How to profile "native code" in android

I am using AndroidStudio 1.2

I tried to profile my own code in android with a link to SOLUTION in this link, where I tried to figure out the use of aprof, even if I make the necessary settings → giving write permission by adding config in android.mk, as in a solution that the file does not get in / mnt / sdcard below, my code ..

AndroidManifest.xml

<?xml version="1.0" encoding="utf-8"?>

<application
    android:allowBackup="true"
    android:icon="@mipmap/ic_launcher"
    android:label="@string/app_name"
    android:theme="@style/AppTheme" >
    <activity
        android:name=".MainActivity"
        android:label="@string/app_name" >
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
    <activity
        android:name=".DisplayMemory"
        android:label="@string/title_activity_display_memory" >
    </activity>
    <activity
        android:name=".DisplayCpu"
        android:label="@string/title_activity_display_cpu" >
    </activity>
    <activity
        android:name=".BatteryInfo"
        android:label="@string/title_activity_battery_info" >
    </activity>
    <activity
        android:name=".TrafficAnalysis"
        android:label="@string/title_activity_traffic_analysis" >
    </activity>
</application>
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

Android.mk

LOCAL_ENABLE_APROF := true
LOCAL_PATH := $(call my-dir)
include $(CLEAR_VARS)
LOCAL_SRC_FILES := CalcNative.c
LOCAL_MODULE := CalcNative
LOCAL_LDLIBS := -llog
LOCAL_ENABLE_APROF_JNI := true
include $(BUILD_SHARED_LIBRARY)

My screenshot is the file of my file where the aprof file is not displayed
