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
在具有默认邮件应用程序的模拟器上一切正常。但是,当我收到我的 Hero 使用 Gmail 应用程序发送的邮件时,我没有附件。英雄上的默认邮件应用程序运行良好。
如何使此代码与 Hero 上的 Gmail 应用程序配合使用?
您可以看到下面的代码。
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:

谢谢您的回答。
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.
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)));
}
in Logs I see the following:
02-05 17:03:37.526: DEBUG/Gmail(11511): URI FOUND:file:///sdcard/DCIM/100MEDIA/IMAG0001.jpg
02-05 17:03:37.535: DEBUG/Gmail(11511): ComposeActivity added to message:0 attachment:|IMAG0001.jpg|image/jpeg|0|image/jpeg|LOCAL_FILE|file:///sdcard/DCIM/100MEDIA/IMAG0001.jpg size:0
02-05 17:03:37.585: INFO/Gmail(11511): >>>>> Attachment uri: file:///sdcard/DCIM/100MEDIA/IMAG0001.jpg

对我来说,问题是通过以下代码行解决的:
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。
For me the problem was solved with the following lines of code:
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.
getFileStreamPath()
或openFileOutput()
将在其他应用程序(即 Gmail)无法访问的私有目录中创建文件。使用外部存储创建可公开访问的文件:当外部存储不可用时(例如将其安装为 USB 驱动器时),此操作将不起作用。请参阅存储 API 指南,了解有关检测外部是否存在的更多信息存储空间可用。
如果您的最低 API 级别为 8 或更高,则可以使用
Context.getExternalCacheDir()
或Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_PICTURES)
作为父目录。除非您最终使用
getExternalCacheDir()
,否则请确保使用唯一的文件名以防止用户的文件之一被意外覆盖。最后,您可以重写
onActivityResult()
以在共享操作完成后删除文件:getFileStreamPath()
oropenFileOutput()
will create files in a private directory that is inaccessible to other apps (i.e. Gmail). Use external storage to create publicly-accessible files:This will not work when the external storage is unavailable, like when it is mounted as a USB drive. See the Storage API Guide for more about detecting whether external storage is available.
If your minimum API level is 8 or above, you can use
Context.getExternalCacheDir()
orEnvironment.getExternalStoragePublicDirectory(Environment.DIRECTORY_PICTURES)
as the parent directory.Unless you end up using
getExternalCacheDir()
, make sure you use a unique filename to prevent one of the users' files from accidentally getting overwritten.Finally, you can override
onActivityResult()
to delete the file after the share operation completes:我也有同样的症状。就我而言,这是因为我最初使用
MODE_PRIVATE
权限保存附件。当我将其更改为MODE_WORLD_READABLE
后,Gmail 似乎就能够访问该文件并正确发送附件。虽然我在您的代码片段中看到您使用的是MODE_WORLD_READABLE
...很奇怪。http://developer.android.com/reference/android/content/Context .html#MODE_WORLD_READABLE
I had the same symptoms. In my case it was because I was initially saving the attachment with the permissions
MODE_PRIVATE
. As soon as I changed it toMODE_WORLD_READABLE
it seems Gmail was then able to access the file and send the attachment properly. Although I see in your code snippet you were usingMODE_WORLD_READABLE
... weird.http://developer.android.com/reference/android/content/Context.html#MODE_WORLD_READABLE
