Android获取内置和外置SD卡路径，android外置sd路径,本文将介绍android

本文将介绍android真机环境下如何获取内置和外置SD卡路径。

测试环境：三星Note3，其他手机待测试。。。

所需权限（AndroidManifest.xml文件里）

    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />  

获取路径代码（MainActivity.java文件）```java package com.example.androidtest;

import java.io.BufferedReader;  import java.io.File;  import java.io.InputStream;  import java.io.InputStreamReader;  import java.util.ArrayList;  import java.util.List;import android.os.Bundle;  import android.os.Environment;  import android.app.Activity;  import android.view.Menu;public class MainActivity extends Activity {    @Override      protected void onCreate(Bundle savedInstanceState) {          super.onCreate(savedInstanceState);          setContentView(R.layout.activity_main);        StringBuilder log = new StringBuilder();          String inPath = getInnerSDCardPath();          log.append("内置SD卡路径：" + inPath + "\r\n");        List<String> extPaths = getExtSDCardPath();          for (String path : extPaths) {              log.append("外置SD卡路径：" + path + "\r\n");          }          System.out.println(log.toString());      }    /**      * 获取内置SD卡路径      * @return      */      public String getInnerSDCardPath() {            return Environment.getExternalStorageDirectory().getPath();        }    /**      * 获取外置SD卡路径      * @return  应该就一条记录或空      */      public List<String> getExtSDCardPath()      {          List<String> lResult = new ArrayList<String>();          try {              Runtime rt = Runtime.getRuntime();              Process proc = rt.exec("mount");              InputStream is = proc.getInputStream();              InputStreamReader isr = new InputStreamReader(is);              BufferedReader br = new BufferedReader(isr);              String line;              while ((line = br.readLine()) != null) {                  if (line.contains("extSdCard"))                  {                      String [] arr = line.split(" ");                      String path = arr[1];                      File file = new File(path);                      if (file.isDirectory())                      {                          lResult.add(path);                      }                  }              }              isr.close();          } catch (Exception e) {          }          return lResult;      }    @Override      public boolean onCreateOptionsMenu(Menu menu) {          // Inflate the menu; this adds items to the action bar if it is present.          getMenuInflater().inflate(R.menu.activity_main, menu);          return true;      }}

其中，line.contains("extSdCard")判断部分有待进一步验证！ 打印结果：  1. 插入一张外置SD卡后 ```java    内置SD卡路径：/storage/emulated/0      外置SD卡路径：/storage/extSdCard  

2.取出外置SD卡后java内置SD卡路径：/storage/emulated/0来自：http://blog.csdn.net/chadeltu/article/details/43736093
