[bestshubhamever]

ERROR: Manifest merger failed : uses-sdk:minSdkVersion 15 cannot be smaller than version 16 declared in library [sun.bob:mcalendarview:1.0.0] AndroidManifest.xml as the library might be using APIs not available in 15
Suggestion: use a compatible library with a minSdk of at most 15,
or increase this project's minSdk version to at least 16,
or use tools:overrideLibrary="sun.bob.mcalendarview" to force usage (may lead to runtime failures)
