android - Wake up device programmatically -


i want wake , unlock device. then, i'd show activity when user has new message firebase.

i wrote on onresume() method:

window = this.getwindow(); window.addflags(windowmanager.layoutparams.flag_show_when_locked | windowmanager.layoutparams.flag_dismiss_keyguard); window.addflags(windowmanager.layoutparams.flag_keep_screen_on | windowmanager.layoutparams.flag_turn_screen_on);

this works devices api > 19. problem in kitkat, either nothing or wakes screen doesn't unlock device.

also set right permissions in androidmanifest.xml:

<uses-permission android:name="android.permission.receive_boot_completed" /> <uses-permission android:name="android.permission.wake_lock" /> <uses-permission android:name="android.permission.disable_keyguard" />

also in myfirebasemessagingservice.class, i'm starting activity flag_activity_new_task flag.

does know missing?

thanks help.

ok found it. add piece of code , worked

keyguardmanager manager = (keyguardmanager) this.getsystemservice(context.keyguard_service); keyguardmanager.keyguardlock lock = manager.newkeyguardlock("abc"); lock.disablekeyguard();
