Распакуйте почтовый файл из активов

Question

Я пытаюсь распаковать файл из активов во внешнем хранилище

public class Decompress { 

public static void unzipFromAssets(Context context, String zipFile, String destination) { 
    try { 
     if (destination == null || destination.length() == 0) 
      destination = context.getFilesDir().getAbsolutePath(); 
     InputStream stream = context.getAssets().open(zipFile); 
     unzip(stream, destination); 
    } catch (IOException e) { 
     e.printStackTrace(); 
    } 
}  

public static void unzip(InputStream stream, String destination) { 
    dirChecker(destination, ""); 
    byte[] buffer = new byte[BUFFER_SIZE]; 
    try { 
     ZipInputStream zin = new ZipInputStream(stream); 
     ZipEntry ze = null; 

     while ((ze = zin.getNextEntry()) != null) { 
      Log.v(TAG, "Unzipping " + ze.getName()); 

      if (ze.isDirectory()) { 
       dirChecker(destination, ze.getName()); 
      } else { 
       File f = new File(destination + ze.getName()); 
       f.mkdirs(); 
       File file = new File(f, destination + ze.getName()); 

        FileOutputStream fout = new FileOutputStream(file); 
        int count; 
        while ((count = zin.read(buffer)) != -1) { 
         fout.write(buffer, 0, count); 
        } 
        zin.closeEntry(); 
        fout.close(); 
      } 

     } 
     zin.close(); 
    } catch (Exception e) { 
     Log.e(TAG, "unzip", e); 
    } 

} 

private static void dirChecker(String destination, String dir) { 
    File f = new File(destination + dir); 

    if (!f.isDirectory()) { 
     boolean success = f.mkdirs(); 
     if (!success) { 
      Log.w(TAG, "Failed to create folder " + f.getName()); 
     } 
    } 
} 

Everytime принять эту ошибку:

java.io.FileNotFoundException: filewebViewControllers/aboutAs/index.html/filewebViewControllers/aboutAs/index.html: open failed: ENOENT (No such file or directory)

попробовать это,

Pass the zipfile location and the location where you want the extracted files to be saved to this class while making an object...and call unzip method...

public class Decompress { 
    private String zip; 
    private String loc; 

    public Decompress(String zipFile, String location) { 
    zip = zipFile; 
    loc = location; 

    dirChecker(""); 
    } 

    public void unzip() { 
    try { 
     FileInputStream fin = new FileInputStream(zip); 
     ZipInputStream zin = new ZipInputStream(fin); 
     ZipEntry ze = null; 
     while ((ze = zin.getNextEntry()) != null) { 
     Log.v("Decompress", "Unzipping " + ze.getName()); 

     if(ze.isDirectory()) { 
      dirChecker(ze.getName()); 
     } else { 
      FileOutputStream fout = new FileOutputStream(loc + ze.getName()); 
      for (int c = zin.read(); c != -1; c = zin.read()) { 
      fout.write(c); 
      } 

      zin.closeEntry(); 
      fout.close(); 
     } 

     } 
     zin.close(); 
    } catch(Exception e) { 
     Log.e("Decompress", "unzip", e); 
    } 

    } 

    private void dirChecker(String dir) { 
    File f = new File(_location + dir); 

    if(!f.isDirectory()) { 
     f.mkdirs(); 
    } 
    } 
} 

Создать новую папку для ssdcard для хождения файлы:

String dir = Environment.getExternalStorageDirectory()+File.separator+"myDirectory"; 
    //create folder 
    File folder = new File(dir); //folder name 
    folder.mkdirs(); 

    //create file 
    File file = new File(dir, "filename.extension"); 

Пожалуйста, дайте ниже разрешение вашего файла манифеста:

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