Question

复制步骤：

禁用或卸载设备上的所有浏览器
安装MX Player
启动MX Player并接受任何弹出窗口
按如下所示从应用程序中打开一个链接（假定代码在“活动”中）：

val url = "https://mylink.com"
val intent = Intent(Intent.ACTION_VIEW, Uri.parse(url))
val resolveInfo = context.packageManager.resolveActivity(intent, 0)
if (resolveInfo != null) {
    startActivity(intent)
} else {
    // error handling because no browser is installed
}

我的应用程序崩溃：

java.lang.SecurityException: Permission Denial: starting Intent { act=android.intent.action.VIEW dat=https://mylink.com.... cmp=com.mxtech.videoplayer.ad/com.mxtech.videoplayer.ActivityWebBrowser } from ProcessRecord{64f9702 20760:com.myapp/u0a65} (pid=20760, uid=10065) not exported from uid 10139

       at com.myapp.MyActivity.someFunction

仅当所有浏览器均已卸载/禁用时，我才看到此问题。在这种情况下，MX Player似乎会自己安装为浏览器，但无法处理从我的应用程序打开的链接。

您可以检查“活动”以查看URL是否已解析并使用以下内容导出：

private fun openUrl(url: String?) {
    if (url == null) return
    val intent = Intent(Intent.ACTION_VIEW)
    intent.addCategory(Intent.CATEGORY_DEFAULT)
    intent.data = Uri.parse(url)
    intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK)
    activity?.let {
        val activityInfo = intent.resolveActivityInfo(it.packageManager, intent.flags)
        if (activityInfo != null && activityInfo.exported) {
            ActivityCompat.startActivity(it, intent, null)
        }
    }
}

安装MX Player后，SecurityException崩溃会在外部浏览器中打开链接
