错误:无法使用文件提供程序在GMAIL应用中添加空文件 [英] Error: Cannot attach empty file in GMAIL app using File provider
问题描述
我试图在gmail应用程序中附加 pdf
文件。我已阅读
我对这行文件夹名称感到困惑< files-path name =pdf_folderpath =documents //>
。该文件位于 \Phone\documents
中。然后为什么选择文件夹名称?
编辑1
试图用 setType(message / rfc822)
替换 setType(application / pdf)
但没有奏效。任何帮助?
如果没关系发送Zip然后尝试这种方式
String fileNameStor_zip = Environment.getExternalStorageDirectory()+/+ fileName +.zip;
String [] path = {your 1st pdf File Path,你的第二个PDF文件路径};
压缩compress = new Compress(path,fileNameStor_zip);
压缩。 zip();
URI = Uri.parse(file://+ fileNameStor_zip);
提供您的Gmail Intent
intent.putExtra(Intent.EXTRA_STREAM,URI);
I am trying to attach a pdf
file in gmail app. I have read this and this (applied solution) I am trying as;
public static void attachFile(Context ctx) {
String TAG = "Attach";
File documentsPath = new File(ctx.getFilesDir(), "documents");
Log.i(TAG,"documentsAbsolutePath Output");
Log.i(TAG, documentsPath.getAbsolutePath().toString());
File file = new File(documentsPath, "sample.pdf");
if ( file.exists() ) {
Toast.makeText(ctx, "Exits", Toast.LENGTH_LONG).show();
}else{
Toast.makeText(ctx, "Not Exist", Toast.LENGTH_LONG).show();
}
Log.i(TAG,"file Output");
Log.i(TAG, file.toString());
Log.i(TAG, String.valueOf(file.length()));
Uri uri = FileProvider.getUriForFile(ctx, "com.example.fyp_awais.attachfiletest2.fileprovider", file);
Log.i(TAG,"URI Output");
Log.i(TAG,uri.toString());
Intent intent = ShareCompat.IntentBuilder.from((Activity) ctx)
.setType("application/pdf")
.setStream(uri)
.setChooserTitle("Choose bar")
.createChooserIntent()
.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
ctx.startActivity(intent);
}
Outputs
documentsAbsolutePath Output
/data/data/com.example.fyp_awais.attachfiletest2/files/documents
file Output

A pdf file is saved in Galaxy Core Prime\Phone\documents
. (file size: 53.7KB)
But it gives
Cannot attach empty file.
I am confused with folder-name in this line <files-path name="pdf_folder" path="documents/"/>
. The file is in the \Phone\documents
. Then why folder name?
Edit 1
Tried to replace setType(application/pdf)
with setType("message/rfc822")
But did not work. Any help?
if it's ok To send Zip then try this way
String fileNameStor_zip = Environment.getExternalStorageDirectory() + "/" + fileName + ".zip";
String[] path = { your 1st pdf File Path, your 2nd pdf File Path};
Compress compress = new Compress(path, fileNameStor_zip);
compress.zip();
URI = Uri.parse("file://" + fileNameStor_zip);
Provide your Gmail Intent
intent.putExtra(Intent.EXTRA_STREAM, URI);
