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：

?

1 2 3

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

②CheckBox的逻辑：

?

1 2 3 4 5 6 7 8 9

(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> <br> <br> <br> <br>
