Question

I have a snippet of code creating a new String as follow:

private final static Charset UNICODE_CHARSET = Charset.forName("UTF-8");

public String makeNewUnicodeString(byte[] octects) {
    return new String(octects, UNICODE_CHARSET);
}

It works fine when testing on my computer. But when I run it on Android emulator, it throws:

java.lang.NoSuchMethodError: java.lang.String.<init>

But this works:

public String makeUnicodeString(byte[] octets) {
    try {
        return new String(octets, "UTF-8")
    } catch (UnsupportedEncodingException uee) {
       // never throw.
    }
}

I’m using Android 2.2 API 8, rev 2.

Answer 1

Since the constructor String (byte[] data, Charset charset) was only added in API Level 9 (Android SDK 2.3). So updating SDK version solved my problems. Thanks everyone.
