It doesn't show the images.It seems that it always loading the image.Finally I cant get the actual image as a output.
Anybody can help me if you know how to solve these.Thank You.
Firstly In my emulator there was a two app in the same name.I doesn't know that.
That's why I am getting these Exception at RunTime.
java.io.FileNotFoundException: /storage/sdcard/Android/data/com.gems.android/cache/http/ec1de446b4ed202c22d7c762f1746668.0.tmp: fstat failed: ENOENT (No such file or directory)
I solved these problem by uninstall the two same app name and install the currently worked project.
