    > Manifest merger failed : uses-sdk:minSdkVersion 8 cannot be smaller than version 9 declared in library [com.android.support:appcompat-v7:24.2.0] C:UsersAMANAndroidStudioProjectsMyApplication2appbuildintermediatesexploded-aarcom.android.supportappcompat-v724.2.0AndroidManifest.xml
    Suggestion: use tools:overrideLibrary="android.support.v7.appcompat" to force usage

  7. I have lots of troubles 🙁 first none of my PC were compatible with virtual devices, so I couldn't use the emulator, I tried to use a real device but it doesn't detect it even tho I followed the instructions 🙁 this is so frustrating it's been 3 dais of searching for fixes and I can't find any solutions to all these problems…

    It t says in red "No conected devices" "No debuggable Aplications"

  8. nothing shows up in the filter I made but it shows up in the "show only in selected application." is it necessary for onStart, onCreate, etc to show up in the filter I made?

  9. As specialist, I believe Devomobiron Secrets
    is actually great way to get money from your first iphone & android
    apps creation without any programming experience at all. Why not give it
    a shot? perhaps it is going to work for you too.

  10. Log.i doesnt work. :/ something so fundamental….I've done it like you but its running on the android phone

  11. An advice for anyone using a crappy PC like me, it's faster if u link ur phone with an USB cable and use debugging mode to use ur phone for testing instead of the emulator.
