如果我尝试像这样添加我的 FileProvider：
<provider
android:name="android.support.v4.content.FileProvider"
android:authorities="${applicationId}.myfileprovider"
android:exported="false"
android:grantUriPermissions="true">
<meta-data
android:name="android.support.FILE_PROVIDER_PATHS"
android:resource="@xml/provider_paths" />
</provider>
我遇到了以下问题：
Caused by: java.lang.RuntimeException: Manifest merger failed with multiple errors, see logs

如果我删除“当局”行，我会得到：
Manifest merger failed : Attribute meta-data#android.support.FILE_PROVIDER_PATHS@resource value=(@xml/provider_paths) from AndroidManifest.xml:374:17-55
is also present at [io.smooch:ui:5.12.5] AndroidManifest.xml:50:17-51 value=(@xml/file_paths).
Suggestion: add 'tools:replace="android:resource"' to <meta-data> element at AndroidManifest.xml:372:13-374:58 to override.
我也添加了'tools:replace="android:resource"'，但它又回到了旧的错误。我该怎么做才能正确合并它们？
编辑：
这是我的 providers_path.xml 文件：
<?xml version="1.0" encoding="utf-8"?>
<paths xmlns:android="http://schemas.android.com/apk/res/android">
<external-path
name="external_files"
path="." />
</paths>
这是我需要采取的文件： Environment.getExternalStorageDirectory() + "/Passenger/passenger_log.txt";
我需要在我的提供程序路径中添加什么？试图理解外部路径的逻辑。
此刻我明白了：

此代码导致崩溃，在 FileProvider 行：
File file = new File(Environment.getExternalStorageDirectory() + "/Passenger/log.zip");
Intent emailIntent = new Intent(android.content.Intent.ACTION_SEND);
emailIntent.setType("plain/text");
emailIntent.putExtra(android.content.Intent.EXTRA_EMAIL, new String[]{"support@psngr.co"});
emailIntent.putExtra(android.content.Intent.EXTRA_SUBJECT, "Psngr Android Logs");
emailIntent.putExtra(android.content.Intent.EXTRA_TEXT, "Thanks for helping us improve Psngr!\n Please describe the issue you found");
emailIntent.putExtra(Intent.EXTRA_STREAM, FileProvider.getUriForFile(getActivity(), Constants.PROVIDER_AUTHORITY, file));
startActivity(Intent.createChooser(emailIntent, "Send Feedback..."));
PSApplicationClass.getInstance().showSavingPopup = getString(R.string.email_sent);
