获得机身存储路径(可以通过openFileInput,openFileOutput进行操作)
String path=Environment.getDataDirectory().getAbsolutePath();返回/data
获得内置SD卡路径:
public String getStorageDir(){
if(!(Environment.getExternalStorageState().equals(Environment.MEDIA_MOUNTED))){
return "";
}
File dirFile=Environment.getExternalStorageDirectory();
Log.d(TAG, dirFile.getAbsolutePath());
return dirFile.getAbsolutePath();
}
返回/storage/emulated/o
获得外置TF卡路径：
思路：通过linux中的mount命令。
public String getTFDir(){
String path="";
try {
InputStream ins=Runtime.getRuntime().exec("mount").getInputStream();
BufferedReader reader=new BufferedReader(new InputStreamReader(ins));
String line="";
while((line=reader.readLine())!=null){
if(line.contains("sdcard")){
if(line.contains("vfat")||line.contains("fuse")){
String split[]=line.split(" ");
path=split[1];
Log.d(TAG,path);
}
}
}
reader.close();
ins.close();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}finally{
}
return path;
}返回/storage/sdcard1这就是我们想要的路径。
获得可用空间
public static long getAvailableSize(String path){
try{
File base = new File(path);
StatFs stat = new StatFs(base.getPath());
long nAvailableCount = stat.getBlockSize() * ((long) stat.getAvailableBlocks());
return nAvailableCount;
}catch(Exception e){
e.printStackTrace();
}
return 0;
}返回bytes单位的大小。
