如何正确获得Android内外SD卡路径

/

获取手机自身内存路径

/

public static String getPhoneCardPath(){

return EnvironmentgetDataDirectory()getPath();

}

/

获取sd卡路径

双sd卡时，根据”设置“里面的数据存储位置选择，获得的是内置sd卡或外置sd卡

@return

/

public static String getNormalSDCardPath(){

return EnvironmentgetExternalStorageDirectory()getPath();

}

/

获取sd卡路径

双sd卡时，获得的是外置sd卡

@return

//获取当前路径，可用空间

public static long getAvailableSize(String path){

try{

File base = new File(path);

}

呃，一般原生系统貌似都没有集成文件管理器。不过不用你那么麻烦，你刷机应该是卡刷吧，刷机之前先在电脑里头把下载好的ES或RE文件管理器的安装包，放到下载好的刷机包里就是了，直接拖拽进去，不要改变原刷机包的属性等参数。

拖拽目录：system/app

public long getSDAllSize(){ //取得SD卡文件路径 File path = EnvironmentgetExternalStorageDirectory(); StatFs sf = new StatFs(pathgetPath()); //获取单个数据块的大小(Byte) long blockSize = sfgetBlockSize(); //获取所有数据块数 long allBlocks = sfgetBlockCount(); //返回SD卡大小 //return allBlocks blockSize; //单位Byte //return (allBlocks blockSize)/1024; //单位KB return (allBlocks blockSize)/1024/1024; //单位MB }
