Android-programmatically bypass remove default lock screen

问题

I've defined a default application as a launcher with a HOME intent so it always runs when I boot the device. But I still see the default lock screen(with clock) first when I power up.

Is there a way to remove the lock screen entirely when the device powers up?

回答1:

Using following command you can disable the existing lockscreen of course if it doesn't contain any security(like patterns and pin code):

KeyguardManager keyguardManager = (KeyguardManager)getSystemService(Activity.KEYGUARD_SERVICE);
KeyguardLock lock = keyguardManager.newKeyguardLock(KEYGUARD_SERVICE);
lock.disableKeyguard();

you need also to declare permission in manifest:

<uses-permission android:name="android.permission.DISABLE_KEYGUARD"/>

Than detect the user presence (clicking on Power Button):

<receiver android:name=".Receive">
    <intent-filter android:enabled="true" android:exported="false">
        <action android:name="android.intent.action.USER_PRESENT" />
    </intent-filter>
</receiver>

and start custom lockscreen Activity
