I want to send custom error report

ACRA.getErrorReporter().putCustomData("syncBadUrl", url);
ACRA.getErrorReporter().handleSilentException(e);

after this my app not crashed, but this report not sended. In logcat I see this:

                .setFormUri(crashReportUrl)
                .setReportingInteractionMode(ReportingInteractionMode.DIALOG)
                .setResDialogText(R.string.crash_dialog_text)
                .setResDialogTitle(R.string.crash_dialog_title)
