整體思路
需要在系統contacts中預置一個特定的聯系人，我們這裡采用的大體思路是：android啟動後會先啟動 launch ，是以我們就在launch裡面來向contacts中插入我們需要預置的資訊。
具體實作流程
- LINUX/android/packages/apps/Trebuchet/src/com/android/launcher3/Launcher.java 在onCreate 方法裡面加入以下代碼，啟動一個service
super.onCreate(savedInstanceState);
+ startService(new Intent(this, ImportDefaultContacts.class));
initializeDynamicGrid(false);
mHideIconLabels = SettingsProvider.getBoolean(this,
- 再來看看這個service LINUX/android/packages/apps/Trebuchet/src/com /android/launcher3/ImportDefaultContacts.java
+package com.android.launcher3;

+ return id;
+ }

+ }
+}
- 當然還需要相關的權限申請LINUX/android/packages/apps /Trebuchet/AndroidManifest.xml
<uses-permission android:name="cyanogenmod.permission.PROTECTED_APP" />
+ <uses-permission android:name="android.permission.READ_CONTACTS" />
+ <uses-permission android:name="android.permission.WRITE_CONTACTS" />
<application
android:name="com.android.launcher3.LauncherApplication"
@@ -, +, @@
<meta-data android:name="android.nfc.disable_beam_default"
android:value="true" />
+ <service android:name="com.android.launcher3.ImportDefaultContacts"></service>
</application>
說明
上面的代碼比較容易了解，都是對contacts資料庫的操作，這裡需要說明的是，android M 上面資料庫預設沒有了raw_contact_is_read_only這個列了，是以上面的
values.put("raw_contact_is_read_only", );
對于M上是沒有效果的。
