通过android 系统编译自己的app，用于控制hal

系统app 是在 Z:\\itop-3399_8.1\\packages\\apps 这个路径下
在Z:\\itop-3399_8.1\\packages\\apps 创建 HelloWorld
HelloWorld 下创建res、src文件夹，以及 Android.mk
将Android studio 中或则 eclipse 中生成的AndroidManifest.xml 拷贝过来

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
   package="com.example.myapplication">

   <application
       android:allowBackup="true"
       android:icon="@mipmap/ic_launcher"
       android:label="@string/app_name"
       android:roundIcon="@mipmap/ic_launcher_round"
       android:supportsRtl="true"
       >
       <activity
           android:name="com.example.myapplication.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>
   </application>

</manifest>

Android.mk

LOCAL_PATH:= $(call my-dir)
include $(CLEAR_VARS)

LOCAL_MODULE_TAGS := optional

LOCAL_SRC_FILES := $(call all-java-files-under, src)

LOCAL_PACKAGE_NAME := HelloWorld

LOCAL_CERTIFICATE := platform
#LOCAL_PRIVILEGED_MODULE := true

include $(BUILD_PACKAGE)

# Use the following include to make our test apk.
include $(call all-makefiles-under,$(LOCAL_PATH))

res 文件

HelloWorld文件的结构图

将Android studio下和 eclipse 下的 res 拷贝过来
我的只对stirng.xml 做了修改

<resources>
    <string name="app_name">My Application</string>
    <string name="action_settings">Settings</string>
    <!-- Strings used for fragments for navigation -->
    <string name="first_fragment_label">First Fragment</string>
    <string name="second_fragment_label">Second Fragment</string>
    <string name="next">Next</string>
    <string name="previous">Previous</string>

    <string name="hello_first_fragment">Hello first fragment</string>
    <string name="hello_second_fragment">Hello second fragment. Arg: %1$s</string>
    <string name="add">相加</string>
    <string name="server_name">hello_world_service</string>
	<string name="init">初始化</string>
</resources>

src 中 MainActivity.java 文件

package com.example.myapplication;

import android.app.Activity;
import android.os.Bundle;
import android.app.HelloWorldServiceManger;
import android.util.Log;
import android.view.View;
import android.widget.TextView;

public class MainActivity extends Activity {

    private TextView tvResult;
    private int result;
    private boolean isInit;
    public static final String TAG = "hello_world_activity";

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        tvResult = findViewById(R.id.tv_result);
        findViewById(R.id.btn).setOnClickListener(new View.OnClickListener() {

            @Override
            public void onClick(View v) {
                HelloWorldServiceManger service = (HelloWorldServiceManger) getSystemService(getString(R.string.server_name));
                isInit = service.init();
                if (isInit) {
                    Log.d(TAG, "onClick: 成功");
                } else {
                    Log.d(TAG, "onClick: 失败");
                }
            }
        });
        findViewById(R.id.btn1).setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {

                HelloWorldServiceManger service = (HelloWorldServiceManger) getSystemService(getString(R.string.server_name));
                result = service.addVal(3, 4);
                tvResult.setText("addVal" + result);
            }
        });


    }
}
