Fingerprint interface

simple description

• Fingerprint power interface

1. method

• EnableFingerpint(String key,boolean enable);

Call method

• SystemProperties.EnableFingerpint(String key,boolean enable);

parameter

parameter name	necessary	type	Description
key	yes	string	The key value of the corresponding module
enable	yes	boolean	power on or off

Call example (to facilitate third-party application calls, use reflection to obtain SystemProperties)

    setEnable("finger",true);  "finger" is fingerprint KEY

    public static void setEnable(final String key, final boolean def) {
        try {
            if (getinfor == null) {
                getinfor = Class.forName("android.os.SystemProperties")
                        .getMethod("EnableFingerpint", String.class,boolean.class);
            }
             getinfor.invoke(null, key,def) ;
        } catch (Exception e) {
           e.printStackTrace();
        }
    }

2 .Get module status interface

method

• ReadFingerpint(String key);

Call method

• SystemProperties.ReadFingerpint(String key);

parameter name	necessary	type	Description
key	yes	string	The key value of the corresponding module

Call example (to facilitate third-party application calls, use reflection to obtain SystemProperties)

   int statu = test("finger","-1")  "finger" is fingerprint KEY

   public static String test(final String key,String def) {
        try {

            if (Getfingerpint == null) {
                Getfingerpint = Class.forName("android.os.SystemProperties")
                        .getMethod("ReadFingerpint", String.class);
            }
            return ((String) Getfingerpint.invoke(null, key)).toString();
        } catch (Exception e) {
             e.printStackTrace();
        }
        return  def;
    }

Return parameter description

parameter name	type	Description
