我正在制作一款Android应用,用于测试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,或者您的手机上的数据已加密。
由于某种原因,应用程序必须运行两次才能测试并查看是否在手机上启用了这些安全功能,这是我正在尝试解决的问题。我希望它能够测试并查看在创建应用程序时以及第一次运行应用程序时是否启用了安全功能,而不是第二次运行应用程序。
我测试onStart()
文件中的MainActivity
函数是否启用了这些功能。我在下面列出了函数代码:
@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,谢谢你的帮助。也许这个问题与super.onStart();
有人认为启动加载屏幕可能有助于解决问题吗?
