Android使用init.rc触发脚本实现隐藏内置应用

【实现逻辑】 通过在property_service.c中设置标志位，在设置中实现接口改变标志位， 使用init.rc中声明的服务来侦听标志位的变化，显式启动声明的服务，执行对应的脚本，把应用后缀从apk重命名为bak，从而实现隐藏（显示逻辑相反）。
【实现步骤】以隐藏Google Play Store（system/priv-app/Phonesky.apk）为例： 1.首先在system/core/init/property_service.c中声明并初始化标志位，0为隐藏，1为显示，默认隐藏

     { app.launcher.start, AID_SYSTEM, 0},
+   { app.phonesky.show, AID_SYSTEM, 0}, //Add By zj
     { cdma.,        AID_RADIO,    0 },    //Add by gfzhu VIA



2.在设置的开发者选项中实现对应的接口： 文件路径：packages/apps/Settings/src/com/android/settings/DevelopmentSettings.java ①声明和初始化：

?

private static final String SHOW_PHONESKY = show_phonesky;
private CheckBoxPreference mShowPhonesky;
mShowPhonesky = findAndInitCheckboxPref(SHOW_PHONESKY);


②CheckBox的逻辑：

       (BatteryManager.BATTERY_PLUGGED_AC | BatteryManager.BATTERY_PLUGGED_USB) : 0);
+      } else if (preference == mShowPhonesky) { // ZJ Add
+           if(mShowPhonesky.isChecked())
+           {
+              SystemProperties.set(app.phonesky.show,1);
+           }else{
+              SystemProperties.set(app.phonesky.show,0);
+           }
         } else if (preference == mBtHciSnoopLog) {




③增加一个Preference： packages/apps/Settings/res/xml/development_prefs.xml

     android:targetClass=com.android.settings.SetFullBackupPassword />
      
+       <checkboxpreference android:key="show_phonesky" android:title="@string/show_phonesky">
     <checkboxpreference pre="">
 
 
 
 
④添加对应语言的string字符：<pre class="brush:java;"><string name="show_phonesky">Show Google Play Store</string></pre>
<br>
<br>
⑤设置中新增一个监听，初始化Checkbox的逻辑： packages/apps/Settings/src/com/android/settings/BootReceiver.java 内容如下：
<pre class="brush:java;">package com.android.settings;
 
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.content.SharedPreferences;
import android.os.SystemClock;
import android.util.Log;
import android.os.SystemProperties;
 
public class BootReceiver extends BroadcastReceiver{
 
     @Override
     public void onReceive(Context arg0, Intent arg1) {
          // TODO Auto-generated method stub
           
          String action = arg1.getAction();
          if(action.equals(Intent.ACTION_BOOT_COMPLETED))
          {
             SharedPreferences shared = arg0.getSharedPreferences(com.android.settings_preferences, Context.MODE_PRIVATE);
             boolean show_phonesky = shared.getBoolean(show_phonesky, false);
             if(show_phonesky){
                  SystemProperties.set(app.phonesky.show,1);    
               }else{
                    SystemProperties.set(app.phonesky.show,0);    
               }
          }
     }
}</pre>
<br>
<br>
⑥在Settings的AndroidManifest文件中添加BroadcastReceiver的权限和声明：
<pre class="brush:java;"><uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED/">
</uses-permission></pre>
<br>
3.在init.rc中添加对应的服务和触发条件： 路径：mediatek/config/esky27_tb_ccn_mlc_kk/init.rc
<pre class="brush:java;">+# ZJ Add START
+#Hide or Show Google Play Dynamicly
+#disabled:服务不会自动运行，必须显式地通过服务器来启动。
+#oneshot:当此服务退出时不会自动重启。
+service hidePhonesky /system/bin/hidePhonesky
+       disabled
+       oneshot   
+service showPhonesky /system/bin/showPhonesky
+       disabled
+       oneshot   
+#on property:sys.boot_completed=1
+#   start renamePhonesky
+on property:app.phonesky.show=1
+   start showPhonesky
+on property:app.phonesky.show=0
+   start hidePhonesky
+# ZJ Add END</pre>
<br>
<br>
4.隐藏和显示应用的脚本： 隐藏应用：vendor/ThirdParty/App/dte/hidePhonesky 内容：<br>
<pre class="brush:java;">#!/system/bin/sh
#!/system/bin/busybox
mount -o remount,rw /system;
mv /system/priv-app/Phonesky.apk /system/priv-app/Phonesky.bak</pre>
<br>
显示应用：vendor/ThirdParty/App/dte/showPhonesky<br>
内容：<br>
<pre class="brush:java;">#!/system/bin/sh
#!/system/bin/busybox
mount -o remount,rw /system;
mv /system/priv-app/Phonesky.bak /system/priv-app/Phonesky.apk</pre>
<br>
<br>
5.拷贝脚本到system/bin目录下： 参考以下格式添加到对应的mk文件：
<pre class="brush:java;">+#添加重命名GooglePlay脚本
+PRODUCT_COPY_FILES +=
+       vendor/ThirdParty/App/dte/hidePhonesky:system/bin/hidePhonesky
+       vendor/ThirdParty/App/dte/showPhonesky:system/bin/showPhonesky
+       vendor/ThirdParty/App/dte/Phonesky.bak:system/priv-app/Phonesky.bak</pre>
</checkboxpreference></checkboxpreference><br>
