sample code for the above issue (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 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);
    
   });

Hello, This is working for me with Android 6.0.1.device. On first run I am allowing the Camera and Storage permission that pops up right after the app opens. Than when the button is clicked the alert dialog opens with "this is my sample text" alert. From now on clicking on the button shows the alert. If I close the app and reopen, this time there is no permission asked to allowed and clicking on the button shows the alert. If I close the app and remove the permissions for that app from the device application manager. I can open the app and the permission dialog pops up now after app opens. If I allow them, than the button click shows the alert text. I am testing with SDK 6.0.4.GA. Make sure you are allowing the permissions on first run before clicking on the button.

Hello, can you try this with the write permission?

   
   var storePermission = "android.permission.WRITE_EXTERNAL_STORAGE";
   
   var storagePermission = "android.permission.READ_EXTERNAL_STORAGE";
   
   var hasStorePermission = Ti.Android.hasPermission(storePermission);
   
   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 (!hasStorePermission) {
   
       permissionsToRequest.push(storePermission);
   
   }
   
   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);
   
   
   });

Use this in tiapp.xml

   <manifest>
   
               <uses-permission android:name="android.permission.INTERNET"/>
   
               <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
   
               <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"/>
   
               <application android:hardwareAccelerated="true" android:largeHeap="true"/>
   
   </manifest>

Hi, I have tested following test code with latest SDK 6.0.4.GA on android 6.0.1(HTC one m 8). It's working as expected. On the first run, I am allowing the storage permission that pops up right after the app opens. Then when the button is clicked the alert dialog opens with "this is my sample text" alert. If I close the app and reopen, this time there is no permission asked to allowed and clicking on the button shows the alert.

   var storePermission = "android.permission.WRITE_EXTERNAL_STORAGE";
    
   var storagePermission = "android.permission.READ_EXTERNAL_STORAGE";
    
   var hasStorePermission = Ti.Android.hasPermission(storePermission);
    
   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 (!hasStorePermission) {
    
       permissionsToRequest.push(storePermission);
    
   }
    
   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);
    
    
   });
