I am trying to open a pdf file which is stored on a internal storage but not able to view it. Below is my code snippet to save file on internal storage.
try (FileOutputStream fos = openFileOutput("demo.pdf", Context.MODE_PRIVATE)) {
fos.write(inputStream.read(buffer));
}
Code to open pdf file:
File file = new File(getFilesDir(), "demo.pdf");
Uri fileUri= FileProvider.getUriForFile(getApplicationContext(), getPackageName() + ".opener.provider", file);
Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setDataAndType(photoURI, "application/pdf");
intent.addCategory(Intent.CATEGORY_OPENABLE);
intent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
startActivity(intent);
opener_path.xml:
<paths xmlns:android="http://schemas.android.com/apk/res/android">
<files-path name="files" path="." />
<cache-path name="cache" path="." />
<external-files-path name="external-files" path="." />
<external-cache-path name="external-cache" path="." />
<external-path name="external" path="." />
</paths>
In AndroidManifest.Xml
<provider
android:authorities="${applicationId}.opener.provider"
android:exported="false"
android:grantUriPermissions="true"
android:name="com.demo.fileopener2.FileProvider">
<meta-data android:name="android.support.FILE_PROVIDER_PATHS" android:resource="#xml/opener_paths" />
</provider>
Any help will be appreciated. Thank you

I'm trying to install apk programmatically in "Work Profile" mode (BYOD). But there is a problem which I cannot solve : No way to install an apk in android versions 7.0(24) and 7.1(25). A pop-up dialog appear with this message :
Your administrator doesn't allow installation of apps obtained from
unknown sources
Voila how I do :
val uri = FileProvider.getUriForFile(context,authority,File(filePath))
val openFileIntent = Intent(Intent.ACTION_VIEW)
openFileIntent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION)
openFileIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK)
openFileIntent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP)
openFileIntent.data = uri
context.startActivity(openFileIntent)
in Manifest :
<provider
android:name="androidx.core.content.FileProvider"
android:authorities="${applicationId}.provider"
android:exported="false"
android:grantUriPermissions="true"
tools:replace="android:authorities">
<meta-data
android:name="android.support.FILE_PROVIDER_PATHS"
android:resource="#xml/file_provider_paths"
tools:replace="android:resource" />
</provider>
And file_provider_paths.xml :
<?xml version="1.0" encoding="utf-8"?>
<paths>
<external-path
name="external"
path="." />
<external-files-path
name="external_files"
path="." />
<files-path
name="files"
path="." />
</paths>
This is how I found out the solution :
if (Build.VERSION.SDK_INT <= Build.VERSION_CODES.N) {
devicePolicyManager.setSecureSetting(
componentName,
Settings.Secure.INSTALL_NON_MARKET_APPS,
"1"
)
} else {
devicePolicyManager.addUserRestriction(componentName,
UserManager.DISALLOW_INSTALL_UNKNOWN_SOURCES)
}
This is my code block:
notificationIntent.setDataAndType(FileProvider.getUriForFile(
context,
"TrySomething",new File(context.getFilesDir().getAbsolutePath() + "/update_file")
),ANDROID_PACKAGE);
And this is my XML file:
<?xml version="1.0" encoding="utf-8"?>
<paths xmlns:android="http://schemas.android.com/apk/res/android">
<external-files-path name="myupdater" path="files/update_file"/>
</paths>
But i get this error:
java.lang.IllegalArgumentException: Failed to find configured root
that contains /data/data/com.example.trysomething/files/update_file
How can I fix it?
First Create Xml File inside src->xml folder Like
for example named file_paths_public.xml
<?xml version="1.0" encoding="utf-8"?>
<paths xmlns:android="http://schemas.android.com/apk/res/android">
<external-path
name="external_files"
path="." />
<root-path
name="external_files"
path="/storage/"/>
</paths>
then Add this Code in to your manifest file
<provider
android:name="android.support.v4.content.FileProvider"
android:authorities="<your app package>.provider"
android:exported="false"
android:grantUriPermissions="true">
<meta-data
android:name="android.support.FILE_PROVIDER_PATHS"
android:resource="#xml/file_paths_public" />
</provider>
now create one function that will support both api 26 and below device
that returns some valid uri
public static Uri getUriFromFile(Context theCtx, File theSrcPath) {
Uri requirdUri;
// Above Compile SDKversion: 25 -- Uri.fromFile Not working
// So we have to use Provider
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) {
requirdUri = FileProvider.getUriForFile(theCtx,
theCtx.getApplicationContext().getPackageName() + ".provider",
theSrcPath);
} else {
requirdUri = Uri.fromFile(theSrcPath);
}
return requirdUri;
}
now use this uri Whenever you want
like
File FilePath = Environment.getExternalStorageDirectory().toString()/update_file/<here your file name >
Uri shareImageUri = getUriFromFile(this, <your full file Path Add hear>)
Check if you have this in your manifest
<provider
android:name="android.support.v4.content.FileProvider"
android:authorities="${applicationId}.provider"
android:exported="false"
android:grantUriPermissions="true">
<meta-data
android:name="android.support.FILE_PROVIDER_PATHS"
android:resource="#xml/provider_paths"/>
</provider>
provider_paths:
<?xml version="1.0" encoding="utf-8"?>
<paths>
<external-path name="directory_name" path="."/>
</paths>
Get file URI as
Uri fileUri = FileProvider.getUriForFile(context, getApplicationContext().getPackageName() + ".provider", fileName(FILE))
Trying to open an image in the default gallery app. I can't resolve this issue following the steps:
My file path is /data/data/{applicationName}/cache/file.jpg
Intent:
Intent intent = new Intent(Intent.ACTION_VIEW);
File file = new File(filePath);
intent.setDataAndType(FileProvider.getUriForFile(this, getApplicationContext()
.getPackageName() + ".provider", file),"image/*");
intent.setFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
Manifest:
<provider
android:name="android.support.v4.content.FileProvider"
android:authorities="${applicationId}.provider"
android:exported="false"
android:grantUriPermissions="true">
<meta-data
android:name="android.support.FILE_PROVIDER_PATHS"
android:resource="#xml/provider_paths"/>
</provider>
provider_paths.xml
<?xml version="1.0" encoding="utf-8"?>
<paths>
<external-path
name="external_files"
path="." />
</paths>
I've tried changing the path and name in provider_paths but no luck.
Replace:
<external-path
name="external_files"
path="." />
with:
<cache-path name="external_files" />
as your path seems to be in getCacheDir().
I'm getting this exception when trying to use FileProvider:
Java.Lang.IllegalArgumentException: Unable to find configured root for content://com.abc/Android/data/com.abc/files/345345345.pdf Java.Lang.IllegalArgumentException
I guess my file_paths.xml configures the FileProvider with the wrong path. My code:
file_paths.xml:
<?xml version="1.0" encoding="UTF-8" ?>
<paths xmlns:android="http://schemas.android.com/apk/res/android">
<external-path path="." name="." />
<files-path path="com.abc/Android/data/com.abc/files/" name="files" />
</paths>
androidManifest.xml
<application android:label="#string/AppName" android:icon="#drawable/ic_launcher">
<meta-data android:name="com.google.android.gms.version" android:value="#integer/google_play_services_version" />
<provider android:name="android.support.v4.content.FileProvider" android:authorities="com.abc" android:exported="false" android:grantUriPermissions="true">
<meta-data android:name="android.support.FILE_PROVIDER_PATHS" android:resource="#xml/file_paths" />
</provider>
</application>
What values should I put in path and name in file_paths.xml, to expose the file with the content URI: content://com.abc/Android/data/com.abc/files/345345345.pdf?
my code which creates the URI:
File newFile = new File (Application.Context.FilesDir.AbsolutePath, filename);
Android.Net.Uri androidContentUri = FileProvider.GetUriForFile (Application.Context, Application.Context.PackageName, newFile);
System.Uri systemContentUri = SystemUri (androidContentUri);
return systemContentUri;
Your entry:
<files-path path="com.abc/Android/data/com.abc/files/" name="files" />
Should become:
<files-path path="files" name="files" />
Path in this case represents the files in the files/ subdirectory of your app's internal storage area.
This application private subdirectory is the same as the value returned:
Application.Context.FilesDir;
So the file location within your app is:
var path = Path.Combine(Application.Context.FilesDir.AbsolutePath, "files");
For file in Cache dir , I can add this in xml to set FileProvider
<cache-path
name="image"
path="image/"/>
But if I storage file in External Cache Dir,I cannot get external-cache-path tag or something like that to set FileProvider.And
<external-path
name="image_external"
path="cache/image/"/>
did not help ,too.
This is my Manifest file:
<provider
android:name="android.support.v4.content.FileProvider"
android:authorities="com.tizi.quanzi"
android:exported="false"
android:grantUriPermissions="true">
<meta-data
android:name="android.support.FILE_PROVIDER_PATHS"
android:resource="#xml/file_paths"/>
</provider>
This is the xml/file_paths file:
<?xml version="1.0" encoding="utf-8"?>
<paths>
<cache-path
name="image"
path="image/"/>
<external-path
name="image_external"
path="cache/image/"/>
</paths>
And this is my Code:
String RootPath = App.getApplication().getExternalCacheDir().getAbsolutePath();
String filePath = RootPath + "/image/" + fileName;
// done something there to save file
Intent shareIntent = new Intent();
Uri contentUri = FileProvider.getUriForFile(App.getApplication(),
App.getApplication().getPackageName(), new File(filePath));
App.getApplication().grantUriPermission(App.getApplication().getPackageName(),
contentUri, Intent.FLAG_GRANT_READ_URI_PERMISSION | Intent.FLAG_GRANT_WRITE_URI_PERMISSION);
shareIntent.setData(contentUri);
shareIntent.setFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION | Intent.FLAG_GRANT_WRITE_URI_PERMISSION);
shareIntent.setAction(Intent.ACTION_SEND);
shareIntent.putExtra(Intent.EXTRA_STREAM, contentUri);
shareIntent.setType("image/*");
activity.startActivity(Intent.createChooser(shareIntent, "share image"));
And this is the error infomation:

Update:
The way to go with the Support Library 24.2.0 and above is how #ashughes says in his answer.
On that version they added two new tags to the implementation of FileProvider.java to be able to reference the external files and cache directories.
private static final String TAG_EXTERNAL_FILES = "external-files-path";
private static final String TAG_EXTERNAL_CACHE = "external-cache-path";
If you want to dig more into it, you can take a look at the changes made on this commit.
Original answer:
I had the same problem. I took a look at the class FileProvider.java, and as you said, there is no tag for external cache dir, just the four below.
private static final String TAG_ROOT_PATH = "root-path";
private static final String TAG_FILES_PATH = "files-path";
private static final String TAG_CACHE_PATH = "cache-path";
private static final String TAG_EXTERNAL = "external-path";
What I do is to use the external-path tag. This tag will point to the root of the external directory not to the cache one. So you can either specify the rest of the path from there to the cache directory on path, or you can use a dot so it points to the root of the external directory.
<external-path
name="external_files"
path="."/>
When you were using
<external-path
name="image_external"
path="cache/image/"/>
The method getFileForUri was checking if the path of the file starts with /storage/emulated/0/cache/image/ which it doesn't, because the path of your file is /storage/emulated/0/Android/data/com.tizi.quanzi/cache/image/. And that's the reason you are getting the exception.
As of Support Library 24.2.0, you can use:
<external-cache-path name="name" path="path" />
See FileProvider docs for more details.
Following configuration works for me:
I use
<paths>
<external-cache-path name="external_files" path="."/>
<external-path name="external_files" path="."/>
</paths>
in my code.
and my provider looks like this
<provider
android:name="android.support.v4.content.FileProvider"
android:authorities="com.bqe.core.provider.CameraFilesProvider"
android:exported="false"
android:grantUriPermissions="true">
<meta-data
android:name="android.support.FILE_PROVIDER_PATHS"
android:resource="#xml/camera_files_provider_paths" />
my min sdk
minSdkVersion 21
