启动 ChooserActivity 以与其他应用共享图像后应用关闭
App closed after starting ChooserActivity to share image with other apps
在带有 Android10 的三星设备上，我们遇到了问题，我们的应用程序在启动 ChooserActivity 以共享我们的应用程序创建的图像后关闭。
日志或其他任何内容都没有异常。对于用户来说，我们的应用程序似乎刚刚关闭。
我们在其他设备上没有看到这种行为。
但是在我的 Android 10 诺基亚测试设备上 logcat.
中有一个条目

随后出现警告
2020-05-06 15:48:04.034 2753-5090/? W/ChooserActivity: Could not load (content://packagename.provider/cache/image-to-share.jpeg) thumbnail/name for preview. If desired, consider using Intent#createChooser to launch the ChooserActivity, and set your Intent's clipData and flags in accordance with that method's documentation
我不知道这是否是三星设备不适合我们应用程序的原因。在我们的测试设备上，即使日志中出现此消息，也一切正常。
这是我们如何启动 ChooserActivity 的代码
val share = Intent(Intent.ACTION_SEND)
share.addFlags(Intent.FLAG_GRANT_WRITE_URI_PERMISSION)
share.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION)
share.type = "*/*"
share.putExtra(Intent.EXTRA_TEXT, link)
share.putExtra(Intent.EXTRA_STREAM, FileProvider.getUriForFile(activity!!, BuildConfig.APPLICATION_ID + ".provider", fileToShare!!))
startActivityForResult(Intent.createChooser(share, "Share Image"), REQUEST_CODE_CHOOSER_INTENT)
这里是我们文件提供者在AndroidManifest.xml
中的定义
<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/file_paths" />
</provider>
file_paths.xml 看起来像这样
<?xml version="1.0" encoding="utf-8"?>
<paths xmlns:android="http://schemas.android.com/apk/res/android">
<cache-path name="cache" path="."/>
</paths>
是否有人在三星设备上也遇到了这个问题，或者可以告诉我如何解决我们在日志中看到的错误，以便我们测试是否可以解决三星设备上的问题？
更新：
我们在日志中发现了以下异常。

有没有人知道这里发生了什么。 uri 权限集基本上就是我们的应用程序包名称。
如错误中所述，使文件提供程序可导出，在 AndroidManifest.xml 文件的提供程序组件中 -
android:exported="true"
试试吧。所以你的提供者看起来像 -
<provider
android:name="androidx.core.content.FileProvider"
android:authorities="${applicationId}.provider"
android:exported="true"
android:grantUriPermissions="true">
<meta-data
android:name="android.support.FILE_PROVIDER_PATHS"
android:resource="@xml/file_paths" />
</provider>
我设法通过一些变通办法解决了这个问题。当我试图将额外的 URL 传递给 ChooserActivity 时发生错误，例如
share.putExtra(Intent.EXTRA_TEXT, "https://my.domain.com")
这会导致 java.net.URISyntaxException 仅在带有 Android 10 的三星设备上出现，我在上面的问题中提到过。
像这样传递 URL 是可行的。
share.putExtra(Intent.EXTRA_TEXT, "https://www.my.domain.com")
但是我需要一个没有 www 的 URL，所以我在 URL 前后放了一个 space。这也有效。可能是因为 Samsung ChooserActivity 没有尝试将此字符串解析为 URL.
share.putExtra(Intent.EXTRA_TEXT, " https://my.domain.com ")
这个技巧对我有用。也许有人觉得它也有用，或者对我有解释，为什么会这样。
