안 드 로 이 드 미디어 레 코더 가 화면 을 녹음 할 때 녹음 기능 을 실현 합 니 다.

안 드 로 이 드 얘 기 좀 해 볼 게 요.
최근 에 도 수요 에 부 딪 혀 녹음 기능 을 사용 해 야 하 는 것 아 닙 니까?최근 에 도 만 났 습 니 다.지금 정리 하고 기록 하 세 요.
우선,녹음 화면 은 동적 권한 클래스 를 붙 일 수 있 는 권한 이 필요 합 니 다.

public class TalAllow {
  /**
   * RECORD_AUDIO         
   * WRITE_EXTERNAL_STORAGE     
   * CAMERA            
   */
  public static void requestPermissions(Context context,int allowCode) {
    ArrayList<String> ps = new ArrayList<>();
    int per = ContextCompat.checkSelfPermission(context, Manifest.permission.RECORD_AUDIO);
    if (per != PackageManager.PERMISSION_GRANTED) {
      ps.add(Manifest.permission.RECORD_AUDIO);
    }
    per = ContextCompat.checkSelfPermission(context, Manifest.permission.WRITE_EXTERNAL_STORAGE);
    if (per != PackageManager.PERMISSION_GRANTED) {
      ps.add(Manifest.permission.WRITE_EXTERNAL_STORAGE);
    }
    per = ContextCompat.checkSelfPermission(context, Manifest.permission.CAMERA);
    if (per != PackageManager.PERMISSION_GRANTED) {
      ps.add(Manifest.permission.CAMERA);
    }
    per = ContextCompat.checkSelfPermission(context, Manifest.permission.READ_PHONE_STATE);
    if (per != PackageManager.PERMISSION_GRANTED) {
      ps.add(Manifest.permission.READ_PHONE_STATE);
    }
    Log.d(TAG, "requestPermissions:ps=" + ps.size());
    if (!ps.isEmpty()) {
      String[] ps3 = new String[ps.size()];
      ps.toArray(ps3);
      ActivityCompat.requestPermissions((Activity) context, ps3, allowCode);
    }
  }
}

판단 권한 이 필요 합 니 다.링크 삽입(위 에 있 는 코드 코드 는 100)
권한 여 부 를 판단 하 다
다음 포인트 가 왔 습 니 다.
우선 이 녹음 과 녹음 은 서비스 에서 하 는 것 이 므 로 서비스 류 를 붙 입 니 다.
이 코드 는 분명히 품질 이 있어 서 많은 처 리 를 했 습 니 다.다음 줄 에서 한 줄 씩 해석 하 겠 습 니 다.
