已经下载Demo的可以直接到第五步，已经配置好的并可以运行的可以直接到第七步。
1.在浏览器搜索 ” 百度定位API “，点击下面这个链接
2.翻到最下面找到并点击 ” Android定位SDK “
3.在左侧导航找到 " 产品下载"
4.点击DEMO下载，这个DEMO就开始下载了
5.从文件夹打开并解压
6.此时的文件还不能用自己的Android Atudio打开，需要配置一些参数
7.可以此时项目能够打开，但是要实现定位功能还需要获取ak鉴权
从16分56秒开始 ak鉴权获取教程
获取SHA1代码
public static String 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 = new StringBuffer();
for (int i = 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);
hexString.append(":");
}
String result = hexString.toString();
System.out.println("SHA1:"+result);
return result;
} catch (PackageManager.NameNotFoundException e) {
e.printStackTrace();
} catch (NoSuchAlgorithmException e) {
e.printStackTrace();
}
return null;
}
8.Android Atudio打开文件后就可以正常运行啦
9.抽取上面提到的功能
通过MainActivity.java找到需要实现的功能的代码
然后将lib文件夹、servlet文件夹、LocationService.java、AndroidManifest.xml复制到自己的项目中，调试一下基本就可以运行了。
