Intent.ACTION_SENDがOreoで機能しない

写真をキャプチャしてギャラリーに保存するカスタムカメラアプリケーションを開発しています。 Intent.ACTION_SENDを使用してそのイメージを共有すると、API 26、つまりOREO。のデバイスを除くすべてのデバイスで問題なく機能します

画像を共有するための私のコードは次のとおりです。

Intent shareIntent = new Intent();
            shareIntent.setAction(Intent.ACTION_SEND);
            shareIntent.setType("image/jpeg");
            Uri uriShare = Uri.fromFile(outFile);
            //outfile is the path of the image stored in the gallery
            shareIntent.putExtra(Intent.EXTRA_STREAM, uriShare);
            startActivity(Intent.createChooser(shareIntent, ""));

誰かがこの問題を解決するのを手伝ってくれる？

targetSdkVersionが24より大きい場合は、アクセスを許可するために FileProvider が使用されます。

Xmlファイルを作成します（パス：res\xml）provider_paths.xml

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

AndroidManifest.xml にProviderを追加します

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

およびreplace

Uri uri = Uri.fromFile(fileImagePath);

に

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

これで完了です。

File Providerを使用してIMAGE URIを取得し、フラグをインテントに追加...これらの手順を慎重に実行してください。Android.os.FileUriExposedException：file：///storage/emulated/0/test.txt exposed through app through Intent.getData（）この更新は、ヌガー..
