android 通过电子邮件附件发送 public 存储文件
android send public storage file via email attachment
这是我之前 post1.
的后续
总而言之,我希望 MyApp 使用 Intent 将其数据文件发送到指定的电子邮件地址。我现在有以下代码:
public void onClickSend(View v) {
Intent i = new Intent(android.content.Intent.ACTION_SEND);
String Email[] = { "my.address@gmail.com" };
i.putExtra(android.content.Intent.EXTRA_EMAIL, Email);
i.putExtra(android.content.Intent.EXTRA_SUBJECT, "Report");
i.setType("text/plain");
File path = Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DOCUMENTS);
File f = new File(path, _tdSource.GetFileName());
Uri sUri = FileProvider.getUriForFile(v.getContext(), "org.myorg.myapp.fileprovider", f);
i.setData(sUri);
i.setFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
i.putExtra(Intent.EXTRA_STREAM, sUri);
startActivity(i);
}
MyApp 的清单文件包含以下内容:
<application
android:icon="@mipmap/ic_launcher"
android:label="@string/app_name"
android:roundIcon="@mipmap/ic_launcher_round"
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>
<activity android:name=".SubActivity"></activity>
<provider
android:name="android.support.v4.content.FileProvider"
android:authorities="org.myorg.myapp.fileprovider"
android:grantUriPermissions="true"
android:exported="false">
<meta-data
android:name="android.support.FILE_PROVIDER_PATHS"
android:resource="@xml/filepaths" />
</provider>
</application>
MyApp 在调用 FileProvider.getUriForFile() 时遇到异常。奇怪的是,异常是 java.lang.reflect.InvocationTargetException 并在 AppCompatViewInflater.onClick().
中被捕获
我不知道我做错了什么或该去哪里...
Intent intent = new Intent(Intent.ACTION_SEND);
intent.putExtra(Intent.EXTRA_EMAIL, address);
intent.putExtra(Intent.EXTRA_SUBJECT, subject);
intent.putExtra(Intent.EXTRA_STREAM, Uri.fromFile(file)); // attachment
intent.setType("message/rfc822"); // message content type
startActivity(Intent.createChooser(intent, "Share via");
