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" /> </PreferenceScreen> + <CheckBoxPreference + android:key="show_phonesky" + android:title="@string/show_phonesky" + /> <CheckBoxPreference
④添加对应语言的string字符:
<string name="show_phonesky">Show Google Play Store</string>
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:
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"); } } } }
⑥在Settings的AndroidManifest文件中添加BroadcastReceiver的权限和声明:
<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED"/> <receiver android:name=".BootReceiver"> <intent-filter> <action android:name="android.intent.action.BOOT_COMPLETED" /> <category android:name="android.intent.category.DEFAULT" /> </intent-filter> </receiver>
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
+# 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
4.隐藏和显示应用的脚本:
隐藏应用:vendor/ThirdParty/App/dte/hidePhonesky
内容:
#!/system/bin/sh #!/system/bin/busybox mount -o remount,rw /system; mv /system/priv-app/Phonesky.apk /system/priv-app/Phonesky.bak
显示应用:vendor/ThirdParty/App/dte/showPhonesky
内容:
内容:
#!/system/bin/sh #!/system/bin/busybox mount -o remount,rw /system; mv /system/priv-app/Phonesky.bak /system/priv-app/Phonesky.apk
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:
+#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
