我有一个小FileExplorer在我的应用程序，我想他启动文件夹，它是目前使用的defautl相机研究。有没有办法让这条道路？ 我trye​​d：

  Environment.getExternalStoragePublicDirectory（Environment.DIRECTORY_PICTURES）.getAbsolutePath（））;
 

但是，这不返回到/ mnt / SD卡/图片和我的相机是存储在MNT / SD卡/ ext_sd / DCIM / 100MEDIA /

PS： 我不知道如何启动摄像头与一个特定的文件夹来存储照片，这不是我在寻找，

解决方案

 的String []投影=新String[]{MediaStore.Images.ImageColumns._ID,MediaStore.Images.ImageColumns.DATA,MediaStore.Images.ImageColumns.BUCKET_DISPLAY_NAME,MediaStore.Images.ImageColumns.DATE_TAKEN,MediaStore.Images.ImageColumns.MIME_TYPE};
最后光标光标= managedQuery（MediaStore.Images.Media.EXTERNAL_CONTENT_URI，投影，NULL，NULL，MediaStore.Images.ImageColumns.DATE_TAKEN +降序）;
如果（光标！= NULL）{
    cursor.moveToFirst（）;
    //你都会在这里找到最后拍摄的照片
    //根据博扬Radivojevic轰炸机评论不关闭游标（他是对的^^）
    //cursor.close（）;
}
 

I have a small FileExplorer in my app and i want him to start in the folder, which is currently used by the defautl camera. Is there a way to get this path? I tryed:

Environment.getExternalStoragePublicDirectory (Environment.DIRECTORY_PICTURES).getAbsolutePath());

But this do not returns "/mnt/sdcard/Pictures" and my Camera is storing in "mnt/sdcard/ext_sd/DCIM/100MEDIA/"

PS: I do know how to start the camera with a specific folder for storing the pictures, that's not what i'm searching for,

解决方案

String[] projection = new String[]{MediaStore.Images.ImageColumns._ID,MediaStore.Images.ImageColumns.DATA,MediaStore.Images.ImageColumns.BUCKET_DISPLAY_NAME,MediaStore.Images.ImageColumns.DATE_TAKEN,MediaStore.Images.ImageColumns.MIME_TYPE};     
final Cursor cursor = managedQuery(MediaStore.Images.Media.EXTERNAL_CONTENT_URI,projection, null, null, MediaStore.Images.ImageColumns.DATE_TAKEN + " DESC"); 
if(cursor != null){
    cursor.moveToFirst();
    // you will find the last taken picture here
    // according to Bojan Radivojevic Bomber comment do not close the cursor (he is right ^^)
    //cursor.close();
}
