我已经尝试解决这个问题将近 3 天了,但我根本无法成功。我查看了所有可能的主题,但没有任何效果。

这是功能代码:

Bitmap image = Bitmap.createBitmap(_view.getWidth(), _view.getHeight(), Bitmap.Config.ARGB_8888);
        Canvas canvas = new Canvas(image);
        android.graphics.drawable.Drawable bgDrawable = _view.getBackground();
        if (bgDrawable!=null) {
            bgDrawable.draw(canvas);
        } else {
            canvas.drawColor(Color.WHITE);
        }
        _view.draw(canvas);
        java.io.File pictureFile = new java.io.File(Environment.getExternalStorageDirectory() + "/Phrasee/imagem.jpg");
        if (pictureFile == null) {
            return;
        }
        try {
            java.io.FileOutputStream fos = new java.io.FileOutputStream(pictureFile); 
            image.compress(Bitmap.CompressFormat.JPEG, 100, fos);
            fos.close();
        } catch (java.io.FileNotFoundException e) {
            Toast.makeText(getApplicationContext(), e.toString(), Toast.LENGTH_LONG).show();
        } catch (java.io.IOException e) {
            Toast.makeText(getApplicationContext(), e.toString(), Toast.LENGTH_LONG).show();
        }
            File imagePath = new File(Environment.getExternalStorageDirectory(), "/Phrasee/");
            File newFile = new File(imagePath, "imagem.jpg");
            Uri contentUri = FileProvider.getUriForFile(getApplicationContext(), getApplicationContext().getPackageName() + ".provider", newFile); 
            File sdDir = new File(Environment.getExternalStorageDirectory() + "/Phrasee/imagem.jpg");
                Intent iten = new Intent(android.content.Intent.ACTION_SEND);
                 iten.setType("image/jpeg");
                 iten.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
                iten.putExtra(Intent.EXTRA_STREAM, FileProvider.getUriForFile(getApplicationContext(), getApplicationContext().getPackageName() + ".provider", new java.io.File(Environment.getExternalStorageDirectory(), "/Phrasee/")));
                 startActivity(Intent.createChooser(iten, "Share with:"));

这就是清单中的提供者的样子:

<provider

            android:authorities="gd.rf.tosproductions.phrasee.provider"
            android:name="androidx.core.content.FileProvider"
            android:exported="false"
            android:grantUriPermissions="true">
            <meta-data
                android:name="android.support.FILE_PROVIDER_PATHS"
                android:resource="@xml/provider_paths" />
        </provider>

我还导入了androidx.core.content.FileProvider

显示可以共享图像的应用程序的对话框出现。但每当我选择 WhatsApp 或任何其他应用程序时,就会出现写有“共享失败,请重试”的祝酒词。

最后,我也已经设置了 provider_paths.xml。

<?xml version="1.0" encoding="utf-8"?>
<paths>
    <external-path name="external_files" path="."/>
</paths>

我真的不知道该怎么办。请给我一个可以解决的解决方案..
