If you want to Get Uri path from String File path .this code will be worked also in androidQ.
<pre><code>String outputFile = context.getExternalFilesDir(&quot;DirName&quot;) + &quot;/fileName.extension&quot;;

 File file = new File(outputFile);
 Log.e(&quot;OutPutFile&quot;,outputFile);
 Uri uri = FileProvider.getUriForFile(Activity.this,
 BuildConfig.APPLICATION_ID + &quot;.provider&quot;,file);
</code></pre>
declare provider in application Tag manifest
<pre><code>&lt;provider
 android:name=&quot;androidx.core.content.FileProvider&quot;
 android:authorities=&quot;${applicationId}.provider&quot;
 android:exported=&quot;false&quot;
 android:grantUriPermissions=&quot;true&quot;&gt;
 &lt;meta-data
 android:name=&quot;android.support.FILE_PROVIDER_PATHS&quot;
 android:resource=&quot;@xml/provider_paths&quot; /&gt;
 &lt;/provider&gt;
</code></pre>
under res -&gt; xml -&gt;provider_paths.xml
<pre><code>&lt;paths&gt;
 &lt;external-path name=&quot;external_files&quot; path=&quot;.&quot;/&gt;
&lt;/paths&gt;
</code></pre>

I have an app where I capture a video using the camera. I can get the video's file path, but I need it as a Uri.

The file path I'm getting:

<pre><code>/storage/emulated/0/DCIM/Camera/20141219_133139.mp4
</code></pre>

What I need is like this:

<pre><code>content//media/external/video/media/18576.
</code></pre>

This is my code.

<pre><code>protected void onActivityResult(int requestCode, int resultCode, Intent data) {
 // if the result is capturing Image

 if (requestCode == CAMERA_CAPTURE_VIDEO_REQUEST_CODE) {
 if (resultCode == RESULT_OK) {
 // video successfully recorded
 // preview the recorded video
 // selectedImageUri = data.getData();
 // Uri selectedImage = data.getData();
 previewVideo();

 tv1.setText(String.valueOf((fileUri.getPath())));
 String bedroom=String.valueOf((fileUri.getPath()));
 Intent i = new Intent();
 i.putExtra(bhk1.BEDROOM2, bedroom);
 setResult(RESULT_OK,i); 
 btnRecordVideo.setText("ReTake Video");

 } else if (resultCode == RESULT_CANCELED) {
 // user cancelled recording
 Toast.makeText(getApplicationContext(),
 "User cancelled video recording", Toast.LENGTH_SHORT)
 .show();
 } else {
 // failed to record video
 Toast.makeText(getApplicationContext(),
 "Sorry! Failed to record video", Toast.LENGTH_SHORT)
 .show();
 }
 }
 }
</code></pre>

I need a Uri from the String variable <code>bedroom</code>.
