最近，客戶提出一個需求，要加設備中加入VVM相關。
VVM配置：
客戶提供了一個VVM配置信息，如下：.
Orange France (208/01)
Type : vvm_type_omtp
Dest Number : 21101
Dest port : 20481
vvm package : com.orange.vvm
prefetch : true
cellular data : true
ssl port : 0
legacy mode : false
disabled capabilities : STARTTLS
client prefix: //VVM
配置的信息，主要包含於Package/apps/CarrierConfig中，具體配置爲：
packages/apps/CarrierConfig/assets/carrier_config_20801.xml
<!--Visual voicemail config-->
<!--VVM Type-->
<string name="vvm_type_string">vvm_type_omtp</string>
<!--VVM Dest Number-->
<string name="vvm_destination_number_string">21101</string>
<!--VVM Dest port-->
<int name="vvm_port_number_int" value="20481"/>
<!--VVM package-->
<string-array name="carrier_vvm_package_name_string_array" num="1">
<item value="com.orange.vvm"/>
</string-array>
<!--VVM prefetch-->
<boolean name="vvm_prefetch_bool" value="true"/>
<!--VVM cellular data-->
<boolean name="vvm_cellular_data_required_bool" value="true"/>
<!--VVM ssl port-->
<int name="vvm_ssl_port_number_int" value="0"/>
<!--VVM legacy mode-->
<boolean name="vvm_legacy_mode_enabled_bool" value="false"/>
<!--VVM disabled capabilities-->
<string-array name="vvm_disabled_capabilities_string_array" num="1">
<item value="STARTTLS"/>
</string-array>
<!--VVM client prefix-->
<string name="vvm_client_prefix_string">//VVM</string>
配置完成後，插入對應Orange SIM卡後，運行正常。
經由客戶測試後，反饋一個bug，安裝運營商的VVM應用後，原生VVM自動禁用，但是卸載VVM後，原生代碼沒有自動開啓。
查看對應的代碼，發現目前只對應用的安裝進行了監聽，並未對應用卸載進行監聽，具體如下：
packages/services/Telephony/src/com/android/phone/vvm/CarrierVvmPackageInstalledReceiver.java
public void register(Context context) {
IntentFilter intentFilter = new IntentFilter(Intent.ACTION_PACKAGE_ADDED);
intentFilter.addDataScheme("package");
context.registerReceiver(this, intentFilter);
}
對應的處理類中，也只對安裝進行了處理，具體如下：
packages/apps/Dialer/java/com/android/voicemail/impl/VvmPackageInstallHandler.java
public static void handlePackageInstalled(Context context, String packageName) {...}
因此我們只需加入對應的處理即可，修改代碼如下：
packages/services/Telephony/src/com/android/phone/vvm/CarrierVvmPackageInstalledReceiver.java
+ private static final String ACTION_CARRIER_VVM_PACKAGE_UNINSTALLED =
+ "com.android.internal.telephony.CARRIER_VVM_PACKAGE_UNINSTALLED";

}
