Answer 1

    <provider
        android:name="androidx.core.content.FileProvider"
        android:authorities="${applicationId}.fileprovider"
        android:exported="false"
        android:grantUriPermissions="true">
        <meta-data
            android:name="android.support.FILE_PROVIDER_PATHS"
            android:resource="@xml/file_paths"></meta-data>
    </provider>

This is my provider declaration, the value of ${applicationId} is "com.limxtop.research", make sure that the name of authorities is the same with that of the codes below.

            // Create the file where the photo should save.
            File file = null;
            try {
                file = createImageFile();
            } catch (IOException e) {
                break;
            }
            // The second parameter is the name of authorities.
            Uri uri = FileProvider.getUriForFile(this,
                    "com.limxtop.research.fileprovider", file);
            intent.putExtra(MediaStore.EXTRA_OUTPUT, uri);
            intent.setFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION
                    | Intent.FLAG_GRANT_WRITE_URI_PERMISSION);
            startActivityForResult(intent, fullSizeRequestCode);

So, maybe your codes post here is not complete, there you should pass "my.package.name.fileprovider" as parameter some where.

Answer 2

Its fileprovider and not provider

android:authorities="${applicationId}.fileprovider"

Answer 3

I just removed the '$' from android:authorities="${applicationId}.provider" and it works like a charm now.

Answer 4

First write the following tag in manifest under the Tag

 <provider
            android:name="androidx.core.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>

Then Create a xml folder in res and create a file names: provide+paths.xml and then copy paste the code:

<?xml version="1.0" encoding="utf-8"?>
<paths xmlns:android="http://schemas.android.com/apk/res/android">
    <external-path
        name="external_files"
        path="." />
</paths>

and now most developer mistake in programs to create File in program then we will use:

FileProvider.getUriForFile(Objects.requireNonNull(getApplicationContext()),
                    BuildConfig.APPLICATION_ID + ".provider", file);

Hope this will work for yor !!!

Answer 5

{applicationId} == com.companyName.application append ".provider"

which will be == com.example.test.provider

in xml authorities:com.example.test.provider

in activity Uri mPath = FileProvider.getUriForFile(this, "com.example.example.provider", imageFile);

Answer 6

The problem here is, you use the class name .provider for authorities in manifest and use .fileprovider class name in java code.

 <provider
        android:name="androidx.core.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_app" />
    </provider>

Just rename fileprovider to provider
