Question

我已经设法获取屏幕截图并创建位图文件。现在我想把它发送到一个特定的gmail（我的）。跑步时我没有收到任何错误，但也没有电子邮件。我究竟做错了什么？我确信它有些愚蠢，但无法弄明白。这是我的主要活动。

   package com.example.publi.myapplication1;

import android.content.Intent;
import android.graphics.Bitmap;
import android.net.Uri;
import android.os.Bundle;
import android.os.Environment;
import android.support.v7.app.AppCompatActivity;
import android.view.View;
import android.widget.Button;
import android.widget.ImageView;
import android.widget.TextView;

import java.io.ByteArrayOutputStream;
import java.io.File;
import java.io.FileOutputStream;

public class MainActivity extends AppCompatActivity {

    TextView textView;
    ImageView imageView;
    Bitmap mbitmap;
    Button captureScreenShot;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);


        textView = (TextView) findViewById(R.id.textView);
        textView.setText("Thank you for Ordering ALMA");

        captureScreenShot = (Button) findViewById(R.id.capture_screen_shot);
        imageView = (ImageView) findViewById(R.id.imageView);

    }

    public void screenShot(View view) {
        mbitmap = getBitmapOFRootView(captureScreenShot);
        imageView.setImageBitmap(mbitmap);
        createImage(mbitmap);
    }

    public Bitmap getBitmapOFRootView(View v) {
        View rootview = v.getRootView();
        rootview.setDrawingCacheEnabled(true);
        Bitmap bitmap1 = rootview.getDrawingCache();
        return bitmap1;
    }

    public void createImage(Bitmap bmp) {
        ByteArrayOutputStream bytes = new ByteArrayOutputStream();
        bmp.compress(Bitmap.CompressFormat.JPEG, 40, bytes);
        File file = new File(Environment.getExternalStorageDirectory() +
                "/capturedscreenandroid.jpg");
        try {
            file.createNewFile();
            FileOutputStream outputStream = new FileOutputStream(file);
            outputStream.write(bytes.toByteArray());
            outputStream.close();
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
    public void sendMail(String path) {
        Intent emailIntent = new Intent(android.content.Intent.ACTION_SEND);
        emailIntent.putExtra(android.content.Intent.EXTRA_EMAIL,
                new String[]{"my@gmail.com"});
        emailIntent.putExtra(android.content.Intent.EXTRA_SUBJECT,
                "Alma Test Mail");
        emailIntent.putExtra(android.content.Intent.EXTRA_TEXT,
                "This is an autogenerated mail from Alma's InAppMail app");
        emailIntent.setType("image/png");
        Uri myUri = Uri.parse("file://" + path);
        emailIntent.putExtra(Intent.EXTRA_STREAM, myUri);
        startActivity(Intent.createChooser(emailIntent, "Send mail..."));
    }
}

我还添加了mail.jar，activation.jar，aditional.jar 与下面的清单一起

    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
