预置系统contacts

整体思路

需要在系统contacts中预置一个特定的联系人，我们这里采用的大体思路是：android启动后会先启动 launch ，所以我们就在launch里面来向contacts中插入我们需要预置的信息。

具体实现流程

• LINUX/android/packages/apps/Trebuchet/src/com/android/launcher3/Launcher.java 在onCreate 方法里面加入以下代码，启动一个service

         super.onCreate(savedInstanceState);
+        startService(new Intent(this, ImportDefaultContacts.class));
         initializeDynamicGrid(false);

         mHideIconLabels = SettingsProvider.getBoolean(this,

• 再来看看这个service LINUX/android/packages/apps/Trebuchet/src/com /android/launcher3/ImportDefaultContacts.java

• 当然还需要相关的权限申请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"
@@ -229,5 +231,6 @@

         <meta-data android:name="android.nfc.disable_beam_default"
                        android:value="true" />
+        <service android:name="com.android.launcher3.ImportDefaultContacts"></service>
     </application>

说明

上面的代码比较容易理解，都是对contacts数据库的操作，这里需要说明的是，android M 上面数据库默认没有了raw_contact_is_read_only这个列了，所以上面的

values.put("raw_contact_is_read_only", 1);

对于M上是没有效果的。
