如果我尝试这样添加文件提供程序:

<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>

我有以下问题:

Caused by: java.lang.RuntimeException: Manifest merger failed with multiple errors, see logs
    at com.android.builder.core.AndroidBuilder.mergeManifestsForApplication(AndroidBuilder.java:524)
    at com.android.build.gradle.tasks.MergeManifests.doFullTaskAction(MergeManifests.java:143)

如果我删除“权限”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.

我还补充说 'tools:replace="android:resource"' 但后来又回到了过去的错误。我能做什么来正确地合并它们呢?

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>

这是我需要的文件: Environment.getExternalStorageDirectory() + "/Passenger/passenger_log.txt";

我需要在提供者路径中添加什么?试图理解外部路径的逻辑。

现在我明白了:

此代码导致文件提供程序行崩溃:

  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);
