我正在嘗試在我的 android 項目中實現 musicg 庫。我已經成功地將它導入到我的項目中，并嘗試使用它來比較兩個音頻文件并獲得它們之間的相似性。這是我的代碼：final String rootPath = Environment.getExternalStorageDirectory().getPath() + "/Myapp/music/";String p1 = rootPath + "outputfiles/1.wav";String p2 = rootPath + "outputfiles/com.wav";Wave w1 = new Wave(p1);Wave w2 = new Wave(p2);FingerprintSimilarity fingerprintSimilarity = w1.getFingerprintSimilarity(w2);float score = fingerprintSimilarity.getScore();float similarity = fingerprintSimilarity.getSimilarity();Log.d("Similar sound :", "Score : " + score + "\n Similarity : "+ similarity);但是當我運行它時，我的應用程序崩潰了： FingerprintSimilarity fingerprintSimilarity = w1.getFingerprintSimilarity(w2);我也調試了我的應用程序，但調試報告中沒有報告錯誤。請幫我。先感謝您

可能是文件不存在或波形格式不正確？我建議添加更多調試信息以查看問題，例如：
try {
final String rootPath = Environment.getExternalStorageDirectory().getPath() + "/Myapp/music/";
String p1 = rootPath + "outputfiles/1.wav";
Log.d("p1 " + p1);
File f1 = new File(p1);
Log.d("f1 " + f1.exists() && !f1.isDirectory());
String p2 = rootPath + "outputfiles/com.wav";
Log.d("p2 " + p2);
File f2 = new File(p2);
Log.d("f2 " + f2.exists() && !f2.isDirectory());
Wave w1 = new Wave(p1);
Log.d("w1 " + w1);
Wave w2 = new Wave(p2);
Log.d("w2 " + w2);
FingerprintSimilarity fingerprintSimilarity = w1.getFingerprintSimilarity(w2);
Log.d("fingerprintSimilarity " + fingerprintSimilarity );
float score = fingerprintSimilarity.getScore();
Log.d("score " + score );
float similarity = fingerprintSimilarity.getSimilarity();
Log.d("Similar sound :", "Score : " + score + "\n Similarity : "+ similarity);
} catch (Exception e) {
Log.d("Error" + e.getMessage());
}
