如何在android studio中获取SHA1指纹证书

Question

用于调试的 SHA1

keytool -list -v -keystore ~/.android/debug.keystore -alias androiddebugkey -storepass android -keypass android

用于发布的 SHA1

keytool -list -v -keystore "/home/compe18/Keystore folder/keystore.jks" -alias keystore Alias Name -storepass password -keypass password

注意：storepass和keypass是应用Keystore密码，keystore = keystore path,alias = Key alias Name（创建Keystore时使用的名字）.....

你也可以运行以下代码：

try {
         PackageInfo info = getPackageManager().getPackageInfo(
                           "yourpackagename", 
                            PackageManager.GET_SIGNATURES);
         for (Signature signature : info.signatures) {
                    MessageDigest md = MessageDigest.getInstance("SHA");
                    md.update(signature.toByteArray());
                        Log.d("KeyHash:", Base64.encodeToString(md.digest(), Base64.DEFAULT));
                  }
            } catch (NameNotFoundException e) {

      } catch (NoSuchAlgorithmException e) {}    
}
