URI for your PDF file and pass it through the Intent Open PDF

 The error message you're seeing (FileUriExposedException) occurs because starting from Android 7.0 (API level 24), file:// URIs are no longer allowed to be passed to other applications via Intent. This is a security measure to prevent exposing sensitive files to other apps.

Step 1 :

Go to app -> src -> main -> AndroidManifest.xml.

Step 2:

Copy following code:

2. In your AndroidManifest.xml file, ensure that you have defined the FileProvider correctly:
<provider android:name="androidx.core.content.FileProvider" android:authorities="com.example.meyepro.fileprovider" android:exported="false" android:grantUriPermissions="true"> <meta-data android:name="android.support.FILE_PROVIDER_PATHS" android:resource="@xml/file_paths" /> </provider>

3. Verify that you have created the file_paths.xml file correctly in the res/xml directory with the following content:

<paths>
    <external-path name="external_files" path="." />
</paths>

To resolve this issue, you can use a FileProvider to generate a content URI for your PDF file and pass it through the Intent. Here's how you can modify your code to use FileProvider:

 // Assuming your PDF file path is stored in the variable 'pdfFilePath'

File   file = new File(String.valueOf(Environment.getExternalStorageDirectory()), "muzamil.pdf");

// Generate a content URI using FileProvider
Uri contentUri = FileProvider.getUriForFile(getActivity(), "com.example.meyepro.fileprovider", file);
Toast.makeText(this, ""+getContext().getPackageName() + ".fileprovider", Toast.LENGTH_SHORT).show();
// Create an 'Intent' to view the PDF
Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setDataAndType(contentUri, "application/pdf");
intent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION); // Grant read permission to the receiving app

// Start the activity with the 'Intent'
try {
    startActivity(intent);
} catch (ActivityNotFoundException e) {
    Toast.makeText(getContext(), "No PDF viewer application found.", Toast.LENGTH_SHORT).show();
}

Different Way open file

add this two line in onCreate

StrictMode.VmPolicy.Builder builder = new StrictMode.VmPolicy.Builder();
StrictMode.setVmPolicy(builder.build());

Share method

File dir = new File(Environment.getExternalStorageDirectory(), "ColorStory");
File file = new File(dir, "0.pdf");

Intent openPdfIntent = new Intent(Intent.ACTION_VIEW);
openPdfIntent.setDataAndType(Uri.parse("file://" + file), "application/pdf");
openPdfIntent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
startActivity(openPdfIntent);

Different Way open file

In the Java code, we create an Uri object based on the SDK version. If the SDK version is below 24, we use Uri.fromFile(file). Otherwise, we use Uri.parse(file.getPath()) to get the URI of the file.

Then, we create an Intent with the ACTION_SEND action and set the appropriate MIME type for a PDF file. We add the URI as an extra with Intent.EXTRA_STREAM. Additionally, we set the subject and text for the sharing message.

Finally, we use Intent.createChooser to create a chooser dialog and start the activity with the chosen intent.

Please note that you may need to handle runtime permissions and file access based on your specific use case and target SDK version.

File dir = new File(Environment.getExternalStorageDirectory(), "ColorStory");
File file = new File(dir, "0.pdf");

Uri uri;
if (Build.VERSION.SDK_INT < 24) {
    uri = Uri.fromFile(file);
} else {
    uri = Uri.parse(file.getPath());
}

Intent shareIntent = new Intent();
shareIntent.setAction(Intent.ACTION_SEND);
shareIntent.setType("application/pdf");
shareIntent.putExtra(Intent.EXTRA_STREAM, uri);
shareIntent.putExtra(Intent.EXTRA_SUBJECT, "Purchase Bill...");
shareIntent.putExtra(Intent.EXTRA_TEXT, "Sharing Bill purchase items...");

startActivity(Intent.createChooser(shareIntent, "Share Via"));
