uptimeMillis(), str, 0,
0);
dispatchKeyEvent(event);
I believe injecting the string directly is the correct way. However,
using instrumentation it looks like the event is discarded somewhere
in Android.
The reason why I am not using dispatchKeyEvent is that I have to
inject events no matter which activity is in front, even it is not my
own activity. I think that is not possible using dispatchKeyEvent, is
it?
Using Instrumentation this is possible. At least with english
characters. (My app is signed with the platform key and I've got the
permission INJECT_EVENTS).
How am I supposed to inject non-english characters? Any ideas? I ran
out of ideas :(
