ContentResolver.takePersistableUriPermission：SecurityException 未找到 UID 10434 和 Uri 内容的持久权限授予：/

Question

我注意到以下异常（Firebase Crashlytics）：

Fatal Exception: java.lang.RuntimeException
Failure delivering result ResultInfo{who=null, request=1915322883, result=-1, data=Intent { dat=content:/... flg=0xc3 }} to activity {com..../com....Activity}: java.lang.SecurityException: No persistable permission grants found for UID 10571 and Uri content:/...

Fatal Exception: java.lang.SecurityException
No persistable permission grants found for UID 10434 and Uri content:/...

android.content.ContentResolver.takePersistableUriPermission (ContentResolver.java:2952)

Caused by android.os.RemoteException
Remote stack trace: at com.android.server.uri.UriGrantsManagerService.takePersistableUriPermission(UriGrantsManagerService.java:385) at android.app.IUriGrantsManager$Stub.onTransact(IUriGrantsManager.java:139) at android.os.Binder.execTransactInternal(Binder.java:1375) at android.os.Binder.execTransact(Binder.java:1311)

当应用程序调用

ContentResolver.takePersistableUriPermission

时：

val safResultLauncher = rememberLauncherForActivityResult(
    contract = ActivityResultContracts.StartActivityForResult()
) { activityResult ->
    coroutineScope.launch {
        if (activityResult.resultCode == Activity.RESULT_OK) {
            val treeUri = activityResult.data?.data
            if (treeUri != null) {
                context.contentResolver.takePersistableUriPermission(
                    treeUri,
                    Intent.FLAG_GRANT_READ_URI_PERMISSION or Intent.FLAG_GRANT_WRITE_URI_PERMISSION
                )
            }
        }
    }
}

// select a folder
try {
    safResultLauncher.launch(Intent.ACTION_OPEN_DOCUMENT_TREE)
} catch (e: Throwable) {
    // ...
}

Answer 1

当您请求许可时，无法保证您会获得持久的许可。您的应用程序可以请求的数量有限（过去的限制是 128，但对于您的设备来说应该是 512）。此外，制造商或

DocumentsProvider

开发人员可能不会为用户所做的某些选择提供持久权限。

您需要优雅地处理

takePersistableUriPermission()

抛出异常的情况。
