无法附加文件发送电子邮件的android 11 [英] couldn't attach file send email android 11
问题描述
我正在开发一个通过电子邮件发送处理报告的应用程序.在应用程序中完成处理数据后，用户将发送一封包含处理数据的电子邮件.但是，我在Android 11上遇到问题.将报告附加到电子邮件时，无论使用哪种电子邮件应用程序，都会出现一条消息:无法附加文件.我一直在研究，发现它可能与在android 11版本的设备上访问设备内部存储的权限有关.我希望我能帮助您发送带有android 11附件文件的电子邮件./p>
我的代码:清单

val报告= File(mFilePathDaily)val uri = FileProvider.getUriForFile(activity.requireContext()，activity.requireContext().applicationContext.packageName +.provider"，报告)val i = Intent(Intent.ACTION_SENDTO)i.data = Uri.parse("mailto:")i.putExtra(Intent.EXTRA_EMAIL，arrayOf("testesdissertacao@gmail.com"))i.putExtra(Intent.EXTRA_SUBJECT，EMAIL_SUBJECT)i.putExtra(Intent.EXTRA_TEXT，基准测试")i.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK)i.putExtra(Intent.EXTRA_STREAM，uri)//i.type ="image/png"activity.requireContext().startActivity(Intent.createChooser(i，null))progressDialog.dismiss() 现在的问题是，您找不到要附加到电子邮件的报告.我注意到该报告保存在模拟器的另一个文件夹中，而不是根文件夹中.我认为这就是为什么您找不到要附加到电子邮件的文件的原因.
请勿将文件附加到电子邮件中
我已成功将图像附加到电子邮件中，我会给您一个代码
将您的URI转换为文件
private void共享(文件保存路径){如果(savePath！= null){Uri uri = FileProvider.getUriForFile(context，context.getApplicationContext().getPackageName()+".provider"，savePath);意图i =新意图(Intent.ACTION_SEND);i.putExtra(Intent.EXTRA_EMAIL，新的String [] {"fake@fake.edu"})；i.putExtra(Intent.EXTRA_SUBJECT，在工作中")；//Log.d("URI @！@#！#！@ ## !!，Uri.fromFile(pic).toString()+"" pic.exists());i.putExtra(Intent.EXTRA_TEXT，电子邮件的所有详细信息都在消息中")；i.putExtra(Intent.EXTRA_STREAM，uri);i.setType("image/png")；context.startActivity(Intent.createChooser(i，在工作中分享你")))；} 如何在XML路径中添加提供程序首先，您必须创建一个XML资源文件夹，然后创建一个XML资源文件.粘贴此代码后
<路径xmlns:android ="http://schemas.android.com/apk/res/android">< external-path name ="external_files"path ="."</paths> 然后还添加了清单
<提供者android:name =" androidx.core.content.FileProvider"android:authorities =" $ {applicationId} .provider"android:exported =" false"android:grantUriPermissions =" true"><元数据android:name ="android.support.FILE_PROVIDER_PATHS"android:resource =" @ xml/provider_paths"/></provider>
I am developing an application that sends processing reports via email. When completing the processing data in the application, the user sends an email containing the processing data. However, I am facing a problem on Android 11. When attaching the report to the email, regardless of the email application, a message appears: the file could not be attached. I've been researching a little and saw that it may be related to the permission to access the internal storage of the device on devices with version of android 11. I would like me to help you send email with file attached on android 11.
My code: Manifest
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<application
android:allowBackup="true"
android:icon="@mipmap/ic_launcher"
android:label="@string/app_name"
android:networkSecurityConfig="@xml/network_security_config"
android:roundIcon="@mipmap/ic_launcher_round"
android:supportsRtl="true"
android:theme="@style/AppTheme"
android:requestLegacyExternalStorage="true"
tools:ignore="AllowBackup"
tools:targetApi="n">
<activity.....
<provider
android:name="androidx.core.content.FileProvider"
android:authorities="${applicationId}.provider"
android:exported="false"
android:grantUriPermissions="true">
<meta-data
android:name="android.support.FILE_PROVIDER_PATHS"
android:resource="@xml/file_paths" />
</provider>
</application>
My xml:
<?xml version="1.0" encoding="utf-8"?>
<paths>
<external-path name="external_files" path="."/>
</paths>
Save file .pdf
val mDocProc = Document()
val file =
File(
Environment.getExternalStorageDirectory()
.toString() + "/" + "Relatório diário" + date + ".pdf"
)
if (file.exists()) {
file.delete()
}
//pdf file path
mFilePathDaily =
Environment.getExternalStorageDirectory()
.toString() + "/" + "Relatório diário " + date + ".pdf"
Class send email:
val report = File(mFilePathDaily)
val uri = FileProvider.getUriForFile(
activity.requireContext(),
activity.requireContext().applicationContext.packageName + ".provider",
report
)
val i = Intent(Intent.ACTION_SENDTO)
i.data = Uri.parse("mailto:")
i.putExtra(Intent.EXTRA_EMAIL, arrayOf("testesdissertacao@gmail.com"))
i.putExtra(Intent.EXTRA_SUBJECT, EMAIL_SUBJECT)
i.putExtra(Intent.EXTRA_TEXT, "Segue em anexo o relatório de Benchmark")
i.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK)
i.putExtra(Intent.EXTRA_STREAM, uri)
//i.type = "image/png"
activity.requireContext().startActivity(Intent.createChooser(i, null))
progressDialog.dismiss()
Now the problem is that you can't find the report to attach to the email. I noticed that the report was saved inside that other folder in the emulator, and not in the root folder. I think that is why you are not finding the file to attach to the email.
Do not attach the file to the email
I have attached the image successfully in email i will give you a code
convert your URI to file
private void Share(File savepath) {
if (savePath != null) {
Uri uri = FileProvider.getUriForFile(context, context.getApplicationContext().getPackageName() + ".provider", savePath);
Intent i = new Intent(Intent.ACTION_SEND);
i.putExtra(Intent.EXTRA_EMAIL, new String[]{"fake@fake.edu"});
i.putExtra(Intent.EXTRA_SUBJECT,"On The Job");
//Log.d("URI@!@#!#!@##!", Uri.fromFile(pic).toString() + " " + pic.exists());
i.putExtra(Intent.EXTRA_TEXT,"All Detail of Email are here in message");
i.putExtra(Intent.EXTRA_STREAM,uri);
i.setType("image/png");
context.startActivity(Intent.createChooser(i,"Share you on the jobing"));
}
how to add provider in XML path first, you have to create an XML resource folder then create an XML resource file after pasting this code
<paths xmlns:android="http://schemas.android.com/apk/res/android">
<external-path name="external_files" path="."/>
</paths>
then also add-in manifest
<provider
android:name="androidx.core.content.FileProvider"
android:authorities="${applicationId}.provider"
android:exported="false"
android:grantUriPermissions="true">
<meta-data
android:name="android.support.FILE_PROVIDER_PATHS"
android:resource="@xml/provider_paths" />
</provider>
