[vigyanabikshu1]

I fixed all bugs shown during, but not worked after changing the build tool,target sdk etc to 29.
build.graddle both library and project.

compileSdkVersion 29
buildToolsVersion "28.0.3"

defaultConfig {
    minSdkVersion 19
    targetSdkVersion 29
    versionCode 1
    versionName "1.0"
}
