尝试为某些设备生成密钥时出错.我能够在运行4.4.2的三星Galaxy Note上重现错误.

我创建了一个小应用程序,只通过从Android开发者页面https://developer.android.com/training/articles/keystore.html "生成新私钥"下逐行复制代码来生成密钥.

 public void onClickButton (View view) {
    try {
        generateKeyPair(this, "test3");
    } catch (Exception e){
        Log.wtf("exception", e);
    }
}

private void generateKeyPair(Context context, String alias)
    throws Exception { …
