addProximityAlert在api 4及以下版本的android 4及以下版本上不支持api 17及更高版本，并进入接收方广播 但api 17及以上版本不起作用 我添加了FINE_LOCATION权限 我的应用检查用户是否输入特定区域并在内部或外部触发通知并将其存储在数据库中

功能代码：

Locationmanager locationmanager = (Locationmanager) getSystemService(Context.LOCATION_SERVICE);
        Intent intent = new Intent("actION_PROXIMITY_ALERT");
        intent.putExtra("phone",phone);
        intent.putExtra("name",name);
        intent.putExtra("empnum",empnum);
        PendingIntent pendingIntent = PendingIntent.getBroadcast(this,intent,0);

        if (activityCompat.checkSelfPermission(this,Manifest.permission.accESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED && activityCompat.checkSelfPermission(this,Manifest.permission.accESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {

            String[] perm = {Manifest.permission.accESS_FINE_LOCATION};
            activityCompat.requestPermissions(this,perm,1);
        } else {
            Toast.makeText(this,"enter",Toast.LENGTH_SHORT).show();
            if (locationmanager != null) {
                locationmanager.addProximityAlert(28.0837576,30.7637102,50,-1,pendingIntent);
            }
        }
