many thanks for your help

old activities which inherit from AppcompatActivity work fine. but if I create new one ,it get the error . here is my gradle.build :

apply plugin: 'com.android.application'

android {
    compileSdkVersion 23
    buildToolsVersion "23.0.0"

    defaultConfig {
        applicationId "com.mkapp.apps.demo1"
        minSdkVersion 10
        targetSdkVersion 22
        compileOptions {
            sourceCompatibility JavaVersion.VERSION_1_7
            targetCompatibility JavaVersion.VERSION_1_7
        }
        multiDexEnabled true
    }
    dexOptions {
        incremental true
        javaMaxHeapSize "4g"
    }
    packagingOptions {
        exclude 'META-INF/LICENSE.txt'
        exclude 'META-INF/NOTICE.txt'
    }
    lintOptions {
        checkReleaseBuilds false
        // Or, if you prefer, you can continue to check for errors in release builds,
        // but continue the build even when errors are found:
        abortOnError false
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.txt'
        }
    }

You have this issue because you are trying to use onCreate (Bundle savedInstanceState, PersistableBundle persistentState), but this method is available only from API level 21.

I am able to reproduce the issue with this sample code on Android 4.4:

public class TourActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState, new PersistableBundle());
    }

    @Override
    public void onCreate(Bundle savedInstanceState, PersistableBundle persistentState) {
        super.onCreate(savedInstanceState, persistentState);
    }
}

And the issue is resolved removing every occurrence of PersistableBundle:

public class TourActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
    }
}

Check where you use PersistableBundle in your TourActivity and remove it or update your answer with the code of your activity.
