JS APIs and instructions

1. JS APIs function isScreenLocked(callback: AsyncCallback): void; query the screenlock status，callback mode function isScreenLocked(): Promise; void; query the screenlock status，Promise mode

function isSecureMode(callback: AsyncCallback): void; query whether to set screenlock password (gesture, digital password, pin, SIM)，callback mode function isSecureMode(): Promise; query whether to set screenlock password (gesture, digital password, pin, SIM)，Promise mode

function unlockScreen(callback: AsyncCallback): void; request unlockScreen，callback mode function unlockScreen(): Promise; request unlockScreen，Promise mode

2. JS APIs instructions // Import module import screenLock from '@ohos.screenLock';

// query the screenlock status asynchronously with a Promise screenLock.isScreenLocked()
.then((value) => {
console.log(success to screenLock.isScreenLocked: ${value});
}).catch((err) => {
console.error(failed to screenLock.isScreenLocked because ${err.message})
});

// query the screenlock status asynchronously with a callback screenLock.isScreenLocked((err, value) => {
if (err) {
console.error(failed to screenLock.isScreenLocked because ${err.message});
return;
}
console.log(success to screenLock.isScreenLocked: ${value});
});

Debugging method

1. Compile command

./build.sh --product-name (Fill in the specific product name, such as：Hi3516DV300) --build-target screenlock_native

2. push so file

in $root\out\ohos-arm-release\miscservices\screenlock_native，push libscreenlock_server.z.so libscreenlock_client.z.so libscreenlock_utils.z.so to system/lib，and push libscreenlockability.z.so to system/lib/module/app下.make sure the four so files is readable at least.

3. reboot
