我在音頻應用程序的工作， 但是當試圖創建PCM文件，這裏的代碼崩潰：Android的崩潰，當文件
public class RecordPCM {
public void record() {
Log.d("mensaje","Recording testeo started");
int frequency = 11025;
//int channelConfiguration = AudioFormat.CHANNEL_CONFIGURATION_MONO;
int channelConfiguration = AudioFormat.CHANNEL_IN_MONO; //cambiado por el de arriba por deprecado
int audioEncoding = AudioFormat.ENCODING_PCM_16BIT;
File file = new File(Environment.getExternalStorageDirectory().getAbsolutePath() + "/reverseme.pcm");
// Delete any previous recording.
if (file.exists()) {
file.delete();
Log.d("mensaje","file exists!!!");
}
// Create the new file.
try {
file.createNewFile();
} catch (IOException e) {
throw new IllegalStateException("Failed to create :::: " + file.toString());
}
try {
// Create a DataOuputStream to write the audio data into the saved file.
OutputStream os = new FileOutputStream(file);
BufferedOutputStream bos = new BufferedOutputStream(os);
DataOutputStream dos = new DataOutputStream(bos);
// Create a new AudioRecord object to record the audio.
int bufferSize = AudioRecord.getMinBufferSize(frequency, channelConfiguration, audioEncoding);
AudioRecord audioRecord = new AudioRecord(MediaRecorder.AudioSource.MIC,
frequency, channelConfiguration,
audioEncoding, bufferSize);
short[] buffer = new short[bufferSize];
audioRecord.startRecording();
boolean isRecording = false; //metido para arreglar
while (isRecording) {
int bufferReadResult = audioRecord.read(buffer, 0, bufferSize);
for (int i = 0; i < bufferReadResult; i++)
dos.writeShort(buffer[i]);
}
audioRecord.stop();
dos.close();
} catch (Throwable t) {
Log.d("mensaje","Recording Failed");
}
}
public void copio(){
Log.d("mensaje","Recording testeo");
}
}
所以當我打電話
recordObject.record();
該應用程序崩潰與錯誤：

所以
什麼讓我的應用程序崩潰，
爲什麼與我的顯示logcat的？
謝謝！
