Android uygulamam 4.4 altı çalışmıyor yardım

Merhaba arkadaşlar bir uygulama yaptım fakat sadece 4.4 ve üzeri çalışıyor. uygulamada 3 çeşit giriş var 2 giriş webview onlara sorunsuz giriyor. Fakat diğer giriş butonuna tıklayınca uygulama durduruldu hatası veriyor. O alanda facebook'a yönlendirip giriş yapmasını sağlıyor ve urlyi oto kopyalıyor. yardım edecek arkadaş varmı acaba ?

Hata logu var mı koyabilir misiniz?
Usb ile telefonu bağlayın editörü açın oraya log basar

muhtemelen API Level: 19 kullanıyorsunuz alt sürümleri seçip Export ederek deneyebilirsiniz

hta logu bu şekilde. uygulama açılıyor ama sadece java kod içeren facebook için olan yer (giris) de tek bu hata veriyor.

bu şekilde hocam

Hata Giris.java da 82.satırda
Giris javanın resmini koyar mısınız buraya 82 de görünecek sekilde

bu hocam.

ya tkn değişkeni ya da a değişkeni null dostum o sebeple crash oluyor app.
yani memoryde adreslenmemiş

Hocam rica etsem yardımcı olurmusunuz. Bir türlü yapamadım 4.4 altı çalışmıyor sadece

WebView'de getUrl() metodu null döndürüyor heralde. O an webview'de herhangi bir sayfa açık değilse normaldir.

Şu kodu şu şekilde değiştir:

if(tkn4.contains(a) {
    kontrol()
}

====>

if(tkn4 != null {
  if(tkn4.contains(a) {
      kontrol()
  }
}

Bu arada o "build" klasörleri ile işin yok. Kaynak kod /src altında bulunur.
