我看到了有关此的其他问题,尝试了他们的答案,但没有用。我正在尝试使用developer.android.com的第二种方法。(第二个白色子弹)。我使用适当的权限将图像保存到应用程序内部存储器。图像(位图)已成功保存,但我无法将其附加到新意图以共享它。这是我的代码:
Intent shareIntent = new Intent(Intent.ACTION_SEND);
shareIntent.setType("*/*");//Attach all types (images/text)
FileOutputStream fos;
try{
fos = openFileOutput(myfilename, Context.MODE_WORLD_READABLE);
mybitmap.compress(Bitmap.CompressFormat.PNG, 90, fos);
fos.flush();
//Image is stored successfully (checked data/data/mypackage/files/myfilename)
Uri uri = Uri.fromFile(getFileStreamPath(myfilename));
shareIntent.putExtra(Intent.EXTRA_STREAM, uri);
}
catch (Exception e){
// noth
//Log.e(TAG, e.getStackTrace().toString());
}
shareIntent.putExtra(Intent.EXTRA_TEXT, "some text also");
return shareIntent;
}
应用程序说不能附加媒体项目。Gmail 似乎附加了项目,但在发送邮件时它什么也没显示!
uri.getPath 也返回我:/data/data/mypackage/files/myfilename,这是正确的
有任何想法吗?谢谢!
编辑:修改代码以使用 sd 卡。仍然无法正常工作:
File imgDir;
if (android.os.Environment.getExternalStorageState().equals(
android.os.Environment.MEDIA_MOUNTED))
imgDir = new File(
android.os.Environment.getExternalStorageDirectory(),
".MyAppName/Images");
else imgDir = MyActivity.this.getCacheDir();
if (!imgDir.exists()) imgDir.mkdirs();
File output = new File(imgDir, myFilename);
OutputStream imageFileOS;
try{
Uri uriSavedImage = Uri.fromFile(output);
imageFileOS = getContentResolver().openOutputStream(
uriSavedImage);
bitmapBookCover.compress(Bitmap.CompressFormat.PNG, 90,
imageFileOS);
imageFileOS.flush();
imageFileOS.close();
//Again image successfully saved
shareIntent.putExtra(Intent.EXTRA_STREAM, uriSavedImage);
}
catch (Exception e){
// noth
}
