intent.action_send不在Oreo上工作[重复]

Question

Intent shareIntent = new Intent();
            shareIntent.setAction(Intent.ACTION_SEND);
            shareIntent.setType("image/jpeg");
            Uri uriShare = Uri.fromFile(outFile);
            //outfile is the path of the image stored in the gallery
            shareIntent.putExtra(Intent.EXTRA_STREAM, uriShare);
            startActivity(Intent.createChooser(shareIntent, ""));

有人能帮我解决这个问题吗？

如果targetsdkversion高于24，则使用FileProvider授予访问权限。

创建xml文件（路径:res\xml)provider_paths.xml

<?xml version="1.0" encoding="utf-8"?>
<paths xmlns:android="http://schemas.android.com/apk/res/android">
<root-path name="external_files" path="/" />
</paths>

在下的AndroidManifest.xml中添加提供程序

 <provider
    android:name="android.support.v4.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>

Uri uri = Uri.fromFile(fileImagePath);

Uri uri = FileProvider.getUriForFile(MainActivity.this, BuildConfig.APPLICATION_ID + ".provider",fileImagePath);
