Android16 给应用默认获取权限

不急不躁1232025-12-26 16:26

修改点在

/frameworks/base/services/core/java/com/android/server/pm/permission/DefaultPermissionGrantPolicy.java

在grantDefaultSystemHandlerPermissions方法里面可以看到有很多默认获取权限的代码，在这里添加即可如：

复制代码

	  //add by xxx begin
      PackageInfo miniscreenPackageInfo = pm != null ? pm.getSystemPackageInfo("需要添加权限应用的包名") : null;
      if (miniscreenPackageInfo != null
              && doesPackageSupportRuntimePermissions(miniscreenPackageInfo)) { 
          grantPermissionsToSystemPackage(pm, "需要添加权限应用的包名",
                  userId, FOREGROUND_LOCATION_PERMISSIONS);
      }
      //add by xxx end

这样修改会引起GMS问题，需要在/frameworks/base/core/java/android/app/ApplicationPackageManager.java的checkPermission方法里面同步修改

复制代码

    @Override
    public int checkPermission(String permName, String pkgName) {
        //add by xxx for grant permission begin
        String taker = mContext.getPackageName();
        if ("com.google.android.permission.gts".equals(taker)) {
            if("需要添加权限应用的包名".equals(pkgName)){
                return PERMISSION_DENIED;
            }
        }
        //add by xxx,for grant permission end
        return PermissionManager.checkPackageNamePermission(permName, pkgName, getUserId());
    }
