android - 安卓录音机

Question

我正在做一个录制声音的应用程序，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。我必须做什么？我不能没有 SD 卡吗？

谢谢!

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

        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();
            }
        }

    }

您可以选择通过 mksdcard 创建一个 SDCard命令并将其与模拟器相关联。
