问题描述

下面是我的code出口SD卡上的联系人VCF文件。但我找不到SD卡VCF。
帮我看看那个。在此先感谢

code得到VCF文件:

 公共静态无效getVCF(){ 最后弦乐vfile =POContactsRestore.vcf; 。光标手机= mContext.getContentResolver()查询(ContactsContract.CommonDataKinds.Phone.CONTENT_URI,NULL,NULL,NULL,NULL); phones.moveToFirst();
   的for(int i = 0; I< phones.getCount();我++)
   {
      串lookupKey = phones.getString(phones.getColumnIndex(ContactsContract.Contacts.LOOKUP_KEY));
     URI URI = Uri.withAppendedPath(ContactsContract.Contacts.CONTENT_VCARD_URI,lookupKey);    AssetFileDescriptor的fd;
     尝试
     {
         FD = mContext.getContentResolver()openAssetFileDescriptor(URI,R)。
         FIS的FileInputStream = fd.createInputStream();
         字节[] buf中=新的字节[(INT)fd.getDeclaredLength()];
         fis.read(BUF);
         字符串电子名片=新的String(BUF);
         字符串路径= Environment.getExternalStorageDirectory()的toString()+文件分割符+ vfile。
         FileOutputStream中mFileOutputStream =新的FileOutputStream(路径,真实);
                    mFileOutputStream.write(VCard.toString()的getBytes());
         phones.moveToNext();
         Log.d(电子名片,电子名片);
     }
     赶上(例外E1)
     {
          // TODO自动生成catch块
          e1.printStackTrace();
     } }
}

清单

解决方案

尝试:

 字符串路径= Environment.getExternalStorageDirectory()getAbsolutePath()+文件分割符+ vfile。

Here is my code to export contacts to VCF file on SDcard. But i can't find vcf on SDCard. Help me find that. Thanks in advance

Code to get VCF file:

public static void getVCF() 

{

 final String vfile = "POContactsRestore.vcf";

 Cursor phones = mContext.getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null,null, null, null);

 phones.moveToFirst();
   for(int i =0;i<phones.getCount();i++)
   {
      String lookupKey =  phones.getString(phones.getColumnIndex(ContactsContract.Contacts.LOOKUP_KEY));
     Uri uri = Uri.withAppendedPath(ContactsContract.Contacts.CONTENT_VCARD_URI, lookupKey);

    AssetFileDescriptor fd;
     try 
     {
         fd = mContext.getContentResolver().openAssetFileDescriptor(uri, "r");
         FileInputStream fis = fd.createInputStream();
         byte[] buf = new byte[(int) fd.getDeclaredLength()];
         fis.read(buf);
         String VCard = new String(buf);
         String path = Environment.getExternalStorageDirectory().toString() + File.separator + vfile;
         FileOutputStream mFileOutputStream = new FileOutputStream(path, true);
                    mFileOutputStream.write(VCard.toString().getBytes());           
         phones.moveToNext();                           
         Log.d("Vcard",  VCard);
     } 
     catch (Exception e1) 
     {
          // TODO Auto-generated catch block
          e1.printStackTrace();
     }

 }
}

Manifest // permisson

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

解决方案

try:

    String path = Environment.getExternalStorageDirectory().getAbsolutePath() + file.separator + vfile;
