ต้องการความช่วยเหลือ! ข้อผิดพลาดในการรู้จำเสียง

สวัสดีนักพัฒนา Android ฉันกำลังพยายามสร้างการรู้จำเสียงของตัวเองโดยไม่มีกล่องโต้ตอบของ Google แต่มันใช้งานไม่ได้กับอุปกรณ์เกือบจริงที่ฉันมี ข้อผิดพลาด SpeechRecognizer: bind to recognition service failed แต่มันใช้งานได้บน Samsung galaxy win 4.3 แม้ว่าจะมีข้อบกพร่องบางประการก็ตาม ต้องการความช่วยเหลือจากใครสักคนจริงๆ ขอบคุณมาก :) นี่คือรหัสของฉัน:
