To create new xml file on SD card I am using following code
String strFileName = Environment.getExternalStorageDirectory()+"/" +
"temp.xml";
try{
if(!lXmlfile.exists())
{
lXmlfile.createNewFile();
}
}catch(IOException e){
Log.e("IOException", e.toString());
return
null;
}
Above code giving me IO exception Permission denied. Although I have
added permission in AndroidManifest.xml
like:
<uses-permission
android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
still , can not create file. where am I going wrong? how can I test
this on emulator (create file on which path?) .Pls help its urgent.
One more question: Is user defined content provider is the best way to
complete this requirement(saving and retrieving form data that also
contains image). Pls share.
Regards
