试试这个来保存文件：
{尝试
myfile文件=新的文件（/ SD卡/ mysdfile.jpg）;
myFile.createNewFile（）;
FileOutputStream中FOUT =新的FileOutputStream（MYFILE）;
OutputStreamWriter myOutWriter =
新OutputStreamWriter（FOUT）;
myOutWriter.append（txtData.getText（））;
myOutWriter.close（）;
fOut.close（）;
Toast.makeText（getBaseContext（），
写完SD'mysdfile.txt'
Toast.LENGTH_SHORT）.show（）;
}赶上（例外五）{
Toast.makeText（getBaseContext（），e.getMessage（），
Toast.LENGTH_SHORT）.show（）;
} 意图emailIntent =新意图（android.content.Intent.ACTION_SEND）;
emailIntent.setType（应用/图像）;
emailIntent.putExtra（android.content.Intent.EXTRA_EMAIL，新的String [] {strEmail}）;
emailIntent.putExtra（android.content.Intent.EXTRA_SUBJECT，测试对象）;
emailIntent.putExtra（android.content.Intent.EXTRA_TEXT，从我的应用程序）;
emailIntent.putExtra（Intent.EXTRA_STREAM，Uri.parse（文件：///mnt/sdcard/mysdfile.jpg））;
startActivity（Intent.createChooser（emailIntent，发送邮件...））;
和确保你在你的清单中添加正确的权限：
＆LT;使用许可权的android：NAME =android.permission.WRITE_EXTERNAL_STORAGE＆GT;
I'm trying to embed a inline image in email body by saving in sdcard and then picking from that place but image is not being shown and just "obj" is shown there.Kindly help me out,here is the code of my function:
{
Bitmap newImg=BitmapFactory.decodeByteArray(img,0,img.length);
String root = Environment.getExternalStorageDirectory().toString();
File myDir = new File(root + "/saved_images");
myDir.mkdirs();
String fname = "stoneage.jpg";
File file = new File (myDir, fname);
try{
FileOutputStream out = new FileOutputStream(file);
newImg.compress(Bitmap.CompressFormat.JPEG, 90, out);
out.flush();
out.close();
} catch (Exception e) {
e.printStackTrace();
}
Uri uri = null;
uri = Uri.parse("file://" + Environment.getExternalStorageDirectory()+"/saved_images/"+fname);
String txtBody = "<html><body><h1>hi it is stoneage product</h1><br><img src ="+uri+"/></body></html>";
Log.d("data", txtBody);
Intent emailIntent = new Intent(android.content.Intent.ACTION_SEND);
emailIntent.setType("text/html");
emailIntent.putExtra(android.content.Intent.EXTRA_SUBJECT, "testemail");
emailIntent.putExtra(android.content.Intent.EXTRA_TEXT, Html.fromHtml(txtBody));
startActivity(Intent.createChooser(emailIntent, "Email:")); }
解决方案
Try this to save the file:
try {
File myFile = new File("/sdcard/mysdfile.jpg");
myFile.createNewFile();
FileOutputStream fOut = new FileOutputStream(myFile);
OutputStreamWriter myOutWriter =
new OutputStreamWriter(fOut);
myOutWriter.append(txtData.getText());
myOutWriter.close();
fOut.close();
Toast.makeText(getBaseContext(),
"Done writing SD 'mysdfile.txt'",
Toast.LENGTH_SHORT).show();
} catch (Exception e) {
Toast.makeText(getBaseContext(), e.getMessage(),
Toast.LENGTH_SHORT).show();
}
Intent emailIntent = new Intent(android.content.Intent.ACTION_SEND);
emailIntent.setType("application/image");
emailIntent.putExtra(android.content.Intent.EXTRA_EMAIL, new String[]{strEmail});
emailIntent.putExtra(android.content.Intent.EXTRA_SUBJECT,"Test Subject");
emailIntent.putExtra(android.content.Intent.EXTRA_TEXT, "From My App");
emailIntent.putExtra(Intent.EXTRA_STREAM, Uri.parse("file:///mnt/sdcard/mysdfile.jpg"));
startActivity(Intent.createChooser(emailIntent, "Send mail..."));
And make sure you add the correct permission in your manifest:
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE">
