File Picker

Hi, I am porting a Nintendo Gameboy Color emulator. I want to provide the users the option to pick a ".gb" or ".gbc" file. The "clicked" callback of the button and the result callback of app control looks like this.

static void app_control_result(app_control_h request, app_control_h reply, app_control_result_e result, void *user_data)
{
    char *value;
    if(result == APP_CONTROL_RESULT_SUCCEEDED)
    {
        int ret = app_control_get_extra_data(reply, APP_CONTROL_DATA_PATH, &value);
        if ( ret == APP_CONTROL_ERROR_NONE)
        {
            dlog_print(DLOG_INFO, LOG_TAG, "[app_control_extra_data_cb] Succeeded: value(%s)", value);
        }
        else
        {
            dlog_print(DLOG_ERROR, LOG_TAG, "[app_control_extra_data_cb] Failed: Error code: %d", ret);
        }
    }
    else
    {
        dlog_print(DLOG_ERROR, LOG_TAG, "[app_control_result_cb] APP_CONTROL_RESULT_FAILED. Error code: %d", result);
    }
}



void clicked_cb(void *data, Evas_Object *obj, void *event_info)
{
    appdata_s *ad = data;


    app_control_h app_control;
    app_control_create(&app_control);
    app_control_set_operation(app_control, APP_CONTROL_OPERATION_PICK);
    app_control_send_launch_request(app_control, app_control_result, ad);
    app_control_destroy(app_control);
}

Picking a file with the built in file explorer I get : [app_control_extra_data_cb] Failed: Error code: -126

I have added mediastorage, externalstorage and other data related privileges in the manifest file. What am I doing wrong?

I do not see the calling for app_control_add_extra_data() before your call app_control_send_launch_request().

Inside app_control_result(), you called app_control_get_extra_data() to get the extra data, but you have not passed in your extra data at all.

So, please call app_control_add_extra_data() firstly before you call app_control_send_launch_request().

Here is the tutorial you can reference:

https://developer.tizen.org/development/tutorials/native-application/application-framework/application

And the example at section: Running Applications Using Extra Data.

For the file you want to pick, you may need following reference for filesystem:

Hi,

[app_control_extra_data_cb] Failed: Error code: -126.

TIZEN_ERROR_KEY_NOT_AVAILABLE = -ENOKEY, /**< Required key not available */

#define    ENOKEY        126    /* Required key not available */

As your sample code, 

int ret = app_control_get_extra_data(reply, APP_CONTROL_DATA_PATH, &value);

-126 means there isn't extra dat key APP_CONTROL_DATA_PATH.

 

I've ever encounter such issue, in my case,  the key is "path",

ret = app_control_get_extra_data(reply, "path", &value);

Notice that I am using app_control_get_extra_data() on the reply app control, which is supposed to be filled by the application that was called to do the task. In this case, I am opening a file browser and that file browser is supposed to return to me the path of the file selected by the user. That is what I understood. What am I supposed to send as extra data to the file browser?

@Colin

I have tried using "path" as the key, but still did not get the path. Seems like "path" only works for img MIME types.

Hi,

Yes, my case is to open a browser to select an image.

Try more, to foreach all the keys on reply handler.

app_control_foreach_extra_data(reply, foreach_extra_data_cb, NULL);
static bool
foreach_extra_data_cb(app_control_h app_control, const char *key, void *user_data)
{
    char *value;
    int ret;

    ret = app_control_get_extra_data(app_control, key, &value);
    if ( ret == APP_CONTROL_ERROR_NONE)
    {
        dlog_print(DLOG_INFO, LOG_TAG, "[app_control_extra_data_cb] Succeeded: key(%s), value(%s)", key, value);
    }
    else
    {
        dlog_print(DLOG_ERROR, LOG_TAG, "[app_control_extra_data_cb] Failed: key(%s), Error code: %d", key, ret);
        return FALSE;
    }
    return TRUE;
}

I get a single line:

[app_control_extra_data_cb] Failed: key(http://tizen.org/appcontrol/data/selected), Error code: -126

Can you try it?

There are no document or spec for picking file. so we should be prepared for array reply or not.

static void ac_cb(app_control_h request, app_control_h reply, app_control_result_e result, void *user_data)
{
    appdata_s *ad = user_data;
	if (result == APP_CONTROL_RESULT_FAILED ) {
		LOGI("app control failed");
		return;
	}
	if (result == APP_CONTROL_RESULT_CANCELED) {
		LOGI("app control canceled");
		return;
	}

	bool is_array;
	app_control_is_extra_data_array(reply, "path", &is_array);

	ad->path[0] = '\0';
	if (is_array) {
		int i, count = 0;
		char **paths = NULL;
		app_control_get_extra_data_array(reply, "path", &paths, &count);

		if (paths != NULL) {
			for(i=0; i<count; i++) {
				LOGI("file selected : %s", paths[i]);
			}
			if (count > 0) strcpy(ad->path, paths[0]);
			for(i=0; i<count; i++) free(paths[i]);
			free(paths);
		} else {
			LOGI("file select failed!");
		}
	} else {
		char *path = NULL;
		app_control_get_extra_data(reply, "path", &path);
		if (path != NULL) strcpy(ad->path, path);
		else LOGI("file select failed!");
		free(path);
	}
	LOGI("file selected : %s", ad->path);
}

static void btn_clicked(void *data, Evas_Object *obj, void *event_info)
{
	appdata_s *ad = data;
	app_control_h ac;
	app_control_create(&ac);
	app_control_set_operation(ac, APP_CONTROL_OPERATION_PICK);
	app_control_send_launch_request(ac, ac_cb, ad);
	app_control_destroy(ac);
}

That woked like a charm. Thanks a lot man. I was giving up hope. Marked as the answer :D
