我正在使用媒體錄音機在android中錄製電話。 mediarecorder有時正在錄製音頻,有些時候它不錄製音頻。當我們播放錄製的音頻時顯示爲「播放器不支持這種類型的音頻文件」的錯誤。媒體記錄器啓動時應用程序崩潰了嗎?
下面的代碼是在錄製音頻以下
E/MediaRecorder: start failed: -38

顯示
try {
f1 = File.createTempFile("Sound", ".mp3", dir);
} catch (IOException e) {
e.printStackTrace();
}
fileName = f1.getName();
mediaRecorder = new MediaRecorder();
mediaRecorder.setAudioSource(MediaRecorder.AudioSource.MIC);
mediaRecorder.setOutputFormat(MediaRecorder.OutputFormat.MPEG_4);
mediaRecorder.setAudioEncoder(MediaRecorder.AudioEncoder.AAC);
mediaRecorder.setOutputFile(f1.getAbsolutePath());
try {
mediaRecorder.prepare();
} catch (IllegalStateException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
mediaRecorder.start();
recordstarted = true;
我logcat的錯誤,請幫助我如何解決這個問題。
錄製的文件存儲在外部storage.when我點擊播放「播放器不支持此音頻」錯誤顯示 –
另外我插入mediaRecorder.start()在try塊 –
