Belirtilen adla eşleşen kaynak bulunamadı ('çizilebilir/simge' değerinde 'simgesiyle')

Question

Android'le yeni oluyorum ve gürültü düzeyini analiz edebilen bir uygulama yapmaya çalışıyorum ve yararlı bir kaynak buldum maalesef yukarıda belirtilen hatayı alıyorum. Tüm dosyalarımı ekledim, bu yüzden düzeltmek için herhangi bir ipucu gerçekten takdir edilecektir.

Bu, açık bir dosyadır.

0 bu kodu android:icon="@drawable/icon" aracılığıyla uygulamaya için simge belirlemek için çalışıyoruz.

Bu, res/drawable klasöründe bir icon.png img dosyanızın olması gerektiğini gösterir. Diğer bir deyişle, bir icon.png imgülü çizilebilir klasörün içine yerleştirilirse sorununuz çözülür. img dosya isminin icon.png olması zorunlu değil, ic_launcher.png gibi herhangi bir ad olabilir ..... o zaman bu gibi bir manifesto dosyanızı değiştirmelisiniz. android:icon="@drawable/ic_launcher"

ama img png formatı olacaktır.

sizin `drawable` klasöründe` icon.png` adlı bir dosya kaçırma gibi görünüyor
