Android programming method to copy compressed database files to the installation directory

The example of this article describes the method of copying compressed database files to the installation directory through Android programming. Share it with everyone for your reference, the details are as follows:

public void copyZip2DataDirectory(Context context) throws IOException {
  FileOutputStream outputStream = null;
  AssetManager assetManager = context.getAssets();
  InputStream inputStream = assetManager.open("test.zip");
  ZipInputStream zis = new ZipInputStream(inputStream);
  ZipEntry entry = null;
  while ((entry = zis.getNextEntry()) != null) {
   outputStream = context.openFileOutput(entry.getName(), Context.MODE_PRIVATE);
   byte[] buffer = new byte[2 * 1024];
   int len = -1;
   while ((len = zis.read(buffer)) != -1) {
    outputStream.write(buffer, 0, len);
   }
   outputStream.close();
  }
  zis.close();
  inputStream.close();
}

I hope this article will be helpful to everyone’s Android programming design.
