可以看出，mDeviceProvisioned 的值不同,因此KeyguardViewMediator.java中的处理也不同。

源码位置：SystemUI/src/com/android/systemui/keyguard/KeyguardViewMediator.java

private void doKeyguardLocked(Bundle options) {
		...
	 if (!lockedOrMissing && shouldWaitForProvisioning() && !antiTheftLocked) {
         if (DEBUG) Log.d(TAG, "doKeyguard: not showing because device isn't provisioned"
                  + " and the sim is not locked or missing");
         return;
     }	
     	...
}
		...
private boolean shouldWaitForProvisioning() {
     return !mUpdateMonitor.isDeviceProvisioned() && !isSecure();
}

源码位置：SystemUI/src/com/android/keyguard/KeyguardUpdateMonitor.java

public boolean isDeviceProvisioned() {
    if (mDeviceProvisioned == false) {
        Log.d(TAG, "isDeviceProvisioned get DEVICE_PROVISIONED from db again !!");
        return (0 != Settings.Global.getInt(
                mContext.getContentResolver(), Settings.Global.DEVICE_PROVISIONED, 0));
    } else {
        return mDeviceProvisioned;
    }
}
		...
mDeviceProvisioned = isDeviceProvisionedInSettingsDb();
		...
private boolean isDeviceProvisionedInSettingsDb() {
    return Settings.Global.getInt(mContext.getContentResolver(),
               Settings.Global.DEVICE_PROVISIONED, 0) != 0;
}

DefaultActivity.java中

  Settings.Global.putInt(getContentResolver(), Settings.Global.DEVICE_PROVISIONED, 1);
  Settings.Secure.putInt(getContentResolver(), Settings.Secure.USER_SETUP_COMPLETE, 1);
  只设置这两个属性后就finish了，没有最其他操作，闪现白色界面就是启动这个了
