I had the common errors like when trying to setup the fb sdk such as ANDROID_BUILD_SDK_TOOLS ERROR and getbootclasspath() method error
but some of the solutions that people posted on SO has the minimum sdk as 14, instead of 9 (which is shown on the fb's guide). Now in my app's build.gradle file, if I use minSdkVersion 9 instead of 14, it wont work and it will say:
Execution failed for task ':app:processDebugManifest'.
Manifest merger failed : uses-sdk:minSdkVersion 9 cannot be smaller than version 14 declared in library
I have researched, but couldn't find the solution for using 9 because I want to support the app on Gingerbread.
