我已经在stackoverflow和Github上的所有链接中进行了搜索,找到了可能的答案,但是仍然遇到相同的错误。

以下是清单文件:

<application
    android:allowBackup="true"
    android:icon="@mipmap/ic_launcher"
    android:label="@string/app_name"
    android:roundIcon="@mipmap/ic_launcher_round"
    android:supportsRtl="true"
    android:theme="@style/AppTheme">
    <activity android:name=".MainActivity">
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>

    <provider android:authorities="com.example.aditya.pdf_report"
        android:exported="false" android:grantUriPermissions="true"
        android:name="android.support.v4.content.FileProvider"
        android:readPermission="com.company.aditya.pdf_report.READ">
        <meta-data android:name="android.support.FILE_PROVIDER_PATHS"
            android:resource="@xml/file_paths"/>
    </provider>
</application>

这是Java文件:

    File filelocation = new File(Environment.getExternalStorageDirectory().getAbsolutePath() + "/pdf_report/" + reportname.getText().toString().trim() + ".pdf" );
        Uri path;
        path = FileProvider.getUriForFile(MainActivity.this, getPackageName(),filelocation);
        Intent emailIntent = new Intent(Intent.ACTION_SEND);
// set the type to 'email'
        emailIntent .setType("vnd.android.cursor.dir/email");

        emailIntent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
        emailIntent .putExtra(Intent.EXTRA_STREAM, path);
// the mail subject
        emailIntent .putExtra(Intent.EXTRA_SUBJECT, "Here is the Branch Visit Report - Human Resources");
        startActivity(Intent.createChooser(emailIntent , "Send email..."));

这是file-paths.xml:

<paths xmlns:android="http://schemas.android.com/apk/res/android">
<files-path name="pdf_report" path="pdf_report/"/>
</paths>

这是我的包裹名称:

com.example.aditya.pdf_report

这是我的手机上保存Pdf的位置:

Environment.getExternalStorageDirectory().getAbsolutePath() + "/pdf_report"

我已经浏览了所有链接,但我认为它是我写错东西的文件paths.xml

答案 0 :(得分:0)

如下更改您的<?xml version="1.0" encoding="utf-8"?> <paths> <external-path name="external_files" path="." /> </paths> 。可能有用。

    cont=(EditText)findViewById(R.id.editcontact);


    final String MobilePattern = "[0-9]{10}";
    btn_log=(Button)findViewById(R.id.button_log);
    btn_log.setOnClickListener(new View.OnClickListener() {
       @Override
       public void onClick(View v) {

           final String phn=cont.getText().toString();


           if (!phn.matches(MobilePattern)) {
               Toast.makeText(LoginActivity.this, "Invalid Contact number", Toast.LENGTH_SHORT).show();
           } else {

               Intent i = new Intent(LoginActivity.this, RegisterActivity.class);
               startActivity(i);

           }
       }

   });
