我正在制作一个 android 应用程序来测试您手机上的某些安全功能是否已启用。例如,如果您启用了密码登录,或者您的数据在手机上已加密。
出于某种原因,该应用程序必须运行两次以测试手机是否启用了这些安全功能,这就是我要解决的问题。我希望它测试并查看在创建应用程序和第一次运行应用程序时是否启用了安全功能,而不是第二次运行它。
我测试是否onStart()
在我的MainActivity
文件中的函数中启用了这些功能。我包括下面的功能代码:
@Override
@TargetApi(Build.VERSION_CODES.JELLY_BEAN_MR1)
@SuppressLint("NewApi")
public void onStart()
{
super.onStart();
//determine if phone uses lock pattern
//It returns 1 if pattern lock enabled and 0 if pin/password password enabled
ContentResolver cr = getBaseContext().getContentResolver();
lockPatternEnable = Settings.Secure.getInt(cr, Settings.Secure.LOCK_PATTERN_ENABLED, 0);//Settings.System
//returns 1 if pin/password protected. 0 if not
KeyguardManager keyguardManager = (KeyguardManager) getBaseContext().getSystemService(Context.KEYGUARD_SERVICE);
if( keyguardManager.isKeyguardSecure())
{
//it is pin or password protected
pinPasswordEnable=1;
}
else
{
//it is not pin or password protected
pinPasswordEnable=0;
}//http://stackoverflow.com/questions/6588969/device-password-in-android-is-existing-or-not/18716253#18716253
//determine if adb is enabled. works
adb=Settings.Global.getInt(cr, Settings.Global.ADB_ENABLED, 0);
//determine if bluetooth is enabled.works
bluetooth=Settings.Global.getInt(cr, Settings.Global.BLUETOOTH_ON, 0);
//Settings.System BLUETOOTH_DISCOVERABILITY
//determine if wifi is enabled. works
WifiManager wifi = (WifiManager)getSystemService(Context.WIFI_SERVICE);
if (wifi.isWifiEnabled())
{
//wifi is enabled
wifiInt=1;
}
else
wifiInt=0;
//determine if data is encrypted
getDeviceEncryptionencryption();
//determine if gps enabled
}//end of onStart() function
如果需要发布更多代码来回答这个问题,请告诉我,感谢您的帮助。也许这个问题与super.onStart();
有没有人认为启动加载屏幕可能有助于解决问题?
