添加我的 FileProvider 的问题

Question

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
    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 "authorities" 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.

我还添加了 'tools:replace="android:resource"' 但它又回到了旧错误。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>

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

我需要在我的提供商路径中添加什么？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);

Answer 1

在你的代码中这条线

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

应替换为

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

你的 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>
