如何在 Android 中檢查其他應用程序是否使用輔助功能（BIND_ACCESSIBILITY_SERVICE）權限

Question

如何檢查是否有任何應用程序使用可訪問權限（BIND_ACCESSIBILITY_SERVICE），或者請求相同的應用程序的名稱以及是否授予它們？

要檢測以下應用程序正在使用輔助功能權限：

1. https://play.google.com/store/apps/details?id=you.in.spark.access.dots&hl=en_IN&gl=US
2. https://play.google.com/store/apps/details?id=com.oddlyspaced.burnermedia.burnerguard&hl=en_IN&gl=US
3. https://play.google.com/store/apps/details?id=com.lastpass.lpandroid&hl=en_IN&gl=US

已經嘗試過以下代碼，該代碼不適用於上述應用程序，不顯示 Access Dot 應用程序和 BurnerGuard 應用程序的任何條目，同時顯示 Last pass 的條目但不影響權限更改：

List<PackageInfo> allpackages = getPackageManager().getInstalledPackages(PackageManager.GET_PERMISSIONS);
    for(int i =0;i<allpackages.size();i++){
        PackageInfo pi = allpackages.get(i);
        if (pi.requestedPermissions == null) {
            // No permissions are requested in the AndroidManifest
            continue;
        }
        String[] requestedPermissions = pi.requestedPermissions;
        int[] requestPermissionFlags;
        for(int j=0;j<requestedPermissions.length;j++){
            String reqParm = requestedPermissions[j];
            int status = pi.requestedPermissionsFlags[j] & PackageInfo.REQUESTED_PERMISSION_GRANTED;
            
            try {
                PermissionInfo permissionInfo = getPackageManager().getPermissionInfo(reqParm,0);
      
                if(permissionInfo.name.equals("android.permission.BIND_ACCESSIBILITY_SERVICE")) {
                    if(status!=0) {
                        Log.i("accessibility", "Package Name :: " + pi.packageName + "    permission name :: " + permissionInfo.name + " Permission Granted " );
                    } else {
                        Log.i("accessibility", "Package Name :: " + pi.packageName + "    permission name :: " + permissionInfo.name + " Permission Requested " );
                    }
                }
            } catch (PackageManager.NameNotFoundException e) {
                //Log.e("accessibility", "Unknown permission: ");
                continue;
            }
    }

謝謝

對於一般權限（在清單中使用<uses-permission>聲明的權限），這應該為您提供所需的信息：

// Iterate over all installed packages and include information about their permissions
packageManager.getInstalledPackages(PackageManager.GET_PERMISSIONS).forEach { pkg ->
    // Find out if the current package has declared BIND_ACCESSIBILITY_SERVICE in its manifest..
    val index = pkg.requestedPermissions?.indexOf(Manifest.permission.BIND_ACCESSIBILITY_SERVICE) ?: -1
    if (index != -1) {
        // ..it has, so log whether the permission has been granted.
        val flags = pkg.requestedPermissionFlags[index]
        val grantStatus = if ((flags and PackageManager.PERMISSION_GRANTED) == PackageManager.PERMISSION_GRANTED) "granted" else "not granted"
        Log.d("Foo", "Package ${pkg.packageName} wants BIND_ACCESSIBILITY_SERVICE, and it is currently $grantStatus.")
    }
}

但是，對於無障礙服務，您可能需要查詢AccessibilityManager ：

val accessibilityManager = getSystemService(Context.ACCESSIBILITY_SERVICE) as AccessibilityManager
val installedServices = accessibilityManager.installedAccessibilityServiceList
val enabledServices = accessibilityManager.getEnabledAccessibilityServiceList(AccessibilityServiceInfo.FEEDBACK_ALL_MASK)
installedServices.forEach { installed ->
    val svcInfo = installed.resolveInfo.serviceInfo
    val appLabel = packageManager.getApplicationLabel(packageManager.getApplicationInfo(svcInfo.packageName, 0))
    val state = if (enabledServices.any { it.resolveInfo.serviceInfo.packageName == svcInfo.packageName && it.resolveInfo.serviceInfo.name == svcInfo.name && svcInfo.permission == Manifest.permission.BIND_ACCESSIBILITY_SERVICE)) {
        "enabled"
    } else {
        "installed but currently disabled"
    }
    Log.d("Foo", "Service ${svcInfo.name} belonging to $appLabel is $state.")
}

檢查可訪問性是否打開/關閉

(requireActivity().getSystemService(Context.ACCESSIBILITY_SERVICE) as AccessibilityManager).apply {
    installedAccessibilityServiceList.forEach { installedService ->
        installedService.resolveInfo.serviceInfo.apply {
            if (getEnabledAccessibilityServiceList(AccessibilityServiceInfo.FEEDBACK_ALL_MASK).any { it.resolveInfo.serviceInfo.packageName == packageName && it.resolveInfo.serviceInfo.name == name && permission == Manifest.permission.BIND_ACCESSIBILITY_SERVICE && it.resolveInfo.serviceInfo.packageName == requireActivity().packageName })
                isAccessibilityEnabled = true
        }
    } }
