附加到电子邮件的9个补丁png原始资源不是原始文件

我整个上午一直在与一个问题作斗争,并且以为我现在会问这里。

我使用以下代码将9个补丁图像附加到电子邮件中:

sendIntent.setType("image/png");

ArrayList<Uri> uris = new ArrayList<Uri>();

uris.add(Uri.parse("android.resource://com.android9patch.viewer/raw/" + mBaseFilename + String.format("%05d", mAppBackgroundCurrentFile)) );

sendIntent.putParcelableArrayListExtra(Intent.EXTRA_STREAM, uris);
startActivity(Intent.createChooser(sendIntent, "Email:"));

问题在于,当我收到电子邮件时,图像不是原始的9补丁,而是没有缩放和填充标记的版本。

我应该得到这个结果:   Expected result attachment

但我得到了这个: Result received

我怀疑应用程序在发送之前处理原始文件?

其他信息

我现在正尝试将文件保存到SDCARD,然后再将其附加到电子邮件中。好吧,出于某种原因,即使复制也会删除缩放和填充标记...我不明白。

这是我从raw copy function获取的复制功能。

private boolean copyToSDCard( int resourceID, String finalName )
{
    String extStorageDirectory = Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DOWNLOADS).toString();
    OutputStream out = null;

    try
    {
        InputStream in = getResources().openRawResource( resourceID );
        out = new FileOutputStream(extStorageDirectory + "/" + finalName + ".9.png");
        copyFile(in, out);
        in.close();
        in = null;
        out.flush();
        out.close();
        out = null;
    }
    catch (Exception e)
    {
        Log.e("copyToSDCard", e.toString());
        e.printStackTrace();
    }

    return false;
}

private void copyFile(InputStream in, OutputStream out) throws IOException {
    byte[] buffer = new byte[1024];
    int read;
    while((read = in.read(buffer)) != -1){
      out.write(buffer, 0, read);
    }
}

答案 0 :(得分:0)

我最终将资产复制到SD卡并使用以下功能将此新文件附加到电子邮件中:

...
if( copyAssetToSDCard( filename, basepath + filename ) )
{
    uris.add( Uri.parse( "file://" + basepath + filename ) );
}
...


private boolean copyAssetToSDCard( String SrcFilename, String DstFilename )
{
    OutputStream out = null;

    try
    {
        AssetManager assetManager = getResources().getAssets();
        InputStream in = assetManager.open(SrcFilename);
        out = new FileOutputStream(DstFilename);
        copyFile(in, out);
        in.close();
        in = null;
        out.flush();
        out.close();
        out = null;

        return true;
    }
    catch (Exception e)
    {
        Log.e("copyToSDCard", e.toString());
        e.printStackTrace();
    }

    return false;
}

private void copyFile(InputStream in, OutputStream out) throws IOException {
    byte[] buffer = new byte[1024];
    int read;
    while((read = in.read(buffer)) != -1){
      out.write(buffer, 0, read);
    }
}
