Android 10 默认授权安装app运行时权限(去掉运行时所有权限授权弹窗)

GRANT_INSTALL就是在安装apk时已经给予了所有申请权限，所以运行时给与权限改为安装时给予权限就可以了。
解决方案如下：
在PermissionManagerService.java文件中restorePermissionState方法中将应用权限设置为安装权限

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

final String perm = bp.getName();
boolean allowedSig = false;
int grant = GRANT_DENIED;

// Keep track of app op permissions.
if (bp.isAppOp()) {
mSettings.addAppOpPackage(perm, pkg.packageName);
}

public class PermissionManagerService {
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.
// Before Q we represented some runtime permissions as install permissions,
// in Q we cannot do this anymore. Hence upgrade them all.
- grant = GRANT_UPGRADE;
+ grant = GRANT_INSTALL;
} else {
// For modern apps keep runtime permissions unchanged.
//grant = GRANT_RUNTIME;
