Description

*Steps to reproduce:* 1. Add the code below to controllers/index.js:

function doClick(e) {
        var file = Ti.Filesystem.getFile(Ti.Filesystem.externalStorageDirectory, "test.txt");
	file.write("i love writing to files");
}

$.index.open();

2. Launch the app. 3. Click on the "Hello, World" text. *Results:*

This has to do with Storage permission required in Android 6.0. Workaround for now is to write it this way:-

      if (Ti.Media.hasCameraPermissions()) {
          var f = Ti.Filesystem.getFile(Ti.Filesystem.externalStorageDirectory, "tests.txt");
          f.write('writing to the file would be enough to create it');
      } else { 
          Ti.Media.requestCameraPermissions(function(e) {
                   if (e.success === true) {
                       var f = Ti.Filesystem.getFile(Ti.Filesystem.externalStorageDirectory, "tests.txt");
                       f.write('writing to the file would be enough to create it');
                   } else {
                       alert("Access denied, error: " + e.error);
                   }
          });
      }

This will provide the storage permission needed.

https://github.com/gimdongwoo/Ti-Android-RequestStoragePermission this plugin should request only the storage permission without the camera permission.

Should be fixed by this PR: https://github.com/appcelerator/titanium_mobile/pull/7948 You can use:

   var storagePermission = "android.permission.READ_EXTERNAL_STORAGE";
   var hasStoragePerm = Ti.Android.hasPermission(storagePermission);
   var permissionsToRequest = [];
   if (!hasStoragePerm) {
       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);
           }
       });
   }
