My Quick Find Gallery (Part 5 - Share, Delete and Update Image)
12) Share Image
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.
Steps to replace file:// URI with content:// URI:
i) Add a FileProvider <provider> tag in AndroidManifest.xml under <application> tag:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
...
<application
...
<provider
android:name="android.support.v4.content.FileProvider"
android:authorities="com.myfileprovider"
android:exported="false"
android:grantUriPermissions="true">
<meta-data
android:name="android.support.FILE_PROVIDER_PATHS"
android:resource="@xml/file_provider_paths" />
</provider>
</application>
</manifest>
ii) Then create a file_provider_paths.xml file in res/xml folder:
<paths xmlns:android="http://schemas.android.com/apk/res/android">
<external-path name="share" path="/" />
</paths>
iii) ShowPhoto.java
@Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case R.id.action_share:
File file = new File(searchFilesPath.get(selectedImagePosition));
Intent shareIntent = new Intent(Intent.ACTION_SEND);
Uri picUri = FileProvider.getUriForFile(this, "com.myfileprovider", file);
shareIntent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
shareIntent.setType("image/*");
shareIntent.putExtra(Intent.EXTRA_STREAM, picUri);
startActivity(Intent.createChooser(shareIntent, "Share with"));
break;
default:
break;
}
return true;
}
13) Delete Image
Call function alert() on Delete Button in ShowPhoto.java
public void alert(){
AlertDialog.Builder alertDialogBuilder = new AlertDialog.Builder(this);
alertDialogBuilder.setTitle("Delete Photo");
alertDialogBuilder
.setMessage("are you sure you want to delete ?")
.setCancelable(false)

setResult(RESULT_OK, intent);
