android.os.FileUriExposedException: file:///storage/emulated/0/Pictures/picFolder/1.jpg exposed beyond app through ClipData.Item.getUri()

Question

I am trying to take a photo from the phone\'s camera using this code:

activity_main.xml:

Answer 1

If your targetSdkVersion >= 24, then we have to use FileProvider class to give access to the particular file or folder to make them accessible for other apps.

1) First Add a FileProvider tag in AndroidManifest.xml under tag as below:

2) Then create a provider_paths.xml file in res/xml folder. Folder may be needed to created if it doesn't exist.

3) Now edit your activity class file as below:

Uri outputFileUri = Uri.fromFile(newfile);

to

Uri outputFileUri = FileProvider.getUriForFile(MainActivity.this, BuildConfig.APPLICATION_ID, newfile);

UPDATE #1

Update your MainActivity.java with this:
