java - My App wont compile and when it throws an error all my resource files are gone -

for reason whenver seek compile android studio project, keeps saying image "default" invalid. doesn't create sense because in xml file has no issue displaying when alter view design mode view. after compile, gradle throws issue , "r." turn symbol not found. i.e. whever did r.id.textview, r's turn reddish , can't alter back.

my errors:

error:error: invalid symbol: 'default' error:execution failed task ':app:processdebugresources'. > com.android.ide.common.internal.loggederrorexception: failed run command: /applications/android studio.app/sdk/build-tools/android-4.4w/aapt bundle -f --no-crunch -i /applications/android studio.app/sdk/platforms/android-20/android.jar -m /users/anuraag/androidstudioprojects/weather/app/build/intermediates/manifests/debug/androidmanifest.xml -s /users/anuraag/androidstudioprojects/weather/app/build/intermediates/res/debug -a /users/anuraag/androidstudioprojects/weather/app/build/intermediates/assets/debug -m -j /users/anuraag/androidstudioprojects/weather/app/build/generated/source/r/debug -f /users/anuraag/androidstudioprojects/weather/app/build/intermediates/libs/app-debug.ap_ --debug-mode --custom-package com.anuraagy.weather -0 apk error code: 1 output: res/drawable-hdpi-v4/default.png:0: error: invalid symbol: 'default'
