录音机Android

Question

我正在录制声音，但是当我尝试录制声音时，模拟器停止了，因为它要求我插入SD卡。我该怎么办？我不能没有SD卡吗？

谢谢！

        }

        @Override
        public boolean onCreateOptionsMenu(Menu menu) {
            // Inflate the menu; this adds items to the action bar if it is present.
            getMenuInflater().inflate(R.menu.main, menu);
            return true;
        }

        public void grabar(View v) {
            Intent intent = new Intent(MediaStore.Audio.Media.RECORD_SOUND_ACTION);
            startActivityForResult(intent, peticion);}

            public void setOutputFile(FileDescriptor fd) {
                    switch (mState) {
                case STATE_RECORD:
                        throw new RuntimeException("setOutputFile cannot be called while recording!");

                    case STATE_RELEASED:
                        throw new RuntimeException("setOutputFile called on an already released recorder!");
                    default:
                        break;
                }
        }

        public void reproducir(View v) {
            MediaPlayer mediaPlayer = MediaPlayer.create(this, url1);
            mediaPlayer.start();
        }

        protected void onActivityResult(int requestCode, int resultCode, Intent data) {
            if (resultCode == RESULT_OK && requestCode == peticion) {
                url1 = data.getData();
            }
        }

    }

Answer 1

您可以选择通过mksdcard命令创建SD卡，并将其与amulator相关联。

Answer 2

请看这个功能：

public void setOutputFile (FileDescriptor fd)

Added in API level 3
Pass in the file descriptor of the file to be written. Call this after setOutputFormat() but before prepare().

您可以决定存储文件的位置。
