我必须加密一个字符串,但应用程序未达到加密方法,它在加载时崩溃。 我正在使用Apache Commons Codec库。
private EditText txtPass = (EditText)findViewById(R.id.txtPass); public String key = txtPass.getText().toString(); public byte[] key_Array = org.apache.commons.codec.binary.Base64.decodeBase64(key);
由于某种原因,该应用程序在第三行崩溃。
我的logcat。

有什么线索吗?
更新
我将代码更改为此:
public static String key = "1234"; public static byte[] key_Array = decodeBase64(key);
但是现在我又遇到了其他错误
java.lang.NoSuchMethodError: org.apache.commons.codec.binary.Base64.decodeBase64
试试这个:
// decode data from base 64 private static byte[] decodeBase64(String dataToDecode) { byte[] dataDecoded = Base64.decode(dataToDecode, Base64.DEFAULT); return dataDecoded; } //enconde data in base 64 private static byte[] encodeBase64(byte[] dataToEncode) { byte[] dataEncoded = Base64.encode(dataToEncode, Base64.DEFAULT); return dataEncoded; }
