改变你的 provider.xml 文件,使其更加广泛,更加方便:

<?xml version="1.0" encoding="utf-8"?>
<paths>
    <external-path
        name="external_files"
        path="." />
</paths>

然后在 Java 中:

public static void shareVideo(Context context, String fullPath) {
    try {
        File file = new File(fullPath);
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) {
            Uri videoUri = FileProvider.getUriForFile(context, BuildConfig.APPLICATION_ID + ".provider", file);
            Intent intent = new Intent(Intent.ACTION_SEND);
            intent.putExtra(Intent.EXTRA_STREAM, videoUri);
            intent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
            intent.setData(videoUri);
            intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
            context.startActivity(Intent.createChooser(intent, "分享标题"));
        } else {
            Uri videoUri = Uri.fromFile(file);
            Intent intent = new Intent(Intent.ACTION_SEND);
            intent.putExtra(Intent.EXTRA_STREAM, videoUri);
            intent.setDataAndType(videoUri, "video/*");
            intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
            context.startActivity(Intent.createChooser(intent, "分享标题"));
        }
    } catch (Exception e) {
        e.printStackTrace();
    }
}

不要忘记将以下内容添加到你的 AndroidManifest.xml 文件中:

<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>
英文:

Change your provider.xml to a broader extend which is more convenient:

&lt;?xml version=&quot;1.0&quot; encoding=&quot;utf-8&quot;?&gt;
&lt;paths&gt;
    &lt;external-path
        name=&quot;external_files&quot;
        path=&quot;.&quot; /&gt;
&lt;/paths&gt;

And then in java:

    public static void shareVideo(Context context, String fullPath) {
    try {
        File file = new File(fullPath);
        if (Build.VERSION.SDK_INT &gt;= Build.VERSION_CODES.N) {
            Uri videoUri = FileProvider.getUriForFile(context, BuildConfig.APPLICATION_ID + &quot;.provider&quot;, file);
            Intent intent = new Intent(Intent.ACTION_SEND);
            intent.putExtra(Intent.EXTRA_STREAM, videoUri);
            intent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
            intent.setData(videoUri);
            intent.addFlags(FLAG_ACTIVITY_NEW_TASK);
            context.startActivity(Intent.createChooser(intent, &quot;share title&quot;));
        } else {
            Uri videoUri = Uri.fromFile(file);
            Intent intent = new Intent(Intent.ACTION_SEND);
            intent.putExtra(Intent.EXTRA_STREAM, videoUri);
            intent.setDataAndType(videoUri, &quot;video/*&quot;);
            intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
            context.startActivity(Intent.createChooser(intent, &quot;share title&quot;));
        }
    } catch (Exception e) {
        e.printStackTrace();
    }
}

Don't forget to add this to your AndroidManifest.xml file:

&lt;provider
        android:name=&quot;androidx.core.content.FileProvider&quot;
        android:authorities=&quot;${applicationId}.provider&quot;
        android:exported=&quot;false&quot;
        android:grantUriPermissions=&quot;true&quot;&gt;
        &lt;meta-data
            android:name=&quot;android.support.FILE_PROVIDER_PATHS&quot;
            android:resource=&quot;@xml/provider_paths&quot; /&gt;
 &lt;/provider&gt;
