API 2.3.3 で tar を tar.xz に圧縮しようとしています。

私が何をしても、このエラーが発生します：

それを引き起こしているコードは次のとおりです。

    public void compXZ (String saveAs, String infile) throws IOException {

    FileInputStream fin = new FileInputStream(infile);
    BufferedInputStream in = new BufferedInputStream(fin);
    FileOutputStream out = new FileOutputStream(saveAs);
    XZCompressorOutputStream xzOut = new XZCompressorOutputStream(out);
    final byte[] buffer = new byte[BUFFER];
    int n = 0;
    while (-1 != (n = in.read(buffer))) {
        xzOut.write(buffer, 0, n);
    }

    xzOut.finish();
    xzOut.close();
    fin.close();
}

これのいくつかの異なるバージョンを作成しましたが、すべて同じエラーが発生します。アプリケーションに画像ギャラリーをロードしていますが、ギャラリーをロードせずに圧縮しようとしましたが、同じ結果が得られました。

誰でも問題が何であるか知っていますか? 解決策は何ですか？それとも、tar を tar.xz に圧縮するコードですか?

助けてくれてありがとう。

ジェイダイ。

使用しているXZ圧縮は、67MBのメモリを割り当てようとします。ほとんどのモバイルデバイスでは、これは多すぎます。

XZ圧縮とXZutilsの実装についてはよくわかりませんが、この圧縮アルゴリズムは大量のメモリを必要とし、今日のモバイルデバイスでの使用にはあまり適していないようです。
