Android - Keyhash

摘要:Android - Keyhash

因為Facebook需要KeyHash,

但用下指令的方式,或許有點麻煩。

 

有一段程式碼,可以直接顯示 KeyHash ,如下


		// Get keyhash for application.
		try {
            PackageInfo info = getPackageManager().getPackageInfo(YOUR_PACKAGE_NAME, PackageManager.GET_SIGNATURES);
            for (Signature signature : info.signatures) {
                MessageDigest md = MessageDigest.getInstance("SHA");
                md.update(signature.toByteArray());
                
                // Log.i(TAG, "KeyHash: " + Base64.encodeToString(md.digest(), Base64.DEFAULT));
			}
        } catch (NameNotFoundException e) {
        		e.printStackTrace();
        } catch (NoSuchAlgorithmException e) {
        		e.printStackTrace();
        }
