Intent.action_send Not Working On Oreo

I am developing a custom camera application which captures a picture and stores it in the gallery. When I share that image using Intent.ACTION_SEND, it works absolutely fine on all

Solution 1:

If targetSdkVersion is higher than 24, then FileProvider is used to grant access.

Create an xml file(Path: res\xml) provider_paths.xml

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

Add a Provider in AndroidManifest.xml under

<providerandroid:name="android.support.v4.content.FileProvider"android:authorities="${applicationId}.provider"android:exported="false"android:grantUriPermissions="true"><meta-dataandroid:name="android.support.FILE_PROVIDER_PATHS"android:resource="@xml/provider_paths"/></provider>

and replace

Uriuri= Uri.fromFile(fileImagePath);

to

Uriuri= FileProvider.getUriForFile(MainActivity.this, BuildConfig.APPLICATION_ID + ".provider",fileImagePath);

and you are done.

Solution 2:

Use File Provider for getting IMAGE URI and add flags to the intent... follow these steps carefully.. android.os.FileUriExposedException: file:///storage/emulated/0/test.txt exposed beyond app through Intent.getData() This update has been done since nougat..
