在android 11中使用intent.resolveActivity时调用此方法时，请考虑向清单中添加查询声明 [英] Consider adding a queries declaration to your manifest when calling this method when using intent.resolveActivity in android 11

问题描述

我有一个扩展功能，可以为我的活动打开意图:

I've an extension function for opening an intent for my activities:

fun Activity.openIntent(action: String?, type: String?, uri: Uri?) {
    Intent()
        .apply {
            action?.let { this.action = it }
            uri?.let { this.data = it }
            type?.let { this.type = it }
        }
        .also { intent ->
            packageManager?.let {
                if (intent.resolveActivity(it) != null)
                    startActivity(intent)
                else
                    showToast(R.string.application_not_found)
            }
        }
}

我的 targetSdkVersion 是 30 .它在 intent.resolveActivity(it)中给我一个警告:

My targetSdkVersion is 30. It gives me a warning in intent.resolveActivity(it):

考虑在调用此方法时向清单中添加查询声明.

Consider adding a queries declaration to your manifest when calling this method.

那我该怎么办才能解决此警告?

So What should I do to solve this warning?

推荐答案

最简单的解决方案是摆脱 resolveActivity().替换:

The simplest solution is to get rid of resolveActivity(). Replace:

            packageManager?.let {
                if (intent.resolveActivity(it) != null)
                    startActivity(intent)
                else
                    showToast(R.string.application_not_found)
            }

具有:

            try {
                startActivity(intent)
            } catch (ex: ActivityNotFoundException) {
                showToast(R.string.application_not_found)
            }

这将为您提供相同的结果，但性能会有所提高，并且可以消除警告.

This gives you the same result with a bit better performance, and it will get rid of the warning.

另一种选择是添加 QUERY_ALL_PACKAGES 权限.这可能会让您被Play商店禁止.

Another option would be to add the QUERY_ALL_PACKAGES permission. This may get you banned from the Play Store.

否则，您将需要:

• 为您的应用可能进行的每个 openIntent()调用构建列表

添加< queries>清单中的元素，其中列出了您希望能够与 resolveActivity()

定期重复此过程，以防为 openIntent()

Repeat this process periodically, in case you add new scenarios for openIntent()
