Sample Code ============== app.js ------------

   var cameraPermission = "android.permission.CAMERA";
   var storagePermission = "android.permission.READ_EXTERNAL_STORAGE";
   var hasCameraPermission = Ti.Android.hasPermission(cameraPermission);
   var hasStoragePermission = Ti.Android.hasPermission(storagePermission);
   var permissionsToRequest = [];
   
   
   
   var win = Ti.UI.createWindow({
           title: 'mywin',
           backgroundColor: '#fff',
           width : Ti.UI.FILL,
           height : Ti.UI.FILL
   });
   
   win.open();
   
   
   if (!hasCameraPermission) {
       permissionsToRequest.push(cameraPermission);
   }
   if (!hasStoragePermission) {
       permissionsToRequest.push(storagePermission);
   }
   if (permissionsToRequest.length > 0) {
       Ti.Android.requestPermissions(permissionsToRequest, function(e) {
           if (e.success) {
               Ti.API.info("SUCCESS");
           } else {
               Ti.API.info("ERROR: " + e.error);
           }
       });
   }
   
   
   		var localPath = Ti.Filesystem.getFile(Ti.Filesystem.externalStorageDirectory).nativePath;
   									
   					var sampletxtvar = Ti.Filesystem.getFile(localPath, "sample.txt");
   					sampletxtvar.write("this is my sample text");
   
   					var content = "";		
   
   					if (sampletxtvar.exists()) {
   								content = nomediatxt.read().text;
   								alert("Content is ::: " +content);
   					}

=============== tiapp.xml -------------

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

Hello, My understanding is you are trying to access the external storage and write there without allowing the permission during runtime. So, what you need to do is, you need to put your code of writing inside a button eventlistner and on window open you allow the access and click on the button to write and so forth. Now, your code works on second run on my device cause i allowed the permission on first run and the app remembers it. Thanks.

Hi , thanks! it's working on second run, I am able to read and write the file in external storage. but *how can I make it work on first run*. because even after I had read/write file on button click eventListener still not working first run and it throws error while click on button >>>TiFileProxy: java.io.FileNotFoundException: /storage/emulated/0/com.example.sample/sample.txt: open failed: EACCES (Permission denied) NOTE : I have also added requestPermission under window.open event

Hello, Take a look at my code below.

   var cameraPermission = "android.permission.CAMERA";
   
   var storagePermission = "android.permission.READ_EXTERNAL_STORAGE";
   
   var hasCameraPermission = Ti.Android.hasPermission(cameraPermission);
   
   var hasStoragePermission = Ti.Android.hasPermission(storagePermission);
   
   var permissionsToRequest = [];
   
   var win = Ti.UI.createWindow({
   
       title : 'mywin',
   
       backgroundColor : '#fff',
   
       width : Ti.UI.FILL,
   
       height : Ti.UI.FILL
   
   });
   
   win.open();
   
   if (!hasCameraPermission) {
   
       permissionsToRequest.push(cameraPermission);
   
   }
   
   if (!hasStoragePermission) {
   
       permissionsToRequest.push(storagePermission);
   
   }
   
   if (permissionsToRequest.length > 0) {
   
       Ti.Android.requestPermissions(permissionsToRequest, function(e) {
   
           if (e.success) {
   
               Ti.API.info("SUCCESS");
   
           } else {
   
               Ti.API.info("ERROR: " + e.error);
   
           }
   
       });
   
   }
   
   var btn1 = Ti.UI.createButton({
   
       title : 'Write',
       top : 60
   
   });
   win.add(btn1);
   
   btn1.addEventListener('click', function() {
       var localPath = Ti.Filesystem.getFile(Ti.Filesystem.externalStorageDirectory).nativePath;
   
       var sampletxtvar = Ti.Filesystem.getFile(localPath, "sample.txt");
   
       sampletxtvar.write("this is my sample text");
   
       alert(sampletxtvar.read().text);
   
   });

this works on first run. Thanks.
