使用 GMail 应用附加 apk 文件时权限被拒绝 android
Permisssion denied while attaching apk file with GMail app android
我有一个通过share Intent发送apk文件的需求，我也顺利实现了。但问题仅在通过 GMail 发送 apk 时出现，我在尝试附加时收到 permission denied。我真的不知道 GMail 发生了什么。请帮助我完成您的答案和解决方案。任何小提示和技巧对我也很有用。提前致谢
我正在使用以下代码通过共享意图发送 APK：
public static void appSend(ArrayList<File> files,Context context){
Intent shareIntent = new Intent(Intent.ACTION_SEND_MULTIPLE);
shareIntent.setType("application/vnd.android.package-archive");
shareIntent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_WHEN_TASK_RESET);
ArrayList<Uri> uriFiles = new ArrayList<Uri> ();
for(File file: files) {
uriFiles.add (Uri.fromFile (file));
}
shareIntent.putParcelableArrayListExtra (Intent.EXTRA_STREAM, uriFiles);
try {
context.startActivity (Intent.createChooser (shareIntent, "Share via"));
} catch (android.content.ActivityNotFoundException ex) {
Toast.makeText (context, "There are no share applications installed.", Toast.LENGTH_SHORT).show();

在应用程序之间共享文件时，您应该使用 FileProvider as per the setting up file sharing training，因为这样可以确保接收应用程序无需任何权限即可读取文件。从 Android 6.0 开始，Gmail 不请求存储权限，这意味着它无法读取您提供的任何文件 Uri.fromFile()。
您将在清单中声明 FileProvider：
<provider
android:name="android.support.v4.content.FileProvider"
android:authorities="com.example.myapp.fileprovider"
android:grantUriPermissions="true"
android:exported="false">
<meta-data
android:name="android.support.FILE_PROVIDER_PATHS"
android:resource="@xml/filepaths" />
</provider>
一个 XML 文件（在本例中称为 filepaths.xml 以匹配上面的清单声明），它通过 FileProvider:
确定哪些目录可用
<paths>
<files-path path="images/" name="myimages" />
</paths>
然后，代替使用 Uri.fromFile(file)，您使用 FileProvider.getUriForFile()，传递与清单中相同的权限。
