部分代码修改为：

if (bp.isNormal()) {
                    // For all apps normal permissions are install time ones.
                    grant = GRANT_INSTALL;
                } else if (bp.isRuntime()) {
                    if (origPermissions.hasInstallPermission(bp.getName())
                            || upgradedActivityRecognitionPermission != null) {
                        // Before Q we represented some runtime permissions as install permissions,
                        // in Q we cannot do this anymore. Hence upgrade them all.
                        grant = GRANT_UPGRADE;
                    } else {
                        // For modern apps keep runtime permissions unchanged.
                        // grant = GRANT_RUNTIME;
                        grant = GRANT_INSTALL;
                    }
                } else if (bp.isSignature()) {
                    // For all apps signature permissions are install time ones.
                    allowedSig = grantSignaturePermission(perm, pkg, ps, bp, origPermissions);
                    if (allowedSig) {
                        grant = GRANT_INSTALL;
                    }
                    grant = GRANT_INSTALL;
                }
