How I can set file permissions in a custom project added to Android AOSP -


i add aosp device-owner app.

  1. create directory @ packages/apps/myapp
  2. copy myapp.apk , device-owner.xml packages/apps/myapp
  3. create android.mk:
local_path := $(call my-dir) include $(clear_vars) $(shell mkdir -p $(target_out_data)/system) $(shell cp $(local_path)/device_owner.xml $(target_out_data)/system) local_module_tags := optional local_module := myapp local_certificate := presigned local_privileged_module := true local_src_files :=  $(local_module).apk local_module_class := apps local_module_suffix := $(common_android_package_suffix) local_post_install_cmd := chown system:system $(target_out_data)/system/device_owner.xml include $(build_prebuilt)
  1. device-owner.xml
<?xml version='1.0' encoding='utf-8' standalone='yes' ?> <device-owner package="com.test.test.myapp" />
  1. after flash userdata.img device have permissions:

-rw-r--r-- root root 112 2016-09-22 06:29 device_owner.xml

but must have such after dpm set-device-owner com.test.test.myapp/.deviceadminreceiver

-rw------- system system 112 2016-09-22 06:29 device_owner.xml

how can set permissions /data/system/device-owner.xml via android.xml or way?

sorry if unclear - mean can modify permission of file in system/core/include/private/android_filesystem_config.h described here: http://paldan.altervista.org/dir-and-files-permissions-in-the-aosp-filesystem/?doing_wp_cron=1474724093.3321709632873535156250 or place device-owner.xml folder proper permissions

unity3d - Rotate an object to face an opposite direction -

i have object , b. when click on object b, rotates object b (a faces b). b doesn't face a. need following : when faces b, need face opposite direction. have code rotating @ b. how rotate face opposite direction after that? vector3 targetdirection = target - transform.position; float step = speed * time.deltatime; vector3 newdirection = vector3.rotatetowards (turretdome.transform.forward, targetdirection, step, 0.0f); turretdome.transform.rotation = quaternion.lookrotation (newdirection); you object facing object b, want inverse direction of object after that? objecta.transform.rotation = quaternion.inverse(objecta.transform.rotation) but lets assume example turretdome object a, (negate direction): turretdome.transform.rotation = quaternion.lookrotation (-newdirection); naturally, both of these snippets not show how smoothen rotation, seem know how use time.deltatime. just incase unsure, quaternion.lerp this

angular - Is it possible to get native element for formControl? -

i've got angular2 reactive form . created formcontrol s , assigned input fields by [formcontrol]=... . understand creates nativeelement <-> formcontrol link. my question: possible nativeelement formcontrol ? wanna myformcontrol.nativeelement.focus() i can share 1 terrible solution works me. in reactive forms can use either 1) formcontroldirective ts mycontrol = new formcontrol('') template <input type="text" [formcontrol]="mycontrol"> or 2) formcontrolname ts myform: formgroup; constructor(private fb: formbuilder) {} ngoninit() { this.myform = this.fb.group({ foo: '' }); } template <form [formgroup]="myform"> <input type="text" formcontrolname="foo"> </form> so these directives write patch like 1) formcontroldirective const originformcontrolngonchanges = formcontroldirective.prototype.ngonchanges; formcontroldirective.proto
