TC75 Android 4.4.2 : Problem with writing file on sd card

Hi,

 

I'm trying to write on removable storage , But getting IOException

 

java.io.FileNotFoundException: /storage/extSdCard/PWC/Images/IMG_20151210_113150.jpg: open failed: EACCES (Permission denied)

at libcore.io.IoBridge.open(IoBridge.java:409)

 

Caused by: libcore.io.ErrnoException: open failed: EACCES (Permission denied)

at libcore.io.Posix.open(Native Method)

at libcore.io.BlockGuardOs.open(BlockGuardOs.java:110)

at libcore.io.IoBridge.open(IoBridge.java:393)

 

The line I used to write is

 

try{

 

FileInputStream myinput = new FileInputStream(from);

 

String outfilename = to;

 

OutputStream myoutput = new FileOutputStream(outfilename);

// transfer byte to inputfile to outputfile

byte[] buffer = new byte[1024];

int length;

while ((length = myinput.read(buffer)) > 0) {

myoutput.write(buffer, 0, length);

}

 

//Close the streams

myoutput.flush();

myoutput.close();

myinput.close();

 

return true;

}

catch ( IOException e){

e.printStackTrace();

return false;

}

 

from and to is a valid file location.

 

If I use Internal and Emulated External file path , Above is working fine.

If I use secondary or removable storage file path , getting issue.

 

The path gives canWrite as true.

 

Testing on Android 4.4.2 Samsung SM-G350E and Zebra TC75

 

Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);

intent.putExtra(MediaStore.EXTRA_OUTPUT, imageUri); // set the image file name
startActivityForResult(intent, 300);

 

Using the above code is working and writing the image on samsung,

but failed to write on zebra , the save button with 'tick' icon has no response.
