Question

我使用了一些其他问题中提供的代码，这些代码应该是正确的，我没有理由怀疑它是什么，但现在当我启动应用程序时，我得到的就是：

java.io.IOException: An established connection was aborted by the software in your host machine

用于复制的方法是从Main活动启动的，如下所示：

private void copyAssets()
{
    //iegust failu sarakstu
    AssetManager assetManager = getAssets();
    String[] files = null;
    try {
        files = assetManager.list("");
    } catch (IOException e) {
        Log.e("tag", "didnt get", e);
    }
    for(String filename : files) {
        InputStream in = null;
        OutputStream out = null;
        try {
          in = assetManager.open(filename);
          File outFile = new File(getExternalFilesDir(null), filename);
          out = new FileOutputStream(outFile);
          copyFile(in, out);
          in.close();
          in = null;
          out.flush();
          out.close();
          out = null;
          Log.d("tag","Success");
        } catch(IOException e) {
            Log.e("tag", "Didnt copy: " + filename, e);
        }       
    }
}
//kope failu
private void copyFile(InputStream in, OutputStream out) throws IOException {
    byte[] buffer = new byte[1024];
    int read;
    while((read = in.read(buffer)) != -1){
      out.write(buffer, 0, read);
    }
}

Answer 1

要在SD卡中写入文件，您必须授予清单

的权限

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

Answer 2

你可以张贴你的清单吗？您应该将以下权限添加到您的MANIFEST

 <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"></uses-permission>
 <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"></uses-permission>

将资产复制到sdcard时使用java.io.IOException（使用assethelper）
