我试图将文件夹从资产复制到外部存储，但我有错误消息：
I/System.out: Error :java.io.FileNotFoundException: /storage/emulated/0/heremaps/appcache/sat/12/CURRENT: open failed: ENOENT (No such file or directory)
I/System.out: Error :java.io.FileNotFoundException: /storage/emulated/0/heremaps/appcache/sat/12/LOCK: open failed: ENOENT (No such file or directory)

I/System.out: Error :java.io.FileNotFoundException: /storage/emulated/0/heremaps/assets/here/miami/font/Lohit.LICENSE: open failed: ENOENT (No such file or directory)
...这是我的代码：
private void copyAsset(String path) {
AssetManager manager = getAssets();
// If we have a directory, we make it and recurse. If a file, we copy its
// contents.
try {
String[] contents = manager.list(path);
if (contents == null || contents.length == 0)
throw new IOException();
// Création des dossiers
String destination = Environment.getExternalStorageDirectory().getPath() + File.separator;
File dir = new File( destination + path);
dir.mkdirs();
// Recurse on the contents.
for (String entry : contents) {
copyAsset(path + "/" + entry);
}
} catch (IOException e) {
copyFileAsset(path);
}
}
private void copyFileAsset(String path) {
// File file = new File(Environment.getExternalStorageDirectory().getPath() + "/NTA/" + path);
String destination = Environment.getExternalStorageDirectory().getPath() + File.separator;
File file = new File( destination + path);
try {
InputStream in = getAssets().open(path);
OutputStream out = new FileOutputStream(file);
byte[] buffer = new byte[1024];
int read = in.read(buffer);
while (read != -1) {
out.write(buffer, 0, read);
read = in.read(buffer);
}
out.close();
in.close();
} catch (IOException e) {
System.out.println("Error :" + e);
}

实际上，您需要按照以下方式定义路径：
try{
.........
....
String destination = Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DOWNLOADS);
......
