Android:在 htc Hero 上选择 Gmail 应用程序时，带有 EXTRA_STREAM 的 Intent.ACTION_SEND 不会附加任何图像 [英] Android: Intent.ACTION_SEND with EXTRA_STREAM doesn't attach any image when choosing Gmail app on htc Hero

问题描述

在带有默认邮件应用程序的模拟器上一切正常.但是当我收到一封使用 Gmail 应用程序从我的英雄发送的邮件时，我没有附件.英雄上的默认邮件应用程序运行良好.

On the Emulator with a default mail-app all works fine. But I have no attach when I'am receiving a mail which I've sent from my Hero using a Gmail app. The default Mail app on the hero works fine.

如何使此代码适用于 Hero 上的 Gmail 应用程序?
你可以看到下面的代码.

How can I make this code works with Gmail app on Hero?
You can see the code below.

    private void startSendIntent() {
        Bitmap bitmap = Bitmap.createBitmap(editableImageView.getWidth(), editableImageView.getHeight(), Bitmap.Config.RGB_565);
        editableImageView.draw(new Canvas(bitmap));
        File png = getFileStreamPath(getString(R.string.file_name));
        FileOutputStream out = null;
        try {
            out = openFileOutput(getString(R.string.file_name), MODE_WORLD_READABLE);
            bitmap.compress(Bitmap.CompressFormat.PNG, 100, out);
            out.flush();
        } catch (Exception e) {
            e.printStackTrace();
        } finally {
            try {
                if (out != null) out.close();
            }
            catch (IOException ignore) {}
        }
        final Intent emailIntent = new Intent(android.content.Intent.ACTION_SEND);
        emailIntent.putExtra(Intent.EXTRA_STREAM, Uri.fromFile(png));
        emailIntent.setType("image/png");
        startActivity(Intent.createChooser(emailIntent, getString(R.string.send_intent_name)));
}

在日志中，我看到以下内容:

in Logs I see the following:

谢谢你的回答.

推荐答案

对我来说，问题是通过以下几行代码解决的:

For me the problem was solved with the following lines of code:

Bitmap screenshot = Bitmap.createBitmap(_rootView.getWidth(), _rootView.getHeight(), Bitmap.Config.RGB_565);
_rootView.draw(new Canvas(screenshot));

String path = Images.Media.insertImage(getContentResolver(), screenshot, "title", null);
Uri screenshotUri = Uri.parse(path);

final Intent emailIntent = new Intent(android.content.Intent.ACTION_SEND);
emailIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
emailIntent.putExtra(Intent.EXTRA_STREAM, screenshotUri);
emailIntent.setType("image/png");

startActivity(Intent.createChooser(emailIntent, "Send email using"));

关键是我将屏幕截图保存到媒体库，然后它可以从那里成功发送文件.

The key thing is that I'm saving the screen-shot to the media library and then it can successfully send a file from there.
