如何检查其他应用程序是否在 Android 中使用辅助功能 (BIND_ACCESSIBILITY_SERVICE) 权限

问题描述

如何检查是否有任何应用程序使用了无障碍权限（BIND_ACCESSIBILITY_SERVICE），或者请求相同的应用程序的名称以及是否授予它们？

检测以下应用正在使用无障碍权​​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

已尝试以下代码不适用于上述应用程序，未显示 Access Dot 应用程序和 BurnerGuard 应用程序的任何条目，同时显示最后一次通过的条目但不影响权限更改：

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;
            }
    }

谢谢

解决方法

对于一般权限（在清单中使用 <uses-permission> 声明的权限），这应该为您提供所需的信息：

// 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，对于无障碍服务，您可能需要改为查询 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.")
}
