It must be unsuppressed if it is // not the selectedsecurity method for the following reason: if the user starts //without a screen lock selected, the biometric unlock would besuppressed the first // time they try to use it. // // Note thatthe biometric unlock will still not show if it is not the selectedmethod. // Calling setAlternateUnlockEnabled(true) simply saysdon't suppress it if it is the // selected method.

if (mLockPatternUtils.usingBiometricWeak()&& mLockPatternUtils.isBiometricWeakInstalled()) {

if (DEBUG) Log.d(TAG, "suppressing biometric unlock duringboot"); mUpdateMonitor.setAlternateUnlockEnabled(false);

} else {

mUpdateMonitor.setAlternateUnlockEnabled(true);

}

doKeyguardLocked();

} // Most services aren't available until the system reaches theready state, so we // send it here when the device first boots.

maybeSendUserPresentBroadcast();

}

把doKeyguardLocked();注释掉，重新编译系统，你开机就不会进入锁屏界面了。
