场景：
Settings应用的界面，拉起Dialer的界面报错。
问题描述：
//Fail log：Settings->ApnEditorActivity
01-11 16:46:07.938 1044 6380 W ActivityTaskManager: Permission Denial: package=com.android.settings does not belong to uid=1001
//Pass log: Settings->ApnSettingsActivity
01-11 16:46:03.997 1044 1694 I ActivityTaskManager: START u0 {act=android.intent.action.CALL_BUTTON flg=0x10000000 cmp=com.android.dialer/.app.DialpadActivity} from uid 1000
UI对应的进程配置
<!--AndroidManifest.xml-->
<activity?android:name="Settings$ApnEditorActivity"
android:process="com.android.phone">
原因分析：
UI在com.android.settings, 配置了android:process="com.android.phone",两者处于不同的进程。
源码参考：xref: /packages/apps/Settings/AndroidManifest.xml?(revision 939136b)
<!--xref: /packages/apps/Settings/AndroidManifest.xml (revision 939136b3)-->
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
? ? ? ? xmlns:androidprv="http://schemas.android.com/apk/prv/res/android"
? ? ? ? package="com.android.settings"
? ? ? ? coreApp="true"
? ? ? ? android:sharedUserId="android.uid.system">
Settings应用处于system，phone属于radio
adb shell
top # 查看进程信息
// top 部分结果

解决方案：
根据日志?ActivityTaskManager: Permission Denial: package=com.android.settings does not belong to uid=1001，应该是包与进程不匹配。去掉android:process="com.android.phone"配置。
