I have been working on creating an Android app for a month now. Every time I have tried to run the app it crashes. I am having a very hard time reading LogCat and understanding what it is actually saying to me. So, I created a new project and copied some code from developers.android.com and tried running it, and the same thing happened. I figured it was the virtual device, so I looked up stuff on that and I found that it said I should have the SD card storage configured. So I did that as well. I still have the same problem, and can't run the app! I also have the developer option turned on within my phone as well as the unknown sources option. I only have two activities (MainActivity and Main2Activity)
There is no code in the MainActivity.java file, and there is nothing in the .xml file associated with them. I am trying to do the Up Navigation feature and this is what is happening.
Here is the output from LogCat when I debug the app in a virtual device. If I run the app rather than Debug it, I have a lot more errors but I can't post it because it goes over the max character count:
