I thought it would be straightforward, but things turned out to be complicated. Google’s documentation on FileProvider proved to be confusing and lacking concrete examples. Nevertheless, I knew I had to use ContentProvider to tackle the issue.Use a content URI returned by getUriForFile() to get information about a file managed by the FileProvider. FileProvider reports the column names defined in : For more information, see .

java - Android: How to catch or prevent FileProvider

My application is composed of package A and package B and must use the same files. Why Google developpers do not offer this very simple possibility : say in manifest A that package B has access to files, and vice-versa in manifest B ?EDIT1: Android refuses to install an app if on the same android phone another app declares a content provider which has the same "authority" name. So this solution is not good.Deletes the file associated with the specified content URI, as returned by getUriForFile(). Notice that this method does not throw an java.io.IOException; you must check its return value.

You must define at least one unique authority. Android System keeps a list of all providers and it distinguishes them by authority. Authority defines the FileProvider just like the application ID defines an Android application. The name is a logical directory name (which enables multiple directories to be shared) and this is visible in the content://... URI that we looked at earlier.When the app requests the content, FileProvider actually implements the ContentProvider responsible for serving the content, so there’s nothing further that our app needs to do:In the previous series of articles we looked at DownloadManager and saw that DownloadManager actually handles the sharing of downloaded content with other apps. But what if we actually need to do this and we’re not using DownloadManager? A common case for such things would be if we either want to share content with other apps or, as in the example in the previous series, the content was in a format that our app didn’t support so we wanted to defer the displaying of that content to another app on the device which did support the content type – in the example this was PDF. In this article we’ll explore why this can be problematic and look at FileProvider which enables us to quite simply do exactly what we need to.

android:authorities=${applicationId}.fileprovider. android:exported=false. android:grantUriPermissions=true> <. We also need to add a new xml file to define the path where the file should be saved.

FileProvider is a special subclass of that facilitates secure sharing of files <external-cache-path name=name path=path />. Represents files in the root of your app's external cache area. The root path of this.. For example if name value is “share”, then the FileProvider uri should be something like content://< authority >/share/abc.png. This way the real local file path will not exposed to other apps.Next we create a new Intent with ACTION_VIEW and set this URI as the Intent data. Next we set the flag FLAG_GRANT_READ_URI_PERMISSION on the Intent and this will automatically grant read permission to whichever app gains responsibility to display the content.intent.setFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION); If you set grantUriPermissions value to false, it will throw SecurityException(“Provider must grant uri permissions”).

Share Files Using FileProvider on Android Infinu

  1. The MainActivity from the sample app needs to share some content which has been stored in the internal cache directory. I won’t bother listing the full source here and providing a full explanation as it is fairly straightforward. We’ll focus on how we can share that content.
  2. We are implementing share functionality with android.support.v4.content.FileProvider . It works fine on Google Android devices with Android 4.1 and up. On the Kindle HDX (Fire OS 4.5.5) the share dialog appears, but nothing happens when I select and app

  4. FileProvider is a special subclass of ContentProvider which allows sharing of files between application through content URI instead of file:// URI.
  5. If we continue thinking of a FileProvider as a locked room, then this attribute is used to give a temporary one-time key to an external app. This attribute allows you to securely share your app’s internal storage. All you have to do is add either FLAG_GRANT_READ_URI_PERMISSION or FLAG_GRANT_WRITE_URI_PERMISSION to the Intent that activates the component to open your app’s internal file. To use these flags set their value to true.

FileProvider - Styling Android


uri: A content URI for a file, as returned by getUriForFile().selection: Ignored. Set to null.selectionArgs: Ignored. Set to null.Each tag has two attributes, name and path, name attribute value is the path value in the FileProvider uri when it is accessed by other apps. The <cache-path> element indicates that the content is actually stored within the internal cache for the app. If we had stored the content somewhere else then we would need to use either <files-path> for internal app storage; <external-path> for public external storage; <external-files-path> for external app storage; or <external-cache-path> for external app cache storage. <external-files-path name=name path=path />. 对应Context#getExternalFilesDir(String) Context.getExternalFilesDir(null). <provider android:name=android.support.v4.content.FileProvider android:authorities..

  1. Before sharing your file, you’ll have to manually grant the permission (read and/or write), for all applications targeted with your intent. Indeed, you can’t know which one the user will choose to share the file with.
  2. There are a variety of ways to serve the content URI for a file to a client app. One common way is for the client app to start your app by calling , which sends an to your app to start an in your app. In response, your app can immediately return a content URI to the client app or present a user interface that allows the user to pick a file. In the latter case, once the user picks the file your app can return its content URI. In both cases, your app returns the content URI in an sent via .

1. FileProvider Benefits.

Android File Provider Setup You must also add a few additional configuration files to adhere to the new strict mode: The Android FileProvider now can detect permissions - internal / external storage can be controlled - KitKat+ does not require the permissions - corrected the FileProvider resource xml *. Added support for email attachments - support for a string path and native file types *. Added attachments to the sample..

Android has internal storage and external storage. External storage is not private and may not always be availale. You get the path to the external storage system via the Environment.getExternalStorageDirectory() method Return a content URI for a given java.io.File. Specific temporary permissions for the content URI can be set with , or added to an by calling and then ; in both cases, the applicable flags are and . A FileProvider can only return a content for file paths defined in their <paths> meta-data element. See the Class Overview for more information. <uses-permission-sdk-23 android:name=android.permission.WRITE_EXTERNAL_STORAGE />. We'll obviously need the camera permission, but we'll also need the To do this, we need to get a file path to that external pictures directory and then add a subdirectory to the path for our app's pictures In general, the Android System uses a specific URI scheme for ContentProviders. The scheme is defined as content://<authority>/<path> so the system will know which ContentProvider is requested by matching the URI’s authority with the ContentProvider’s authority. * FileProvider is a special subclass of {@link ContentProvider} that facilitates secure sharing. private static final String TAG_EXTERNAL = external-path * FileProvider reports the column names defined in {@link android.provider.OpenableColumns

So what’s the alternative? The standard mechanism supported by Android is to define a ContentProvider which can expose content using a content://... URI, and the app sharing the content (i.e. our app) retains the responsibility for how and where the content is stored. Anyone who has ever implemented a ContentProvider will be aware that they can require a bit of work to implement. However, there is a simpler way: FileProvider.<provider android:authorities="< your provider authority >" android:name="android.support.v4.content.FileProvider" android:exported="false" android:grantUriPermissions="true"> <meta-data android:name="android.support.FILE_PROVIDER_PATHS" android:resource="@xml/shared_file_paths" /> </provider> FileProvider Attributes Explain.The default FileProvider implementation does not need to be initialized. If you want to override this method, you must provide your own subclass of FileProvider.

That’s because I have multiple flavors in the project and they can be installed on the device at the same time. Android System won’t let you install multiple applications with the same FileProvider so each flavor needs an unique authority.

The most obvious place for us to store content is in the app’s private storage area (using Context#openFileOutput()), or possibly the internal cache (using Context#getCacheDir()). The one aspect that both of these locations share is that they are only accessible to our app. While this may be good for security, it poses a problem if we wish to defer the displaying of the content to another app, such as with our PDF example. The obvious way to overcome this would be to use external storage using, for example but not limited to, Environment#getExternalStorageDirectory() or Environment#getDownloadCacheDirectory().

Mobile App Development & Android Projects for €8 - €30. I have a problem creating File object from the file path which is obtained from video recorder using a FileProvider. When I set the path of the VideoView where the recorded video should be previewe It is important for security reasons that we don’t export the provider hence android:exported="false". Although this may seem counter intuitive, we don’t want other apps directly accessing this ContentProvider – only via the OS which can access the provider without it being exported.Use a content URI returned by getUriForFile() to get information about a file managed by the FileProvider.

  5. The <provider> element can also have <grant-uri-permission> subelements. The only difference being that by using the attribute you can share anything inside your app’s internal storage, while subelements allow you to choose a specific data subset for sharing. To use subelements instead, set the value to false.
  6. The authorities attribute is what gets registered with the OS in order for it to identify this app as being the ContentProvider for that specific content. When we looked at the differences between the two types of URI this clearly identified our app, so it is usual to use the package name of the app here.

Android 适配 - FileProvider - 掘金 Path 节点里面的 path 属

Its nice exmaple. After going through FileProvider multiple examples I would like to know that: catgetExternalFilesDir() – stores in Internal Storage (wont require to ask WRITE permission at runtime) getExternalStoragePublicDirectory() – stores in SD card (that case needed to ask WRITE permission at runtime ) Is it correct? If yes then is it optional in above example to ask for WRITE permission at runtime Thanks

The base folder is context.getFilesDir() --> <files-path name="internal_files" path="" /> <!-- Share folder under internal cache folder. The base folder is context.getCacheDir() --> <cache-path name="internal_cache" path="" /> <!-- Share folder under public external storage folder.The base folder is Environment.getExternalStorageDirectory()--> <external-path name="external" path="Android/data/com.dev2qa.example/cache/" /> <!-- Share folder under app specific external file folder.The base folder is context.getExternalFilesDirs()--> <external-files-path name="external_files" path="" /> <!-- Share folder under app specific external cache folder.The base folder is context.getExternalCacheDirs()--> <external-cache-path name="external_cache" path="" /> </paths> From above example, we can see that you can share both root, internal, external folders in android.
