Android 11及以下版本Google Meet通过Intent打开链接崩溃求助

问题描述 #

在Android 11、10及更低版本中，Google Meet应用的com.google.android.libraries.communications.conference.ui.intents.AssistantNewUrlHandlerActivity存在权限处理缺陷：该Activity声明了android.permission.CALL_PHONE权限，但未正确配置对外调用的权限规则。当第三方应用通过Intent.ACTION_VIEW打开Meet会议链接时，系统会解析到这个有问题的Activity，触发SecurityException（权限拒绝）导致崩溃。

复现代码 #

private fun openGoogleMeetUrl() {
    val url = "https://meet.google.com/new"

    val webpage: Uri = Uri.parse(url)
    val intent = Intent(Intent.ACTION_VIEW, webpage)
    val resolveActivity = intent.resolveActivity(packageManager)

    if (resolveActivity != null) {
        startActivity(intent)
    } else {
        Log.w("DEBUG_TAG", "Unable to find activity to launch.")
    }
}

临时解决方案 #

以下几种方案可绕过该问题，避免崩溃：

方案1：指定Google Meet包名打开 #

直接限定Intent仅在Google Meet应用内处理，避免系统解析到有问题的Activity：

private fun openGoogleMeetUrl() {
    val url = "https://meet.google.com/new"
    val webpage: Uri = Uri.parse(url)
    val intent = Intent(Intent.ACTION_VIEW, webpage)
    // 指定Meet包名，引导系统选择正确的处理Activity
    intent.setPackage("com.google.android.apps.meetings")
    
    try {
        startActivity(intent)
    } catch (e: SecurityException) {
        // 权限异常时 fallback 到浏览器打开
        intent.setPackage(null)
        startActivity(intent)
    } catch (e: ActivityNotFoundException) {
        Log.w("DEBUG_TAG", "Google Meet未安装，使用浏览器打开")
        intent.setPackage(null)
        startActivity(intent)
    }
}

方案2：捕获异常并降级处理 #

在启动Activity时捕获权限拒绝异常，出现崩溃时自动切换到浏览器打开链接：

private fun openGoogleMeetUrl() {
    val url = "https://meet.google.com/new"
    val webpage: Uri = Uri.parse(url)
    val intent = Intent(Intent.ACTION_VIEW, webpage)
    val resolveActivity = intent.resolveActivity(packageManager)

    if (resolveActivity != null) {
        try {
            startActivity(intent)
        } catch (e: SecurityException) {
            Log.w("DEBUG_TAG", "打开Meet失败，切换至浏览器")
            // 清除组件信息，让系统选择浏览器应用
            intent.component = null
            startActivity(intent)
        }
    } else {
        Log.w("DEBUG_TAG", "无法找到可打开链接的应用")
    }
}

方案3：提前检测并替换问题Activity #

检查系统解析到的Activity是否为有问题的AssistantNewUrlHandlerActivity，若是则手动替换为Meet的主Activity：

private fun openGoogleMeetUrl() {
    val url = "https://meet.google.com/new"
    val webpage: Uri = Uri.parse(url)
    val intent = Intent(Intent.ACTION_VIEW, webpage)
    val resolveInfo = packageManager.resolveActivity(intent, PackageManager.MATCH_DEFAULT_ONLY)
    
    if (resolveInfo != null) {
        val problematicActivity = "com.google.android.libraries.communications.conference.ui.intents.AssistantNewUrlHandlerActivity"
        if (resolveInfo.activityInfo.name == problematicActivity) {
            // 替换为Meet主Activity
            intent.component = ComponentName("com.google.android.apps.meetings", "com.google.android.apps.meetings.MainActivity")
        }
        try {
            startActivity(intent)
        } catch (e: Exception) {
            Log.w("DEBUG_TAG", "打开失败，使用浏览器", e)
            intent.component = null
            startActivity(intent)
        }
    } else {
        Log.w("DEBUG_TAG", "无法找到可打开链接的应用")
    }
}

说明 #

该问题根源是Google Meet应用的权限配置错误，需Google官方修复上述Activity的权限声明逻辑。上述方案均为临时绕过手段，待Google修复后可移除相关处理。
