How do I write data to the SD card in Android via a StorageVolume?



I am desperately trying to write data to the SD card with my app. I am attempting to use the StorageVolume class to do this, but I am having lots of trouble.



This is what I have:


StorageManager storageManager = (StorageManager)context.getSystemService(STORAGE_SERVICE);
List<StorageVolume> storageVolumeList = storageManager.getStorageVolumes();
for(StorageVolume volume : storageVolumeList)
if(volume.getDescription(context).equalsIgnoreCase("sd card"))
Intent write_to_sd_card_intent = volume.createAccessIntent(Environment.DIRECTORY_DOCUMENTS);
if(write_to_sd_card_intent != null)

context.startActivityForResult(write_to_sd_card_intent, Constants.WRITE_TO_SD_CARD_REQUEST_CODE);





When I do this, it does ask my permission to write to that location, which is good, but I don't know what to do next. I looked at this article, but it doesn't say what to do after the startActivityForResult().


startActivityForResult()



I don't believe I can use the same procedures for a normal intent, as volume.createAccessIntent() creates an intent differently than a "normal" intent, because you are not passing the next activity into the method parameter.


volume.createAccessIntent()



Also, I don't see a way to use a StorageVolume to get a path to write my data to.

Any suggestions?



As an FYI, I have tried all of the Android approved methods of writing to the SD card with no luck. See my previous post HERE





FYI, an Intent on Android is just an abstract description of an operation to be performed. It can sure be used to start another Activity but it's far from its sole purpose.

@shkschneider I don't know what you are trying to tell me.

I'm just noticing, regarding your comment about a "normal intent", that an Intent has many more usages behind starting an Activity. The italic part was from Google ^^

Activity





@shkschneider I meant "normal" as in the way the Intent is created.

Firebase Auth - with Email and Password - Check user already registered

Clash Royale CLAN TAG #URR8PPP Firebase Auth - with Email and Password - Check user already registered I want to check when a user attempts to signup with createUserWithEmailAndPassword() in Firebase user Authentication method, this user is already registered with my app. createUserWithEmailAndPassword() 8 Answers 8 To detect whether a user with that email address already exists, you can detect when the call to createUserWithEmailAndPassword () fails with auth/email-already-in-use . I see that @Srinivasan just posted an answer for this. createUserWithEmailAndPassword () auth/email-already-in-use Alternatively, you can detect that an email address is already used by calling fetchSignInMethodsForEmail() (previous called fetchProvidersForEmail() ). fetchSignInMethodsForEmail() fetchProvidersForEmail() When the user trying to create an user with same email address, the task response will be "Response: The email address is already in use by another account." mFirebas

Clash Royale CLAN TAG #URR8PPP Dynamically update html content plain JS So I have a script bound in my index.html, which literally has to fetch an array of jsons from an api, then dynamically update my page when get response. But as a result I'm getting an as the only update of my page. here is my script fetch(url) .then((resp) => resp.json()) .then((resp) => resp.results.forEach(item => fetch(item.url) .then((response)=> response.json()) .then((response) => pokeArr.push(response)) .catch(console.log) ) ).catch(console.log) const filler = () => if(!pokeArr) return 0 pokeArr.map((i,j)=> return `<tr>$i.name</tr>` ) const pokeindex = () => document.getElementById('a').appendChild(document.createElement(filler())) pokeindex() When I'm consoling it, I can see in the console all the responses I get, so I'm at least doing the fetching part right. What's parberakan ? What's pokeArr ? – T.J. Crowder Aug 8 at 12

How to determine optimal route across keyboard

Clash Royale CLAN TAG #URR8PPP How to determine optimal route across keyboard I'm trying to automate the typing process in a video game. Players are given an on-screen QWERTY keyboard layout that they can navigate with the control stick (up, down, left, right) in order to select a letter to type. I was wondering if there was a module for Python (or some other resource I could explore) that would help my program find a path across the keyboard as it types each letter in a given message. In other words, if the first letter typed was "A" and the next letter was "B", the module would know that the program should move 1 space down on the keyboard and 4 spaces to the right. Currently, I have the program resetting to the "G" key after each letter is typed (allowing me to use fixed-directions as the program parses each character in the desired message). As you can imagine, this is quite inefficient and defeats the purpose of automating the typing in the fir
