原标题:How to create the signature Hash code for integrating facebook in an android Application?
最佳回答

I have keytool in a different directory:

C:Program 文件(x86)Javajre6in

您也可在<代码>keytool上添加一条途径。 或者,你可以在像你这样整个道路上使用引语。

D:UsersPriyadarshan.android>"C:Program Filesetckeytool.exe" -exportcert etc etc

不要忘记引号,因为路上的空间!

问题回答

keytool comes with the JDK.

阁下发现,假定你在违约情况下安装了JDK:Program filesJavajdk1.6.0_23inkeytool.exe 。

目 录 编造者从面读物记录中取回 has法。

   try {
            PackageInfo info = getPackageManager().getPackageInfo(getPackageName(), PackageManager.GET_SIGNATURES);
            for (Signature signature : info.signatures) {
                MessageDigest md;

                    md = MessageDigest.getInstance("SHA");
                    md.update(signature.toByteArray());
                    String something = new String(Base64.encode(md.digest(), 0));
                   //Toast.makeText(StartingPlace.this, something,
                        //  Toast.LENGTH_LONG).show();
                    Log.e("hash key", something);
        } 
        }
        catch (NameNotFoundException e1) {
            // TODO Auto-generated catch block
            Log.e("name not found", e1.toString());
        }

             catch (NoSuchAlgorithmException e1) {
                // TODO Auto-generated catch block
                 Log.e("no such an algorithm", e1.toString());
            }
             catch (Exception e1){
                 Log.e("exception", e1.toString());
             }
        //code to get hash code
