Android 添加我的文件提供程序时出现问题

如果我尝试像这样添加我的文件提供程序：

<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>

如果我删除“权威”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.

这是我需要的文件：

Environment.getExternalStorageDirectory（）+“/Passenger/Passenger\u log.txt”

我需要在我的提供者路径中添加什么？试图理解外部路径的逻辑

此刻我明白了：

 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).

此代码在FileProvider行导致崩溃：

  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);

在代码中
这条线

 android:authorities="${applicationId}.myfileprovider" 

应该被替换为

 android:authorities="${applicationId}.provider"

您的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="." />
<root-path
        name="external_files"
        path="/storage/"/>
    </paths>


它现在可以构建了，但我还有一个问题。我需要在提供程序文件中确切地放置什么路径？如果这是我的文件路径：
files[0]=Environment.getExternalStorageDirectory（）+“/Passenger/Passenger_log.txt”仍然是相同的问题。正在尝试调试。还添加了导致路径崩溃的代码。getExternalStorageDirectory（）.toString（）+“/Passenger/Passenger_log.txt。获取外部存储后添加tostring。。我把它修好了，并把你的答案标为正确答案。谢谢。这真的救了我的命！我被困在如何定义xml文件的路径上，官方文档不清楚。但是set path=“”总是很好用。@pskink多亏了学习始终回答，我才成功地克服了这个问题。现在我在获取文件方面遇到了问题
