首先请确保您已添加权限
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
然后使用此代码
Intent share = new Intent(Intent.ACTION_SEND);
share.setType("image/jpeg");
Uri imageUri = Uri.parse(this.imgUrl);
share.putExtra(Intent.EXTRA_STREAM, imageUri);
startActivity(Intent.createChooser(share, "Select"));

如果targetSdkVersion高于24，则使用Provider授予访问权限。
创建一个xml文件：res \ xml \ provider_paths.xml

现在在AndroidManifest.xml文件中添加提供程序
<?xml version="1.0" encoding="utf-8"?>
<paths xmlns:android="http://schemas.android.com/apk/res/android">
<external-path name="external_files" path="."/>
</paths>
并将其替换为您的代码
<provider
android:name="android.support.v4.content.FileProvider"
android:authorities="${applicationId}.provider"
android:exported="false"
android:grantUriPermissions="true">
<meta-data

更新
Intent share = new Intent("android.intent.action.SEND");
share.setType("image/jpeg");
Uri uri = FileProvider.getUriForFile(MainActivity.this, BuildConfig.APPLICATION_ID+ ".provider",new File(this.imgUrl));
share.putExtra("android.intent.extra.STREAM", uri);

尝试一下：
Intent shareIntent = new Intent();
shareIntent.setAction(Intent.ACTION_SEND);
shareIntent.putExtra(Intent.EXTRA_STREAM, uriToImage);
shareIntent.setType("image/jpeg");
startActivity(Intent.createChooser(shareIntent,getResources().getText(R.string.send_to)));
