why my app force close when I use AndroidManifest.xml

Sorry, i just saw your command. you should include appropriate AndroidManifest.xml in your unity project. (creating eclipse project, adding classes ...) or simply change bundle identifier in your unity project

Sorry taesiri, i already did as you post, but i could not see the result of it.

سلام آقای تأثیری
از نام شما حدس زدم که احتمالا ایرانی باشید
محمد رضا عزیز! من در حال ساخت یک مسنجر در یونیتی هستم و از این طریق پست شما رو دیدم. مشکلی دارم که خواستم بدونم امکانش هست که شما به من کمک کنید؟
مشکل من آن است که ارتفاع کیبورد در یونیتی در اندروید قابل دریافت نیست و همیشه عدد صفر را نشان میدهد
فیلد اینپوت تکست هم قابل ادیت نیست! خیلی سرچ کردم و یک ماه است که درگیر این مسئله هستم.
بهترین پاسخی که دیدم لینک زیر است ::

ولی نتوانستم با آن هم موفق شوم
خوشحال میشوم صدای شما را بشنوم

Hello. It's not worked for me. Unity 5.3.4

With manifest file app force closed. I delete manifest file and build. But when I press SendSMS, nothing happens

I create another gist based on this code but without creating a java plugin, just in case somebody need it https://gist.github.com/rmdwirizki/87f9e68c7ef6ef809a777eb25f12c3b2

@rmdwirizki: Your code works like a charm and it's much easier for me to use. Thank you.

ببخشید بنده از همین راه رفتم . ولی با ارور رفرنس مواجه میشدم . در خطهایی که مواردی مثل
_activityObject.Call("sendSMSMessage", _phoneNumber, _messageBody);
وجود داشت
به این ها گیر میداد . چیکار میشه کرد اقای تاثیری؟
