在调用操作\调用意图时解锁android设备不工作

我收到一个推送通知，在这方面，调用前台服务

从服务中，我调用一个活动

在这里，我有两个功能

1。紧急情况下的声音警报

2。使用行动呼叫。

如果设备解锁，两者都可以正常工作

但是，如果一个设备被密码或模式锁定，当push接收时，它不工作

下面是解锁设备的代码。此方法是从启动时调用的

private void unlockDevice() {

    KeyguardManager loKeyguardManager = (KeyguardManager) getSystemService(Context.KEYGUARD_SERVICE);
    Window loWindow = this.getWindow();

    if (Common.isAboveAPI27()) {
        setShowWhenLocked(true);
        setTurnScreenOn(true);
    } else if (Common.isAboveAPI26()) {
        loWindow.addFlags(WindowManager.LayoutParams.FLAG_SHOW_WHEN_LOCKED);
        loWindow.addFlags(WindowManager.LayoutParams.FLAG_TURN_SCREEN_ON);
        dismissKeyguard(loKeyguardManager);
    } else {
        if (loKeyguardManager != null) {
            KeyguardManager.KeyguardLock loKeyguardLock = loKeyguardManager.newKeyguardLock("FullWakeUps");
            loKeyguardLock.disableKeyguard();
        }
        loWindow.addFlags(WindowManager.LayoutParams.FLAG_DISMISS_KEYGUARD); // Deprecated in 26
        loWindow.addFlags(WindowManager.LayoutParams.FLAG_SHOW_WHEN_LOCKED); // Deprecated in 27
        loWindow.addFlags(WindowManager.LayoutParams.FLAG_TURN_SCREEN_ON); // Deprecated in 27
    }

    //Keep screen on
    loWindow.addFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON);
}

@RequiresApi(api = Build.VERSION_CODES.O)
private void dismissKeyguard(KeyguardManager loKeyguardManager) {
    if (loKeyguardManager != null) {
        loKeyguardManager.requestDismissKeyguard(SOSCallAndAlarmActivity.this, new KeyguardManager.KeyguardDismissCallback() {
            @Override
            public void onDismissError() {
                super.onDismissError();
                Log.i(TAG, Build.VERSION.SDK_INT + " : onDismissError");
            }

            @Override
            public void onDismissSucceeded() {
                super.onDismissSucceeded();
                Log.i(TAG, Build.VERSION.SDK_INT + " : onDismissSucceeded");
            }

            @Override
            public void onDismissCancelled() {
                super.onDismissCancelled();
                Log.i(TAG, Build.VERSION.SDK_INT + " : onDismissCancelled");
            }
        });
    }
}

在onDestroy中调用以下方法以重新启用锁：

private void reEnabledKeyguard() {
    KeyguardManager loKeyguardManager = (KeyguardManager) getSystemService(Context.KEYGUARD_SERVICE);
    if (loKeyguardManager != null) {
        KeyguardManager.KeyguardLock loKeyguardLock = loKeyguardManager.newKeyguardLock("FullWakeUps");
        loKeyguardLock.reenableKeyguard();
    }
    Window loWindow = this.getWindow();
    loWindow.addFlags(WindowManager.LayoutParams.FLAG_ALLOW_LOCK_WHILE_SCREEN_ON);
}

启动呼叫的代码

public void callOnNumbers(String fsPhoneNumber) {
    Intent loCallIntent = new Intent(Intent.ACTION_CALL);
    loCallIntent.setData(Uri.parse("tel:" + fsPhoneNumber));
    //callIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK); // tried this but not helped.
    if (ActivityCompat.checkSelfPermission(CallAndAlarmActivity.this,
            android.Manifest.permission.CALL_PHONE) != PackageManager.PERMISSION_GRANTED) {
        Log.i(TAG, "call phone permission not granted");
        return;
    }
    startActivity(loCallIntent);
}

奇怪的是，当这种方法打开呼叫屏幕闪烁，并再次在锁定屏幕上显示密码屏幕时，只需按下后退按钮，我就可以看到呼叫屏幕

我还需要知道一件事，即使我设置了所有应用程序终止选项并禁用了电池优化。推送接收时未执行相同的代码

当设备处于非活动状态半小时后，如果push接收到，上述代码甚至没有亮起灯。当我点击锁定/解锁按钮时，我可以正确地看到我的屏幕。即使我在30秒的推送时间后按下它

安卓N面临的问题

附加的 当ACTION\u CALL intent调用它来执行我的活动

onPause

时，我没有在

onPause

中添加任何代码，我可以在

logcate

谢谢

我想知道这是否与Android中的后台执行限制有关。。我建议大家看看这篇文章

我希望这能有所帮助。

谢谢您的输入，但我已经在“设置”中列出了我的应用程序的白名单。
