java - 错误: cannot find symbol class Base64

Question

import org.apache.commons.codec.binary.Base64;
import java.util.Base64;

运行代码时出现错误。

    private void upload() {
    Bitmap bm = BitmapFactory.decodeFile(mCurrentPhotoPath);
    ByteArrayOutputStream bao = new ByteArrayOutputStream();
    bm.compress(Bitmap.CompressFormat.JPEG, 50, bao);
    byte[] ba = bao.toByteArray();
    ba1 = Base64.encodeBytes(ba);

    // Upload image to server
    new uploadToServer().execute();

}

我遇到的错误是:

Error:(81, 21) error: cannot find symbol method encodeBytes(byte[])
Error:(43, 25) error: cannot find symbol class Base64

Answer 1

您正在导入 Java 库。请使用 Base64 的 android 库。

import android.util.Base64;
