Android集成高德定位SDK，报ErrCode:7错误解决

由于开发需要将项目从eclipse迁移到androidStudio上，结果运行就报错 ErrCode:7 errInfo:KEY错误；

查找官方文档，说SHA1错误

（接手的别人的项目）没办法啊，那就只有重新申请key了，重新获取SHA1，各种折腾，还是说key错误

最后在网上找到这个方法  （加在定位前）

//获取SHA1的方法===================================================================

            public staticString sHA1(Context context) {

                try{

                        PackageInfo info = context.getPackageManager().getPackageInfo(

                        context.getPackageName(), PackageManager.GET_SIGNATURES);

                        byte[] cert = info.signatures[0].toByteArray();

                        MessageDigest md = MessageDigest.getInstance("SHA1");

                        byte[] publicKey = md.digest(cert);

                        StringBuffer hexString =newStringBuffer();

                        for(inti =0; i < publicKey.length; i++) {

                        String appendString = Integer.toHexString(0xFF& publicKey[i])

.                        toUpperCase(Locale.US);

                        if(appendString.length() ==1)

                        hexString.append("0");

                        hexString.append(appendString);

                    }

                   returnhexString.toString();

                 }catch(PackageManager.NameNotFoundException e) {

                        e.printStackTrace();

                 }catch(NoSuchAlgorithmException e) {

                        e.printStackTrace();

                 }catch(Exception e) {

                        e.printStackTrace();

                 }

            return null;

          }

//获取SHA1的方法===================================================================

在代码中获取SHA1,注意 获取到的SHA1没有  “：”，需自己添加上去，然后将它拷贝到  调试版安全码SHA1 中，这次终于好了，可以正常定位了。

大家可以试试，亲测有效！
