不支持文件格式 \- 在 WhatsApp 上发送照片时

Question

        //Share image to all
        share = (Button)findViewById(R.id.facebook_app_id);
        share.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {

                Uri imageUri = Uri.parse("android.resource://" + getPackageName() +"/drawable/"+imageRes);
                Intent intent = new Intent(Intent.ACTION_SEND);
                intent.setType("image/*");

                intent.putExtra(Intent.EXTRA_STREAM, imageUri);
                intent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
                startActivity(Intent.createChooser(intent , "Share"));

            }

        });

我正在尝试构建一个照片共享应用程序。 Facebook、Messenger、Skype 完美运行，但 Whatsapp 和 Viber 显示错误 ( The file format is not supported )

以下是如何执行此操作的示例：

 public void shareImageWhatsApp() {

    Bitmap adv = BitmapFactory.decodeResource(getResources(), R.drawable.adv);
    Intent share = new Intent(Intent.ACTION_SEND);
    share.setType("image/jpeg");
    ByteArrayOutputStream bytes = new ByteArrayOutputStream();
    adv.compress(Bitmap.CompressFormat.JPEG, 100, bytes);
    File f = new File(Environment.getExternalStorageDirectory()
            + File.separator + "temporary_file.jpg");
    try {
        f.createNewFile();
        new FileOutputStream(f).write(bytes.toByteArray());
    } catch (IOException e) {
        e.printStackTrace();
    }
    share.putExtra(Intent.EXTRA_STREAM,
            Uri.parse( Environment.getExternalStorageDirectory()+ File.separator+"temporary_file.jpg"));
    if(isPackageInstalled("com.whatsapp",this)){
          share.setPackage("com.whatsapp");
          startActivity(Intent.createChooser(share, "Share Image"));

    }else{

        Toast.makeText(getApplicationContext(), "Please Install Whatsapp", Toast.LENGTH_LONG).show();
    }

}

private boolean isPackageInstalled(String packagename, Context context) {
    PackageManager pm = context.getPackageManager();
    try {
        pm.getPackageInfo(packagename, PackageManager.GET_ACTIVITIES);
        return true;
    } catch (NameNotFoundException e) {
        return false;
    }
}
