Can anyone help me to find out the problem??

Answer 1

Change your dependencies

dependencies {
 compile 'com.android.support:support-v4:19.1.0'
 compile 'com.android.support:gridlayout-v7:19.1.0'
}

Using the +, you are getting the last release.

Currently the last release is the compile 'com.android.support:support-v4:21 and it has a minSdk='L' because it is a preview release.

Use it only to test the android 'L' preview.

Answer 2

Try editing the following line to your Android Manifest file, like so:

dependencies {
    compile 'com.android.support:support-v4:21+' 
}

Then your project should build.

Answer 3

Change your dependencies in app/build.gradle to lower version

apply plugin: 'com.android.application'

android {
compileSdkVersion 20
buildToolsVersion "20.0.0"

defaultConfig {
    applicationId "com.eusecom.snowsmsden"
    minSdkVersion 16
    targetSdkVersion 20
}

buildTypes {
    release {
        runProguard false
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.txt'
    }
}
}

dependencies {
compile 'com.android.support:support-v4:20.+'
compile 'com.android.support:appcompat-v7:20.+'
}
